32 City / 40 Highway / 35 Combined
$15,450

The Mazda-based, Scion-faced Toyota Yaris sedan doesn't look much like the rest of the lineup, but its efficiency stays the course with other Toyota products (some you'll see later on this list). The 1.5-liter four-cylinder produces a mere 106 horsepower (79 kilowatts) but helps return 32 miles per gallon in the city, 40 highway, and 35 combined. Annual fuel should set owners back about $1,050.
