Mazda's flagship model, the all-new Mazda6, sedan version. 

30 Nov. 2012, Gaby Sakr: Last spring, Mazda teased the midsize car markets with its Takeri concept car, which was inspired by the 2010 Mazda Shinari concept car. Finally the two concepts materialised in the all-new, third generation Mazda6, with significantly larger dimensions and advanced technologies such as i-ELOOP and i-Activsense.

Launched earlier this month in the brand's domestic market, the 4-door sedan (saloon) and wagon (also known as estate, break, tourer or station wagon in different markets) body versions will reach the other world markets from early 2013. However, the previous 5-door hatchback is not part of the new line-up.

With over 2.4 million Mazda6 units sold since the launch of the first generation in May 2002, Mazda aims for an annual sales figure of 240,000 units for this 3rd generation, in over 120 countries including Australia, China, throughout Europe and North America, bearing in mind that the model will be produced in China, Russia and in Hofu, Japan, where the model is called the Mazda Atenza. At around 1,000 monthly units, the Hiroshima based company expects its domestic sales of the Atenza to reach 5 percent of the global Mazda6 sales.

The new Mazda6 sedan is one the largest D-segment models.

In the UK, the new Mazda6 will be available from early 2013 at on-the-road prices of £19,595 to £27,295 for the 4-door sedan and £21,256 to £28,045 for the estate.

In the USA, prices of the sedan are expected to start from around $22,000 with the 2.5-litre gasoline engine.

As Mazda's flagship model, the all-new Mazda6 adopts the company's new-generation Skyactiv technologies and the new design theme, KODO (soul of motion), presented with the Mazda Shinari concept car.

Despite its generous dimensions, the new Mazda6 is lighter than its smaller predecessor, thanks to the Skyactiv technologies, launched first with the new CX-5 compact crossover SUV, which was elected yesterday as the car of the year 2012-2013 in Japan, with 363 votes, ahead of the Toyota GT 86/Subaru BRZ 318), the BMW 3-series (282) and the Range Rover Evoque (218).

Skyactiv is Mazda's designation for its range of new-generation technologies in petrol (gasoline) and diesel engines, transmissions, as well as a new body and chassis, all aiming at enhancing efficiency by reducing weight and boosting safety and dynamism.

 Dimensions

The dimensions of the new Mazda6 sedan fit amongst the largest models of the D-segment category, with a wheelbase of 2.83 metres / 111.4 inches (much longer than the previous 2.73 metres / 107.4 inches wheelbase), within an overall body length of 4.865m / 191.5 inches (previously 4.76 metres / 187.4 inches), 1.84m width (72.4 inches) and 1.45m height (57.1 inches).

Performance: petrol / diesel - Main engines and specifications

The boot (trunk) volume has also a rather generous 489-litre volume (with the 5 seats up, including the sub-trunk). Load floor length is 1,190mm (46.8 inches) to the 2nd row of seats, and  1,961mm (77.2 inches) to the back of the driver and front passenger seats. 

 Touring

The estate / touring body version, which also seats up to five passengers, comes with a shorter overall length of 4,800mm / 189 inches and a wheelbase of 2,750mm / 108.2 inches, with the same body width but 30mm 1.18 inch higher than an equivalent 4-door version.

The boot (trunk) volume of the estate version has a volume of 522 litres (with the 5 seats up, including the sub-trunk). Load floor length is 1,113mm (43.8 inches) to the 2nd row of seats, and  1,873mm (73.7 inches) to the back of the driver and front passenger seats. 

 Engines

Depending on markets, the new Mazda6 comes with petrol (gasoline) engines displacing 2.0 or  2.5-litres (the latter is mostly for the Japanese and American markets), as well as a 2.2-litre diesel engine available in two output and torque levels. All engines come with front-wheel-drive, six-speed manual or automatic transmissions (more about the petrol engine performance and fuel consumptions - diesel engine performance and fuel consumption).

The 6-speed manual transmission is available  with all  engine models. The six-speed Skyactiv automatic transmission locks-up over most of the range, except during take-off (to make it smoother).

 2.2 D

Based on the Mazda Motors UK figures, the D 2.2-litre engine with direct diesel injection and variable twin turbocharger has a displacement of 2,191cc in four inline cylinders with 16 valves and a low compression ratio (for a diesel) of 14.0 to one.

Thanks to the electronic precision, this low compression ratio allows the use of a lighter aluminium engine block.

In the standard D 2.2-litre version, maximum output is 150 PS (110 kW, 148 bhp) at 4,500 rpm with a maximum torque of 380 Nm (280 lb-ft, 38.7 kg-m) at 2,000 rpm. Specific output comes at 68.5 ps, 67.5 bhp and 50.3 kW per litre (or 1000cc), with a specific torque figure of 173.4 Nm,128 lb-ft and 17.7 kg-m per litre (more). 

