There are plenty of cars that cracked the 1000bhp-per-tonne mark entire decades before the AM-RB 001.

The only problem was that you had to be in Formula 1 to get to drive one. So what does it feel like for each kilogramme of the car you’re driving to have it’s own, personal horsepower in order to get it up in the morning? As someone who tests old racing cars from time to time, I am in the blessed position of being able to tell you. 

Most recently I drove a 1970 March 701 with a brand new Ford-Cosworth DFV in the back. That's a probably slightly better than 500bhp motor in a 500kg car, and while the maths does inevitably change once you add in the large motoring journalist behind the wheel, this should not affect the essential thrust – no pun intended – of what follows.

When you light it up, your first feelings are not those of excitement, exhilaration or even euphoria. They are of fear. If you can climb cold into a 1000bhp-per-tonne car and deploy it all in a low gear without some reptilian flight instinct deep in your cerebral cortex forcing you to lift almost immediately, you are a better and braver man or woman than I.
