Diesel propulsion isn't anything new in Le Mans-class endurance racing. Hybrids are still a rarity, but even when Toyota returns to Le Mans with a hybrid LMP1 next year, it won't be alone. That's because Peugeot is preparing to chart new territory with the 908 Hybrid4.
Some concept cars are purely for show, but some are built to go. GM Europe took the latter a step further by putting their striking and exciting Chevrolet WTCC Ultra concept to the test on the track. The concept race car made its debut at the Paris Motor Show and is scheduled to make an appearance at the Beijing show later this month. So in between, the Chevy boys took the opportunity to put the car through the paces at Estoril in Portugal.
