Running on fresh air
In an attempt to cut fuel consumption to as low as 2L/100km, Peugeot has turned away from electric hybrid power plants and has moved to air power.
Its HYbrid Air technology is a key step towards this objective, and Peugeot is presenting the concept at the Geneva Motor Show this month in its 2008 crossover.
The new drive train follows on ground-breaking work over the past two decades by Frenchman Guy Negre and his MDI company in attempting to bring a pure air car, and later a petrol-air hybrid, to the market.
The air technology, uses energy recovered during braking and deceleration, much like a petrol hybrid, but converted into compressed air stored in a high pressure accumulator (cylinder) in the centre tunnel, with a low pressure accumulator at the rear axle, and an engine/pump assembly fitted to the transmission.
The car produces zero emissions when running in air mode, and has the advantage that it does not require the rare earth metals being currently eaten up from the world’s reserves for the production of the latest generation of electric motors.
It also doesn’t require heavy and expensive batteries, and nor does it present a fire risk in the event of an accident.
The air hybrid system also takes up less space and weighs much less than an electric hybrid system, and nd it allows for three modes; Air (equivalent to a pure ure electric vehicle), Petrol and Combined.
Peugeot says it will have the vehicle on the market in n two years.
The HYbrid Air 2008 also uses Peugeot’s latest latest generation three-cylinder petrol engines, also to be shown at Geneva, among the most economical around.
Now that’s a clever use of technology to save on fuel AND keep the air clean!
