Five-seat concept car runs on air

An engineer has promised that within a year he will start selling a car that runs on compressed air, producing no emissions at all in town.

The OneCAT will be a five-seater with a glass fibre body, weighing just 350kg and could cost just over

It will be driven by compressed air stored in carbon-fibre tanks built into the chassis.

The tanks can be filled with air from a compressor in just three minutes – much quicker than a battery car.
