2011 Australian Manufacturers' Championship

The increased emphasis on endurance races saw the return of the long-running Sandown 500 event, last run for V8 Supercars in 2007.

Defending Australian Production Car Champion, Western Australian Mitsubishi Lancer Evo driver Stuart Kostera dominated the series, winning six races and four rounds with a second position in the final race of the year at Eastern Creek.

The result was so impressive, Kostera's part-time co-driver New Zealander Ian Tulloch finished second in the championship.
