“Five years is a long deal for a bloke who’s 36 years old.”
Endurance racing drivers tend to carry on well into their 40′s while still remaining competitive. Allan McNish is 43 and Tom Kristensen is 45 to mention two. I don’t think that, if they have signed him for 5 years, that it is a foolish decision by Porsche. Webber is still quick, he’s into his 12th season at the highest level of motorsport and he’s done Le Mans twice already. He’s a great choice to lead their squad I think. If Webber does sign for Porsche, manages to compete at a good level and enjoys the atmosphere and challenge of WEC, I don’t see why he wouldn’t stay in the series for 5 years.
