Welcome to BMW E30`s for sale

The BMW E30 is the second generation of BMW 3 Series, which was produced from 1982 to 1994. The initial models used the coupe (two-door sedan) body style, with four-door sedan models introduced in 1983, convertibles introduced in 1985 and wagon/estate models (marketed as "Touring") introduced in 1987.

The E30 was the first 3 Series to be available in wagon and four-door sedan body styles. It was also the first 3 Series to have a diesel engine option. All-wheel drive was introduced to the 3 Series range with the 325iX model. The BMW Z1 roadster was based on the E30 platform.

The E36 replaced the E30 coupe models in 1990. Sedan production concluded on April 30, 1991 at Regensburg, with a white example. Other variants were phased out gradually, until the final E30 model, a Touring, was produced in 1994.

The first BMW M3 was built on the E30 platform. The E30 M3 is powered by the high-revving BMW S14 four-cylinder petrol engine, which produced 175 kW (235 hp) in its final European-only iteration.

Development & Launch

Development of the E30 3 Series began in July 1976, with styling being developed under chief designer Claus Luthe. In 1978, the final design was approved, with design freeze (cubing process) being completed in 1979. The car was released at the end November 1982.

Externally, the E30's appearance is very similar to twin headlight versions of its E21 predecessor, however there are various detail changes in styling to the E30. Major differences to the E21 include the interior and a revised suspension, the latter to reduce the oversteer for which the E21 was criticised.Like the E21, a Baur convertible was available.

Engines

Initially, the E30 models used the M10 straight-four and the M20 straight-six engines, like its E21 predecessor. Over the production run, the M10 was replaced with the M40 and M42, the M20 received various upgrades and the S14 engine was introduced in the M3.

A six-cylinder diesel was also introduced later, in both naturally aspirated and turbocharged forms.

Four-cylinder

At the launch of the E30 range in 1982, the 316 used a 1766 cc M10 fed by a carburettor and producing 66 kW (89 hp). The 318i had the same M10 engine, but with Jetronic  fuel injection, pushing power to 77 kW (103 hp)  while also improving fuel economy.

The 1987 Series 2 update introduced a new four-cylinder engine: the M40, which used Motronic fuel-injection. In the 318i, a 1,796 cc (109.6 cu in) version of the M40 was used. The 316i model replaced the 316, using a 1,596 cc (97.4 cu in) version of the M40.

The 318iS coupe was released in 1989, using the new M42 engine. This is the most modern engine available in the E30 range, incorporating DOHC, the updated Bosch Motronic 1.3, hydraulic valve adjusters and coil-on-plug ignition. In some markets, the M42 engine was used in the 318i (sedan) and 318iC (convertible) models, instead of the M40.

The M3 is powered by the S14 engine, a high-revving motorsport engine with a cylinder head derived from the M88 six-cylinder engine.

Six-cylinder

Petrol

 
BMW E30 325i engine

At the launch of the E30 range, the six-cylinder models consisted of the 320i, which had a 2.0 L (120 cu in) M20 engine producing 92 kW (123 hp), and the 323i, with a2.3 L (140 cu in) M20 making 102 kW (137 hp),both using Bosch L-Jetronic fuel injection. These models were not sold in North America, presumably for emissions reasons. In 1985, the 2.3 L engine was replaced with a 2.5 L version of the M20, which produced 126 kW (169 hp) and used Bosch Motronic fuel injection. This engine was available in the 325i variants, including the all-wheel drive 325iX.

An economy version called the 325e was released as a lower revving, more fuel efficient engine. The e is an abbreviation for eta, which is used to represent the thermal efficiency of a heat engine. To maximise low-rev torque, the engine was the largest available in an E30, aside from the South Africa-only 333i model. The 2.7 L (160 cu in) engine had a longer stroke than the 2.5 L, with a more restrictive head, four cam bearings instead of seven (less internal friction), and single valve springs (instead of the dual valve springs used by the 2.5 L engine). This resulted in 90 kW (120 hp) at 4250 rpm and, more importantly, 240 N⋅m (180 lb⋅ft) at 3250 rpm  (without catalytic converter) Peak torque for the 2.5 L (150 cu in) engine is 215 N⋅m (159 lb⋅ft) at 4000&nbp;rpm).

The 1987 Series 2 update boosted the 320i to 95 kW (127 hp) and the 325i to 126 kW (169 hp), and improved fuel economy.

Diesel

 
BMW M21 diesel engine

In 1983 the 324td was unveiled at the IAA, Germany. The M21 diesel straight-six engine was turbocharged using a Garrett turbocharger, but without intercooler. The engine has a capacity of 2,443 cc (149 cu in) and uses mechanical (indirect) fuel injection.

In 1985 BMW introduced the 324d, a naturally aspirated version of the same M21 engine, which was popular in countries with a high motor vehicle tax.

In 1987 an electronically controlled fuel pump was used  which increased the torque output by 10 N⋅m (7 lb⋅ft). The updated engine has a smaller turbocharger, decreasing turbo lag.
