Which car has the highest fuel efficiency?

Title says it all. How much fuel can you save in this game?

 

Wat ? It's not like if you had to paid for fuel in beam x) I think if not that the pigeon, the covet, and the low end sunburst are probably the best in terms of fuel efficiency, because the pigeon, well, use a bike engine, the covet is a small city car, and the lower end sunburst, because it's a modern city car.

We had a dictated course and tried different vehicle configurations to see what kind of fuel economy we'd get. My absolute best was the base Pigeon at 74.5 MPG, but most of that was in neutral.
