He's one of the few that knows what he's talking about. Being involved since 1980 Larry has seen a few things. Definitely a smart man that knows what he's talking about
The sound will be different, but a powerful centerlock gun is extremely loud. I don't know what kind of guns they'll get, but F1 and LMP1 guns run at 25bars (362PSI), more than double of what the NASCAR guns run at. If you're at a street course, you're likely hear them over the cars if you're on the grandstands facing the pits.
@@shanevanorder2644 They haven't resembled car lot cars in a long long time. Chevy ran a Monte Carlo, an Impala, an SS and even a freaking Lumina before the Camaro. How many of those actually matched up with production cars?
Pit stops are now 80% less cool/impressive. Always loved watching the precision it takes to get 5 lugs off that fast. Now it's just one huge one that you'd have to be blind to miss. Just cause Larry says it'll look the same, doesn't mean it is the same. It's definitely more lame.
wow, I bet nascar has been making such a big deal about loose lug nuts lately to try and garner support for the one lug concept that most nascar fans are not so excited about.
@@whippy107 I don't see why going from 5 lug nuts to 1 center nut is going to make NASCAR worse. I've been waiting for this. Now cars most likely won't have to come in again if there is only one lug nut to focus on on each wheel. Losing two to three laps on the shorter ovals because of loose lug nuts and thus a loose wheel, forcing teams to pit again, has been extremely frustrating to drivers, teams and fans. And made even worse if the driver picks up a pit speeding violation in addition. I do have one major worry, though. With the shift from steel to aluminium wheel rims, how will these be affected during the longest races? Will the heat build-up cause problems with loosening and tightening the center lug nut? What if the lug nut is damaged/deformed during a race and the impact wrench fails to grip the lug nut during a pit stop, causing a lengthy delay or even a DNF? The new season will definitely bring some excitement and a few unknowns with it. Hopefully NASCAR can work out most of the kinks during current next-gen testing and off-season. Best regards from a long-time Norwegian NASCAR enthusiast.
@@scifiknut I'm not totally down on the single lug, but being a fan of the sport for over 30 years I appreciate the skill that the tire changers have had to develop and maintain in order to keep the teams competitive. Watching those guys change lugs so fast has been artful, and I suppose it's a shame others in the future won't be able to appreciate that moving forward. I'm also getting old and set in my ways LOL Cheers from the USA.
@@whippy107 Sure, I can totally understand. It's tradition. I've seen some of the TH-cam videos on how some feel that NASCAR has lost its identity. It's new and perhaps more politically correct drivers, it's the new play-off format etc. It's several things. I love to see the tight racing and as a European, watching the street circuit type of racing where they go left *and* right (😉) is closest to my heart. But oval racing is cool too, as long as one driver isn't running away with it from the start (that Kyle Larson is on a serious roll after joining Hendrick Motor Sports). But, that was a slight digression 🙂. Back to pit stops and lug nuts. Absolutely, when you see the cars breaking into their respective pit boxes and the tire changers, jackman and gasman move into position, it's a well choreographed and fluid maneuver in which they have to be spot-on. You have got to appreciate the many, many hours spent on hitting those lug nuts each and every time at high speed without missing a beat. Sure, there are some mishaps, but seeing the best pit crews pull off incredibly fast pit stops considering they are doing one side first and then have to sprint to the other side and repeat the job, that's really something to behold. It's perhaps something most of us take for granted, sadly, and we don't always see how much work and dedication that goes into being a pit crew member and not just the tire changers. For example, watching how the #9 team managed to sufficiently repair Elliot's car after he was shoved into the wall by #4 Harvick at the Charlotte Roval was quite amazing. I almost wished for Elliot to completely catch up with Harvick and do some retaliation, but then karma struck and Harvick took himself out. Can't deny I let out a chuckle and a squeal of joy 😉.
@@whippy107 I know what you mean. My dad was an IndyCar mechanic back in the 1960s, and one of his most prized possessions is a brass Proto wheel hammer with an aluminum handle. He hit the tail end of the years where they still used "knock off" wheel nuts, before going to the nitrogen air guns. You are right, a 5 lug pit stop is an art, but having been around the IndyCar and sporty car world all my life, I'm totally used to the center lock wheels. I even considered putting center lock wheels on my daily driver, however changing a flat on the side of the road would be a pain, so I decided against it.
Can we all please go back to Texas 2008 where Larry Mac himself literally said the reason they don’t go to single lug wheels is because what happens on pit road is a part of our sport. Only now to contradict everything he said, and try to reassure us. What a corporate pawn
I say let’s put a nipple on the bottom of the car then cut grooves in the track I think that might be gen 37 car better yet let’s have an old fashion raffle and the fans that pay the most can sit in the stands with giant controllers. Cmon people
I suspect there will be fewer two tire changes, and you still have to wait for fueling to finish in most stops. Expect a few mistakes leaving before fueling is complete at first.
Diffuser expands the air as it leaves the rear of the car. that helps the pressure differential above and below the car, that helps to suck the car to the ground which is the down force effect you get from it. then the expanded air is moving much closer to laminar flow out the rear of the car rather than air being forced up by a lip or wing. cleaner air behind allows for closer racing and less getting light in the rear from someone "stealing your air".
@@tomchrisfield7348 good point. I hope so because one of the fun things of watching NASCAR over Indy and F1 is their ability to bump into each other and keep racing.
