- BMW E30The primary distinctive feature of the BMW E30 models produced for the North American market in 1984-1987 are the elongated front/rear aluminum bumpers. These bumpers are commonly known as "diving boards." In 1988, the anodized aluminum bumpers were shortened by revising the cover/fillers and shortening the shocks. In 1989 the aluminum bumpers were replaced with shorter body-color plastic bumpers.
The cars were powered by a range of inline 4 cylinder (BMW M10 , BMW M40 , & BMW M42) and inline 6 cylinder (BMW M20 and BMW M21) engines, with both petrol and diesel power. Torque output for the engines ranges from 140 N·m (100 lb·ft) torque for the 1.8 L (1766 cc) 4 cylinder engine, to 230 N·m (170 lb·ft) torque from the 2.7 L (2693 cc) 6 cylinder petrol engine. The E30 BMW M3 was fitted with a high-revving 4-cylinder engine (BMW S14) which produced 175 kW (238 PS; 235 hp) in its final European-only iteration.
