This car goes from 0-62 miles per hour in 0.956 of a second. This is the classic acceleration test, one that we all grew up using to compare cars.
A Formula 1 car will do it in about two and a half seconds, the fastest production car - a Rimac Nevera - will do it in 1.7 seconds and my trusty old VW Passat will do it in about 8.
But a group of students from AMZ Racing based at the Swiss university, ETH Zurich, made a car accelerate faster than anything else in the world - and smashed through the previous record of 1.46 seconds.
So, I spoke with Eloi Roset from AMZ Racing to understand exactly how these ambitious students approached this crazy project, what challenges they needed to overcome and how they engineered a car that accelerates more than twice as quickly as an F1 car.

Top fuel dragsters use tricks that you can't use for this. They use glue on the track to increase traction and tires that get bigger as they accelerate. Not using these tricks you can't accelerate past 1G. It's also why this car needed fans.

The best way to add downforce was banned by the CanAm series in the early 70's (the analogue was mentioned in the video). Electric actively sucking the car to the track. I'm still disappointing that no racing series embraced that method. I'm so enthused that these students saw the benefit of that and did all of the work needed to bring their vision to fruition. It's also good to see Citeron's work in hydraulic suspensions still being referenced in modern race cars. refrenced

Of course bicycles don't compare to fast cars. I'm watching everything I can about aero advantages to maybe apply to my build. This little car is rad. Closest thing would be the McMurtry Speirling. Love this. One thing I've been researching is surface characteristics and their effect on wind resistance. I've built my own disc wheel covers, modified the frame to optimize rider position, wheelbase, and power delivery.

The Lamborghini on my wall was a v12 with 4 valves per cylinder, the Quattro valve. It did 9-60 in 5.0, I believe. Today, you can get any old car to do that.

[@cunning-stunt]

FRIC First seen on the Austin Allegro in 1973 and known as hydrolastic suspension. Each displacer unit contains a rubber spring, and damping is achieved by the displaced fluid passing through rubber valves. The displaced fluid passes to the displacer of the paired wheel, thus providing a dynamic interaction between front and rear wheels. When a front wheel encounters a bump, fluid is transferred to the corresponding rear displacer, then lowers the rear wheel, hence lifting the rear, minimising pitch associated with the bump. Naturally the reverse occurs when it is a rear wheel that encounters a bump. This effect is particularly good on small cars as their shorter wheelbases are more affected by pitching.

[@cunning-stunt]

You're right, the video should have stated the record they broke was the "fastest accelerating EV" under Guiness rules, it's the rule that makes the record. You could go even further and say that acceleration is still acceleration in any direction, so any car crashing into a tree gets more G's, 100-0 is the same as 0-100 to a physicist.

Thank you so much for covering this, I always love when bigger channels showcase what insanely cool stuff Formula Student does.

[@brianhatfield9782]

Very informative, science explained very well, and a small correction in that science: lower pressure doesn't 'suck', you reduce pressure and the surrounding areas of higher pressure fill the void (like releasing the pressure on a spring, it equalizes pressure instantly, creating what appears to be a 'pull' instead of a 'push'). Excellent information and so proud of those students!

[@danielklopp7007]

I spent part of my career making instruments to measure air pressure (at extremely low pressure... what most folks would call vacuum). I always said "vacuums don't suck; surrounding (higher pressure) air pushes". BTW, we made instruments that could accurately measure pressures as low as 0.000,000,000,001 torr (i.e. less than one trillionth of a psi)!

But I'd never stood next to a nitro funny car or dragster. I've just come back from the NHRA Gatornationals, not on the startline, watching from the stands. When the first nitro funny cars came out, I was prepared for the burnout. When they left at the green light, I jumped off the seat, the noise seemed to make the stands shake, let alone my insides. For the next dozen or so green lights with the nitro cars, I knew exactly what was coming, but still I could not stop an involuntary jerk at the total assault on the senses. I finally got used to it and got great photos. Any motor sport lover must go to see drag racing at least once.

sadly hub motors have turned out to be generally kinda rubbish, despite being an idea that's come and gone a few times. Might actually be particularly suited to this one very particular application, however? (Like if you're trying to get a lot of accelerative grip maybe you *want* a bunch of unsprung weight?)

[@arconeagain]

@@tahrey still though. The immediate thought is the ease of being able to control each wheel... apart from it being four wheel. This being another first. Not that it was a car, more of a coach really, a project for a count, I think. Porsche was mucking around with batteries since he was a teen. This also led to the first hybrid, by Ferdinand. So yes, things do come and go.

[@tahrey]

@@arconeagain Well, I can't speak for whatever Porsche was thinking when he set his car up that way. Maybe distributing the weight and also reducing it somewhat by using pancake motors in place of the wheel rims (and brake hubs?) seemed like a good idea, at least in theory. Clearly it didn't catch on and even he didn't feel like persuing it that much further, other than as a testbed for that hybrid. (Who knows whether that idea might have been far more successful if using a regular inboard motor?) As for being able to control each wheel... that's certainly a thing, but you could get that about as easily with inboard, sprung-weight motors that may be of a better shape (as well as easier to wire etc) even if direct drive, and maybe even more responsive with a reduction gear. Just do away with the differential and mount one motor per halfshaft. Or use two or even just one motor, plus two or three active diffs or some other kind of per-wheel power modulation (e.g. the brake-pulsing ESP/TC my car uses to very good effect). One thing with hub drive is that you need to generate a hell of a lot of torque for any kind of launching force, which conventional electric drive achieves with a lower torque motor and gearing. I suppose you also do away with the weight of the halfshafts themselves and the possibility of bending them with the torque coming out of the reduction drive, however?

