Electric motors are in general, a lot more efficient that internal combustion engines. An average combustion engine has about 18â20%. A formula one engine, has about 50% of an efficiency.
Diesel cars are much more fuel efficient than gasoline, 33 percent more efficient as a matter of fact. This means that if you normally get 24 miles per gallon with gas, a diesel engine would provide 32 miles per gallon. This is a big difference, and provides cost savings in the long run.
