Citroen C3 Hybrid Air concept cuts emissions by 45%

PSA Peugeot-Citroen’s new breakthrough hybrid air technology revealed just last month (see story) is to make its debut in Geneva next month, attached to a Citroen C3.

Developed in association with Bosch, the new hybrid system works by using compressed air for energy storage rather than a battery, making it a lightweight and more affordable approach to hybridisation.

Debuting the Citroen C3 Hybrid Air concept at the Swiss show next month, the new car will show how the new technology can help it deliver economy of 97mpg on a combined cycle and emit as little as 69g/km CO2. In urban driving, fuel consumption and CO2 are reduced by nearly half (45%) compared with a vehicle solely fitted with the same internal combustion engine.

According to the carmaker, the Hybrid Air system is also unaffected by adverse weather or driving conditions, has less on an environmental impact than batteries and does not impact on interior space.

The Hybrid Air system combines a compressed air energy storage unit, a hydraulic pump/motor unit and an automatic transmission with an epicyclic geartrain and couples it with a PureTech petrol engine. Eighty patents were filed by the PSA Peugeot Citroën Group during the development process.

The car works with three operating modes; Air power, with zero emissions, petrol power only and combined power, where the The Peugeot-Citroen Hybrid Air systemcombustion engine and hydraulic motor working together. 

Up to 43mph, Air Mode works in the same way as the EV mode does in traditional hybrid cars, making it possible to travel without any dirty tailpipe emissions. Depending on traffic, this mode can be active between 60 and 80 per cent of urban driving time.

Citroen reckon the system would be easily adaptable for both passenger cars and LCVs, and is particularly efficient on B & C segment models like the C3. 

The concept will be unveiled on March 5, 2013 on the opening press day of the Geneva Motor Show. The Geneva Motor Show will open to the public between 7-17 March, 2013.
