2018 MAZDA 6 l EXTERIOR & INTERIOR DESIGN. Mazda6 has received improvements every year it has been on sale. Updates for the previous model year added more sound insulation throughout its cabin and available Nappa leather interior appointments. Mazda6 also received standard G-Vectoring Control, a Mazda-exclusive technology that makes steering response more direct and linear by using a minute reduction of engine torque at turn-in to put extra weight on the front tires.Mazda6 offers two powertrain options in the U.S., starting with the torquey, fuel-efficient SKYACTIV-G 2.5 naturally aspirated engine. Mazda6’s 2.5-liter, four-cylinder engine comes with a host of upgrades to reduce internal friction and improve efficiency across all RPM, and it adds a greater level of refinement. A new technology that is unique to Mazda in North America is cylinder deactivation in a four-cylinder engine. The outside two cylinders can shut down when the vehicle is operated at steady speeds between 25 and 50 mph, but all four cylinders work instantaneously when needed for maximum performance. A centrifugal pendulum has been adopted in the torque converter of the six-speed SKYACTIV-DRIVE automatic transmission, counterbalancing any vibration that might otherwise be felt when running on two cylinders. The result is an imperceptible switchover between two- and four-cylinder modes, yet with very tangible real-world efficiency benefits.
Higher-grade models will also be available with Mazda’s award-winning turbocharged SKYACTIV-G 2.5T engine. First available in the current-generation Mazda CX-9 midsize crossover SUV, the SKYACTIV-G 2.5T is a technological tour de force that produces 310 lb-ft of torque from just 2,000 RPM and 250 horsepower on 93-octane fuel (227 horsepower with 87-octane gasoline).
