Top 10 Cheapest Non-Hybrid Cars That Get 40 MPG Highway

7. Ford Focus SE with SFE $20,185

Where the standard Focus sedan nets just 36 mpg on the highway, once you add on the SFE (for Super Fuel Efficiency) package, the car is able to hit 40 mpg. This is thanks to the usual suspects of helpers, like a spoiler for aerodynamics and a set of low-rolling resistance tires. Ford also says that the 16-inch wheels have aerodynamic wheel covers, which add to the car’s high-efficiency hi-jinks. The SFE Package costs just $95 dollars on the SE Focus, but also requires a pricier automatic transmission. Check out our new car buying page to learn more about the Ford Focus.
