New tyres with less rolling resistance have been introduced as part of the economy drive. These tyres sit on 18-inch or 20-inch wheels (depending on model) and are to a new design. Just as importantly, they are lighter than before, something that should improve ride comfort.

Trimming fuel consumption of the Mazda CX-9’s 3.7-litre V6 engine by almost a litre every hundred kilometres not only makes life easier on the owner’s bank account, but also cuts emissions of CO2.

We have yet to carry out a road test on the latest Mazda CX-9, but will do so as soon as possible and report back on our findings.

Other than the mechanical changes and the sportier looking alloy wheels the 2011 Mazda CX-9 remains as before. The temptation to give the model a facelift has been resisted in these tough economic times, Mazda relying instead on making the CX-9 better in the out of sight areas.

Though it’s Japanese, the design of the Mazda CX-9 is oriented towards the American SUV market. So it’s a large vehicle with good interior space and plenty of grunt from its big 3.7-litre V6 engine. Features that will be appreciated by Australian owners.

There's room for seven adults without them being overly cramped, though four adults and three children is more realistic. The centre seats can slide back and forward to let you juggle the amount of legroom available in this seat and the third row seats. With the centre seat in its rearmost position there's almost limo-like legroom for its occupants.

The third row of seats fold flat very simply to give a useful increase in luggage space, but even with the seats in use there's still space for a couple of fair-sized suitcases.

Though it’s similar in overall dimensions to large 4WDs like the Nissan Patrol and Toyota LandCruiser the Mazda looks smaller and less intimidating. This is an illusion to some extent and parking it in tight spaces can be quite a feat at times. To its credit, this big Mazda has a good turning circle for its class and this can be a real help.

Changes to the suspension of the American model give Australian versions of the Mazda CX-9 a more dynamic feel and firmer steering. It’s still relatively soft, though steering feel isn’t bad for a big people mover and there's little understeer until it’s going quite hard at bends.

Ride comfort is good and is enhanced by excellent NVH (Noise, Vibration and Harshness) insulation at highway speeds.

Mazda Australia has been pushing safety features hard for several years now. So the CX-9 has electronic stability control and rollover protection to help prevent crashes. As well as six airbags should one become inevitable.

A reversing camera is a good feature in a large vehicle with limited rearwards visions.

The revised Mazda CX-9 is offered in three grades and is in on sale now. Prices remain unchanged, ranging from $50,015 for the CX-9 Classic to $63,133 for the Grand Touring. These prices do not include dealer or government charges.
