The car you see here isn't Batman's latest ride, it's called the Nissan DeltaWing, and it looks very strange. The car is described as part road racer and part salt flat racer it is designed to be more aerodynamic than other cars on the grid and to use half the fuel the other vehicles use. Interestingly, the car isn't a pure flight of fantasy research project either. It will be coming to the 24 hours of LeMans. Fuel economy is a huge deal in endurance racing and if the car delivers on its promise it could be very competitive indeed.
