In short, it is primarily size that sets these two apart. And, with new updates to the 2017 Mazda3, it’s more like its big brother than ever before. Still, each has its own idiosyncrasies, plus unique fanbases that will want to choose one sedan over the other.
The 2017 Mazda3 is the smaller of the two sedan options. The Mazda3 also comes in a 5-door hatchback style. Its smaller size makes it a slightly zippier drive. However, both the 2017 Mazda3 and the 2017 Mazda6 get improved driveability. This model year introduces a new standard called G-Vectoring Control. This Mazda-exclusive technology tweaks steering, throttle and suspension to create an all-around better driving experience.
The 2017 Mazda3 is also updated with a roomier interior, a new standard electronic parking brake and a sliding center console that matches that in the 2017 Mazda6. The Mazda3 gets two engine options. Choose between the 2.0-liter, 4-cylinder engine or the 2.5-liter 4-cylinder engine. The latter is the standard in all trims of the 2017 Mazda6.
The 2017 Mazda6 gets updated in its own unique way with enhanced soundproofing technologies and update safety features, making this roomier version of the two sedans a great choice for family transportation or long road trips.
