When shopping for a new car, there often comes a time when you have to choose between power and fuel economy. But why? Surely, with modern technology such as turbocharging and cylinder deactivation, it’s possible to build an engine that is powerful when you want it to be, but also economical when you need it to be.
In order to qualify, we’ve arbitrarily decided that the engine must produce at least 350 horsepower (to be considered powerful), and that the vehicle in which the engine is installed must be rated 20 mpg combined or better (to be considered fuel efficient). In order to sort the engines, we’ve given them each a score which is calculated by multiplying the engine’s horsepower by its combined fuel economy rating. Let’s take a look at our list of cars with the most powerful fuel efficient engines, and see if it really is possible to have your cake and eat it, too.