The diffuser CAN add downforce. My question is going to be- if one car comes up and pushes another will the air "pack up" under the leading car??? This could make the leading car feel light, this could make for great passing and action, this could also be a problem. Great explanation though LGR
@@tomchrisfield7348 great question. We've seen mild damaged (very mild compared to nascar) cars in F1 suffer performance problems. Louis Hamilton I think had a couple races in recent years where 'floor damage" or diffuser damage changed his lap times from near fastest to mid pack. So I could see it being a problem at the 1.5mi or longer tracks. Maybe even bristol because it's so fast.
full of shit is more like it. Quoting the propensity of Aluminium to grow and shrink with temperature as a reason for a centrelock nut, the guy is talking to the fans that dont know thermal expansion from thermal underwear.0
The aluminum wheel / single wheel nut has been used for decades in Indy Car and F1 and IMSA sports cars. Jim France comes with many years of experience in IMSA so this configuration is not foreign to him. Neither is the rear air diffuser - this also has been used for a long time in IMSA, Indy Car and F1. Just because this is new to NASCAR doesn't mean that it's never been tried before. NASCAR is just catching up with other major motorsports.
@@Nathanpirath20 This is not for the "better". Its turned into a dumpster fire of whiners, woke drivers scared to death to speak their minds, dwindling viewership.
End of an era with no more lug nuts that have been 3M glued on the rims forever. I enjoyed so much doing that routine in Talledega years ago, they had a setup at the Amp Energy tent where you could try it and get timed, spent a lot of time at it. Glad I kept some nuts as souvenirs now that they are disappearing.
Glad I was able to watch when it was really NASCAR. So many different sponsors and dozens of drivers to pull for. Cars looked like normal cars and you could tell the difference on the track. They all pretty much look the same now. If it wasn’t for Chase Elliott I wouldn’t waste my time. Grew up a Bill Elliott fan.
@@southpaw578 I think GT racing is what they're going for more and I love it I mean if you watch GT racing those things look exactly like their road built counterparts just race cars
I've been a dedicated NASCAR fan for 48 years. Absolutely nobody ever cared about lug nuts until now because "Oh my god!!!" they are changing them. It's amazing how desperate some people are to complain. It's a RACING series not a tire changing contest.
I disagree. The 5 lug nut setup is what made pit stops so difficult. Missing a lug nut could absolutely tank pit stop times. Now with the center lug, tire changing is pretty quick, and now pit stop time will depend on the gas man essentially. I think a lot of people miss the iconic sound, but it also detracts from the skill of the pit crew and its affect on pit stop times, where a few seconds could decide where you came out in the pack
Larry just said something I've been saying for years. You can't control the law of physics and aerodynamics... Nascar's competition team thinks otherwise and that they can play God. Thank you Larry and hopefully Nascar will listen and stop changing packages every week
Agreed, NASCAR's constant tinkering with the package over the past 5+ years is what ultimately ruined the Gen 6 era for me. I thought 2013-16 was mostly fine, but from 2017 on, the package changes started getting ridiculous and made the racing a lot less enjoyable to watch for me.
i wouldnt say nascar is just to blame. there soo many crybaby ass newer generation of fans who cry and cry about everything cause it doesnt fit F1 or Indy style of racing. the same 2-3 dudes winning every time.
It's actually really cool that Nascar is legit trying to keep the costs down, Indycsr was pretty expensive, then they got dallara involved and at 1st it was expensive, but now $6mn will gets ya a whole season, thats what nascars trying to do, 40mn right now will gets ya a full season, if they can knock that down to 20mn HUGE WIN
Actually, Larry breaks down the new rear diffuser, he mentions the new 18” alloy wheels and center nut but doesn’t go into detail. The title is a bit misleading IMO.
The 1 lug nut pit is gonna make the hardest competing with other pit crew. Drive in the drive will be faster and might be safer for the crew. That's my guess.
The limiting factor has been, and will continue to be, fuel. Most of the time, the thing that prevents a stop from being faster is making sure you get enough fuel in the car. Since NASCAR fuel cans are gravity fed, there's not a whole lot you can do to speed that up, so, as long as it stays gravity fed, fuel will always be the limiting speed factor on pit road
I like these 18 inch wheel bases with the one lug nut thing right there. I'm not so sure about some fans, they may or may not like this. You know I'm ready for this Generation 7 cars to make their debut in the Daytona 500 right about now.
Hopefully it will be safer. I don't watch a lot of open wheel but what I've seen is if it's not on, the wheel will come loose before they even leave the pits. I don't know though.
@@lightfeather9953 yeah I'd assume it would. But since it's all aluminum, it will probably bend to heck and end a lot of days. I can see it becoming quite an issue already
@@cptcrunch8578 There will probably be some growing pains the first year, but really just about every top series uses center lug wheel locks, from IMSA/WEC to Indy and F1. There are occasional issues, but there aren't wheels coming off every other turn on every lap. I see it as a safer upgrade as the tire changer only has one lug to focus on.
Plus the aluminum won’t heat the rim as much so at short track you won’t have to worry about the brake heat in the wheels melting the bead in the tires
Thank you. Finally. The center lug nut will make it so much easier. With that being said, we have seen wheels refusing to come off several times, especially in F1. So it doesn't mean pit stops will always be a 100 % smooth ride.
wasn't it one of the Red Bull cars that had a serious issue with it being cross-threaded and they had to put the car in the garage and get a cutting torch to remove it....
