Volvo's 'Blowing in the Wind' Concept

Lighter than a Formula One racing car tipping the scales at under 1,000lbs, the Volvo Air Motion Concept has been designed like a clam shell and sculptured from ultra light carbon fibre.
Minimising weight and complexity, while maximising driving enjoyment, is the philosophy behind this vehicle. Thousands fewer components are employed than in a traditional car thanks to the powerful yet simple compressed air motors that replace a heavy internal combustion engine. The motors cool down under load rather than heat up, thus removing the need for heavy cooling systems. An integrated approach to designing the chassis, interior and suspension also contributes significantly.
To compress the air needed for the centrally mounted air tank, Air Replenishment Sites are used. Powered by air turbines floating 1,000ft in the air they harness the power of the wind and convert it to electricity to provide the compression.
