This edition of the Mazda6 arrived as a 2014 model on a new platform. We got an excellent 32 mpg overall from the smooth four-cylinder and six-speed automatic. Acceleration doesn't suffer for fuel economy, with the Mazda6 returning slightly above average performance. The car is also agile and capable in corners, with a taut but firm ride. However, the cabin is loud, particularly on the highway; updates for 2016 helped some. The well-finished cabin has supportive seats, although the rear seats are relatively tight for this class. The infotainment system uses a console-mounted knob; figuring out how to use the system takes some time. Among the optional active safety features are blind spot monitoring, rear cross traffic alert, forward-collision warning, and automatic emergency braking. The Mazda6 underwent a major refresh with the 2018 model, improving ride comfort and noise isolation. An uplevel turbo engine for top versions is new.