Are the Aluminium wheels going to be made in different colors and styles where drivers can pick the rim look they want on their car? Or add the spinners that keep turnin when they stop?
The only other thing about the single lug that's more or less good is that there's less risk of having lost lugs be flung onto the track and kicked up by a car for safety reasons. it wouldn't be the first time a mechanic got hit by a lug that fell off
Nascar fans are always weary with change. I've been a fan since 2001 and the last 2 years have been the biggest change I've ever seen the sport go through. While conserned about what comes out I'm also very excited to see the potential Nascar is capable of. Hope for the best and appreciate the sport for what it needs to become.
nascar fans well the newer generation are the ones calling for these changes. most of us older fans want the cars to go back to being stock right from a dealer or factory.
Lots of base model cars still have steel wheels, almost no production cars have a centre lug nut. I don’t understand how that’s changing with production car technology?
They didn't link the center-lock with production car looks, just the 18" aluminum wheel. If they were on nothing but road courses I think they could probably stick with the typical 5 lug system, but at short tracks when the brakes are hitting 1500 degrees and that heat gets into the aluminum it creates a serious issue with getting the lug nuts off which is why they decided to go with the center-lock
How much crash testing has been done with aluminum wheels? I suspect the aluminum wheel of equal strength to the steel wheel won't be very much lighter. The center lug design eliminates the 2 tire stops for track position when they can change 4 tires faster than they can fuel. Some series don't allow changing tires while fueling.
I am interested on how they're gonna take off and replace the center lug. Will it fly off and a new one be in place already? That's a large lug to be throwing around. Will it lock onto the gun and then release after it's retightened. Will cross threading be an issue at All?
NASCAR keeps moving further and further away from what stock-car racing was at it’s greatest, but then again… If they won’t go back to what it was and (in my opinion) should be, at least they seem to be moving finally toward something I and many like me will be interested in. Seems like it’s becoming like an American version of touring car racing. Throw in some more road courses and I might actually become a fan for the first time since I was a little kid in the 80s/90s.
Wish Larry talked about one side having left hand threads.I just noticed it in that latest pit stop vid.I believe it's the right. Side has left hand threads.probably led to some confusion.
I think it's cute that nascar is discovering all this 80s tech for the first time. It's like watching my niece and nephew play an old video game for the first time. Like to them, they're living in the future. They don't even know what xbox live is so of course an NES has them enthralled. "Car of Tomorrow" has IRS? Sure nascar. Revolutionary.
How will the aluminum wheel hold up to a hit in the wall?Will it shatter and take out the body and suspension?What testing was done on the wheels for wall impact?
Think wheels changes will be about the same. With the single wheel nut you'll 1. Need more torque (some stock porches are in the 300 ft lb range), 2, left side will be reversed threaded.
It would not have worked prior to 2020 when NASCAR went to the uni-lug alloy rim that is much closer to being flush with the outside edge of the tire than the old 5 bolt steel rims were. Before the change, drivers knew that rubbing the wall with the the bulk of the weigh being against the rubber of the tire slowed them down more than the support of the wall allowed them to speed up.
@@King5150Ed I thought you bailed on the sport 20 years ago? Stands to reason you wouldn't care how they were going about their business 20 years later.... Is this your way of confirming that you are completely full of shit?
No wonder I stopped watching Nascar years ago and I certainly won't be returning to watch it now.. Continuing down the path of making it just like Continental racing. Lots of guys over the wall, long pits with lots of actions such as having to do all the lugs was a huge part of the sport to me. Took incredible teamwork to do all those steps together and get the stop as short as possible.
They have to figure out how to get the BBS wheel on correctly so they don’t come off. We had two wheels coming loose. The wheel changer need to mount it correctly so the lock nut works.
Sorry Larry but a Rear Diffuser does not clean up the air behind the car how can I say this is because I also am a fan of IMSA and F1. What I do see and fully believe will be a big problem is the falling down and breaking off of rear diffusers from bump drafting, and the general rubbing of front and rear bumpers in normal NASCAR racing. Additionally I have great concerns about NASCAR not only going from a 15” wheel to a 18” wheel but even more concerns with the use of aluminum wheels as well as the center wheel nut. The bigger wheel is going to decrease the sidewall profile or size and while yes it will allow for a slightly stiffer sidewall it also takes away the shock absorbing effect of the larger sideway this will in theory possibly slower the cars down which is the reason that F1 also is going to a larger rim diameter but F1 is going from a 13” wheel to 17 and 19 inch wheel if I am remembering the sizes correctly where as NASCAR is going from 15 to 18 inch wheel diameter. Additionally the width of the tires in F1 are much wider in F1 than NASCAR which will also play a major part in the impact of the change in wheel diameter. As for NASCAR going to an Aluminum Alloy wheel this is of most concern to me for several reasons all which mainly have to do with safety. To start with the steel wheels that all NASCAR teams use are relatively inexpensive and that is a good thing since each team needs to have enough rims for at least two races because of how the Goodyear tire program works. The simple version is post race all the tires a team got for that race are turned back into Goodyear while they are mounted on the rims and then sent to a facility for the tires to be dismounted rims washed and inspected for wear to lug nut holes, square/trueness to ensure they aren’t bent, as well as being inspected for other physical defects such as cracks. All of these inspections can be done visually with no problem because they are made of steel and the same is true for the new aluminum wheels except for cracks/stress cracks. Which is why F1 teams have the rims for there cars periodically x-rayed and they are scrapped after “X” many times tires are mounted on them. The difference is a F1 team has at most 100 rims and team budget that could fund two a 4 car NASCAR teams and still have money left over. A single car cup team needs to have around 175 rims so do the math for the how much the rim budget is going to increase and since a steel wheel basically is only replaced when a found to be no longer serviceable but the aluminum wheels in NASCAR like F1 are going to more than likely have a service life as well as needing to be x-rayed checked for cracks this is going to raise the cost of NASCAR cup racing on a series that has continued shrink it’s field size because of lack of race teams. Back to safety concerns about aluminum wheels and NASCAR cup racing as it is we normally see between 3 and 5 wheels a race season suffer a wheel center break out due to impact against another car or wall my question is how many do you think will happen with aluminum wheels or possibly worse yet chunks of aluminum wheels breaking off when hitting the wall or curb and go flying into the stands possibly hitting a spectator. Lastly a IndyCar or F1 car has far fewer pits stops than a NASCAR Cup car and it is not uncommon for them to cross thread a wheel nut /spindle and when that happens the car is retired in NASCAR currently teams will uses a rethreading die if a wheel stud threads are damaged because they have five and in truth only 3 are really needed and additionally if a lug or two is not tight but the others are it really does not matter but if a wheel nut is not tightened correctly well there is no chance of limping it safely into the pits. Personally I think think NASCAR is making a large mistake and will alienate even more of its core fan base and if they don’t attract replacements well it will continue to die a slow death but just faster
cool they went from 5 points of failure down to one! now hoping my fav driver doesn't have that 1 failure. Yeah I get that it is already a proven application. But it's gonna suck for someone when the threads get wrecked.
