This car was visibly faster than anything I've seen before. Watching the speed gave me more of the sensation of watching a mach jet than a car. Just brutal.
To me it looked like the film had been speeded up. Astonishing.
It was about 6 seconds faster than 2nd place. Which is nuts on a track that short
The dust it sucked up made it look quick aswell
yeah, it looked like a gokart
@Life As Ya Know It it's both, the car was cornering faster than anything I've ever seen except for maybe an F1 car in a high speed sweeper
One of the maddest facts about the speirling that max Chilton mentioned in an interview was that with the downforce and traction control off it'll spin the wheels up to 200mph in 0.3 seconds
What does that even mean? That doesn’t make sense pal…
@@TheLogicprouser it's how fast the wheels spin in a burnout
@@WynnofThule so it can break traction in 0.3s? Is that 0.3s the time from pressing full throttle to the wheels breaking traction? Is that time actually impressive for an ev? Is there any other ev to reference that time against do you know?
I assume it means that the wheels spin to an effective speed of 200ph.
As in the necessary rotation that would be required for 200ph if it was retaining all traction.
@@FazeredTube ahhh ok yeah that makes sense cheers bud 👍 comment read like at any speed up to 200mph it could spin the tyres in 0.3s which didn’t make sense but it was just me 👍
The car looks like a toy going around corners. So planted and stable even at extreme speeds! So excited to see this tech develop further
This is the ONLY electric car which has caught my imagination and doesn’t seem like an exercise in marketing. Bravo !
It also sounds amazing
you mean the car created to to win, promote the company and help with a one make race series , to further fund car development.....so marketing
arent all cars "marketed" ?
Driven a Plaid ??
@@yrma_fletcher8953 I can’t think of any product which ultimately doesn’t have something to do with marketing, that is obvious and tedious to have to state. The point is that electric cars won’t save the planet as advertised and certainly don’t all catch your imagination in the same way as this tiny, fan ground effect, extremely fast electric car does.
They made so much progress from the last time.
For me, this is the most impressive track performance car I have seen in years. I am keen to continue following their progress.
Also thanks for the insight.
Got to be the most impressive road legal car ever, not just the sheer speed but the marvellous engineering
@@mileswhd1234 how is it road legal!?
@@alanmay7929 not sure if the road legal variant is fully a thing yet, but the one from FOS had a plate 🤔
@@mileswhd1234 it’s not road legal! Fan cars are not road legal! Plus what about safety????? That car is tiny compared to other participants lol…..
@@alanmay7929 google it, a road legal one is apparently going to be released later this year
Hands down the only car that excites me whenever I watch it's videos nowadays.
As a track focussed hyper car.. this thing is in a completely different league to the new AMG project one. This is aerodynamic engineering at its absolute best. Good video Martin. Thanks
Thanks Olli, Agreed!
I bet that most AMG project one, Aston Valkyrie, Koenigsegg Jesko, etc. cars will never be driven close to their full potential unlike porsches, supras, and miatas.
Considering how small the car is to carry a big battery and that it's not available to public, I can assume its only good for this types of runs(2 or 3 laps full send) Don't expect this to have long range or be 'consumer friendly', like the amg or aston.
@@sepg5084 Yes, those cars would mostly be purchased as investments and never driven in order to protect it's value.
@@rickyricardo2006 it's not exactly what I'd pick to go shopping, but it is street legal and has more than enough range to drive around town. But McMurtry is too small to build them in any quantity so there will probably never be more than a few hundred MAYBE a few thousand, optimistically. Sadly its meant for the discerning collector market
The Goodwood run was one of the most impressive things I've ever witnessed. I had no expectations of being mind-blown, but that I was.
Haha, mind-"blown"
Conceptually, this is the same as the Chaparral 2J Can-Am car, of 1970 vintage. It had problems, but was eventually outlawed because it was so much faster than any other car. This has been the story of a great deal of true innovation in motorsports.
Its just unnatural. Controlled aerodynamics like this will break ground effect over bumps. While its very fast in a turn. Because it relies on manipulating ground effect. If you break ground effect and 6 g in a sharp turn? One bump or curb or rib. Its dangerous
I designed a controlled aero car but in a completely different manner that wouldnt rely on ground effect but generate just as much downforce and be much more safe
@@treatb09 Show us your design, please?
