Happy Sunday everyone!! If you're curious about how they tune the open diff so well, I have a separate video on the subject! Even the McLaren P1 has an open diff: th-cam.com/video/gBHmWZcnWwM/w-d-xo.html. And if you're into photos, videos, and nonsense that goes on behind the scenes, consider following on the Instagrammies: instagram.com/engineeringexplained/
Mercedes also has the open diff with the oppositional braking, when I put my E55 in Dyno mode the open diff really shows through, under heavy acceleration one wheel will get out of control.
I think using the brakes to create some torque to split is a clever solution. The antilock brakes are already there and the same components can be used to apply and release the brakes when there is wheel slip. You get a simpler differential and I doubt that more than 20% of the total braking potential would ever be needed to split enough torque to the other wheel and get past the slippage. Thanks for posting this and your earlier video on this.
something about this review that has an essence of that simple “look at this awesome car” element that the old To Gear had. Yes, big complement. Keep it up, Jason.
Man I love your positivity just hearing you say how good it is from where you came from and where you are now and just how happy you are made my day. Can’t wait to see the rest of the cars 😊
I never like convertables until I started driving. I was always worried about the numbers. Now I feel like I'm trapped in hardtop cars. I fell in love with the open air feeling
Would you do a video on the best bang for your buck performance tyre? I realise it's a difficult subject to measure and compare; but I would find it interesting to see whether the Michelin Pilot Super Sport Cup2's which are arguably the best performance tyre, would be the best value for money considering there extraordinary price.
I haven't had the pleasure of experiencing many high end tires but I do have the BFGoodrich sport comp 2 and they are the best cornering tire I've driven on. I have yet to even make them squeal around corners. Mind you t I've only driven them on the street so I can't push them to their full potential without getting in trouble. My only problem with them is that they are not good for comfort. They are so stiff that when you drive on grooved roads you feel the car follow them. Its really annoying but it is worth it if you are performance oriented. These are summer tires so I bought a second set of winter tires which is also great for grip. My 225/55/16 were only $101 per tire from tire rack plus shipping. they are definitely worth the price. oh yeah they are also great even in heavy rain, haven't hydro planed even once, making them good street tires.
But still, even the other cars that are similar don't rely on the brakes, they have electronically controlled differentials. Definitely not an ideal system. A supercar shouldn't be skimping on electronics.
+Engineering Explained. I have a quick unrelated question I hope you will answer. I have a 3.0 24v straight 6 n/a. I want to turbo in the future but i need a exhaust manifold now. My question is could I install a turbo manifold and fabricate a blanking plate with gasket to run on n/a with minimal to no power loss? Would it work?
Not a blanking plate, you would need to fabricate a downpipe that attaches directly to the manifold where the turbo would normally attach. Usually it's a square-ish 4-bolt pattern. Then when you get the turbo you remove that downpipe, put on the turbo and attach a turbo-specific downpipe to connect to the exhaust. Theoretically possible but I'm certain it would be less efficient than using an actual equal-length header.
Now while there is turbo lag at the bottom end, it compensates for it by having an 8000RPM redline. So your turbo-lag free range is between 4500-8000RPM, which is respectable. So realistically, when you're driving hard, you wont' notice the lag since you're gonna be in the higher half of the rev range.
Open diffs are ideal in mid engine rwd situations especially in racing unless you're doingl low speed corners, right? Lotus had open diffs standard with LSD options for years.
My favourite grey Wizard - can you do a video on why modern supercars are struggling to reach 200mph? Surely it cant just be down to aero. The McLaren F1 had 625hp and hit 230mph. The 812 SF has 800hp and can only hit 220mph. The Merc GT R has 600 and can't hit 200mph! WHAT IS GOING ON WITH MODERN SUPERCARS?!
aero does play a major role those are both classical coupes, not mid engine supercars not only are they much higher than the F1, but the difference in shape inevitably changes its balance and drag additionally nowadays manufacturers are going for more cornering stability, which needs downforce and wider tyres, instead of just outright speed
Great vid ! Please do a pop and bang remap video (what happens and maybe why/Why not)! Alså maybe how to determine if a used car has custom map installed or not. Can a car pop and bang with stock cat?
