GM's Australian division Holden has been busy preparing for the 2011 Australian International Motor Show, which goes from July 1st to 10th in Melbourne. Among the cars set to debut at the show are a bunch of Chevrolet Cruze's and Sonic's (named Barina) that have been rebadged as Holdens to suit the Aussie market next year. In addition to the Cruze and Sonic, Holden will unveil the Colorado 4x4 concept pickup truck, which we know as the Chevrolet Colorado Rally Concept from the Buenos Aires Motor Show.

Holden will also be updating its flagship Commodore series with the addition of an E85 capable V6 engine option. The E85 flex-fuel 3.6-liter SIDI V6 will be giving the Commodore its power under the hood and at the same time making the Commodore a more fuel efficient car. The 2011 Australian International Motor Show will feature more than 50 exotic cars including such supercars as the V12 Lamborghini Aventador LP700-4 (also Bruce Wayne's new ride), the Audi R8 GT Spyder (only 333 units in the world), the Bentley Continental GT and Masserati's fastest road car, the MC Stradale.

The first Melbourne Motor Show (later renamed) was held back in 1925 at Melbourne's iconic Royal Exhibition Building and later relocated to the Melbourne Convention and Exhibition Center in 1996. It has since been home to many concept and exotic cars ever since.
