This will murder anything on the road with two or four wheels.
I love the P1 but even now, cars like it and the Koenigsegg and the new Porsche 918 are just knocking on the door of what a literbike will do, both in acceleration and on the track. I used to think that cars had the edge in lap times when curves are included, but a detailed discussion on vwvortex a few months ago changed my mind. The motorcycle record on the Nurburgring is 7m10s, which is faster than almost every car on the list except the 918. If you look at the lap times of your average motorcycle organization on tracks that also have car times, the motorcycle times will on average be faster - that's with regular humans not professional racers. On tracks that professional races occur with both motorcycles and cars, like Laguna Seca, the motorcycle times are usually faster than all but the most aerodynamic cars like F1 or closed cockpit prototypes (F1 is simply leaps and bounds faster than
anything on a road course, i'd never argue that). Funny thing is, even fully race prepped motorcycles are not
that much faster than their stock counterparts. At the Isle of Man TT last year, John McGuinness set the records for both the superstock and outright categories. The difference was only 4 seconds, over a 37 mile course. I think the only modifications that can be made to the superstock bikes are tires, minor suspension and brakes, and obvious safety mods. But 4 seconds over 37 miles is almost nothing. Insane what a stock bike can do nowadays.
