Hybrid vehicles are pretty popular these days and the trend will continue. Peugeot has taken the hybrid idea and taken it into a different direction with their HYbrid Air technology. The Peugeot 208 HYbrid Air 2L is capable of returning a fuel economy of 2L/100km (117mpg US / 141mpg UK). Those are some impressive numbers!
HYbrid Air works just like your standard hybrid system but instead of having a battery pack as a secondary power source, it uses compressed air which is stored in a tank located in the back of the vehicle. The system uses a hydraulics to manage between the engine and the compressed air. The air tank replenishes when you apply the brakes (just like regenerative braking systems) and it takes a total of 10 seconds to fill up. The Peugeot 208 HYbrid Air features a 1.2-liter engine producing 82 horsepower but not details on the combined power. The vehicle weighs in at only 1,896 pounds and is set to make its debut at the Paris Motor Show.
