The “green” race cars participating in this year’s Le Mans got together for a good old fashioned photo-op. Moving from left to right we start with the Nissan Deltawing. It’s half the weight and aerodynamic drag of a normal race car so it only needs half the power and fuel. The blue and white car is the Toyota TS030 which ended up not competing in Le Mans due to a heavy crash in testing. It’s powered by a gasoline V8 on the rear axle and electric motors on the front. The silver and red car behind the Toyota is the Audi E-tron Quattro. It’s rear axle is powered by a diesel V8 with electric motors powering the front axle. The interesting aspect of the Audi is that it uses the electromagnetic flywheel energy storage system that’s been campaigned on the Porsche 911 GT3 RS Hybrid. The black and orange car on the end is the hydrogen powered GreenGT H2.
