32 City / 41 Highway / 35 Combined
$21,390

The base 2020 Toyota Corolla SE Hatchback with the continuously variable transmission is the most efficient member of the popular Corolla clan, returning 35 combined mpg. This setup packs an adequate 168 hp and 151 lb-ft of torque into a package that starts at a very reasonable $21,390, a price that includes the $675 premium for the CVT. If you prefer a Corolla Sedan, the 2.0-liter variant with a CVT is good for 34 mpg combined. This engine is only available on the SE trim and above for the Sedan, though, which starts at $22,050.
