Mazda 6 Touring 2019

For the third time in five model years, the Mazda 6 receives a makeover for 2018. Its most obvious updates include subtly evolved exterior styling, a refreshed interior, and an additional engine option. The 6's new turbocharged 2.5-liter four-cylinder—which slots above the standard non-turbo 2.5-liter four—adopts cylinder deactivation and adds slightly more horsepower and torque. While these changes are significant, Mazda took things a step further by retuning the chassis and drastically reducing interior noise levels. The lineup also welcomes a new Grand Touring Reserve trim and a top-of-the-line Signature model. The latter has rich leather, real wood trim, and a long list of desirable standard features. The Mazda 6 will also finally add a diesel engine and all-wheel drive to its roster before the end of the year. While complete details haven't been released, we're confident the diesel-powered version will feature the same 2.2-liter four-cylinder found on the Mazda CX-5, which makes 168 horsepower and 290 lb-ft of torque. Likewise, we expect the new engine will only be available on the top-of-the-line Signature model.