@Jason Discounting the practicality aspect of both cars and purely based on heart, would you rather buy the 570s or the F-Type SVR? Does your answer change if you take the practicality into consideration?
wanted to ask what brings most new supercar companies like pagani to borrow engines from amg and other brands like spyker, tvr etc from brands like audi, corvette etc respectively. even well known old brand aston martin is also bringing in amg to their engines. so what takes big supercar companies to borrow engines and not build?
Isn't the open diff with individual wheel braking effectively the same as a differential utilizing clutch packs? If anything, I would think this system is superior to clutch packs due to a small amount of weight savings and the fact that there are fewer places for things to break.
Too bad you didn't enjoy the ride. ;) I think if you edited out you smiling, you would have had a 30 second video. Fun car to drive on the road, with the exception of going in and out of steep driveways (and speed bumps). Even with the front lift ability, it is one low car. I think part of the reason it was so comfortable was because you had the touring seats. And yes, I would love to have one. Lotto here I come!
Ten years ago there were already good sports cars, Porsche, Ferrari, Lamborghini, Aston Martin. But McClaren bought in a totally new paradigm and this shook up the other sports car manufacturers. (Also Nissan GTR)
Hi. Pretty car. This is my first video. I have heard a lot of great things about your stuff and heard you hang out with Chris Fix. Very cool. Maybe sometime I will make it to SEMA. Looked like a great time. Heidi
You're half right. Supercars *CAN* have open differentials. But, supercars *SHOULD* have Electronic LSDs. This brake-vetoring that McLaren, Bentley, et al. are using is just a cheap cop-out for actual mechanical engineering. Case in point, One of the reasons McLaren depreciation is so bad is because they're, as my friend put it, "horrible to drive... little more than a blunt instrument" (and it should be noted, this individual owns both an updated 12C and a 458 spider). It's a car that is HORRIFYING to take to the limits. Chris Harris said that the P1 "was the first McLaren that is controllable past the limit," but he never had the confidence in the P1 that he had in the 918 and LaFerrari. Matt Farah spun the 570s press car, and he's not exactly what I'd call a "bad driver." That said, the 675LT I was in around Silverstone was fairly decent. I'd still prefer a 458 Speciale, GT3RS, or a Huracan Performante though. That 3.8l engine just has no character whatsoever. (but, it does have prodigious amounts of power)
....Neither do electronic LSDs. Mechanical LSDs (particularly viscous and clutch-driven) can overheat during extended track use. This will most often lead to the diff only wanting to lock one way. Ask anyone who's driven a modern Aston Martin on track. Electronic LSDs tend to run significantly cooler than traditional viscous and clutch-driven differentials. They also have infinite variability which becomes increasingly important as you get into stickier tire compounds. Helical differentials (like the one you'll find in the FRS/BRZ/86) are an exception amongst mechanical diffs, but they're often a bit heavier and more cumbersome than the other types.
Personally, I'd go for some form of mechanical LSD, but nevertheless you are completely right. McLaren just don't have the stones to admit that they made a mistake. From what I remember, their main argument for using this whole brake-steer technology is that it is comparatively simpler then any kind of LSD, but that statement is rubbish - for reasons that I mentioned in another comment I made earlier...
Braden McHenry It's not about it being bad to drive, it's that torque vectoring by braking as opposed to proper LSD puts way more heat into your brakes, which is a terrible thing for track days.
Is that a spray bottle of pink stuff to keep the car all shiny and pretty looking? Please tell me that it's really a cup holder and McLaren didn't put that specifically in the car so you could pretty it up at a moment's notice.
I know driving these super cars are exciting, but I'm kindda prefer to watch videos on average cars that most people can buy. Like your S2000, Crosstrek.
The open diff has to be an advantage in the rain/snow, in town, on the freeway, 2 lane black top, etc. If it were truly just a track car I would venture a not guess and say there would be no traction control or open differential. Idk if you have driven a posi with HP in the rain/snow? It's more then a handfull, add turbo lag, ummm yeah a freakin nightmare.
