The 24 Hours of Le Mans (check after the break for details on how to watch, for free) hasn’t even started yet and already history has been made. During warmups, Nissan wheeled its ZEOD RC prototype race car around the 8.47-mile Circuit de la Sarthe track running only on battery power, a first. ZEOD stands for “Zero Emissions On Demand” and the car squeezes a 1.5-liter three cylinder engine that produces 400hp plus two electric motors and the regenerative breaking of a Leaf RC into the frame similar to the older DeltaWing prototype racer. Did we mention that it has no rear-view mirrors? Ray Harroun would be appalled.
