2012 Australian Manufacturers' Championship
The 2012 Australian Manufacturers' Championship was a CAMS sanctioned Australian motor racing championship for modified production touring cars. The Manufacturers Championship was determined by a series pointscore for the manufacturers of the competing vehicles although the manufacturers themselves did not directly compete. The series also incorporated the 2012 Australian Production Car Championship, the 2012 Australian Production Car Endurance Championship and the 2012 Australian Endurance Championship, each of which was a drivers' title.

The 2012 Australian Manufacturers' Championship was the 27th manufacturers title to be awarded by CAMS and the 18th to be contested under the Australian Manufacturers' Championship name.

Class structure
Cars competing in the following seven classes:
 Class A : Extreme Performance
 Class B : High Performance
 Class C : Performance Touring
 Class D : Production Touring
 Class E : Compact Touring
 Class F : Hybrid/Alternative Energy
 Class I : Invitational (former Mini Challenge cars – not eligible for championship points)

There was little change from the 2011 class structure, although one new class, Class F for Hybrid/Alternative Energy vehicles was included. Despite its name however, the only eligible vehicles were existing diesel powered cars which had been moved from other classes into the new class.

Calendar
The championship was contested over a five-round series.

Points system
Each manufacturer could score class points towards the Australian Manufacturers' Championship title from the two highest placed automobiles of its make, in any class (excluding Class I). The title was awarded to the manufacturer that scores the highest total number of class points over all rounds of the championship. 
 In rounds with one scheduled race, points were awarded to manufacturers on a 120–90–72–60–54–48–42–36–30–24–18–12–6 basis for the first thirteen places in each class with 3 points for other finishers.
 In rounds with two scheduled races, points were awarded to manufacturers on a 60–45–36–30–27–24–21–18–15–12–9–6–3 basis for the first thirteen places in each class in each race with 2 points for other finishers.

Points towards the Australian Production Car Championship outright title were awarded to drivers based on outright finishing positions attained in each race. Points were awarded using the same two scales as used for the Australian Manufacturers' Championship with the addition of two points for the driver setting the fastest qualifying lap in each class at each round.

Whilst Jim Pollicina and Ryan Simpson were the winners of Round 2, a 60-point penalty was applied to the two drivers at that round. The 2012 Australian Endurance Championship was therefore awarded to Stuart Kostera and Ian Tulloch, who placed second at Round 2.