In the high power version, maximum output is 175 PS (18.79 kW, 172.6 bhp) at 4,500 rpm with a maximum torque of 420 Nm (310 lb-ft, 42.8 kg-m) at 2,000 rpm. Specific output comes at 80 ps, 78.8 bhp and 58.7 kW per litre (or 1000cc), with a specific torque figure of 191.7 Nm, 141.4 lb-ft and 19.5 kg-m per litre.

 2.5 G

The SKYACTIV-G 2.5 gasoline engine also has four inline cylinders with 16 valves, variable valve timing and direct petrol (gasoline) injection, representing a larger version of the 2.0-litre engine. Available figures indicate a maximum output of 192 PS (141 kW, 189 bhp) at 5700 rpm and maximum torque of 256 Nm (189 lb-ft, 26.1 kg-m) at 3250 rpm.

These figures show a specific output of 76.8 ps per litre or 1000cc (56.4 kW, 75.6 bhp) and a specific torque of 102.4 Nm per 1000cc (75.6 lb-ft, 10.4 kg-m).

 i-ELOOP

In the Japanese market first, most versions are equipped with the Skyactiv technology, with i-stop, Mazda's idling stop system, and i-ELOOP, a new brake energy regeneration system (short for "intelligent Energy Loop") which uses a capacitor to store electricity recovered during deceleration to power the vehicle’s electrical systems, improving fuel economy. All Skyactiv engine-powered Mazda models (starting with the new Mazda6) will be available with i-ELOOP.

Mazda explains that a typical vehicle deceleration phase lasts only about 10 seconds. As the effectiveness of regenerative braking systems to date has been limited by the charging and storage drawbacks of conventional lead-acid starter batteries, Mazda engineers adopted an electric double-layer capacitor (EDLC), which recharges fully in a few seconds. A 12V-25V variable voltage alternator generates the electricity and charges the EDLC; a DC/DC converter then steps down the voltage to power electrical components such as the climate control air-conditioning and audio systems, with any surplus going to the starter battery.

The Japanese brand adds that a full capacitor charge is enough to run the vehicle’s electrical systems for a minute or so, making i-ELOOP a good companion for i-stop, as there is no need to revert to battery power even when Mazda’s idle-stop system has shut the car's engine off. During stop-and-go city driving, charging often resumes before the capacitor is fully discharged and i-ELOOP can therefore produce most if not all of a vehicle’s electricity needs, whereas normally some of the engine’s output is required just to drive the alternator. By freeing up this engine capacity, i-ELOOP increases fuel economy under everyday urban driving conditions.

 i-Activsense

The all-new Mazda6 / Atenza also offers the i-Activsense, which is a set of active safety technologies designed to help avoid accidents. They include cameras and radars to detect obstacles, and systems which automatically apply the brakes in an emergency, sound an alarm if the vehicle drifts out of its lane, or prevent the car from taking off if the driver mistakenly steps on the accelerator instead of the brake.

The i-Activesense safety panoply includes (standard or optional availability is to be checked depending on versions and markets) the following systems:

- A radar assisted cruise control (MRCC, for "Mazda Radar Cruise Control") which allows the driver to keep a safe distance from preceding vehicles at speeds of up to 125mph (201 km/h), by controlling the speed and brakes as needed,

- The Smart Brake Support (SBS) which monitors preceding vehicles at speeds of 10-90mph (16-145 km/h), warning the driver when his/her car gets too close and braking automatically if it detects that an accident is imminent,

- The Smart City Brake Support (SCBS) automatically brakes the vehicle to avoid or reduce the severity of front-end collisions in a 2.5-19mph (4-30 km/h) speed range, complementing Smart Brake Support at lower speeds and in urban environments,

- The Lane Departure Warning System (LDWS) alerts the driver of unintended lane changes,

- A Rear Vehicle Monitoring (RVM) function to detect and warn the driver of cars approaching from behind in adjacent lanes, in the blind spots,

- An Emergency Stop Signal (ESS) which blinks the hazard lights during heavy braking to warn other motorists following behind,

- A High Beam Control system (HBC) to automatically change between high and low beams and avoid impairing the vision of oncoming motorists, and an Adaptive Front-lighting System (AFS), which turns the headlamps to better illuminate curves,

- The Hill Launch Assist (HLA) which controls brake pressure to prevent the vehicle from rolling back during hill starts,

- A standard ABS brakes system with brake assist (it boosts brake pressure in emergencies), EBD (Electronic Brake-force Distribution between the front and rear wheels), DSC (Dynamic Stability Control) and TCS (Traction Control System).

The passive safety equipment of the new Mazda6 / Atenza includes standard front, side and curtain airbags, improved anti-whiplash front seats and a bonnet and body cowl enhanced to better protect pedestrians, especially from head injuries, and a bumper designed to protect pedestrians’ legs in case of an impact.