What happens when the 1 fastener is not put on tightly deliberately like they do with Lug Nuts to shave pit stop time. The wheel comes off causes a wreck & death of loose wheels taking folks heads off in the stands. You know they are going to see what they can get away with just like in tech inspections.
A single lug stop in FI takes around 3 seconds, they will be waiting on fuel anyways. Plus, what good would it do to leave a wheel loose on a single lug stop when it's guaranteed to fail? That would be akin to tightening only one lug on a 5 lug stop...
@@codymoe4986 Larry when he was covering races like DW a few years back was talking about how teams have deliberately left the pits with 4 or even 3 lugs on the wheel & may not be tight. The lugs is held on the rim awaiting the tire change with a rubber cement material like Permatex. Sometimes they get knocked off the rim by the air gun hitting one as he tightens them. They have shown they leave the pits with only 3 or 4 & do not pit till or if the wheel tears out the holes on the rim causing a bad vibration.
With the way the diffuser looks, it looks like bump drafting would damage it and that couldn't be good for it. And before you comment and say that you're sure they tested for that. Remember that 1 generation of car R&D didn't realize the front and rear bumpers didn't line up causing a ton of crashes and only lasted for 1 season. So no they may not have tested that.
It seems like it will be easier for the pit crews. Although, as a Elliott fan, I'm sure the 9 team will still find a way to f*** up on pit road during 80% of the season. Whether they win the title this season or not they desperately need to improve on pit stops this off-season (everyone including Chase).
Love listening to Larry Mac, but I kind of shook my head about the wheels. Says they're going to aluminum to be closer to production cars, then said because of aluminum they have to do the single nut. Kind of contradictory.
When was the last time you stepped on your brakes so often your brake rotors glowed bright red. I'm willing to bet never. The rotors on these cars glow on the entrance to pretty much every corner. Thats a ton of heat radiating into the rims.
Most production cars use Alloy wheels these day which is in line with what Larry said. Centerlock nuts are required because of the intense heat the rotors will generate. If you use five lugs, that heat will work a lot of those nuts loose. He's not contradicting himself, he just explained/presented it poorly.
I think you guys missed what I was saying, all I meant was he said they're going to aluminum rims to be more like production cars, but because of that they're also going to the single nut. Completely understand why, but I just think it's ironic they're doing something to be more like production but it causes a change that makes it less like production vehicles.
If they do it like F1 does it then the gun has a ton of LED lights on it. When they throw the wheel on; the nut is not torqued correctly so the LED's shoed Red (no crap, it's a loose nut). When the nut is torqued to the right spec then the light on the gun turns Green and they can move on to the next wheel or if that's the last wheel they let the car go. Every single other racing series has used a single giant Nut to hold on to the wheel since the 1960's. Point is that it forces every other part of the Pit Stop to be faster and much more competitive, leading to more competitive pit stops.
Seems to me with the center lug, which could speed up pit-stops the thing that may take the longest is getting a full fuel load. Wonder how many will leave the pit before getting a full fuel load in order to get better track position.... and later may end up running out of fuel later while on the track?
This new gen is going to put the final nail in the coffin for nascar. I haven’t talked to even one person who likes this car. That with this bs stage racing nascar has been doing for years… might as well move to heat races and a final main race. God damn nascar. I understand your dying as a sport. But damn…
If we wanted to watch Daytona prototypes we would watch them race at lemans and Sebring. Center lug wheels are not installed on one single domestically built vehicle so how is that American. Nascar has been dead for 10 years and just gets worse. They need drivers with personality not crappy cars.
Need to reconfigure Lug-nut gun to engage the new lug-nut to properly seat the Center (only) Lug-Nut per wheel. Seeing several loose wheels (each race) due to "Not TIGHTENING LUG-NUTS" to proper pounds per square inch. Pit Crew guys will get it figured out, but Man-O'-Man.. seen some Close calls already..!
