Peugeot-Citroen’s unique hybrid-air technology, currently being showcased at the Geneva Motor Show, will be in production by 2016, using the group's new EMP2 platform.
That new platform makes its debut on the new Citroen Picasso, while the hybrid-air tech itself is being demonstrated attached to a Peugeot 2008 and a Citroen C3.
Although the idea of using compressed air to power cars dates back to the late 1950s, the challenge is to prepare components that haven't previously been used in mass production in the car industry, Dr Karim Mokaddem, director of the hybrid-air project tells Headlineauto.co.uk.
"We are working with Bosch to industrialise the process," he said.
Work on the project started only two years ago and first prototypes were very efficient in city driving but less efficient at higher speeds.
Now on its fourth generation, PSA Peugeot Citroen is promising a 45 per cent fuel reduction over the equivalent petrol engine and CO2 emissions down to 69g/km.
The other bonus is that the technology is more affordable at "about half the cost of traditional hybrids," he said.
"The technology and components are not new - what's new is the way we have put it together."