Considering that you can still modulate individual wheel speeds while having some form of LSD fitted by means of brake bias (which is what McLaren wants to do), I can't understand why they - who strive to be at the forefront of automotive technology - decide to use the inferior open-diff setup? Their main argument, that it is mechanically simpler, and therefore more reliable to use an open-diff in conjunction with brake bias, is rubbish... (They call it "brake-steer", but it works by changing the lateral bias on the rear brakes, so I just say "brake-bias", because I am referring to the action of using the rear brakes in place of an LSD, and not necessarily the system as a whole) First off, this is McLaren, and when was the last time you heard of them doing something so it was simple/cost-effective rather then doing something so that it worked properly? Secondly, that whole brake bias system is WAY more complex then any LSD I've ever seen - especially when you take into account that you need sensors to measure individual wheel speed / brake force / brake line pressure (etc.) as well as all the computational power needed to make use of all that data! Just imagine how many possible points of failure there are! *O_O* Also, even if you used the 'fastest' electronic equipment available, there would still be some form of delay between an event at the wheels, and an action taken to account for it. Now compare that to something like a Torsen LSD that, using its purely mechanical "brain", locks up instantly* should one of the wheels start to spin up (of course there is a minute delay, but it is far less then any electronic equivalent - as far as I understand anyway).
The main benefit I see is more lively steering in tight cornering. My guess is that went too far when designing the chassis and suspension to eliminate some undesirable oversteer that mid engine cars can have, and they ended up having to compensate for that through an open diff.
Brodie Bennett brake systems like this really are less complex than an LSD system. There are no extra sensors and parts in a system like this, the car already has ABS sensors that can calculate wheel speed. Processing power is very abundant in cars and you don't need some huge complex computer to calculate how much a wheel is spinning faster than the other. It's pretty simple really. Computers are cheap and when is the last time you personally saw a computer fail in a modern vehicle? Reviewers and racers running the McLaren's on racetracks are not complaining of brake fade and the front brakes do the majority of the work anyway. A system like this allows you to modulate exactly how much power is being put down at each rear wheel.
Brodie Bennett even my 2000 BMW 3 series has this system.... It's nothing new and it's not complicated at all. And every Sensor you mentioned is Standard in 80% of todays cars But still, it's weird that Mclaren doesnt just use an LSD, Sounds just wrong
Walter Black it may be at 4k, but the engine isnt loaded. When the engine is under load you will get more exhaust than you would just cruising at the same rpm.
I think there are plenty of cars featuring ESP/ESC that apply brake to avoid a single wheel spin, am I wrong? It's a cheap but good replacement for a LSD. Anyway my car does not have ESP. :-(
"Buffeting" Ok James May...Here's a test. Put one wheel in the gravel facing up hill and goose it. I can almost guarantee you that torque vectoring is BS. The track gives almost equal traction for all wheels all the time. That's great, its marketed as a street car so find out for us.
Happy Sunday everyone!! If you're curious about how they tune the open diff so well, I have a separate video on the subject! Even the McLaren P1 has an open diff: th-cam.com/video/gBHmWZcnWwM/w-d-xo.html.

Dude, you are having too much fun.....great job...
Change gear....!!!!
Engineering Explained love your show. But GS-F felt good being all natural. And as much as I like stats, nothing feels better than natural power. :)
is it harmful to put your manual car in gear while parking on a hill in case of a handbrake's failure ? thanks

N Moran that had me rollin
God I love how simple that interior is
It will probably age pretty well. BMW's minimalist interior design in the 2000's is paying off tremendously.
Agreed! Luxury & supercars don't have to be overcomplicated just to set themselves apart.
What? But where will you keep your champagne glasses chilled if not your car?
Mercedes also has the open diff with the oppositional braking, when I put my E55 in Dyno mode the open diff really shows through, under heavy acceleration one wheel will get out of control.
are you saying the system works good or bad?
open diff = bad. of course by removing the diff you lessen weight, but the car can't drift or slide very well.
I think using the brakes to create some torque to split is a clever solution. The antilock brakes are already there and the same components can be used to apply and release the brakes when there is wheel slip. You get a simpler differential and I doubt that more than 20% of the total braking potential would ever be needed to split enough torque to the other wheel and get past the slippage.
Thanks for posting this and your earlier video on this.
I love this guy, so much information and he has hilarious moments. good video
dude your hard work has taken you a long way congratulations
something about this review that has an essence of that simple “look at this awesome car” element that the old To Gear had. Yes, big complement. Keep it up, Jason.
I like that you show gratitude and humbleness to where you are in life. You deserve the success, keep doing what you're doing :)
Jason, watched this w my 6yo daughter. You driving in the wind, she said you looked like Han Solo.
