Read about the new Mazda6 »

The 2018 Mazda6 is part of a generation that began with the 2014 model year. In years past, each new Mazda6 model gained a few new features. For example, the 2016 model got standard Bluetooth and a larger infotainment screen, while the 2017 model added the MazdaConnect infotainment system and a rearview camera to the standard features list.

For 2018, the Mazda6 gained several substantial updates as part of a refresh. Mazda introduced two new trims and a new engine to the lineup (a 250-horsepower turbocharged four-cylinder), upgraded the interior materials, and added many new standard and available features, including heated rear seats, ventilated front seats, an 8-inch touch screen, and more. If you buy used, we recommend sticking with the 2018 model.

What Does Mazda's Certified Pre-Owned Warranty Cover?

Mazda offers a certified pre-owned program for vehicles six years old or less and with fewer than 80,000 miles. Eligibility is determined by the vehicle’s initial sale date. Mazda extends the original limited powertrain warranty to seven years from the original sale date or 100,000 miles and provides a one-year/12,000-mile limited warranty after the expiration of the original three-year/36,000-mile warranty. Every CPO Mazda must pass a 160-point inspection. Additional benefits may include towing, a 90-day complimentary SiriusXM satellite radio trial subscription, extended coverage, and 24-hour roadside assistance, so read the Mazda warranty page carefully.

According to our research, Mazda’s CPO program is about average for an affordable auto manufacturer. Honda, Hyundai, and Kia all have better programs.

2018 Mazda6 Versus the Competition

Which Is Better: 2018 Mazda6 or 2018 Toyota Camry?

The 2018 Toyota Camry finishes much higher than the Mazda6 in our midsize car rankings, and with good reason. It's just as fun to drive as the Mazda6, but it has stronger engines and gets better gas mileage. The Camry has an attractive interior, two rows of spacious seats, and slightly more trunk space than the Mazda6. The Camry also has more standard driver assistance features than the Mazda and a much higher predicted reliability rating.

Which Is Better: 2018 Mazda6 or 2018 Honda Accord?

The 2018 Honda Accord may not match the Mazda's performance chops, but it's in the conversation. It also gets better gas mileage. Inside, the Accord is quiet and comfortable. The rear seats are more spacious than almost every rival, and the Accord has roughly 2 more cubic feet of cargo space. The Honda offers a lengthy list of standard and available features, including things like Apple CarPlay and Android Auto, which you can't get in the 2018 Mazda6.

2018 Mazda6 Performance

How Does the 2018 Mazda6 Drive?

The Mazda6's base engine gets the job done when driving around town, but it can feel underpowered in demanding situations like highway passing and climbing hills. It also makes a fair bit of noise at higher rpm. The turbocharged engine delivers superior acceleration and never feels overmatched, making it a much more enjoyable power plant.

Speaking of enjoyment, few midsize cars can match this Mazda's sporty feel, making it one of the most fun-to-drive cars in the class. It's agile and stays planted around turns, and it has sharp steering. It also rides smoothly over most road surfaces.

  • Base engine: 187-horsepower 2.5-liter four-cylinder
  • Available engine: 227-250-horsepower turbocharged 2.5-liter four-cylinder (horsepower depends on what grade of gasoline you use)
  • Drivetrain: front-wheel drive
  • Transmission: standard six-speed manual; available six-speed automatic (standard with the turbo-four engine)
Does the 2018 Mazda6 Get Good Gas Mileage?

With the base engine and the automatic transmission, the Mazda6 gets average fuel economy for a midsize sedan. Rivals like the 2018 Toyota Camry and 2018 Honda Accord earn better ratings.

  • Base four-cylinder, manual transmission: 24/33 mpg city/highway
  • Base four-cylinder, automatic transmission: 26/35 mpg
  • Turbo-four: 23/31 mpg

2018 Mazda6 Interior

How Many People Does the 2018 Mazda6 Seat?

The 2018 Mazda6 seats five people in two rows. Its cabin looks great, and the materials quality stands out in the class, coming in at near-luxury levels. The front seats are spacious and supportive. The rear seats are comfortable, but they aren't as roomy as some rivals' rear seats. You also have to duck a bit to climb into the back because of the sloped roofline.

Standard seating features:

  • cloth upholstery

Available seating features:

  • synthetic leather upholstery
  • genuine leather upholstery
  • power-adjustable front seats
  • heated front seats
  • ventilated front seats
  • heated rear seats
  • heated steering wheel
How Many Child Car Seats Fit in the 2018 Mazda6?

The 2018 Mazda6 has two complete sets of LATCH car-seat connectors on the rear outboard seats and an upper tether on the rear middle seat. The Insurance Institute for Highway Safety gave the Mazda6's LATCH system the highest ease-of-use rating of Good+.

2018 Mazda6 Features

The MazdaConnect infotainment system comes with a touch screen, but the display only responds to touch inputs when the car is parked. You must use a rotary dial controller to adjust settings while on the go. Beyond that quirk, the system works well. It has a user-friendly interface, and the screen is easy to see. You have to go through multiple steps for some functions, however, and it lacks support for Apple CarPlay and Android Auto.

  • Standard infotainment features: a six-speaker audio system, HD Radio, Bluetooth, a USB port, and an 8-inch touch screen
  • Available infotainment features: two additional USB ports, an 11-speaker Bose audio system, satellite radio, and navigation
