Hi,
because this fact, may be it can be interesting the words Dr. Ulrich about Formula 1 and endurance:
'Let me show you how – at Le Mans, one of our cars will cover 325 miles more than an F1 car will cover in an entire season, our average speed including pits stops will be 20mph higher than an F1 car and we will use 42% less fuel. '
Although this position is not new, you can read here about the reasons why Audi says NO to Formula 1.
Sure, I don't want to start a battle between followers of either endurance or formula 1, because I like both (beyond Fernando Alonso), although I do prefer endurance races. May be because I can shot a lot of photos in these races, without being highly stressed .
