That’s a pretty impressive claim for a car, no? Well the BBC has a report on such vehicle. The premise is reasonably simple – filled a tank with compressed air, and then use that pressure to power the engine. It is more of a hybrid car TBH, as it can also use more traditional liquid based fuels to increase its range, and performance. Check out the video for a demonstration. Obviously it will need to pass safety tests, and I’d be particularly interested to find out how well the carbon fibre tank for storing the compressed air will survive side impacts etc., but that said, it certainly looks like a promising direction for the motor industry to be facing.
