Air Pneumatic Cylinders

Is it possible to make a car run with compressed air by using a pneumatic drill instead of the engine?

to replace engine with a pneumatic drill which runs on compressed air.and the air stored in a cylinder at high pressure

Many large diesel engines have pneumatic starters. They create a great deal of torque for a very short amount of time and use a lot of compressed air doing it – so much so that once the diesel engine is fired up, the driver often has to wait for the air pressure to build back up before he can drive (the brakes are also pneumatic).
Air compressors are typically very inefficient and pneumatic motors add even more inefficiency to the whole package. A great deal of pressure would be needed to produce the torque required to power a vehicle and this pressure would have to be available in large quantities (CFM per minute). This would require a large, multi-stage compressor – probably larger than the typical engine it would replace – and that doesn’t even include another engine necessary to power the compressor!
That being said – your premise is correct, it is indeed possible to power a car with compressed air – just not practical.
