Conventional cars operate at around 15% thermal efficiency. Tell us about what 3000% efficiency might mean, please.

Of course we could reduce air drag and rolling resistance to some degree, and we could accept operation at lower speeds for less drag. But please tells us what you mean by "200 times more efficient."

I have been aware for
a long time that we can run the humble old combustion engine at rates 200
times more efficient than conventional running.
