The current world record speed for the fastest production car was set by the SSC Ultimate Aero that topped at 255.83 mph which is 411.71 km/h. Recently the 9FF engineers tried to beat that with their modified GT9 but couldn’t do it. They only managed to make it run at 409 km/h at a track in Papenburg on 10th April.
9FF’s GT9 was based on the Porsche 911 GT3, but lower and longer. The interesting part is that the car has the engine in the middle (not the rear) for better weight distribution... the beast outputs 987 bhp from a 4L flax six twin turbo and a six-speed transmission. The GT9 however, is not as fast as the Veyron : 0 - 60 mph in 4.2 seconds.