Tell Princess Leia that she's rad and I'm proud to have her viewership!
You're doing fathering right if she knows Han Solo.
It was good to meet ya, and hang out
Damn I love Oregon, the driving reviews are icing on the cake with all them trees
So beautiful!
Agreed, love Oregon, wish I were still home sometimes. Former resident of Toledo.
You should test more cars like this, it was more informative and interesting than many reviews
Man I love your positivity just hearing you say how good it is from where you came from and where you are now and just how happy you are made my day. Can’t wait to see the rest of the cars 😊
He got one of those iconic mythbusters "this is what I do for a living" smiles
I like how the picture-in-picture has a rounded corner. Great detail
What a beautiful way to start my day. Thank you for that.
I never like convertables until I started driving. I was always worried about the numbers. Now I feel like I'm trapped in hardtop cars. I fell in love with the open air feeling
good for you, love the channel... best of luck keep em coming
Would you do a video on the best bang for your buck performance tyre?

i had the Michelin but i tried the Pirelli Pzero and i prefer those
I had exactly the same opinion on convertibles as well, until one day I drove an S2000. The open top experience is really something special
So your carbon ceramic breaks will wear way faster with that open diff... right?
Can you please do a video explaining the benefits and drawbacks of a full float axle?
If you're still doing your own work on the S2000, I'd love to see more videos of what you're working on
Can you do a video on how exhaust expansion tubes, like used on motorcycles improves per performance and how much gain can be expected?
I love when you try to critique then put your foot down, smile and all is well again.
So streetspeed 717 spent $200k on a car that has an open diff?
Lukas Rosa Yup
What's open differ??
He's not 17. He's like 23/24.
it's not a traditional open diff.
But still, even the other cars that are similar don't rely on the brakes, they have electronically controlled differentials. Definitely not an ideal system. A supercar shouldn't be skimping on electronics.
What is the benefit of using an open differential with break slip control versus a limited slip differential?
+Engineering Explained. I have a quick unrelated question I hope you will answer.
I have a 3.0 24v straight 6 n/a. I want to turbo in the future but i need a exhaust manifold now.

Then when you get the turbo you remove that downpipe, put on the turbo and attach a turbo-specific downpipe to connect to the exhaust. Theoretically possible but I'm certain it would be less efficient than using an actual equal-length header.
can you please do a video on how OVERRUNNING CLUTCH works
(the one that is used in starter motor to prevent armature from overspeeding )
'TC coming in so I dont kill myself' *looks out window like bad boy*
You clearly had a lot of fun with this car and it made for a good video.
Now while there is turbo lag at the bottom end, it compensates for it by having an 8000RPM redline. So your turbo-lag free range is between 4500-8000RPM, which is respectable. So realistically, when you're driving hard, you wont' notice the lag since you're gonna be in the higher half of the rev range.
"v8s sound better, thats the story there" Love it
Need an engineering explained on modern cars that brake like that on their own and also the input from the driver
Didn’t you do a video on the p1 earlier? Or is that this car?
Yes, specifically about how the diff works (linked in pinned comment).
20 years ago I was 25. 12 years ago, you were---. Oof. Well, keep up the great work! Love your channel!
Good job, we wanna see more content like this.
Open diffs are ideal in mid engine rwd situations especially in racing unless you're doingl low speed corners, right? Lotus had open diffs standard with LSD options for years.
I've been in that room at the very end before. I don't remember where it is, but I remember being there on a school field trip years and years ago.
Beautiful creation overall.
Lol funny, informative and enjoyable video; and a mention to Chris Harris, another car legend. Well done EE.
Jason, is it good for the car if you inch forward with the Mclaren?
My favourite grey Wizard - can you do a video on why modern supercars are struggling to reach 200mph? Surely it cant just be down to aero. The McLaren F1 had 625hp and hit 230mph. The 812 SF has 800hp and can only hit 220mph. The Merc GT R has 600 and can't hit 200mph! WHAT IS GOING ON WITH MODERN SUPERCARS?!
aero does play a major role
those are both classical coupes, not mid engine supercars
not only are they much higher than the F1, but the difference in shape inevitably changes its balance and drag
additionally nowadays manufacturers are going for more cornering stability, which needs downforce and wider tyres, instead of just outright speed
You did a lot of videos lately involving turbocharged engines, it would be cool if you could do one about sequential/compound turbo systems :)
Is this a torque convertor or DCT or Seq ?
