Citroën to showcase Hybrid Air technology at Geneva
15 February 2013
Citroën will showcase its Hybrid Air system (earlier post) at the upcoming Geneva International Motor Show. The system, developed in partnership with Bosch, combines compressed air and hydraulic power to deliver fuel consumption of less than 3 l/100 km (78 mpg US).
This technology is well-suited to models in the B and C segments as well as LCVs. On the Marque’s stand at the Geneva Motor Show, it will be seen on a Citroën C3 prototype that offers fuel consumption of 2.9 l/100 km (81 mpg US) (69 g of CO2/km). It also cuts fuel consumption and CO2 emissions by 45% in urban driving, compared with an ICE vehicle fitted with the same engine.
The Hybrid Air powertrain combines a PureTech gasoline engine, a compressed air energy storage unit, a hydraulic pump/motor unit and an automatic transmission with an epicyclic gear train. Eighty patents were filed by the PSA Peugeot Citroën Group during the development process.
Three operating modes are available:
- Air power, with zero emissions;
- Gasoline power, using only the combustion engine;
- Combined power, with the combustion engine and hydraulic motor working together.
Because Hybrid Air technology uses no additional batteries, it could be sold at an attractive price on both European and international markets, the company suggests.
