the 900c, also produced regular 900s, a total of 238,898 examples. The plant in Arlöv (now closed), near Malmö, also produced some 900s. For 1981 all models except for the GL three-door received a considerable boost in equipment, as well as broader side trims, larger luggage compartments and fuel tanks. The spare tire was moved to underneath the floor, rather than standing upright in the luggage compartment. A big change for 1982 was the introduction of Saab's Automatic Performance Control (APC), a.k.a. boost controller for the Turbo models. The APC employed a knock sensor, allowing the engine to use different grades of gasoline without engine damage. Another new feature that year was the introduction of central locking doors (on the GLE and Turbo). The long-wheelbase 900 CD was also introduced. Asbestos-free brakes were introduced in 1983, an industry first. The front pads were semi-metallic while the rears were made from silica. The GLE model gained a new central console, while the decor strips on the bumpers of all models were made wider (necessitating wider trim pieces on the flanks as well). A new luxury package was made available on Turbo cars. Model year 1984 saw the introduction of the 16-valve DOHC B202 engine in Europe. With a turbocharger and intercooler, it could produce 175 hp/129 kW in the Turbo 16 model (less for catalyst-equipped engines). The Turbo 16 Aero [designated SPG, Special Performance Group in North American Markets] had a body kit allowing the car to reach 210 km/h (130 mph). A different grille and three-spoke steering wheel appeared across all models. The connection between the side strips and the bumpers was changed, Turbo hatchbacks received a black trim piece between the taillights, and the GLi began replacing the twin-carburetted GLs. At the 1983 Frankfurt Motor Show a two-door sedan was shown; it went on sale in January 1984, initially only as a GLi. The two-door sedan was only ever built at the Valmet plant in Finland. The dual-carburettor model (and "GLs" nomenclature) was gone for 1985. Now, the base 900 had the single-carburettor engine, while the 900i added fuel injection. Two turbocharged models were offered: The 900 Turbo had the 8-valve engine, while the Turbo 16 (also Aero) had the 16-valve intercooled unit. Wheel trims (naturally aspirated cars) and alloys (turbos) were redesigned, and the Turbos also received chromed grilles. The 8-valve turbo received an intercooler for 1986, bringing
