Unlike an ordinary car, the engine on the DeltaWing is behind the driver right at the back. This makes the car easier to steer, while its light weight and shape make it far more efficient.
Although the car will be driven at the Le Mans 24-hour race, it won't be competing officially. Nissan just want to showcase what the future could look like for motorsport.
The car on show in London is an exact replica of the one currently being tested in the US. It uses a special engine and its unique shape means it cuts out half the air resistance that would usually slow down a conventional racing car.
Nissan have revealed their latest motor, and it looks like Batman might drive it! DeltaWing's an experimental race car that will run at the 2012 Le Mans 24-hour race. Ben Bowlby on the left helped design it.
