A When BMW introduced the M3 of the E30 series in 1986, initially only the production of a homologation series of 5000 pieces was planned. In fact, almost 18,000 copies were then sold. The successors from the E36 and E46 series were even more successful with 71,000 and 85,000 units. It wasn't until 2013 that sales fell again - to around 66,000 units.
The first BMW M3 was presented in 1985 at the International Motor Show in Frankfurt. Production took place at BMW Motorsport GmbH. Over the years, various special series appeared, including the Evolution II models with 220 hp and the Sport Evolution with a 2.5 liter engine and 238 hp, which was offered from 1990. Production ended in 1991, the successor was the E36.
In addition to wider fenders, spoilers and sills, the M3 has other differences compared to other E30s. This includes a glued front and rear window; Since the latter is also flatter, the C-pillar is a little wider. The trunk lid, now made of GRP, is also set higher. Like all other E30 convertibles, the open M3, which was also available from 1988, has a trunk lid made of sheet metal.
The M3 is based on the normal E30, but the body changes have improved aerodynamics and significantly reduced lift forces. The wheelbase of the M3 is slightly shorter than that of other E30s. The rims have five instead of four screw holes, the suspension and damping have been designed to be much tighter. The M3 has four internally ventilated disc brakes and improved power assistance for steering and braking as well as a five-speed sports transmission with first gear at the rear left, as well as a limited-slip differential.
The S14 unit from BMW goes back to the four-cylinder M10, which was introduced at the beginning of the 1960s and also used extremely successfully in sport. For the M3, the cast iron engine was fitted with a four-valve head. This was derived from the six-cylinder M88, which was used in the 635 CSi, among other things.
The M3 exudes pure dynamism. The engine revs up willingly and grabs a lot at every speed. With its balanced chassis and direct steering, the over-threesome is the purest corner robber, traction problems are alien to it.
The BMW E30 M3 as a classic
The successor models benefited from the reputation of the predecessor, but they were no longer as wonderfully simple and straightforward as the first M3. Today he is wanted and prices are rising; Those who have a well-preserved copy can hardly be found back.
