Air-powered hybrid car unveiled.
Peugeot Citroen have shown off a hybrid car which can run on petrol or compressed air, or a combination of both.
The ‘Hybrid Air’ system uses a petrol engine for travelling at ‘cruising’ speeds, where the makers say petrol is still the most efficient power source. At slower speeds or when the vehicle needs extra power to climb a hill, the car uses a combination of compressed air and petrol. At slower speeds below 43mph the car runs solely on compressed air until the supply runs out.
The air tanks are refilled during all modes of driving, by re-using energy normally lost during slowing down and braking, instead using that energy to run an air compressor. The makers claim an average fuel saving of 45 percent, and when driving solely around cities at slower speeds that figure could rise to 80 percent.
The car is expected to be available by 2016.