@@treatb09 id like to see that design
I remember the Chaparral and remember they banned it as it smoked everything else. Glad to see it's making a comeback. This car was insane to watch at Goodwood.
@@treatb09 The Chaparral car had active skirts tied to the suspension in an attempt to minimize the effect of irregular surfaces.
Watching this car for the first time when it broke the lap record at Goodwood reminded me of the day I walked into a shopping mall and saw my first ever flatscreen TV. I had to walk around it a few times and touch it to help me believe what I was seeing. This car isn't just the best of its kind, it's a new kind. It's the future. 👏
Interesting to hear the Fans are variable too, you can match acceleration with Suction and /or have it off - similar to drag recover systems, great concept that shocked the motoring world
It’s the natural progression and what f1 would be if it were left open design wise. Not new tech by any means. Throw in active suspension, six wheels and rear steering and it’s still just using old banned tech.
We need more cars like this though. Actually showing what cutting edge was supposed to be, not hybrid bs..
Group B rally too. If left unchecked
@@Drewbyy hybrid and electric are the future man, it's inevitable. The instant torque and unmatched acceleration that even hypercars struggle to match. but some sadly linger on as the rest of the world progresses.
@@Drewbyyit's basically everything that we want from F1: smaller chassis to enable overtakes, no problems with dirty air and relatively (to F1) simple aerodynamics, make this thing a hybrid, and it would be a beast.
The acceleration from a stop was incredible to see. It was like seeing a bullet leaving the barrel of a gun.
Truly fascinating design .. Watching the race it was visibly tremendously quick .I won the Donnington GT championship in 1980 with a similar home built ground effects car . not a fan car .. but my design destroyed the opposition. so much so that the drivers in my class protested unsuccessfully my engine size. I keep telling the Mercedes team that they barely need any aero on their Ground Effects F1 cars. Silverstone cct would be the perfect high speed track to go for a low aero drag, high Ground Effects setup. I have a huge respect for your driver .. he must be super committed . The McMurtry Speirling is in a class of it's own .
How did you get into racing?
gma t50 makes more sense than this
@@kalmmonke5037 said no one ever.
@@ironmantooltime bev is cant be recyled many times, prius prime gets lower emissions unless both cars running on cleanly made elcrticity which is rare and even the itd take hundreds of thouands of miles to be better, e fuels and hydrogen are actually sustinable with nuclear energy, prius prime could run on those. even worse, electric is not as fun as gma t50, for example engine sound quality and its correlation with drivers input, manual gear shifting, more visibility of moving enviroment so more precived speed, etc
@@kalmmonke5037 by that logic a bmw m3 makes more sense than this.
What a brilliant and exciting piece of engineering! At first I thought it looked silly but that was my lack of imagination on display. Form follows function and all that.
Looks like the batmobile of the early 90s
I've never seen ANYTHING move like that car moved. It was faster in transitions and apex's than ANYTHING I've ever seen. It is a marvel of engineering.
Instant dream car. It's shape caught my attention. When I clicked the thumbnail I thought it was a toy. And I guess it kind of is. But when it turned out to be real AND a fan car, I was in love. I can only hope to see this car put into a Gran Turismo or something similar so that I have a chance to experience it. Because I know I'll never get the chance in real life.
The crazy thing about this car is that it runs a 7 second quarter mile when it's top speed is limited to 150mph
I've fallen out of love with cars a while ago, but damn. This car is exciting!
What a great video! Straight forward explaining of many technical aspects. Thank you!
What a bit of kit! It was astounding to see it at Goodwood, well done to all the development team and the driver. love a pocket rocket, and this is the ultimate!
I hope they start a racing series based on this car.
Can't. Imagine following behind this car and being sandblasted by it's fans output
I've noticed this car pop up in some suggested feed and admit that I mistook it for some bat mobile knockoff. So I'm pleasantly rewarded of being kicked in the head with a brilliant designing innovation that proved it's concept with pure numbers and shocked faces.
Yesterday i saw first time video with this machine ride, and i couldn´t believe my eyes how fast it is, it is surreal, it is really something whole new.
An amazing technology vehicle. I remember seeing it on a TV program in 2021, and thinking "Thats a Batmobile, if ever I saw one" !! It also goes like one as well, without the need for speeding the video up. Ot of the box thinking at its best. We'll done to the design team 👏👏👏
I was hoping you would do a video about it! Nicely done, Martin!
this was incredibly informative, and very much appreciated
And this thing is road legal?!?
