Default Toyota sets lap record at the Nürburgring Nordschleife

for electric vehicles


Quote:
Toyota Motorsport GmbH (TMG) has set a new lap record for an electric vehicle (EV) at the legendary 20.8km Nürburgring Nordschleife circuit in Germany.
The TMG EV P001, with 100% electric powertrain and Jochen Krumbach at the wheel, set a new lap record of 7mins 47.794secs to beat the previous lap record, which stood at 9mins 1.338secs, by a very substantial margin.
Using two electric motors, the TMG electric powertrain has a top speed of 260km/h which combined with 800Nm of torque to achieve impressive speeds on the extremely challenging Nordschleife track, which includes significant elevation changes and lengthy flat-out sections.

cool video. You can really apreciate the tire noise without a loud engine. The car seems to understeer quite a bit but I suspect that is a bit of an allusion caused by the lack of engine noise. Im sure the cars range is pretty much exactly 1 lap. The site indicates road legal tires, but I am not sure what that means for germany.

Two things I'd like to see would be mph for the entire run and voltage drop. Its also direct drive, different from some of the other prototype electrics that have gear boxes, I'd love to get a look at their motor/controller and battery set up!

Cool stuff though.

Now make something like that in a production model that can do it in a similar time, costs around $40k and can be recharged in around 4 minutes and I'm sold.

Are you even serious? What gas cars around $40k do <7:50, let alone EVs?

Well, they certainly sound like an street-legal r-comp, compared to a full slick. My guess is something like a Corsa or the like.

Definitely understeers. I think you'll find a lot, of not most race cars suffer from low-speed understeer to make them manageable in fast sweepers. Although that car looked particularly brutal...it's a good way to make sure it stays out of the wall.

Upon a second look, it was plowing at any speed. "Boring" to drive, comparatively I'm sure.

Yeh it was the high speed understeer that suprised me more than the low speed. You could see/here the car not responding to further steering lock even in the sweepers. I guess there wasnt much areo.

The sound of the wind rushing and that electric motor revving is fairly appealing to my ears. When I say "fairly" I really mean "really."

p.s. how do get to be a nurburgring test driver? I would trade at least one body part and one relative for such a career. Maybe even another body part if it came with the German Rosetta Stone.

Did you even read my post? Notice I said similar, not the exact same. Why not something in low 8 minute range, ~8:05? Of course you glanced over the most absurd requirement, recharged in 4 minutes. It was the lap time that made you scoff, not the ridiculous recharge time. You are at least consistent I suppose.

They used a Tesla to record tire sounds for some video game b/c of that. I forget the details, but it makes a huge difference.

20 minute high voltage DC quick chargers exist. It's not inconceivable that one hopped up (transformered up? ) for racing use might improve on that by an order of magnitude.

If I can recharge my car by the time I manage to buy a drink from the clerk at the gas station on my road trip then it's a win. Toyota just showed they can solve one of my gripes with EV's, now to combine it with the solutions to the other two: reasonable price and recharge time.

it's a Radical RS - the whole car is aero...

My guess the the oversteer is due to the entry speeds and the TQ of the electric motors.

Understeer could be caused by derptastic battery placement.


Doubtful on a car meant to lap the ring, but who knows. It's only Toyota.

There was no oversteer. The car plowed, seemingly badly, in corners of all speeds.
