CARS.COM — Mazda stirred up some excitement when it announced in November the addition of a turbocharged engine to the Mazda6 lineup. Borrowed from the CX-9 SUV and available on higher trim levels, the turbocharged 2.5-liter engine makes 250 horsepower on premium fuel and 227 hp on regular unleaded gas. Now we know what to expect in terms of fuel economy: It's rated at 23/31/26 mpg city/highway/combined according to a new report from the EPA.
The new engine joins the sedan's existing base 184-hp, 2.5-liter four-cylinder, which is rated at 26/35/29 mpg with the six-speed automatic transmission and 24/33/27 mpg with the six-speed manual. Unfortunately for enthusiasts, a manual is only available on non-turbo models.
Competitors with turbo engines offer similar mileage. The Honda Accord with a 2.0-liter turbo and automatic transmission is EPA-rated at 23/34/27 mpg, and the Hyundai Sonata's 2.0-liter turbo with an automatic gets 23/32/26 mpg.
Aside from the new engine option, Mazda lightly revised the sedan for 2018 with a luxurious new top trim, the Signature model, along with slightly freshened exterior styling. The 2018 Mazda6 goes on sale in the spring.
