Some performance-focused cars deliver better fuel economy than you might think.

Fuel efficiency is an important factor to consider when buying a new car as frequent trips to the gas station can increase annual running costs considerably. But if you can afford to buy a high-performance sports car or supercar, chances are fuel economy won't be your highest priority. However, some performance-focused cars deliver better fuel economy than you might think.

The Environmental Protection Agency has rounded up the best and worst economy vehicles for the 2021, and there are some interesting results. Topping the list of the most fuel-efficient 2021 two-seaters is the 2021 Toyota GR Supra 2.0 and BMW Z4 with both cars delivering 28 mpg, which is impressive. While the Mini Cooper SE Electric has a disappointing driving range, it makes up for in fuel economy with 108 MPGe, making it the most efficient 2021 subcompact.

The Toyota Corolla Hybrid takes the top spot in the compact class with 52 mpg, while the Tesla Model 3 Long Range AWD and Tesla Model S Performance earned top rankings in the midsize and large vehicle classes with 134 MPGe and 110 MPGe combined respectively.

Surprisingly, some of Volvo's performance-focused models also made the list including the Polestar 1, which is the most efficient mini-compact delivering 45 mpg combined. The Volvo V60 AWD PHEV also took top honors in the small station wagon class with 45 mpg combined, while the Volvo V90 FWD is the most frugal 2021 midsize station wagon rated at 26 mpg combined.
