  • Petrol, or gasoline for non-British, is a liquid fuel. You can't have an internal combustion engine with a solid fuel. Coal was used for some of the first experiments with "horseless wagons", using an external combustion engine similar to steam-powered locomotives of the time. An internal combustion engine is simply far more efficient, and less bulky.

  • Who heard of a car that uses coal? Lol:)
