I OWN THIS CAR NOW CALL FOR QUESTIONS 5412793111 ITS REAL !!!! THE FASTEST M COUPE IN THE WORLD NO COMPETITION BUT LOOKING...THIS VIDEO IS NOT FULL THROTTLE AND IS NOT RUNNING FULL POWER SETTING ..

It can't be 700. My guess would be about 550-600. There's a video on here of a 30psi Euro 3.2 (stock power is 321), and they claim it's 1000hp, but the website it's from doesn't even show a dyno, so it's plain overrated turbo bimmers..but this sure is fast!

no way 700 hp .... bout 500 to 550... that car is light and if it was puttin out 700 whp than may god have mercy on the drivers soul...

10 sec car with more grip and faster shifting, no doubt about that an, more think this thing is about 600 bhp

there is no way thats 700rwhp

i cnt hear crap but it did look pretty fast

Holy crap!!! I want it.

Wowie zowie... that's fast!!!