Would love to see an F1 driver drive this around monaco, would suit that track aswell as it will be better in the low speed.
I doubt it. From reading their web site, they are saying that road version will be developed. However, I also watched TH-cam videos that someone claim that it is street legal.
@@catchnkill No, this current version is road going, hence the UK number plates...
@@zoidburg2975 I read news that their MD told Autocar after the event that they will build a street legal version. This one is not. The license plate there is for decoration only to draw attention that a street version will be built.
@@catchnkill That's a shame I hope the street legal one doesnt sacrifice performance, dont want a mclaren lauda like deal where they give it less downforce because normal road users wouldnt be able to handle it
Spa,eau rouge....merde!!!!
Can you imagine this at the pikes peak hill climb!!!! It would destroy anything. And also I would love if someone made a mod of this car for a sim racing game
A very very good explanation of this ground breaking car. Thank you.
Wow. Tremendous engineering... I am impressed. Thank you.
Awesome concept! It’s run at Goodwood was very impressive!
The redundant fan system is really impressive forethought. Really cannot imagine a non aircraft type guy thinking of that. Off the top of my head I can't think of many roadgoing cars that have redundant systems on really anything. Emergency systems maybe, but redundant? Are there any that I am not thinking of?
Some luxury cars have redundancy in ways that keep a broken vehicle operable.
For example v12s with separate looms for each bank so it can function on just half if needed
Redundancy is really not as important for road going civilian cars. If they break you pull over and call for help.
Military vehicles can have redundancies though.
Brake systems in cars are made so they’re split, with one hydraulic system working the front right and rear left wheel, and the other running the opposite corners. If one loop experiences a leak and stops functioning, the other will still work. The use of wheels on opposite corners helps keep the car going straight.
Brake lights and headlights include more than one lighting element, in case one burns out.
I wouldn't say that only an aircraft engineer could come up with a redundant system for a race car. For most cars redundant systems are not neccessary, or completely impractical, though there are still a lot of redundant systems, such as brake systems. But the problem with a fan car is that if you are pulling 3g's around a high speed corner and the fan fails, you are going to suddenly be ploughing straight, potentially into the nearest wall at very high speed. This is a major safety issue, and part of why they were banned in F1. I would say it's just due dilligence from the designers to include two fans into the design, though overall, the engineering of this car is indeed super impressive.
This is a marvel of EV track car engineering, first when I saw video of the record run at FOS I honestly was questioning if the clip has been fast forward, never seen anything go this fast around corners and coming out of corners. Using fans as downforce make perfect sense and the team at McMurtry really did a good job on the design.
In Top Gear video the representative said they are interested in making road cars as well, excited for that. 🔥🔥
they should have made it more experince focused car, making the front iwndshield pillars futhur away from driver and such things would give a bigger view outside the car, for preceived speed. and they shouldve used somthing like nissan e power drivetrain or maybe honda/toyota hybrid type of approach for lighter weight and some level of engine sound correlating with pedal position (torque output). a nissan deltawing setup overall maybe would have improved things futhur. freepiston drivetrain with air pressure regenerative braking could have been something that could also be applied to more affordable 4 seater car design i have
Fascinating machine. I did however wonder about the stability of the downforce subject to surface conditions, and I'm glad you brought up the kerb lift scenario as I was thinking the same. It seems like it could all of a sudden lose most of it's downforce from something as simple as uneven or poor ground surface. I'd love to learn more about how they've addressed this, and of course about the car overall. Thanks for the video!
This is my favorite car of all time. What a machine!
Great video man! Very informative!
Extremely well engineered car! I love it!
Excellent video. I learned things here about the car which I find not previously know.
Glad it was helpful!
Been waiting for this, awesome!
High quality video, thanks buddy 💪
Thanks for that!👍Very informative
Nice job 👌 thanx for sharing 👍
Thanks for the informative video. I am really impressed with the Speirling, from a technological as well as a conceptual perspective. Also it looks just great. It proves they should embrace fan driven down force in racing again. Killing it back in the Chaparral time was very much anti-innovation and a big shame.
Imagine modern f1 cars with this tech installed. Make them shorter, simplify aero and allow fans like this
@@tyler_bt3326 yes, smaller lighter and just as fast. If not faster.
Doing them as all electric is still in the future but active aero needs to be a thing in f1
Fans were banned for a very valid reason: stones, etc. being spat out the back of the car.
