Another apples to oranges thread? Ok I´ll bite
With equal power/weight ratio cars are faster, period, but for a car to have equal power/weight ratio you need to spend at least 10x the money of the bike. But the thread title is High Perfomance cars, so that´s it
Cars corner considerably faster, or so much faster that they are on a different league (with downforce), as you can notice when comparing F1 vs MotoGP and see F1 laptimes are more than 20 seconds per lap faster. As a reference, difference between F1 and GP2 is a half of that, what means even GP2, wich is spec series, is much much faster than MotoGP, around 10 seconds per lap
OTOH bikes can do lines with higher radius wich depending on the corner might be a very big advantage, for example what for a car is a chicane (with short corners) for a bike might be almost straight, so anyone with a bias towards any of them can do a comparison where its favourite will win.
Also, road bikes are much much closer in perfomance to top level bikes (MotoGP) than road cars are to top level cars (F1). The comparisons we usually see are always with a bike wich is much higher in the perfomance scale than the car he´s competing with, or there would be no debate at all, and that does not provide clicks wich is the intention of any article/comparison
edit: I love bikes, I´ve been an MX racer (amateur) and I own a street bike, but reality is what it is. About the coment stating if the rider balls are big enough he will beat the car, I say the opposite, have any of you raced against a high perfomance car with a driver who really pushed the car to its limits?