Welcome to the 21st century NASCAR. But seriously, I'm looking forward to these cars and the tire companies have pushed change in F1 and NASCAR (Indy too??) with the larger wheels and lower profile tire. What wasn't mentioned in this short bit was set-up differences with the lesser sidewall and the adjustments available during a race.
Quite a few wheels will fall off to start with whilst they adjust to the centre lock wheels, they had several wheels come off in F1 when they banned mid race refuelling, there will be ill fitted wheel locks to start with
They are going from steel rim to alluminium because that's what the manufacturer is doing on production cars. What manufacturer in the series is using the center lock on production cars?? 🤔

Yeah. Sucks that NASCAR decided to do this
Let's be honest, half the teams are intentionally doing only four. ;)
I totally agree. I will definitely miss the sound of air gun hitting the 5 lugs
Xfinity and Trucks will still have five lug nuts.

NASCAR isn't the same! I liked the old days, not "cookie cutter" race cars of today! 😒
I suspect there will be fewer two tire changes, and you still have to wait for fueling to finish in most stops. Expect a few mistakes leaving before fueling is complete at first.
I think we will still see tire strategy based on sets available instead of track position as it is now.
Diffuser expands the air as it leaves the rear of the car. that helps the pressure differential above and below the car, that helps to suck the car to the ground which is the down force effect you get from it. then the expanded air is moving much closer to laminar flow out the rear of the car rather than air being forced up by a lip or wing. cleaner air behind allows for closer racing and less getting light in the rear from someone "stealing your air".
Is the diffuser going to be durable ? If a car gets rear-ended on a restart is it fixable, or is the car done, speed wise ?
@@tomchrisfield7348 good point. I hope so because one of the fun things of watching NASCAR over Indy and F1 is their ability to bump into each other and keep racing.
The diffuser CAN add downforce. My question is going to be- if one car comes up and pushes another will the air "pack up" under the leading car??? This could make the leading car feel light, this could make for great passing and action, this could also be a problem. Great explanation though LGR
@@tomchrisfield7348 great question. We've seen mild damaged (very mild compared to nascar) cars in F1 suffer performance problems. Louis Hamilton I think had a couple races in recent years where 'floor damage" or diffuser damage changed his lap times from near fastest to mid pack. So I could see it being a problem at the 1.5mi or longer tracks. Maybe even bristol because it's so fast.
CLOSE.. it speeds up and channels the air & the way it escapes (creating a low pressure point) pulls the rear down.

The aluminum wheel / single wheel nut has been used for decades in Indy Car and F1 and IMSA sports cars. Jim France comes with many years of experience in IMSA so this configuration is not foreign to him. Neither is the rear air diffuser - this also has been used for a long time in IMSA, Indy Car and F1. Just because this is new to NASCAR doesn't mean that it's never been tried before. NASCAR is just catching up with other major motorsports.

End of an era with no more lug nuts that have been 3M glued on the rims forever. I enjoyed so much doing that routine in Talledega years ago, they had a setup at the Amp Energy tent where you could try it and get timed, spent a lot of time at it. Glad I kept some nuts as souvenirs now that they are disappearing.

I've been a dedicated NASCAR fan for 48 years. Absolutely nobody ever cared about lug nuts until now because "Oh my god!!!" they are changing them. It's amazing how desperate some people are to complain. It's a RACING series not a tire changing contest.
I disagree. The 5 lug nut setup is what made pit stops so difficult. Missing a lug nut could absolutely tank pit stop times. Now with the center lug, tire changing is pretty quick, and now pit stop time will depend on the gas man essentially. I think a lot of people miss the iconic sound, but it also detracts from the skill of the pit crew and its affect on pit stop times, where a few seconds could decide where you came out in the pack
Larry just said something I've been saying for years. You can't control the law of physics and aerodynamics... Nascar's competition team thinks otherwise and that they can play God. Thank you Larry and hopefully Nascar will listen and stop changing packages every week
Agreed, NASCAR's constant tinkering with the package over the past 5+ years is what ultimately ruined the Gen 6 era for me. I thought 2013-16 was mostly fine, but from 2017 on, the package changes started getting ridiculous and made the racing a lot less enjoyable to watch for me.
i wouldnt say nascar is just to blame. there soo many crybaby ass newer generation of fans who cry and cry about everything cause it doesnt fit F1 or Indy style of racing. the same 2-3 dudes winning every time.
@@CertifiedForkLiftOperator69420 So it would be better for nascar to die?
It's actually really cool that Nascar is legit trying to keep the costs down, Indycsr was pretty expensive, then they got dallara involved and at 1st it was expensive, but now $6mn will gets ya a whole season, thats what nascars trying to do, 40mn right now will gets ya a full season, if they can knock that down to 20mn HUGE WIN
Actually, Larry breaks down the new rear diffuser, he mentions the new 18” alloy wheels and center nut but doesn’t go into detail.
The title is a bit misleading IMO.
The 1 lug nut pit is gonna make the hardest competing with other pit crew. Drive in the drive will be faster and might be safer for the crew. That's my guess.
The limiting factor has been, and will continue to be, fuel. Most of the time, the thing that prevents a stop from being faster is making sure you get enough fuel in the car. Since NASCAR fuel cans are gravity fed, there's not a whole lot you can do to speed that up, so, as long as it stays gravity fed, fuel will always be the limiting speed factor on pit road
Thank you for the sharing of the Good Larry Mac /Next Gen car/ NASCAR video
I like these 18 inch wheel bases with the one lug nut thing right there. I'm not so sure about some fans, they may or may not like this. You know I'm ready for this Generation 7 cars to make their debut in the Daytona 500 right about now.
