Mazda has given the Mazda 6 a facelift for 2017 and while it does not look like there is going to be much of a difference based on the exterior design, they did do something to it.
One of the biggest updates will probably be the new G-Vectoring Control that the 2017 Mazda 6 will come with. While the difference it makes is not the obvious, it will help improve the steering response of the vehicle and thus improve the overall driving experience of the vehicle. The 2017 Mazda 6 will also come with the i-Active sense which will help detect pedestrians.
On the inside, the Mazda 6 will come with a new steering wheel, a new full-color TFT screen, heating tech, pop-up head-up display and more. The Mazda 6 will also be getting a thicker glass, upgrade seals and weather stripping to that the cabin is quieter now.
There is also the new Premium Package which will be offered on the Mazda 6 Grand Touring model which will come with a long list of exterior and interior design upgrade.
