Showing just how inefficient a petrol engine is.

Perhaps you'd better set about a more efficient way of converting a
high density fuel like petrol to mechanical energy, then. Electric
vehicles driven off storage batteries have been around for nearly as
long. If they were capable of being developed into a viable competitor,
it would have been done years ago.

Try diesel. Or indeed any compression ignition engine.

They're still incredibly inefficient compared to a decent electric motor
- energy in against energy out.

Also, the difference between a petrol and diesel of similar output both
at full power isn't that great.
