The 2018 Mazda6 made its debut at the 2017 Los Angeles Auto Show, but the automaker waited until now to unveil the turbocharged sedan’s fuel economy figures.
For the 2018 model year, the Mazda6 benefits from a 2.5-liter turbocharged four-cylinder engine that’s taken from the CX-9 SUV. The motor is good for 250 horsepower and 310 pound-feet of torque and features a six-speed automatic gearbox. With the turbocharged engine, the new Mazda6 returns 23 mpg in the city and 31 mpg on the highway, which comes out to a combined rating of 26 mpg.
Those figures are, understandably, not as good as the 2.5-liter, non-turbo four-cylinder engine that's also on offer – it can achieve 26 mpg in the city and 35 mpg on the highway. But the turbo's numbers are competitive with the other midsize sedans on the market.
The majority of the Mazda6’s competitors, which include the Hyundai Sonata, Kia Optima, Toyota Camry, Buick Regal, Nissan Altima, and Chevrolet Malibu, have a combined rating of 26 mpg. The Malibu, Sonata, and Regal are fitted with turbocharged 2.0-liter engines, while the Camry and Altima have naturally-aspirated V6 engines.
The Honda Accord is another new sedan in the midsize segment that comes with a 2.0-liter turbocharged four-cylinder engine. The motor helps the sedan get three more mpg than the Mazda6 on the highway and has a combined rating that’s better than Mazda’s offering by one mpg — 27 combined.
