2.15 seconds: Students break 0-100 acceleration world record

Students break 0-100 acceleration world record

The DUT Racing team from TU Delft, The Netherlands, has broken the world record for acceleration from 0 to 100 km/h for electric cars. The previous record stood at 2.68 seconds, but as of today the record is now held by the TU Delft students with 2.15 seconds. 'We thought that under these conditions we'd be happy with 2.30, but we really didn't expect 2.15,' says team manager Tim de Moree.

The students used their self-built from 2012, the DUT12: a compact racing car with full four-wheel drive, weighing only 145 kg. The car was built for the Formula Student competition and the students won the unofficial World Championship with it at Hockenheim.

As light as possible

Every effort was made to break the acceleration record. Gihin Mok, one of the students responsible for the car, explains: 'We made the car a little lighter where possible, but the major difference lies in the electric motors. In the Formula Student competition, they were only allowed to produce 114 horsepower. The motors we used now are actually much more powerful, which means we had to limit them during the race. Now we used the . That totals 135 horsepower, about 33 horsepower per motor and almost one horsepower for each kilogram of weight.'

A home-made oven, made from an old oil barrel, ensured that the tyres were heated at the start. Even the racing driver was changed to achieve the fastest possible acceleration: Marly Kuijpers, 24, is the lightest member of the DUT Racing team. During the official competition, she had already achieved 2.50 seconds for acceleration from 0 to 100 km/h. Today, she has set her own and the world's fastest time. Talking about the feeling during the drive, Marly says: 'It feels like a , that part when you just drop over the edge.'

That's a nasty bit of acceleration. How did they get the tires not to slip? Spray them with superglue?
I know they heated the tires before the start (as they do in F1 racing), but the traction you gain by this is limited.
Can't wait to see when the first full blown Formula E race will get under way in 2014. That should prove interesting.

That's an impressive time, even for a fueled engine. Congratulations!
And the driver was a girl...

It is, however, this car does weigh 10x less than the cars capable of these speeds.

Antialias - You can get these accelerations on motorbikes (I know because I ride one and get similar figures) and that's more often than not 1 wheel, maybe 2 lol.

4 wheels not a problem. They make amazing tyres these days. I am sure they used very nice racing tarmac too...

Cool someones voted me 1.5 already

Proof other cars are 10x heavier than this 145kg machine with similar acceleration, the bugatti veyron, weighing in at 1888kg.

Motorbike accelerations, just google Yamaha R1.

Traction would be legally required for both these machines to be made public.

So please, if you have the balls, explain how I am wrong in any 3 of my comments made previously?

Well, my last motorbike was a chopper. I don't think I got that kind of acceleration out of it.

Frankly, that kind of acceleration would scare the Bejeezus out of me.
