I remember reading all about audi's group B history before. Apparently the first group B quattro was about 350bhp and then they built a 600bhp engine or there abouts but they went up to an engine with 1000+bhp but according to stig blomqvist it was too difficult to control. Which honestly suprised me. I mean trying to drive 1000bhp of monster car on gravel through a forest you would have thought that would be easy to do
