The World Endurance Championship resumed after the Le Mans 24 Hours at the Nurburgring last weekend and Porsche won. It might look like a case of deja vu, but the result is where the similarities with last season end.
Porsche dominated at the 'Ring last August, setting the tone for the rest of the season - the 919 Hybrid would remain unbeaten over the remaining WEC rounds. On the evidence of a thrilling event in which Audi had the pace to challenge its rival at different times of the race, that's unlikely to happen this time around.
The arrival of a high-downforce package of aerodynamics at this stage of the season in 2015 allowed Porsche to fully exploit the key technical advantage it enjoyed over its rivals. The 919 was racing in the top eight-megajoule hybrid sub-class, whereas Audi and Toyota were respectively running in the 4MJ and 6MJ divisions.