Great vid ! Please do a pop and bang remap video (what happens and maybe why/Why not)! Alså maybe how to determine if a used car has custom map installed or not.
Can a car pop and bang with stock cat?
I especially like how it has the Star Trek badge all over.
I know it's not really ENGINEERING, but would you do a video on popup headlights? Why they came around, why they went away, etc.
@Jason
Discounting the practicality aspect of both cars and purely based on heart, would you rather buy the 570s or the F-Type SVR?
Does your answer change if you take the practicality into consideration?
wanted to ask what brings most new supercar companies like pagani to borrow engines from amg and other brands like spyker, tvr etc from brands like audi, corvette etc respectively. even well known old brand aston martin is also bringing in amg to their engines. so what takes big supercar companies to borrow engines and not build?
Is the steering light?
Isn't the open diff with individual wheel braking effectively the same as a differential utilizing clutch packs? If anything, I would think this system is superior to clutch packs due to a small amount of weight savings and the fact that there are fewer places for things to break.
Too bad you didn't enjoy the ride. ;) I think if you edited out you smiling, you would have had a 30 second video.
Fun car to drive on the road, with the exception of going in and out of steep driveways (and speed bumps). Even with the front lift ability, it is one low car. I think part of the reason it was so comfortable was because you had the touring seats. And yes, I would love to have one. Lotto here I come!
What track did you use?
Ten years ago there were already good sports cars, Porsche, Ferrari, Lamborghini, Aston Martin.
But McClaren bought in a totally new paradigm and this shook up the other sports car manufacturers.

“Or there’s a Honda nearby” brilliant
Hi. Pretty car. This is my first video. I have heard a lot of great things about your stuff and heard you hang out with Chris Fix. Very cool. Maybe sometime I will make it to SEMA. Looked like a great time. Heidi
I learned in an 01’ Ford Taurus, but it has.A semi truck horn
You're half right. Supercars *CAN* have open differentials. But, supercars *SHOULD* have Electronic LSDs. This brake-vetoring that McLaren, Bentley, et al. are using is just a cheap cop-out for actual mechanical engineering. Case in point, One of the reasons McLaren depreciation is so bad is because they're, as my friend put it, "horrible to drive... little more than a blunt instrument" (and it should be noted, this individual owns both an updated 12C and a 458 spider).

I'd still prefer a 458 Speciale, GT3RS, or a Huracan Performante though. That 3.8l engine just has no character whatsoever. (but, it does have prodigious amounts of power)
Supercars shouldn't have electronic LSDs, they should have proper, mechanical LSDs that don't cook your brake pads on a trackday
....Neither do electronic LSDs. Mechanical LSDs (particularly viscous and clutch-driven) can overheat during extended track use. This will most often lead to the diff only wanting to lock one way. Ask anyone who's driven a modern Aston Martin on track.

"yeah i don't really like convertibles." *owns an s2000
We both seem to be greying at an early age. Helps me feel not so bad about mine
My cousin is 22 and he's already graying. Frankly, I feel that I may start graying in a couple years as well.
You need to drive the new Ford Taurus. I have an SEL. It's the beautiful combination of comfort and power. You may be surprised
What is this press event?
Mercedes-Benz has the ESP that manipulates the brakes to controls the open diff to send power to stagnant wheel and brake the free spinning wheel.
Wow, I smelled the burn from that Honda reference. Brutal.
Is that a spray bottle of pink stuff to keep the car all shiny and pretty looking? Please tell me that it's really a cup holder and McLaren didn't put that specifically in the car so you could pretty it up at a moment's notice.
So how do you drift with an open diff?
oi weld the diff
Ok, ok, you convinced me. I'll save a little and buy one.
suggestion for next time, do all this on the track and show us what you are talking about, then you will be the next chris harris :)
I know driving these super cars are exciting, but I'm kindda prefer to watch videos on average cars that most people can buy. Like your S2000, Crosstrek.
Wow Jason cant believe you learned to drive when you were 38 y/o! Haha, glad you had fun in the mclaren, I’m definitely jealous...
