Petrol v diesel: what can we expect at Le Mans?

Prodrive boss David Richards recently spoke out about the inequalities between the diesels and petrol-powered cars at Le Mans, claiming the disparity effectively puts his Aston Martin team firmly among the 'best of the rest'.

The issue has been one that the Le Mans organisers, the ACO, have tried to address each year and once again the diesels of Audi and Peugeot have had their power reduced in an effort to give the petrol cars greater competitiveness.

But is it really just a question of reigning in the diesels or is there a greater debate to be had?
