It's true that very few supercars can match the awesomeness of the McLaren P1, but when it comes to track hooning, there's more to a car than just brute power and torque. Take the Bugatti Veyron->ke1112 for instance. It comes with more than 1,000 horsepower on tap, which makes it one of the most powerful supercars in production. Is it a proper track car? Not quite. In fact, we don't see it taking laps very often, which says a lot about its racing capabilities. Race it against the Caterham 620R and you're bound to lose.

Which brings us to the video below, in which an utterly powerful McLaren P1 is chased by an ultra-light BAC Mono on the Silverstone track. Comparing the P1's 903 horsepower with the BAC Mono's 285 ponies, it's easy to say the latter is no match for the McLaren. However, bring the curb weight into the equation and the 600-horsepower gap reduces dramatically. That's because the BAC Mono weighs in at only 1,190 pounds, which means 479 horses per tonne. On the other hand, the McLaren tips the scales at 3,280 pounds, resulting into a horsepower per tonne rating of 551 ponies. Not that big of a difference, huh?

This pretty much explains why the BAC Mono in the video above manages to catch up and overtake the McLaren P1, although the supercar is obviously faster in a straight line. The lightweight sports car is superior at entering and exiting corners, which proves once again you don't need nearly 1,000 horsepower to be fast on the track.
