To do:

1. Stick anemometer in tailpipe

2. Weigh car

3. Weigh car and fuel

4. Plug exhaust velocity, dry mass and full mass into rocket equation

5. Obtain bumper sticker proclaiming my car's total frictionless-vacuum delta-V

your car has an air-breathing engine. Vacuum delta-V=0. No math needed.

Hmmm...could a car with nitrous drive on the moon?

Unlikely, as it's still an air-breathing engine. N2O simply allows more efficient combustion without changing the compression ratio (i.e. more thrust per unit of fuel) but I don't think it could replace air.

That said, nitrous oxide has been used as an oxidizer in closed-cycle rocket engines before, but then they were designed to work that way.
