I am surprised with the 911's lap time - given it's pretty good power-to-weight and, according to the reviewers, brilliant handling, it seems too slow against other cars. What gives? Tires, driving style, track favoring high horsepower? Or is it really that slow (of course only in comparison to other crazy-quick cars)?
Another thing I do not understand is the huge difference in slip angles on figure 8 among different cars. Why is that and what does it mean?