@Kaio Bispo true
The one lug nut system is interesting, can't wait to see it on track
A lot of other series already use it
Everyone else uses it. Nascar just finally caught up, and about time. Better for racing

It’s particularly the reason F1 can pull off the sub two second pit.

Hope no one gets a "lose lugnut" penalty because a penalty at that point, would be the least of their worries lol
Hopefully it will be safer. I don't watch a lot of open wheel but what I've seen is if it's not on, the wheel will come loose before they even leave the pits. I don't know though.
@@lightfeather9953 yeah I'd assume it would. But since it's all aluminum, it will probably bend to heck and end a lot of days. I can see it becoming quite an issue already
@@cptcrunch8578 There will probably be some growing pains the first year, but really just about every top series uses center lug wheel locks, from IMSA/WEC to Indy and F1. There are occasional issues, but there aren't wheels coming off every other turn on every lap. I see it as a safer upgrade as the tire changer only has one lug to focus on.
We need Larry at F1 pre season testing lmao
Going to really miss 5 on 5 off stops. At least Xfinity and Trucks will still have them.
No car built in North America uses less then 5 lug nuts. Even the new corvette super car z06 still uses 5 lugs.
Plus the aluminum won’t heat the rim as much so at short track you won’t have to worry about the brake heat in the wheels melting the bead in the tires
Thank you. Finally. The center lug nut will make it so much easier. With that being said, we have seen wheels refusing to come off several times, especially in F1. So it doesn't mean pit stops will always be a 100 % smooth ride.

Are the Aluminium wheels going to be made in different colors and styles where drivers can pick the rim look they want on their car? Or add the spinners that keep turnin when they stop?
drivers never have gotten a say. owners would decide about color. I don't know if nascar will allow they to be painted or not
@@johnhaas2523 maybe torque thrust will make a rim for them. Those look good
The only other thing about the single lug that's more or less good is that there's less risk of having lost lugs be flung onto the track and kicked up by a car for safety reasons. it wouldn't be the first time a mechanic got hit by a lug that fell off
Like the diffuser for sure. I hope it does allow cars to close up and pass legitimately on big tracks
Cannot get over how good the mustang looks I love it
Bring on the new cars, going to be epic, Jeff in LA USA
Nascar fans are always weary with change. I've been a fan since 2001 and the last 2 years have been the biggest change I've ever seen the sport go through. While conserned about what comes out I'm also very excited to see the potential Nascar is capable of. Hope for the best and appreciate the sport for what it needs to become.
nascar fans well the newer generation are the ones calling for these changes. most of us older fans want the cars to go back to being stock right from a dealer or factory.
The 70s, 80s and 90s were so much fun! Now, just boring. I guess like us old folks.
The last time all the cars were equal, Jeff Burton led every lap at NHIS.
I wish that track would have been dozed and rebuilt. Still my least favorite one.
Lots of base model cars still have steel wheels, almost no production cars have a centre lug nut. I don’t understand how that’s changing with production car technology?
They didn't link the center-lock with production car looks, just the 18" aluminum wheel. If they were on nothing but road courses I think they could probably stick with the typical 5 lug system, but at short tracks when the brakes are hitting 1500 degrees and that heat gets into the aluminum it creates a serious issue with getting the lug nuts off which is why they decided to go with the center-lock
I was today years old when I realized NASCAR is becoming more like F1. Keep it five lug.
seriously? just because of the wheel lugs?
@@patrickbarton730 yes
Larry .. you caved to the man
And they wonder why the fans are leaving NASCAR
I love the car. The tail lights definitely are going to be modified in a few years for road course use along with headlights
How much crash testing has been done with aluminum wheels? I suspect the aluminum wheel of equal strength to the steel wheel won't be very much lighter. The center lug design eliminates the 2 tire stops for track position when they can change 4 tires faster than they can fuel. Some series don't allow changing tires while fueling.
Lets get closer to production models, My camry wheel has 5 lugs on it...
I am interested on how they're gonna take off and replace the center lug. Will it fly off and a new one be in place already? That's a large lug to be throwing around. Will it lock onto the gun and then release after it's retightened. Will cross threading be an issue at All?
The rims have the lug nut locked onto the rim so the lug nut and rim are one piece essentially
Yesterday Was A Good Year wasn’t it? Great Attires, additionally!

NASCAR keeps moving further and further away from what stock-car racing was at it’s greatest, but then again… If they won’t go back to what it was and (in my opinion) should be, at least they seem to be moving finally toward something I and many like me will be interested in. Seems like it’s becoming like an American version of touring car racing. Throw in some more road courses and I might actually become a fan for the first time since I was a little kid in the 80s/90s.
Thats the thing they need to go full aussie supercars with it and get out of the ovals if this is the direction they are going
Cornering speeds are going to be crazy with short sidewall tires.
Alex and Larry are so great at their jobs.
Wish Larry talked about one side having left hand threads.I just noticed it in that latest pit stop vid.I believe it's the right. Side has left hand threads.probably led to some confusion.
I think it's cute that nascar is discovering all this 80s tech for the first time. It's like watching my niece and nephew play an old video game for the first time. Like to them, they're living in the future. They don't even know what xbox live is so of course an NES has them enthralled. "Car of Tomorrow" has IRS? Sure nascar. Revolutionary.

