In total refinement, the Mazda 6 ranks a shade behind the pace set by Accord and Camry. Acceleration is tepid in four-cylinder models with automatic; yet overall, the Mazda 6 delivers on its fun-to-drive promise. It’s also as practical as any compact sedan–and even some midsize models. As a result, the Mazda 6 earns a Recommended rating.


Replacing the 626 sedan, the new front-drive Mazda 6 (actually badged “Mazda6”) was a slightly wider, taller, and heavier sedan with fresh styling and more power. The base “i” model used a new 160-horsepower, 2.3-liter four-cylinder engine. The uplevel “s” sedan held a 220-horsepower, 3.0-liter V6, versus the 165-hp 2.5-liter V6 in the departed 626.

Both engines teamed with a manual or automatic transmission. The automatic was a four-speed unit on four-cylinder models, but a five-speed with V6s; both had a separate gate for manual shifting.

All models had four-wheel disc brakes. ABS with integrated traction control was standard on V6 models, and optional for four-cylinder sedans. Front side airbags and curtain side airbags were available for all models. So was a Sport Package that included 17-inch alloy wheels instead of steel or 16-inch alloys, plus a rear spoiler and other aero body add-ons.

Standard equipment included a single-disc CD player, tilt/telescopic steering wheel, and a split-folding rear seatback. V6s added automatic climate control. Options included a sunroof, leather upholstery, heated front seats, in-dash CD changer, and Bose audio. V6s came with a power driver’s seat.

The Mazda 6 competed against both compact and midsize cars, in power as well as marketing focus. Rivals included the Ford Taurus, Honda Accord, Nissan Altima, and Toyota Camry; and later, the redesigned Chevrolet Malibu.

Yearly Updates

2004 6
Wagon and hatchback body styles joined the original Mazda 6 sedan in the spring of 2004. Seventeen-inch wheels were standard on “s” models, and optional for “i” versions. The available Sport Package included special interior trim.
2005 6
Antilock braking and traction control were standard on all 2005 models, and a six-speed automatic transmission replaced the five-speed unit for “s” versions. Mazda’s three body styles came in base, Sport, and Grand Touring trim levels.
2006 6
An available 6-speed automatic transmission and a new MazdaSpeed performance model highlighted Mazda’s 2006 midsize car lineup. MazdaSpeeds were sedans with all-wheel drive and a 274-hp turbocharged 4-cyl. MazdaSpeeds came only with a 6-speed manual and included a sport suspension and specific trim.
2007 6
Curtain side airbags were standard for 2007 on all versions of Mazda’s midsize cars.
2008 6
The 2008 Mazda 6 was little changed, but the wagon and MazdaSpeed models were discontinued this year.


transverse front-engine/front-wheel drive

Mazda 6 models have come with a 2.3-liter four-cylinder engine that produces 160 horsepower, or a 3.0-liter V6 rated at 220 horsepower. A five-speed manual transmission has been standard. The optional automatic transmission is a four-speed for four-cylinder models or a five-speed for V6 versions. A six-speed automatic replaced the five-speed in 2005, for “s” sedans. For 2006, the MazdaSpeed6 performance model gets a 274-hp turbocharged 4-cyl engine with a 6-speed manual transmission.

Road Test

Pleasantly peppy with the four-cylinder engine and manual transmission, a Mazda 6 is dull but acceptable with four-cylinder/automatic. The automatic’s manual-shift feature can be used to restore some lost sparkle. V6 versions don’t exactly spring off the line, and need high rpm to really feel brisk. But they’re lively enough with either transmission. A test manual-shift “s” sedan reached 60 mph in 7.5 seconds. The automatic is smoothly responsive, whereas the manual gearbox has coarse shift action.

Manual-shift V6 sedans have averaged 20.9 mpg in mixed city/highway use, and 18.2 mpg with gas-guzzling performance runs. A four-cylinder/manual-shift sedan managed 22.3 mpg. Mazda recommends regular-grade fuel for both engines.

The Mazda 6 suspension is taut, but generally absorbent and comfortably controlled, even with 17-inch tires. Some sharp reaction to pavement seams occurs at highway speeds.

Mazda aims for sport-sedan moves, and the “6” does feel agile and composed. Suspension settings are essentially the same for each trim level, though 17-inch tires deliver greater grip in fast turns. Modest body lean is evident in curves, but steering is responsive. Great straight-line tracking is a bonus, but the V6 model pulls mildly to the side during rapid acceleration. A wide turning circle impairs close-quarters maneuverability. Brakes are strong, with progressive action.

Both engines are relaxed while cruising, and emit hard-acceleration growls. Neither is super-quiet. Rough-surface tire noise is moderate but prominent with 17-inch treads, but sedans are slightly better than hatchbacks or wagons at muffling road sounds. Wind rush is modest.

Unobstructed gauges are pleasing, but not everyone likes the red Grand Touring lighting. Main climate controls are simple knobs, but a silvery finish makes their markings tough to read in daylight. Audio controls have the same problem, and are also too “busy.” Climate and audio settings display near the center dashtop, remote from the controls themselves. The interior has nicely padded surfaces above door-handle level, but it disappoints with hard, thin-feeling plastic panels below.

Firm front seats are quite comfortable, but some drivers might prefer a longer cushion. Others may desire better lateral support in swift turns. Six-footers have ample leg room and adequate head room. The standard tilt/telescopic steering wheel is a welcome plus, but might not tilt high enough for tall drivers. The optional rear spoiler bisects the rearward view. Wagons provide easy all-around visibility.

Seat support in back is nothing special, on slightly soft cushions. Toe space is good, and leg room exceeds the norm unless front seats are moved well back. Head room is adequate. Entry/exit is easy enough, despite narrow thresholds and doors that could open wider. Center shoulder belts in wagons and hatchbacks are awkward to find and fasten.

The sedan’s flat-floor trunk is nicely finished and roomy. Strut-type lid hinges don’t steal space or threaten cargo, but the opening is not shaped to accept bulky objects. Spring-loaded rear seatbacks with in-trunk or cargo-area releases flop forward without assistance, but don’t quite lie flat. The lidded dashtop bin contributes to above-average interior storage space. Hatchbacks and wagons have spacious, nicely trimmed cargo bays, plus rear under-floor storage.
