Audi looked like a wounded giant at the end of last year's World Endurance Championship. It might have triumphed in the Le Mans 24 Hours and kept the championship open to the penultimate round in Bahrain, but it was outgunned on the Tilkedromes that made up much of the second leg of the series.
Now it is back with a major update of its R18 e-tron quattro and a real confidence that it will be in the fight for the WEC titles as well as a 14th victory in the race that really matters in France on the middle weekend of June.
Audi's reaction to a season in which it was only truly competitive at three of the eight WEC race - the two it won, at Le Mans and Austin, and the season opener at Silverstone - with a root and branch overhaul of the R18. The new shape of the car indicates a major aerodynamic overhaul, while the target of moving up one megajoule class on hybrid power has been achieved.
