A few weeks ago I penned a feature for Autosport magazine about the fastest five F1 cars in terms of the leaps they made over what had gone before. The arbiter was something called the Pomeroy Index, invented many decades ago by Laurence Pomeroy Jr as a way of comparing lap time capabilities of cars that never raced against each other.
He took the lap speed capability of the first winning grand prix car - the 1906 Renault - as an index figure of 100. For the purposes of the feature we updated the index up to 2004 where the Ferrari F2004 had a calculated index of 234.7, meaning it could theoretically get around any given track 2.347 times faster than Ferenc Szisz's old Renault.
The beauty of the index is that it can give you a figure for pretty much any car you choose. So I've been having what comedian Rob Brydon might call 'a bit of fun' with it. In honour of Hungarian Szisz, the winner of the very first grand prix, I based a grid around the Hungaroring.
So, taking Michael Schumacher's pole time of last year as a base, here is how the fastest cars of each preceding decade would theoretically line up behind it.
