This year marks 21 years since the mighty McLaren F1 was launched. That car was, and remains, a landmark car. It was the world's fastest production car as well as one of the most expensive.

And now McLaren has launched a pretender to that crown - the McLaren P1.

In developing both models, McLaren used all the cutting edge technology and materials available to it in the pursuit of making their cars the best they could be. But 21 years separates them. Technology moves on. And now we lay bare the numbers that define both cars.

Autocar has produced digital books on the McLaren P1 hypercar as well as the F1 and 12C supercars.