Cool vid.thx again.....btw...that suspension link system....well my Dad & his team did that to their oval racing stockcar back in late 60s early 70s & won ever race they entered

Great job. Dont forget a Top Fuel dragster does this in half the time. Brute force.

[@cdw3423]

9:52 a front to rear suspension interlink was done LONG before 2011. The first example I know of is from 1948 on a Citroën 2CV. It made for an extremely smooth ride because it dampened pitch acceleration which it seems is what feels the more jarring than vertical or roll acceleration. Julian Edgar made a great video about it on his channel back in August of 2021.

[@jessiebrader2926]

Also 'Hydroelastic' suspension on the Mini in the early sixties.

[@HannyDart]

you dont dampen a car; you dampen plants

[@q.e.d.9112]

@@jessiebrader2926 I seem to remember the Hydrolastic suspension came out on the BMC Morris/Austin 1100 series before they fitted it to the Mini. It was also used on the Maxi and 1800 (cow hips) models, too. I always thought the 1100 and the Maxi were underrated cars. I can remember sitting at a comfortable 85 mph in a Maxi with a trailer and a 14ft dinghy on the back. First mass production car to have 5 gears.

[@jessiebrader2926]

[@Gottenhimfella]

@@q.e.d.9112 You are quite right. I was not quite clear on that point, although I do think I knew it at the time (when I was learning to drive we swapped our Hillman Imp for a Morris 1100). I just checked and Hydrolastic suspension was indeed designed for the car codenamed ADO16, of which the Morris 1100 was the first to be released. It was not retrofitted to the ADO15 (MIni family) until 1964, by which time that line had been in production for half a decade.

The old 1964 Morris 1100 had hydraulic coupling of front to rear suspension called hydrolastic. They handled really well but were under powered.

I initially saw the video thinking it was something related to the inverted project. But at the end I think the fan and the electric motors for each wheel (already decided) just added more power and efficiency to the inverted project. Curious to see how it’s gonna turn out to be :)

[@peetiegonzalez1845]

You just know that's how he ended up researching this stuff. I can't wait to see how it pans out.

[@addictionsucks8848]

My high-school did something like this. We didn't have a ton of funding obviously, but we managed to make a kart that could go 73mph. It's acceleration wasn't great because it was gas, but we were just trying to make a custom kart go fast

[@conflagratus]

A fairly standard race kart will do 120mph. Funding was definitely a problem. These swiss kids had $5,000,000?

[@rustywater3219]

Put the tray more toward the back, because that's what you really want to keep on the ground. Put a spoiler or weights up front, or wheely bars to keep the front down. Hopefully if the tray pivots around the fulcrum (rear wheels) the front of the tray will stay planted. Or maybe 2 trays.

Rocket sled goes brrrrr. Seriously, I'm not sure if this is a good idea. The "ideal" no-rule dragster would probably look something like the sprint missile with some wheels. That thing accelerated at 100 g while going straight up, reaching Mach 10 in 5 seconds. It accelerates so fast that it breaches the sound barrier in its launch tube, and would make everything else including top fuel dragsters look like snails. Of course, the acceleration alone would also kill any potential passengers.

[@NathanMauery]

Top fuel cars are just so far removed from anything else that it's not really a far comparison. Also, I'm fairly sure the record that was broken is a Formula Student specific record, and all the comparisons he did were just comparisons and not meant to lump all the different cars under one record.

[@yannickfeuillet6952]

The record in question is fastest acceleration from 0-100kph of an electric car. This does include all production EVs and prototype EV cars as well, however it has always officially been held by one of a couple of Formula Student teams, as no one from outside that community made any official attempts to beat it. For instance, the previous record of 1.461 seconds was unofficially beaten many times by the McMurtry Speirling. They never tried to get it certified though. With this time though, I don’t think there is any EV capable of accelerating faster at this point in time, officially or not.

[@4rdF1Hunny]

What is this a record of? A top fuel car is still much quicker. 0-60mph in 0.4sec and 0-100mph in 0.9sec

[@robertbuttry5233]

It’s it even quicker than a Top Fuel or Funny Car dragster? I think not

[@hulkgqnissanpatrol6121]

Honestly it's not much of a surprise considering the gearing, rim size and tire size. It's basically an upscaled RC car. 20yo RC cars had the ability to go from 0-160kph in less than 1 second. Scaled up 60 is lost but time is kept...

[@conflagratus]

After modifying my 60 year-old HO scale electric model slot cars, they could do a calculated 600mph. You did, however, have to slow to 300mph to make the corners without flying across the room.

Great job well done. Just so normal people understand how insane this, on a 600 cc racer (street motorcycle) with 120hp driving at 90 kph and adjusting your grip on the throttle can push you from 90kph to 170kph in under a second and that happens faster than you realizing what just happened. And motorcycles and snowmobiles are the fastest accelerating vehicles normal people can buy. This is insanity.
