2014 Mazda3 Sedan unveiled

Last month Mazda released details of its all-new Mazda3 hatchback for 2014. Now, we get a first look at the fastback sedan body style that will join it when both arrive in Canadian Mazda stores this fall.

Both models join the Mazda CX-5 CUV and the all-new Mazda6 in adopting the full range of Mazda's SkyActiv technologies, as well as the company's KODO Soul of Motion design language.

Lower and wider than the current model, the sedan incorporates a cab-rearward design. Its raked profile, rising towards the rear, is highlighted by boldly flared fenders and big alloy wheels at each corner.

The sedan shares the hatchback's 2,700-mm wheelbase – 60 mm longer than that of the current model – which allowed designers to shorten the front and rear overhangs, creating more space for the engine and improving crash safety, according to Mazda.Both body styles are 40 mm wider and 15 mm lower than the current model.

The sedan's different roof, rear window, rear quarter and decklid design extend its overall length by 120 mm to 4,580mm – compared to 4,460 mm for the hatchback.

Both models feature rear-seat backrests that fold almost flat and the sedan’s trunk opening width is increased by 100 mm, to 1,102 mm, increasing access to its 419-litre trunk capacity.

Both also boast improved aerodynamics that are now among the best on the market, with Cd (Coefficient of Drag) values of 0.258 for the sedan and 0.275 for the hatchback.

Despite performance-enhancing changes that normally add weight – such as bigger brakes and bigger wheels – the all-new Mazda3 is lighter than the current model and among the lightest C-segment cars.

The combination of low drag, low weight and efficient SkyActiv engines and transmissions is expected to result in exceptionally low fuel-consumption figures when the official ratings are released.
