STATUS: Diesel engine added for 2020 - The popularity of utility vehicles has pushed midsize sedans out of the spotlight, but that's not stopping Mazda from being innovative with the Mazda6. For the 2020 model year, the automaker is adding a turbo-diesel engine to the powertrain lineup. The 2.2-liter SkyactivD, which is also available in the Mazda CX-5, is rated at 168 horsepower and 290 pound-feet of torque and comes with all-wheel-drive. What's interesting is that engine uses a small turbo (for more immediate throttle response) and a larger one (for more top-end power). It joins the mid-2019 addition of an optional turbocharged gasoline 2.5-liter four-cylinder. Depending on the octane of the fuel used, it makes either 227 or 250 horsepower. This engine gets six-speed automatic transmission. A 184-horsepower non-turbo four-cylinder is the base engine, mated to a six-speed manual transmission (the six-speed automatic is optional). Among the sedan's technical highlights is G-Vectoring control, a system that temporarily reduces engine torque when the driver enters a turn, resulting in more g-force over the front axle for improved steering response.
