A new-look Mazda CX-9 has been revealed, with the Japanese brand announcing the redesigned seven-seater SUV will make its global debut at the 2012 Sydney motor show.

The styling of the big SUV has been brought into line with the rest of the Mazda family and isn't a new-generation model like the smaller Mazda CX-5 released earlier in 2012. Design changes are focused on the front and rear ends, with the headlights and grille familiar from the CX-5.

The revised Mazda CX-9 remains on the same platform as the original launched in 2007 and shared with the Ford Edge. It also carries over the same 3.7-litre V6 petrol engine that produces 204kW of power and 366Nm of torque, mated to the same six-speed auto.

There are no SkyActiv technologies featured on the revised Mazda CX-9, such as the lighter-weight chassis or i-Eloop brake energy regeneration system found on all-new models such as the Mazda CX-5 and Mazda6 that are aimed at improving fuel efficiency.

The result is no change in consumption for the CX-9, which is currently 11.0L/100km for the front-wheel-drive version and 11.3L/100km for the model equipped with all-wheel drive.

"The CX-9 is our flagship and while not a volume seller it does very well for our brand," says Mazda Australia spokesman Steve Maciver. "It's well regarded for its driving dynamics. We have said that SkyActiv technologies will be adopted across the entire Mazda range but there's no announcement for this [CX-9] yet."

The update also brings some upgrades to the CX-9's infotainment system and there are additional active safety features including lane departure warning, forward obstruction warning and high beam control.

Mazda says it has sold more than 210,000 CX-9s in 74 countries since the SUV first hit the road in 2007.