This car can have a fan as it was designed for hillclimbs, but a circuit racing car cannot
@@psk5746 They added a big air filter to prevent exactly that. See this vid at around 2:10. They are also making a road version which would have similar safety concerns, if not more so compared to racing.
Fan cars are not good for f1 or group racing because of all the debris it launches in the track lol….
Truly the future of motor racing. That fan ripping around Goodwood sounded amazing!
Great video buddy! 👏👏 just got my subscription!
That vehicle that changed the world!
Great work.
They should take it around the nurburgring
The batteries probably wouldn’t last long enough for a full out lap.
Nicely explained! 👍🏾
Brilliant piece of engineering, game changer
FANtastic piece of kit 👌
Well done, B. What a machine!
Thanks for this video man. never knew they used a van. an ambulance even
Awesome video thank you
Hopefully well get a pikes peak run of this project
Will it work on dirt surface? Pikes peak is combination of dirt and paved road. This vacuum system will play hell with a dirt surface. Traditional aero such as wings might be better. Wings can be as larger as needed and be front and rear and be active, they can adjust as needed while on track.
@@robert5 never realised it will be a big problem. But they seems to be great engineers. sure they will find a way.
@@robert5 I believe Pikes is bitumen all the way to the top these days
Very much worth to exist. Nice pioneership in tecnique. And fun and fast !
Interesting video. Thanks.
Absolutely brilliant. A modern well designed and thought out car to rival any combustion engined car. I was down by the start line at goodwood when the car took off and it was genuinely crazy fast. What that thing is like to drive is beyond imagination. I can only imagine it was a massive adrenaline rush. But witnessing it in the flesh and seeing it fly past was unreal. I think this is one that's going to take some beating and like the original Murray F1 it will be a game changer. Definitely one to watch.
gma t50 makes more sense
If all the stars align will this car run at Pikes Peak? We can only hope so but it seems an obvious thing to do.
Great video and amazing car.
Actually the Brabham fan car did not shoot out dirt, it was a lie because that way it was easier to get it banned based on safety reasons... Other than that, great video.
And also because the thought at the time was all teams would need a fan car and another non-fan car which would be ridiculously expensive
Imagine the improvements that can be made with this sort of base.
It's interesting that the concept is so different from Gordon Murray's concept for the T-50, which uses the fan to stop flow separation from its unique diffuser.
Actually the Speirling is using the fan like Murray's Brabham. But the T50 system is the result of further development...
The T.50 system is much more road friendly since it doesn't require a seal to the road. For track use, the vacuum cleaner setup is superior. That said, it also probably is way harder to get used to
Thanks for the explanation of the technology. The application appears to be for racing at this point with little apparent use for road cars.
More importantly, the ability to switch off DF on the straight allows the car to have lower ride height and/or a more compliant suspension without grounding out on the straights.
They have active suspension :d
If active aerodynamics were allowed in racing you could perhaps achieve nearly similar results without a fan and its energy needs.
@@basilb4733 not really. If understand correctly this design is very streamlined. Just fan provides negative lift. And RW was afterthought because they failed hit balance with just active skirts at high speeds. In other words design was too effective.
@@basilb4733 You have to remember that even traditional downforce is still technically powered by the engine since the engine is what's producing the speed needed to make it work. The fans on the other hand can be turned on or off as needed, and still work at low speed corners, where as traditional aero needs high speeds to be effective
Very nice video. Vacuum huh, works darn well.
Having watched this at goodwood , one can only say "wowww" what a car and performance. Now of only my car could corner like that lol
This car is bonkers. I absolutely love it.
Brilliant‼️
Next, the Nurburgring lap record please!
Can it go that far on one charge? (Not being particularly serious, by the way)
It wouldn’t do to well on the straight
I hope it finds its way to GT7 along with newer model cars from the manufacturers, in game!
I'm a big fan, of this car.
The car is actually quite efficient, much more so than my Model S, a little more than my i3, quite impressive.
Did you just..
You think you’re cool, huh?
Excellent video... The F1 Teams need to start this again..
