New era of hybrid cars will run on air

Peugeot-Citroen has unveiled new technology that revolutionises the hybrid powertrain by replacing the electric motor with compressed air. The result is a city car that's potentially capable of 81mpg.

The new technology is due to be officially unveiled at the Geneva Motor show in March but Peugeot-Citroen has given us a sneak peek at its new Hybrid Air concept, the car that uses compressed air as a secondary source of propulsion.
