• 2018 Mazda3 Grand Touring Quick Specs

Digging through the numbers

The Mazda3 has been around since 2003, but the current version debuted for the 2014 model year. Thankfully, Mazda hasn’t let it trudge through the last four years unchanged. Small updates each year have kept it fresh. The same is true for the 2018 model year, which is exactly why I wanted to test the latest version. Parked in my driveway is a 2018 Mazda3 5-Door Grand Touring coated in Soul Red Metallic and equipped with the six-speed automatic and the well-equipped Premium Package.

Like before, the Grand Touring trim is the highest of the Mazda3 range, and when combined with the Premium Package, offers some pretty nice features, creature comforts, and a strikingly classy ambiance for well under $30,000. But before I dive into my subjective thoughts and impressions, I wanted to cover the objective stats and specs of this Japanese hatchback.

Exterior Specs

The 2018 Mazda3 5-Door is a compact hatchback with a small footprint. With a total length of 180 inches, the 3 will fit just about anywhere. Yet, thanks to its wheelbase of 106.3 inches and track of 61 inches, it has a stable ride at highway speeds and around corners. Best of all, the car is pretty light at only 3,098 pounds. That means its 184-horsepower four-cylinder has less to move. It also helps with fuel economy, too.

Wheelbase (inches) 106.3
Length (inches) w/License Plate Holder 180.3
Width (inches) w/o Body Side Protector 70.7
Height, unladen (inches) 57.3
Track front/rear (inches) 61.2/61.4
Curb Weight (lbs.) 3,098

Interior Specs

As compact as the Mazda3’s exterior is, its interior is impressively spacious. Front occupants have a good amount of room, with 42.2 inches of legroom and 38.6 inches of headroom. And despite the car’s track being only 61 inches wide, the front occupants enjoy 57.2 inches of shoulder room.

Rear passengers have a bit less room, though, measuring 35.8 inches in legroom, 37.6 inches of headroom, and 54.4 inches of shoulder room. Still, the back seat is just fine for kids and will easily accommodate two adults on anything shorter than a road trip.

The 5-Door’s advantage is cargo room. There are 20.2 cubic-feet of cargo room behind the second row and 47.1 cubic feet of room with the 60/40-split bench folded flat.

Headroom, front/rear without Moonroof (inches) 38.6/37.6

Drivetrain Specs

While the Mazda3 comes standard with a 2.0-liter SkyActiv four-cylinder, the Touring and Grand Touring trims come with the more powerful 2.5-liter SkyActive four. The engine makes 184 horsepower at 5,700 rpm and 185 pound-feet of torque at only 3,250 rpm. A silky smooth six-speed manual comes standard, but the optional six-speed automatic transmission is available.

The sprint to 60 mph takes only 6.8 seconds, and its top speed is listed at 130 mph. Fuel economy is slightly more impressive, though not class-leading. The EPA estimates the Mazda3 5-Door with the automatic at 26 mpg city, 35 mpg highway, and 30 mpg combined. Staying with the manual transmission reduces each figure my one mpg.

Engine Type-SKYACTIV-G 2.5L DOHC
Horsepower 184 HP @ 5,700 RPM
Torque 185 @ 3,250 RPM
Transmission SKYACTIV-MT 6-speed manual
Optional Trans SKYACTIV-DRIVE 6-speed automatic
Fuel economy 25 / 34 / 29 (Manual trans)
Fuel economy 26 / 35 / 30 (Automatic trans)
Top Speed 130 mph

The 2018 Mazda3 5-Door starts at $19,345. Comparatively speaking, that’s a reasonable price. The Volkswagen Golf starts at $20,715, the Honda Civic Hatchback starts at $19,730, the Hyundai Elantra GT starts at $20,235, and the Chevrolet Cruze Hatchback starts at $22,195.

My Grand Touring tester with the automatic transmission carries a base price of $24,945. Several á la carte options add cost, but also add convenience and style. These items include the $75 cargo mat, the $300 Soul Red Paint, the $100 rear bumper guard, the $125 scuff plates and door sill trim plates, and the big one – the $1,600 Premium Equipment Package.

The Premium Equipment Package adds navigation, paddle shifters, adaptive front lighting, smart brake support, radar cruise control, traffic sign recognition, auto-dim rearview mirror with HomeLink, a heated steering wheel, automatic high beams, lane departure warning, and lane keep assist. Needless to say, that $1,600 is well spent.
