We know that the Mazda 6 will only be coming with some exterior upgrade and that is not the reason why we think the Mazda 6 is not going to be worth again, it is because the 2017 will still be coming with the same engine that the Mazda 6 is offering.
While the engine is sufficient, fans were hoping that the 2017 Mazda 6 would come in with an upgraded engine. Mazda did show off the new Mazda CX-9 engine and according to the automaker, the CX-9 was designed so that it is able to fit into any other Mazda models. Although the Mazda 6 should be included, Mazda just does not have enough time to fit it into the 2017 Mazda 6.
Fitting in a new engine would mean more testing and upgrade so that the engine performance well on the vehicle and Mazda just does not have the time. We will probably see the engine under the hood of the Mazda 6 in the future but not the 2017 model.
