Citroën will unveil its all-new Hybrid Air technology at the Geneva Motor Show. Based on a petrol engine and hydraulic components (engine and pump) but no battery, Hybrid Air technology combines ground-breaking performance (savings of 45% in city driving compared with a similar petrol engine, less than 3 l/100 km, 69g CO2/km) with maximum accessibility (mechanical components, no power supply required, vehicle space maintained).
