It was great to shake the hands (and one wanking claw) of all, new and familiar!
I must say that the TDI was very interesting to see, but certainly not inspiring as a fan. From a fan's perspective, motoracing is massively about atmosphere. Visual AND audible - and I guess the smell and feeling of the event too - racing fuel and the chest thump of screaming and rumbling engines alike. The Audi really was as close to an electric sounding car as it could be right now. Nothing exciting, nothing memorable, and a field of them (the way it's going I fear - with Pug ramping-up for their LM effort - and God knows who else to follow) would be a very dull to spectate.
Le Mans and other events are about atmosphere - and given that so many of us sit in a field and get sh*t faced for large periods of the event bathed in the wails and growls from the Mulsanne, Pit Straight and Esses to name a few, it would be pretty odd sitting there with no sound at all - which is essentially what a lot of future diesels would bring to the event.
Motoracing has evolved and should evolve - but would you go to an electric car race?
