Doesn't say how much it will cost, though...

very very tidy!!

Not a bad looking car

I can't imagine how they manage to dump so much energy into the car in a 10 minute recharge...

I call bull on the 0-60 in 2.5s figure, and I'm an engineer.

Since the maximum forward force that can be maintained is limited by the frictional forces between car and road, this figure is essentially capped at F = m*g*u, given your maximum forward acceleration, F=m*a, this cancels down to acceleration=g*u
Given best case scenario where coefficient of friction is 1 (which is unlikely), your maximum acceleration is 9.8 ms^-2, which give a best case 0-60 in 2.7s

However, this neglects downforce, but even if you were driving a wedge of a car, you still wouldn't be able to generate enough downforce to achieve 0-60 in 2.5s, especially since your coefficient of friction is more like 0.7 with any road-legal tyres.

Pro fuel dragsters manage 0-60 in <1sec and do the quarter mile in around 4sec.

By his theory cars wouldn't be able to do >1g in corners. If I read it correctly.

I think that confirms that electric cars are the way forward.

the bugatti veyrons 2.5s to 60 though, isnt it??

why cant all electric cars look as good as that?

It is quite an old-fashioned design - all curves and no sharp angles - but all the better for that, IMHO.

I'll wait for the Locost 7 version. But I'll also wait for the one guy per month who electrocutes himself making it.

Those cars need a wind up handle like the little rechargeable flashlights (torches for you), so the passenger has something to do. He can charge the car while you drive.

true or not?

What that guy's missed is that max acceleration is not G. That's just acceleration due to gravity. Although, I do doubt that it can do 0-60 in 2.5, AND 208 mph, AND have a 150-200 mile range. And there is no way it'll do a fully flat to fully charged recharge in 10 minutes. Not on a 220V system anyway.
Although I would like more details on the Charge on the Run system. It seems to be regen braking, but that can only do so much.

I know that top fuel dragster are exceeding those 0-60 times by a long way - the only explanation I have, without googling, is that hte coefficient of friction must be more than one - wide slicks that are heated up prior to the run to make them very sticky .

i'll take 2 please one for me and the other one just so we can test all these radical theories !

that is easy for you to say but why?

I thnk of it like this.

Imagine a large wardrobe and you are sprinter using it as starting blocks.

The friction will determine how much force you can get going forwards. If it was solidly mounted to the gournd = infinite friction then you go a log quicker than if it was on ice.

Just what we need - an eco-friendly 200mph supercar - way to save the planet...........not
Surely a better use of this technology would be an electric car with normal performance that cost's no more than a petrol/diesel car ?

10 minutes for a full charge? Not sure how that works. Even if the batteries can take it without killing their life, would a 13 amp socket be enough? Doubt it.

Reminds me of the hypercapacitor that eestor have been promising for ages (and continually delaying). If that ever comes about it'll be the coming of age of electric cars. Seems to be a race between that and hydrogen.