@@Dougieboy08 No, but it takes a huge part of the excitement of pit stops away. its dumbing down things for the pit crews

Totally sick😎😎😎
Any hack can change that tire. It takes skill and experience to hit 5 lugs in a couple seconds.
They need to change the race format and make the stages obsolete.
Think wheels changes will be about the same. With the single wheel nut you'll 1. Need more torque (some stock porches are in the 300 ft lb range), 2, left side will be reversed threaded.
It would not have worked prior to 2020 when NASCAR went to the uni-lug alloy rim that is much closer to being flush with the outside edge of the tire than the old 5 bolt steel rims were. Before the change, drivers knew that rubbing the wall with the the bulk of the weigh being against the rubber of the tire slowed them down more than the support of the wall allowed them to speed up.
The five lug wheel always made nascar stand out on pit road. But I guess they too are following the trend.

Which way does the 1 lug nut turn to loosen, on the new gencar?
No wonder I stopped watching Nascar years ago and I certainly won't be returning to watch it now.. Continuing down the path of making it just like Continental racing. Lots of guys over the wall, long pits with lots of actions such as having to do all the lugs was a huge part of the sport to me. Took incredible teamwork to do all those steps together and get the stop as short as possible.
Well. Bye.
I'm liking the changes coming to nascar
They have to figure out how to get the BBS wheel on correctly so they don’t come off. We had two wheels coming loose. The wheel changer need to mount it correctly so the lock nut works.
Might as well call it formula one now
Kinda odd comparison considering it's obvious you have never seen an F1 race...
Rip 5 lugs. Everyone will miss you.
No I was looking at the tire rims I don't know what you're talkin about at the end there. :P
Maybe it's the camera angle but that diffuser looks like it'll drag going into high banked turns.
Sorry Larry but a Rear Diffuser does not clean up the air behind the car how can I say this is because I also am a fan of IMSA and F1. What I do see and fully believe will be a big problem is the falling down and breaking off of rear diffusers from bump drafting, and the general rubbing of front and rear bumpers in normal NASCAR racing. Additionally I have great concerns about NASCAR not only going from a 15” wheel to a 18” wheel but even more concerns with the use of aluminum wheels as well as the center wheel nut. The bigger wheel is going to decrease the sidewall profile or size and while yes it will allow for a slightly stiffer sidewall it also takes away the shock absorbing effect of the larger sideway this will in theory possibly slower the cars down which is the reason that F1 also is going to a larger rim diameter but F1 is going from a 13” wheel to 17 and 19 inch wheel if I am remembering the sizes correctly where as NASCAR is going from 15 to 18 inch wheel diameter. Additionally the width of the tires in F1 are much wider in F1 than NASCAR which will also play a major part in the impact of the change in wheel diameter. As for NASCAR going to an Aluminum Alloy wheel this is of most concern to me for several reasons all which mainly have to do with safety. To start with the steel wheels that all NASCAR teams use are relatively inexpensive and that is a good thing since each team needs to have enough rims for at least two races because of how the Goodyear tire program works. The simple version is post race all the tires a team got for that race are turned back into Goodyear while they are mounted on the rims and then sent to a facility for the tires to be dismounted rims washed and inspected for wear to lug nut holes, square/trueness to ensure they aren’t bent, as well as being inspected for other physical defects such as cracks. All of these inspections can be done visually with no problem because they are made of steel and the same is true for the new aluminum wheels except for cracks/stress cracks. Which is why F1 teams have the rims for there cars periodically x-rayed and they are scrapped after “X” many times tires are mounted on them. The difference is a F1 team has at most 100 rims and team budget that could fund two a 4 car NASCAR teams and still have money left over. A single car cup team needs to have around 175 rims so do the math for the how much the rim budget is going to increase and since a steel wheel basically is only replaced when a found to be no longer serviceable but the aluminum wheels in NASCAR like F1 are going to more than likely have a service life as well as needing to be x-rayed checked for cracks this is going to raise the cost of NASCAR cup racing on a series that has continued shrink it’s field size because of lack of race teams. Back to safety concerns about aluminum wheels and NASCAR cup racing as it is we normally see between 3 and 5 wheels a race season suffer a wheel center break out due to impact against another car or wall my question is how many do you think will happen with aluminum wheels or possibly worse yet chunks of aluminum wheels breaking off when hitting the wall or curb and go flying into the stands possibly hitting a spectator. Lastly a IndyCar or F1 car has far fewer pits stops than a NASCAR Cup car and it is not uncommon for them to cross thread a wheel nut /spindle and when that happens the car is retired in NASCAR currently teams will uses a rethreading die if a wheel stud threads are damaged because they have five and in truth only 3 are really needed and additionally if a lug or two is not tight but the others are it really does not matter but if a wheel nut is not tightened correctly well there is no chance of limping it safely into the pits. Personally I think think NASCAR is making a large mistake and will alienate even more of its core fan base and if they don’t attract replacements well it will continue to die a slow death but just faster
cool they went from 5 points of failure down to one! now hoping my fav driver doesn't have that 1 failure. Yeah I get that it is already a proven application. But it's gonna suck for someone when the threads get wrecked.
What happens when the 1 fastener is not put on tightly deliberately like they do with Lug Nuts to shave pit stop time. The wheel comes off causes a wreck & death of loose wheels taking folks heads off in the stands. You know they are going to see what they can get away with just like in tech inspections.
