you know V8's can get Turbo's installed too right? comparing an N/A motor to a Turbo motor isn't a fair comparison to begin with regardless the number of cylinders, a Turbo motor is naturally going to get a more complete burn of the fuel due to forcing more oxygen into the combustion chamber, Yes as it sits the Turbo 4 Cylinder itself is converting more of the fuel into usable energy vs heat, but the engine is only 1 part of the equation to the overall efficiency of the car, you have drag coefficients, gearing, horsepower to weight ratio's and the driver all effect how FUEL efficient a car is, My point is a V8 is not necessarily a "gas guzzler" (meaning poor fuel economy), it depends how it's used, you seem to be purely talking about the energy efficiency of the motor alone and using that to make V8's sound like the devil, my point is it depends how you use it, take for example a recent project from Legit Street Cars on Youtube, he bought a C5 vette and has been tuning it to get increased fuel economy on the highway with a target of 40 MPG which is about what our cars are capable of, as he achieves this he is traveling the same distance we do at the same cost of fuel but with a MUCH larger motor, I would argue that is being more efficient because he is using the same amount of fuel to move a larger vehicle even if on a Horsepower to Displacement ratio his engine efficiency is less.wow, seems I struck a nerve. it's basic physics. a V8 will never be as efficient as a turbo-charged 4 cylinder, all else being equal. that's the point of a turbocharger. sure, V8s are way more efficient than they used to be, but so are ICEs across the board.
