Faster than an F1 car!!
The result is the 919 Hybrid Evo, freed from regulation the tiny V4 engine now throws out 720bhp and the hybrid system now offers up 440bhp that equates to a combined 1160bhp in a car that now weighs just 849kg.
The modifications are more than power and lightness, the car now produces more downforce thanks to a bigger front splitter, huge rear wing and ground effect side skirts.
Porsche was keen to show just how fast their 919 Hybrid Evo can go so they took it to a little know race track called Spa Francorchamps, strapped in tame racing driver Neel Jani and sent him out for a lap or two.
He managed to get the car round in a staggering 1:41.770 which is seven tenths faster than Lewis Hamilton's polo lap from 2017. Jani averaged 153mph and topped out at 223mph
