This could be interesting but I did hear they were scrapping the plans!
Reports claim that development of the Hybrid Air system by PSA Peugeot Citroen has been put on hold after the departure of the programme’s chief and an unsuccessful search to find an automotive partner with whom to share costs with.
Ahh I see. It's still good to see car companies such as Peugeot looking into more sustainable ways to power the car. Especially when it comes to small city cars that are also very fuel efficient and reliable for the most part.
