The BMW M3 is a high-performance version of the BMW 3 Series. The first iteration of the road car engine produced 195 PS (143 kW) with a catalytic converter and 200 PS (147 kW) without a catalytic converter in September 1989 power was increased to 215 PS (158 kW) with a catalytic converter.
The E30 M3 differed from the rest of the E30 line-up in many ways. The M3, although using the same basic unit-body shell as the standard E30, was equipped with 12 different and unique body panels for the purposes of improving aerodynamics, as well as “box flared” wheel-arches in the front and rear to accommodate a wider track with wider and taller wheels and tyres. The only exterior body panels the standard model 3 Series and the M3 shared were the bonnet, roof panel, sunroof, and door panels.
