Engines with an absurdly low efficiency (in the 0.01% range) can produce game breakingly high economy figures. I have a Honda CRX with such an engine *with a non-zero reliability) getting around 1875mpgUK. Also, ifthis type of engine us udes with a car set up to have a top speed of 0.0mph, as I managed to do with the modded passenger van body, you can get an economy figure of infinite mpgUK.
If you want I can attach the engine and cars that do this
*edit*
I can also get 'nan' mpg and -0.0mpg with various car setups using a very low powered engine with sensible economy. This happens when the car's top speed is 0.0mph
*2nd edit*
I think you already know this one, but attempting to run a car on the track with a top speed of 0 gives a lua error which forces the game to close. presumably this will be the same for any car not powerful enough to climb any of the hills
