Fuel efficiency is one of the most important considerations for customers when buying a car. This is because fuel prices could significantly increase car ownership and maintenance costs. As such, automakers strive to get high fuel economy numbers every time they release a new model in the market.<\/p>\n\n\n\n

In the United States, the Environmental Protection Agency (EPA) is in charge of imposing emissions regulations and ensuring that vehicles abide by the laws by measuring their fuel economy numbers. In a report recently published by the agency, it named the most and least fuel-efficient cars in the US for the coming 2021 model year.<\/p>\n\n\n\n

In the category for performance-based vehicles, the 2021 Toyota GR Supra and BMW Z4<\/a> topped other two-seaters with 2 mpg, while the Mini Cooper SE Electric led electric vehicles with its 108 MPGe that made it the most efficient subcompact.<\/p>\n\n\n\n

\"volvo
The Volvo Polestar 1 was among the most efficient mini-compact cars. <\/figcaption><\/figure>\n\n\n\n

In the compact segment, the Toyota Corolla Hybrid took the top spot with 52 mpg, while the Tesla Model 3 Long Range AWD and Tesla Model S Performance led the midsize and large vehicle segments with 134 MPGe and 110 MPGs combined economy, respectively.<\/p>\n\n\n\n

Volvo’s Polestar 1 was also among the most efficient mini-compact cars with 45 mpg combined, while the Volvo V60 AWD PHEV, also with 45 mpg combined, ranked first among station wagons. The Volvo 90 FWD with 26 mpg combined is the most efficient midsize station wagon.<\/p>\n\n\n\n

For the least efficient 2021 vehicles, EPA lists the Bugatti Chiron Pur Sport, Lamborghini Aventador Coupe, and Lamborghini Aventador Roadster.<\/p>\n\n\n\n

Among the luxury cars, the Bentley Continental GT Convertible and Coupe (15 mpg); Rolls Royce Dawn, Wraith, Ghost, Phantom, and Cullinan (15 mpg); Mercedes-Benz AMG GLA35 4matic, Subaru Impreza<\/a> Sport 5-Door, and Volvo V60 CC AWD (25 mpg) were named the least efficient in their respective classes.<\/p>\n<\/body><\/html>\n","protected":false},"excerpt":{"rendered":"
