Why are Turbo 4cyl engines Fuel efficient and V6/V8 Turbo’d engines not equivalent or better?
In: 5
If you compare a naturally aspirated V6/V8 to a blower V6/V8 if tuned for efficiency then the blown versions would be more efficient than the NA version. But V6/V8 are usually only blown for big performance gains which takes extra fuel.
You can look at a blown V8 like two inline-4 connected together at the crank. For each mile driven by the V8 it’s basically using the same gas as two 4cyl engines (not 100% accurate, but it’s a good analogy) because the V8 is more mass being moved in each revolution of the crank and each cylinder gets the same amount of fuel.
