Subaru is the automobile manufacturing division of Japanese transportation conglomerate Subaru Corporation. It is the twenty-second largest automaker by production worldwide in 2012. Subaru cars are known for their use of a boxer engine layout in most vehicles above 1500 cc. The Symmetrical All Wheel Drive drive-train layout was introduced in 1972. The flat/boxer engine and all-wheel-drive became standard equipment for mid-size and smaller cars in most international markets by 1996, and is now standard in most North American market Subaru vehicles. The lone exception is the BRZ, introduced in 2012 via a partnership with Toyota, which uses the boxer engine but instead uses a rear-wheel-drive structure. Subaru also offers turbocharged versions of their passenger cars. In Western markets, the Subaru brand has traditionally been popular among a dedicated core of buyers. Marketing is targeted towards specific niches centered on those who desire the company's signature drive train engine, all-wheel/rough-road capabilities or affordable sports car markets.
