If the compressor station can use the heat for district heating or process heat, and the car is covered with heat exchangers to re-warm the air between multiple expansion stages, you could wind up with the same sort of over-unity benefits as a heat pump.

I'm sure I've ranted here before, against the dangers of a "fuel" that can give up all its energy instantly, without mixing with air first. The french Air Car is a stock scam, IMHO. A magazine got to test one, and the range was 39km, not the advertised 200.
