If the extra features weren't enough, Mazda doesn't charge anything extra for the trim levels. All the base prices remain the same. The cheapest Sport model, which comes with a manual transmission, still starts at $22,820. The cheapest Touring model, again with a manual transmission, keeps its starting price of $25,070.
Aside from a nice addition of features for no extra cost, there's something else interesting about the 2017.5 Mazda6, and that's the model year itself. The last time Mazda used a half-year designation was for the 2016.5 CX-5. It was the last model year of the previous generation CX-5, with the completely redesigned model launching for 2017. This leads us to believe that we may be seeing a completely new Mazda6 for the 2018 model year, with a reveal sometime within a year. It's possible Mazda could just do a significant refresh for 2018 as well, but the 6 also is the next model due for a complete redesign. And since the folks at Mazda have told us they're in the process of thoroughly updating the lineup again, we would lean toward the likelihood of a completely new car rather than a refresh.
