PSA’s Hybrid Air technology is similar to current battery electric hybrid vehicles, such as the Toyota Prius, but it uses compressed air for energy storage rather than batteries. A hydraulic pump/motor unit recovers energy generated by the ICE and from braking and deceleration, storing it in a compressed air energy storage unit.
PSA says for city driving, its Hybrid Air system provides fuel savings of 45 percent and increases a vehicle’s range by 90 percent compared to conventional engines with the same power rating.
In standard body styles, such as the Citroen C3 and Peugeot 208, the company says the system achieves certified fuel consumption (combined cycle) figures of 2.9 l/100 km...

This technology has been in development for over a decade and is technologically well in hand. The decision to use compressed air as an assist to a normal gasoline motor eliminates concerns of short range. The fact that a major manufacturer gets in on the game means we will soon see some of those cars on the road.
"...with a few exceptions, such as Volvo’s Air Motion Concept, major automotive manufacturers have generally shied away from such technology.
PSA Peugeot Citroen is bucking this trend with its “Hybrid Air” powertrain that addresses the limited range of compressed air energy storage technology by combining it with a gasoline powered internal combustion engine (ICE).
The company plans to have Hybrid Air powered vehicles on the road by 2016."
