This has been looked at by other manufacturers including BMW, and everyone involved has found the same thing - that it takes much more energy to compress the air than you ever get back from it. It's the same reason that hydrogen doesn't currently work, either. Both ideas represent a negative energy return.
Out of all of the alternative transportation fuels ideas that have come up thus far only 2 have made good sense: battery electrics (70% efficiency) and ethanol from easy growing, sustainable, non-food sources such as switchgrass (around 18% efficiency).
