The Mazda6 is a well-built and sharp driving medium-size car. It falls behind some competitors in rear seat and boot space.

The good
  • Stylish good looks
  • Engines and transmission perform well while being very efficient
  • Feels premium and well built
The not-so-good
  • The boot is a little small for this size of car
  • Rear headroom is restricted

The Mazda6 is a continuation of the 626 model in Mazda’s range. This generation, launched in 2012, grew in size to take on larger cars like the Toyota Camry and Honda Accord. For the first time, no liftback model is available, only a sedan and station wagon. The Japanese-import version is called the Atenza.

Inside and out

The Mazda6 looks more sculpted and stylish than other Japanese medium-size sedans. It looks long and low - almost stretched. The nose features a large Mazda family grille, with a prominent bulge in the bonnet and swept-back headlights. The rear roof-line is angled down into the boot lid, which has a small spoiler moulded into it.

The quality of the interior is impressive, with soft-touch plastics and fabrics at most of the places your hands touch. The gauges are set into pods, and in the right-hand pod is a vehicle information screen. The steering wheel carries stereo, cruise control and Bluetooth phone system buttons. The centre console houses the infotainment system, which is controlled by a panel of buttons and a dial between the seats. This system is updated in 2015 to a larger 7-inch screen.

The front seats are impressive, well sculpted with a supportive firm base.

They have a wide range of adjustments, though on the GSX this is manual and not electric. The rear seats are less impressive - there is good legroom, but headroom is in short supply. Adults 180cm tall may find their heads brushing the ceiling. The raised centre section means while there is width for three rear passengers, the person in the middle may be uncomfortable.

At 474 litres the boot on the Mazda6 is small for the class, with four large cases likely to fit. The rear seat splits 60/40 and folds forward for larger items - though there is no ski port if you want to carry something narrow while still using two rear seats. The opening is wide and low - which makes it easy to load.

On the road

Three engines are available in the 6, a 2-litre four-cylinder petrol, a 2.5-litre four-cylinder petrol and a 2.2-litre four-cylinder turbocharged diesel. The engines are particularly frugal, and use what Mazda calls "Skyactiv" technology, which includes a system that collects energy when braking, a start-stop system, and a high-compression, direct injection engine for efficiency. 

The 2.5-litre engine in the review vehicle is 138kW and 250Nm. The transmission is a six-speed automatic that can be shifted manually through paddles on the steering wheel. Performance is good, with quick acceleration around town and relaxed, quiet cruising on the open road. Most overtaking moves will be dispatched quickly.

The handling is also excellent. The ride is firm yet comfortable, and the steering direct and responsive. The brakes have a good feel to them and stop the car quickly. Road and engine noise is low.

The sculpted nose and rear end make the Mazda6 a little tricky to park in tight spaces. Luckily all models get a reversing camera as standard, and the GSX and Limited get front and rear sensors.

The Mazda6’s tow rating is average for a car of this size. It can handle 550kg unbraked (a small garden trailer) and 1,500kg braked (a small trailer boat). From 2015 the ratings rise to 750kg and 1,600kg respectively.


The Mazda6 has a five-star ANCAP rating. Standard safety features include front, side, and curtain airbags, seat belt reminders, electronic brakeforce distribution, emergency brake assist and electronic stability control. The GSX and Limited get blind-spot detection and an emergency spot warning. The Limited model features lane-keeping warnings and adaptive cruise control.

ISOFIX child seat mounts can be found in the rear seat window positions. All three rear passengers get full shoulder-style belts, which offer more protection than a lap-only belt.


This generation Mazda6 has so far proven to be very reliable. All the engines use timing chains which will not require regular replacement. Mazda offers free servicing for the first three years of a new car's life, which makes the chance high that the car has been serviced correctly.

Note if you are considering the diesel model: They need to be taken on an open road drive occasionally to allow the filters to be cleared. If this does not happen oil contamination may occur. If you are buying a car just for short trips to the shops - stick with the petrol models.

Cost of ownership

Mazda suggests servicing the Mazda6 every 12 months or 15,000km, whichever comes first. A local Mazda dealer says this service should cost from $280.

Over 14,000km of driving a year, RightCar says the GSX will cost $1,850 a year to fuel - very low for a petrol car of this size. The 62-litre fuel tank will cost $124 to fill and should take you 860km before the fuel light comes on.

A vehicle licence for the Mazda costs $76.92 a year, with the car in the cheapest ACC levy group.

Cover for a 6 valued at $22,990 is estimated by Trade Me Insurance to cost $56.62* per month, $4 more than a Ford Mondeo.

Buyer's guide

This generation Mazda6 is available on Trade Me from $13,500 to nearly $50,000 - the most expensive are near-new demonstrator models at Mazda dealers. As the model is popular with fleets, there is usually a good supply of three to four-year old cars with full-service histories available.