A single lug stop in FI takes around 3 seconds, they will be waiting on fuel anyways.
Plus, what good would it do to leave a wheel loose on a single lug stop when it's guaranteed to fail? That would be akin to tightening only one lug on a 5 lug stop...
@@codymoe4986 Larry when he was covering races like DW a few years back was talking about how teams have deliberately left the pits with 4 or even 3 lugs on the wheel & may not be tight. The lugs is held on the rim awaiting the tire change with a rubber cement material like Permatex. Sometimes they get knocked off the rim by the air gun hitting one as he tightens them. They have shown they leave the pits with only 3 or 4 & do not pit till or if the wheel tears out the holes on the rim causing a bad vibration.
We miss Davey Allison!!!!
Lug nut glued to the wheel? Or do they use the same one throughout the race?
Same one. The guns hold the nut till they reverse it to put it back on.
I just saw one video where they said one Aussie V8 Supercar team had used the same single lug nut for 6 years so they are apparently pretty durable
Nascar fans: wow only one lugnut to hold wheels on. Porsche and Ferrari: hold our pirellis.
With the way the diffuser looks, it looks like bump drafting would damage it and that couldn't be good for it. And before you comment and say that you're sure they tested for that. Remember that 1 generation of car R&D didn't realize the front and rear bumpers didn't line up causing a ton of crashes and only lasted for 1 season. So no they may not have tested that.
Wow NASCAR has a state-of-the-art 1980s car in 2021 , what will they do next? Maybe independent rear suspension
It seems like it will be easier for the pit crews. Although, as a Elliott fan, I'm sure the 9 team will still find a way to f*** up on pit road during 80% of the season. Whether they win the title this season or not they desperately need to improve on pit stops this off-season (everyone including Chase).
Love listening to Larry Mac, but I kind of shook my head about the wheels. Says they're going to aluminum to be closer to production cars, then said because of aluminum they have to do the single nut. Kind of contradictory.
When was the last time you stepped on your brakes so often your brake rotors glowed bright red. I'm willing to bet never. The rotors on these cars glow on the entrance to pretty much every corner. Thats a ton of heat radiating into the rims.
Most production cars use Alloy wheels these day which is in line with what Larry said. Centerlock nuts are required because of the intense heat the rotors will generate. If you use five lugs, that heat will work a lot of those nuts loose. He's not contradicting himself, he just explained/presented it poorly.
I think you guys missed what I was saying, all I meant was he said they're going to aluminum rims to be more like production cars, but because of that they're also going to the single nut. Completely understand why, but I just think it's ironic they're doing something to be more like production but it causes a change that makes it less like production vehicles.
Nothing can create down force without creating drag.
might as well call it NATCAR. these are touring cars now
The only thought I had when they said they were going to a one center lug nut is I see a lot of tore up cars in the future from a tire falling off
If they do it like F1 does it then the gun has a ton of LED lights on it. When they throw the wheel on; the nut is not torqued correctly so the LED's shoed Red (no crap, it's a loose nut). When the nut is torqued to the right spec then the light on the gun turns Green and they can move on to the next wheel or if that's the last wheel they let the car go. Every single other racing series has used a single giant Nut to hold on to the wheel since the 1960's. Point is that it forces every other part of the Pit Stop to be faster and much more competitive, leading to more competitive pit stops.
Seems to me with the center lug, which could speed up pit-stops the thing that may take the longest is getting a full fuel load. Wonder how many will leave the pit before getting a full fuel load in order to get better track position.... and later may end up running out of fuel later while on the track?
in reality it would speed up the pit stops but that's not what Nascar wants so the guns will be slowed down
Does anybody know the size or dimensions of the single lug nut? Anybody know how to get ahold of Larry Mac, I bet he knows. The man's is amazing.
This new gen is going to put the final nail in the coffin for nascar. I haven’t talked to even one person who likes this car. That with this bs stage racing nascar has been doing for years… might as well move to heat races and a final main race. God damn nascar. I understand your dying as a sport. But damn…
If we wanted to watch Daytona prototypes we would watch them race at lemans and Sebring. Center lug wheels are not installed on one single domestically built vehicle so how is that American. Nascar has been dead for 10 years and just gets worse. They need drivers with personality not crappy cars.
Need to reconfigure Lug-nut gun to engage the new lug-nut to properly seat the Center (only) Lug-Nut per wheel. Seeing several loose wheels (each race) due to "Not TIGHTENING LUG-NUTS" to proper pounds per square inch.
Pit Crew guys will get it figured out, but Man-O'-Man.. seen some Close calls already..!
The name on the tires may not have changed but it is a completely different tire.
Welcome to the 21st century NASCAR. But seriously, I'm looking forward to these cars and the tire companies have pushed change in F1 and NASCAR (Indy too??) with the larger wheels and lower profile tire.
What wasn't mentioned in this short bit was set-up differences with the lesser sidewall and the adjustments available during a race.
I'm so glad that NASCAR is embracing some of the F1 and IndyCar technology, and for improving the sport of racing in general
Why? They're moving even farther away from *stock* cars...
Quite a few wheels will fall off to start with whilst they adjust to the centre lock wheels, they had several wheels come off in F1 when they banned mid race refuelling, there will be ill fitted wheel locks to start with
They are going from steel rim to alluminium because that's what the manufacturer is doing on production cars. What manufacturer in the series is using the center lock on production cars?? 🤔
