I saw that car on a 5 mile straight away (its a straight road I think in Germany, if you stand at one point u cant see the end because the curvature of the Earth kicks in ) going 700 KMPH. For making it go fast you have to put a key that turns on the "fast mode" and the car goes lower and the spoiler goes lower...its crazy!
since they didn't say it in the video i shall do the math for you. the car hit 407kmph. that translates to 252.898078mph. in a street car that is awsome. no i'm not that smart but my phone is. it has a smart converter on it....lol. i sucked at math...lol
yeah they have another video of one on a road coarse. if you listen to the car as they are going around the coarse it isn't even begining to move by the time they have to slow down for the next turn again. its an awsome car but how many people are actually going to be able to run it up to its full potential.
there is but they don't have the gearing like the bugatti. plus i don't see too many of them going wide open throttle like that does for as long as it is. not unless it is a purpose built car like the salt flat cars are.
