10. Mazda2: 1.5L (1498 cc)
In an effort to make the most fuel efficient vehicles, automakers are looking at smaller displacement engines, which have made it into plenty of compact and subcompact vehicles.
The motors in these vehicles don’t pack much power, or torque, and are all aimed to use the least amount of fuel. These cars are all ranked in order, right down to the cubic centimeter from most displacement, to least, so take a look below, to see the list of smallest engines available today.
The subcompact Mazda2 is the first on our list, with the biggest engine here. Thanks to its 1498cc four-cylinder engine, the Mazda2 makes 100-hp at 6000 rpm. Of course, that’s not much but what else do you need in a 2300-lb city car? The Mazda2 starts at $14,530 which isn’t too much for a car that gets 29/35 mpg city/highway with the manual or 28/34 mpg city/highway with the auto.
