Although the Mazda Mazda6 was all new for 2014 and even though the upcoming model year marks the 6's 4th year in its current model cycle, we didn't expect much in the way of major changes for 2017, especially considering underwent a major refresh just last year.

That's because Mazda's midsize sedan has, much like its smaller sibling the Mazda3, aged very well since its introduction - thank you very much. In fact it's our opinion that, despite a number of new entries into the segment, it remains the best-looking vehicle in its class. But as we're wont to say, staying on top in this business involves aiming at a continuously-moving target. Hence yesterday, Mazda announced a number of changes for the 2017 model year.

For 2017, there were no changes made to the exterior of the Mazda6. Also unchanged is what's under the hood: a 2.5-liter, 184-horsepower engine with a choice (in all but the auto-only Grand Touring trim) of a 6-speed manual or 6-speed automatic transmission.

Since the interior of the Mazda6 received a rather extensive makeover last year, this year's changes are limited to the top-shelf Grand Touring trim. When equipped with the Premium Package, buyers will now be able to choose Nappa leather seating surfaces that feature contrast-color piping. Additional Premium Package amenities include i-ELOOP regenerative braking, bright metallic switchgear and trim, a black headliner, heated outboard rear seats and a heated steering wheel that features the same traditional Japanese chidori stitching found in CX-9 Signature models. Standard on all Grand Touring models is a new full-color Active Driving Display as well as a 4.6-inch, full-color TFT meter display

Also new for the Mazda6 is the option – on certain models - of an Advanced Blind Spot Monitoring and Traffic Sign Recognition 6's current i-ACTIVSENSE safety suite that consists of Rear Cross-Traffic Alert, Mazda Radar Cruise Control, Smart City Brake Support and Smart Brake Support for highway speeds.

Topping off the list, buyers of the entry-level Sport model no longer have to choose an automatic to receive Mazda Connect, as manually-equipped Sport models now come equipped with this feature, as well.

Improvements to the body and chassis include improved door seals, tighter tolerance between panels, sound insulation materials added to the underbody, rear console, headliner and doors along with thicker front glass to reduce wind noise. Grand Touring models also receive laminated front side windows.

The big news, however, is that all Mazda6 models now come standard with the brand's G-Vectoring Control (GVC). The system uses the engine in conjunction with the steering, throttle inputs and suspension to provide sharper chassis control while reducing the need for steering corrections.
