The BMW E21 is the first generation of the BMW 3 Series, which was produced from June 1975 to 1983and replaced the BMW 02 Series. Initial models were produced in a two-door sedan body style with four-cylinder petrol engines. Fuel-injected engines were introduced in late 1975 and 6-cylinder engines wFor the 1980 model year, the four-cylinder models were upgraded: the 1.8 L carburetted M10 unit was revised to produce 66 kW (89 hp) and entered the market in the updated 316, while a fuel-injected version of the 1.8 L M10 was introduced in the 318i model (which replaced the carburetted 318 as the mid-range model). This fuel-injected 1.8 L M10 was also sold in Sweden with 320i badging (with a higher level of standard equipment to distinguish it from the 318i), because the 320/6 was never certified for sale there.