I'm clueless with an open differential is still enjoyed the video jealous you got to drive a
FREAKIN McLaren Spider......😲
You scored a McLaren, woah man. That couldn't have been easy to procure
Almost as much HP as modern SUVs Kappa
Hardtop goes up, hardtop goes down. Can't explain that!
I still can't get used to "nii-san"
Probably shouldn't visit Japan then.
The open diff has to be an advantage in the rain/snow, in town, on the freeway, 2 lane black top, etc.
If it were truly just a track car I would venture a not guess and say there would be no traction control or open differential.
Idk if you have driven a posi with HP in the rain/snow? It's more then a handfull, add turbo lag, ummm yeah a freakin nightmare.
the only mclaren that caught my attention was the 675LT, the rear is beautiful, but I still prefer the Lexus LF-A lol
how does this acceleration feel compared to Tesla Model S P100D?
Gotta love a nice rigid monocoque.
Considering that you can still modulate individual wheel speeds while having some form of LSD fitted by means of brake bias (which is what McLaren wants to do), I can't understand why they - who strive to be at the forefront of automotive technology - decide to use the inferior open-diff setup?

(They call it "brake-steer", but it works by changing the lateral bias on the rear brakes, so I just say "brake-bias", because I am referring to the action of using the rear brakes in place of an LSD, and not necessarily the system as a whole)
First off, this is McLaren, and when was the last time you heard of them doing something so it was simple/cost-effective rather then doing something so that it worked properly? Secondly, that whole brake bias system is WAY more complex then any LSD I've ever seen - especially when you take into account that you need sensors to measure individual wheel speed / brake force / brake line pressure (etc.) as well as all the computational power needed to make use of all that data! Just imagine how many possible points of failure there are! *O_O*
Also, even if you used the 'fastest' electronic equipment available, there would still be some form of delay between an event at the wheels, and an action taken to account for it. Now compare that to something like a Torsen LSD that, using its purely mechanical "brain", locks up instantly* should one of the wheels start to spin up (of course there is a minute delay, but it is far less then any electronic equivalent - as far as I understand anyway).
The main benefit I see is more lively steering in tight cornering. My guess is that went too far when designing the chassis and suspension to eliminate some undesirable oversteer that mid engine cars can have, and they ended up having to compensate for that through an open diff.
Brodie Bennett so the price is lower for the mass market of people who dont even know what a diff is and just want to show off
Brodie Bennett brake systems like this really are less complex than an LSD system. There are no extra sensors and parts in a system like this, the car already has ABS sensors that can calculate wheel speed.

Brodie Bennett even my 2000 BMW 3 series has this system.... It's nothing new and it's not complicated at all.
And every Sensor you mentioned is Standard in 80% of todays cars
But still, it's weird that Mclaren doesnt just use an LSD, Sounds just wrong
Its so clever that not a single one of the race cars or track cars run an open diff and get a mechanical lsd.
People who doesn't know Jason: "Rich kid driving his parents' car"
As an Electrician, I hope to one day buy one of these myself🙏
patrick henry but I'm a Junior in High school right now😂☹
Charge. Ha
Why do you have turbo lag if you're already at 4k rpm?
Walter Black it may be at 4k, but the engine isnt loaded. When the engine is under load you will get more exhaust than you would just cruising at the same rpm.
every other video it seems like you hop the oregon-idaho border lmao
+Sean Person I’m all over the place haha!
It's interesting that you compare it to the Nissan GT-R since the McLaren 3.8L v8 is based off a Nissan motor.
So the McLaren open diff works like Porsche Torque Vectoring, applying pressure in the inner wheel brake
You had a 95 Ford Taurus? That's what I started with. GL, The dark metallic blue.
I think there are plenty of cars featuring ESP/ESC that apply brake to avoid a single wheel spin, am I wrong? It's a cheap but good replacement for a LSD. Anyway my car does not have ESP. :-(
Is it weird that I was expecting you to talk about its, "Weird quirks and cool featured?"
I'm so jealous. Great video

That's the Aston Martin color to me :/
"Buffeting" Ok James May...Here's a test. Put one wheel in the gravel facing up hill and goose it. I can almost guarantee you that torque vectoring is BS. The track gives almost equal traction for all wheels all the time. That's great, its marketed as a street car so find out for us.
0-60 in 3.1 seconds Jesus. That's 488 and RWD Huracan territory. Well done McLaren.
Thanks 😁