Loved it, just loved it. I’ve been a huge fan of Gordon’s Brabham Fan Car. In fact in 1973 I ordered the last To Brabham BT40 Atlantic cars and racer in the John Players Atlantic series and the Yellow Pages Atlantic series in England from 1973-1976. The Brabham’s were useless. I had ordered Marches but talked into switching to Brabham’s by a friend who raced in the Atlantic in a March but they switched to Brabham after testing one. Good enough for him good enough for me. WRONG. To this day I’m still a fanatic for Grand Prix racing and still raced in the US UP UNTIL 20 years ago. I still own my Budweiser 96 Lola Indy car and it’s fully restored with the correct Ford Cosworth Engine. Again. I thing you did the most amazing job of designing this car, and
Far more simple then Gorden’s new car. I’m a big fan of your FAN CAR. Ted
worse experince than gordons car, just focusing on driving alone
Please include the link to your T50 video in your description as well as in the middle of this video... Hard to go back and find it there 😊
A race series with those cars would be dope 💟
♥️👍Thank you for Sharing
EXTRemely IMPRESSIVE! Sir 🏁gF NM/FL USA ☮️☄️
They need to make a bunch of these and have a one make race series- would be AWESOME!!!!
Amazing Machine!!!
A very well done explaination of what is probably a great big mess of math.
Jim Hall (designer of the Chaparral 2J) must love this car.
That’s such neat concept, downforce not dependent on speed.
What if you drive over a curb and the downforce drops very suddenly?
How smooth need the roads to be for this to work? Are the seals touching the street?
So would there no advantage to trying to shape the fan area in such a way that you could still have a large diffuser volume and front diffuser with flap like now newey’s X2014 has it? Does it get to a point where more downforce doesn’t actually help performance because you end up with more mechanical drag and the tire can’t use the extra load anyway? I’d love to hear more about the skirts, and how long they last and I really wanna see images of that van haha.
Yeah, me too. They talked about ceramic plates which they can drop. Would love to see that.
Of course you can shape the rest of the car so it produces additional downforce, but like I said in the video, they fully relied on the fans at the beginning and just recently discovered that it would be good to have some traditional downforce too.
For the underbody flow there would be the centre vacuum area in the way, but you could still generate downforce along the sides and guide the flow to the diffuser.
@@BSport320 Yeah my thought would be basically copying a 2022 F1 floor but instead of a plank have a vacuum sealed area behind the keel. Of course with a car this small that probably isn’t practical in terms of packaging. I can’t believe they say the next car they make will be smaller. Still it’s refreshing to see in a era of race cars getting longer and longer for aero.
@@BSport320 I wonder if the skirts are sprung? Could be quiet complicated to get them to seal and survive.
@@cademckee7276 did they actually say that? 😅 I’m all for making cars smaller and lighter, but this seems like it’s even smaller than a Miata or an Elise. I don’t think there’s much car left if you go smaller 😂
for a fan development platform, it needed to be sleek. just added downforce now.
can't wait to see what they come up with that when they put some more time into it. car is already insane tho!
This car sparked some new ideas in my mind. If you had a vacuum sealed chamber for each wheel you could reduce the wheel when resistance but tire temperature management would be more challenging but not impossible using radiation heat transfer. The suspension could be made much softer this way with the load applied directly to the wheels.
That has no much sense. 1. The smaller chamber size, the smaller downforce. 2. All the weight of the car, including generated downforce goes to the ground through 4 wheels. Not depending on what part of the car generates those forces.
Just a brilliant piece of engineering what a machine😎😎😎😎
Wonderful car!
its such an amazing machine. that combination of 1. ultra light weight, 2. insane horsepower and 3. extreme downforce. make it the best i ever seen
Not the only twin fan car up the hill. The Chaparral had twin kenlow fans each powered with two stroke engine at over 10K rpm the car it's self was power by big V8. It sounded wonderful!!
visually stunning.
First time I watched its Goodwood run, I thought the player was on fast forward, such a quick car.
this thing is Wicked! It's insanely rapid and fast! I've never seen a car that fast!
I absolutely love the Speirling!
Its a gorgeous thing. I would paint it deep purple metallic.
excellent choice!
I want one. looks like a small Batmobile and sounds awesome
It's incredible. it almost looks like it's a sped up video lol
Amazing engineering
If I recall correctly the Brabham BT46B fan car in fact didn't chuck stones and debris at other cars. Mario Andretti later admitted he'd lied about that to get it banned.
The portion looks good extremely curious and interesting. More super cats should be based on this design.
Hi!
Have you thought of making a video about the Lotus 88? It's a tad mystical because it's hard to find details about it on the web.
