I think it's design rocks, but it wasn't allowed to run in the actual le Mans race, was it? It participated for show and testing if i don't remember totally wrong.

No it did run and ended up crashing with a Toyota https://www.youtube.com/watch?v=FJAiZVuC3YI

It didn't fit any normal classes so they entered it in a experimental class.

That's what I thought at first, but it works on 3 levels:
1:the wheels are a long way out in front and thus have good leverage
2:the weight is mostly in the back, which is something race car builders strive for
3: the braking is mostly done from the rear wheels, drastically improving braking stability


But... Umm.. That's wrong. :|
1:Long wheel base = bad for turning. Think of the MX5. A shorter wheelbase means quicker turn-in as there's less circumference to the turning circle.
2:Not 100% on this myself, but I'm pretty sure that racing cars are built for as close to a 50/50 weight distribution as possible. It aids with grip and handling.
3:Braking done from the rear wheels isn't stable at all. What happens when you pull the handbrake in your car? It slides all over the place! :lol: This isn't a bad thing, but I'd bet most racing drivers with the exception of drifters would disagree with me!

1: You're right, but this car uses torque vectoring, it means the rear wheels are doing great part of the job of turning the car. Put more torque on the external wheel and the car will turn.
2: Yeah you're right again, but this applies to "normal" cars, where rear wheels push the car, front wheels turn the car. But the DW is not a conventional design, and can't be annalyzed in a so simple manner.
3: Sorry but you're wrong in this one, pal. With most of the weight on the back, the rear wheels will have sufficient grip to do most of the braking, as opposed to normal cars, where the weight is shifted to the front, and the rear wheels get less grip (remember: friction = mu*N).

It looks like something you would see attempting a speed record ?

I think it might actually fly.. :lol:

I have been less than 25 feet from that car at Le Mans 24 hours last year yes I was there and I saw it race...the clever thing about it was the bodywork was designed to be the wing itself
