If you’re wondering what “MPS” stands for, don’t bother. All you need to know is that there’s an excellent chance this steroid-infused Mazda 6 will come stateside next year wearing a Mazdaspeed 6 badge. Motivation comes from a newly developed direct-injection MZR 2.3-liter four-cylinder engine featuring a single-scroll turbocharger and a relatively high compression ratio of 9.5:1. Paired with a standard six-speed manual with triple-cone synchronizers for first, second, and third gears, the 2.3 turbo delivers its 256 horsepower and 280 pound-feet of torque to Mazda’s new Active Torque Split all-wheel-drive system. Mazda claims torsional rigidity has been improved by around 50 percent compared to the standard 6, and the front control arm and rear multi-link suspension is considerably sportier, with larger anti-roll bars and stiffer springs and dampers. Rounding out the package are more aggressive front and rear fascias, flared side skirts, and 18-inch alloy wheels with 215/45R-18 tires.
