BMW makes for two returns on the list this year, first with its 2.0-liter turbocharged four-cylinder that’s currently found in its 328i sedan models. Combining the best of both worlds: fuel efficiency and performance, the 240-hp engine is further benefited by a twin-scroll turbocharger providing plenty of low-end torque and driving pleasure. Best of all, the 328i gets close to 30 mpg thanks to its eight-speed automatic transmission.
