Mazda has just announced that its brand new 2011 Mazda BT-50 utility will make its first appearance during next month’s Australian International Motor Show (AIMS) in Sydney.

Mazda released the above image as a teaser sketch of the new BT-50, with the striking styling inspired by Mazda’s current passenger-car range.

The model was designed in partnership with Ford and its sister model the Ranger. The BT-50 will be both wider and longer than the current model, providing greater stability thanks to its wider track. Interior space will also benefit, with the rear seats likely to prove more spacious.

Mazda has revealed little in the way of technical details for the new BT-50, so far, although the new model is sure to be offered in dual-cab and king-cab form. The two companies recently announced plans to invest US$350 million in the AutoAlliance (AAT) plant in Thailand which will handle production of the BT-50.

Scheduled to launch during Mazda’s press conference on October 15, the new BT-50 will be on view to the public afterwards.
