Used 2018 Mazda 6 Sedan Trims Comparison

The entry-level Sport starts with a 2.5-liter four-cylinder (187 horsepower, 186 pound-feet of torque) and a six-speed manual transmission. (A six-speed automatic is optional.) Standard equipment includes 17-inch wheels, LED headlights, push-button start, 60/40-split folding rear seats, non-illuminated vanity mirrors, and a leather-wrapped steering wheel.

An 8-inch entertainment touchscreen comes with Bluetooth, one USB port and a six-speaker sound system. Standard safety features include blind-spot monitoring, a rearview camera and rear cross-traffic alert.

Advanced safety and driver assistance features are available in the optional i-Activsense package, which includes forward collision warning with automatic emergency braking, adaptive cruise control, and lane departure warning and lane keeping assist.

It's worthwhile to step up to the Touring trim, which adds features throughout the vehicle. A six-speed automatic is standard, as are 19-inch wheels, a sunroof, proximity keyless entry, automatic wipers, automatic high beams, simulated leather upholstery, heated front seats, a power-adjustable driver's seat, illuminated vanity mirrors, and Android Auto and Apple CarPlay smartphone integration (late availability). Rear passengers get additional vents in the center console and a center armrest with two USB charging ports. The safety features of the i-Activsense package are standard with the Touring, too.

The Grand Touring starts where the Touring leaves off, but it adds the turbocharged 2.5-liter four-cylinder engine (250 hp, 310 lb-ft of torque) and the six-speed automatic. The infotainment system gets more power, too, with the addition of an 11-speaker stereo, satellite radio and navigation.

You can tell the Grand Touring Reserve apart by its upgraded LED lighting and the addition of a rear spoiler. Comfort improvements for the driver include a heated steering wheel, a power-adjustable front passenger seat and driver-seat memory functions. There's leather seating for everyone else, along with ventilation for the front row and heating for the rear. Above the gauge cluster sits a transparent panel that works like a head-up display, showing information such as traffic signs and your current speed. This trim also has adaptive front lighting, which turns the low beams in conjunction with the steering wheel to improve visibility at night.

Aside from the addition of a gunmetal front grille, the fully loaded Signature trim level primarily improves the look and feel of the interior. You'll find higher-quality materials such as microfiber suede, wood and upgraded leather, along with the addition of LED interior lighting and a frameless rearview mirror. Other feature additions consist of a digital gauge cluster and a surround-view camera system with front and rear parking sensors.
