(VIDEO) PSA presents a new breed of hybrid, gasoline / compressed-air


Yesterday PSA unveiled a new type of hybrid car that runs with an internal combustion engine combined with a compressed air engine. A revolution!

Air-hybrid vehicles will be produced on Peugeot and Citroën assembly lines from 2016. This has been announced yesterday by the manufacturer during a press conference in its test center in Velizy, Paris region. The technology developed is promising, in terms of consumption and CO2 emissions reductions.


In combined cycle, a car like a Citroën C3 will consume 2.9 l per 100kms and emissions of 69 g/km allowing it to get a 550 € bonus in France for instance. But it is in the city that the improvements are the most impressive range would be increased by 90% compared to a combustion engine vehicle with similar power.

How does the technology works?

Unlike a hybrid-electric car, gasoline-air uses no batteries to store energy when it regenerates during the braking phases, it stores energy by pressurizing air in two cylinders.

The movement of the shaft during the slowing down and braking phase is used to rotate a hydraulic pump.
