The mid-sized sedan model rides on a 2,830mm (111.4 inches) long wheelbase that is 105mm (4.1 inches) longer than previous '6'. On the outside, the saloon measures 4,865mm (191.6 inches) long, 1,840mm (72.4 inches) wide and 1,450mm (57.1 inches) tall.
Compared to the previous model, the front wheel has been moved forward by 100mm in relation to the A-pillar resulting in reduced front overhang, while the rear deck is also shorter.
According to Mazda, the new 6 offers 20mm (0.8 inches) more shoulder room for the front passengers. At the back, there is 43mm (1.7 inches) greater knee clearance, 37mm more legroom (1.45 inches), while the length of the rear seat cushion has increased by 20mm (0.8 inches) and the seat back height by 33mm (1.3 inches). Furthermore, the rear centre arm rest has been enlarged by 60mm (2.6 inches).
The trunk, which has a 32mm wider opening than on the previous model for easier loading, has a cargo capacity of 483 liters.
According to Mazda, the new SKYACTIV-Body structure makes wider use of ultra-high tensile steel reducing weight, while at the same time improving torsional rigidity by about 30 percent
The car employs MacPherson struts up front and a rear multi-link suspension while there's also a new column-type electric power assistance. The Japanese automaker claims that the new Mazda6 will be a driver's car.
"In developing the third-generation Mazda6, we pursued Mazda’s intrinsic core value: ‘driving pleasure’," says Hiroshi Kajiyama, the new Mazda6 programme manager.
"We wanted to create a car that reacts and behaves exactly as you expect it to. Part of this involved carefully crafting those parts of the car which you often touch to feel as though they are an extension of your own body."
At least in Russia, the 2014 Mazda6 will launch with an initial choice of two new four-cylinder gasoline engines, the SKYACTIVE-G 2.0-liter that generates 148hp (150PS) at 6,000rpm and 210Nm (155 lb-ft) at 4,000rpm and the SKYACTIVE-G 2.5-liter delivering 189hp (192PS) at 5,700rpm and 256Nm (189 lb-ft) at 3,250rpm.
Both powerplants will be offered with 6-speed manual or 6-speed automatic transmissions and a standard i-stop idling stop system.
The 2.5-liter unit will also be the first Mazda engine to employ the brand's new i-ELOOP brake energy regeneration system that begins charging a capacitor the moment the driver takes his foot off the accelerator. The electricity stored is used to power electric components throughout the car instead of the engine thus resulting in further improvements in fuel economy.
The European specification version of the Mazda6 sedan as well as the Station Wagon model will premiere at the Paris Motor Show in late September, with more details about the powertrain choices that will include a diesel engine to be announced later.
Mazda's Honda Accord and Ford Fusion / Mondeo rival will be introduced to global markets starting in late 2012.
