BMW 3 Series (E30) - Wikipedia, the free encyclopedia Page 1 of 12 BMW 3 Series (E30) From Wikipedia, the free encyclopedia The BMW E30 was a compact executive car BMW 3-Series (E30) produced by BMW. It was the successor of the BMW E21 in 1983 and was replaced by the BMW E36 in 1990. BMW continued to produce the cabriolet (convertible) E30 well into 1993. The Touring remained in production until 1994 when the E36 touring replaced it. The M3 cabriolet was never officially offered for sale in North America; it was offered only for the European market. The BMW M3 was first introduced on the E30 Manufacturer BMW platform. A widened version of the E30 front Production 1983–1994 suspension and the drivetrain from the E30 325i were used in the BMW Z1 roadster. Predecessor BMW E21 Successor BMW E36 The E30 3-Series was produced in four body styles, a four door saloon, a two door saloon, a five door Body style 2-door coupé estate (marketed as the "touring"), and a two door 2-door convertible convertible. A Baur cabrio was also available. The 4-door saloon 325ix was produced from 1988 to 1991, and 5-door estate featured all-wheel drive. It was available as a two- door (coupé) or a four-door (sedan) and as touring. Layout Front engine, rear-wheel drive / all-wheel The BMW M3 utilised a widened and heavily drive redesigned and restyled variation of the 2 door body style. The M3 shares few parts with other E30 Engine I4, 1.6 - 1.8 L (66 - 100 kW) models, however many M3 parts can be used on the I6, 2.0 - 2.7 L (92 - 126 kW) other body styles and are interchangeable offering Transmission 3-speed automatic the consumer an OEM "upgrade". These parts 4-speed automatic consist of control arms, control arm bushings, steering racks, etc. 4-speed manual 5-speed manual The primary distinctive feature of the BMW E30 Wheelbase 2,570 mm (101.2 in) models produced for the North American market in 1984-1987 are the elongated front/rear aluminum Length 1988-89 Sedan & Wagon: 4,450 mm bumpers. These bumpers are commonly known as (175.2 in) "diving boards." In 1988, the anodized aluminum 1988-89 Convertible: 4,460 mm bumpers were shortened by revising the (175.6 in) cover/fillers and shortening the shocks. In 1989 the 1990-91 Sedan & Wagon: 4,326 mm aluminum bumpers were replaced with shorter body -color plastic bumpers. (170.3 in) 1990-93 Convertible: 4,323 mm The cars were powered by a range of inline 4 (170.2 in) cylinder (BMW M10 , BMW M40 , & BMW M42) and inline 6 cylinder (BMW M20 and BMW M21) Width Sedan & Wagon: 1,646 mm (64.8 in) engines, with both petrol and diesel power. Torque 2 door Saloon: 1,661 mm (65.4 in) output for the engines ranges from 140 N·m Height (100 lb·ft) torque for the 1.8 L (1766 cc) 4 cylinder engine, to 230 N·m (170 lb·ft) torque from the http://en.wikipedia.org/wiki/BMW_3_Series_(E30) 7/ 22/ 2011 BMW 3 Series (E30) - Wikipedia, the free encyclopedia Page 2 of 12 2.7 L (2693 cc) 6 cylinder petrol engine. The E30 Sedan & Wagon: 1,379 mm (54.3 in) BMW M3 was fitted with a high-revving 4-cylinder Convertible: 1,369 mm (53.9 in) engine (BMW S14) which produced 175 kW Coupe: 1,400 mm (55.1 in) (238 PS; 235 hp) in its final European-only citation needed iteration.

The 316 used a 1766 cc M10 fed by a carburetor and producing only 66 kW (90 PS; 89 hp), but this allowed BMW to offer a 1990–1991 BMW 318is (E30) 2-door cheap, entry-level car in the sedan (Australia) BMW E30 325i Engine range. The 318i had the same M10 engine, but with Jetronic fuel injection, pushing power to 77 kW (105 PS; 103 hp) and improving fuel economy. Finally, the 320i (2.0 L M20 with 92 kW (125 PS; 123 hp)) and 323i (2.3 L M20 with 105 kW (143 PS; 141 hp)) completed the range. Later, in 1985, a 2.5 L version of the M20 boosted the power of the top model to 125 kW (170 PS; 168 hp), replacing the old 323i. The 325ix (All 1988–1990 BMW 320i (E30) Wheel Drive model) had a 2.5 liter M20 with 125 kW (170 PS; convertible (Australia) 168 hp) (same as the 325i). Europe and North America received an economy version called the 325e (the e stands for the Greek letter eta, signifying efficiency). Strangely enough, the engine was the largest available in the chassis, aside from the rare South African version which was available with the 3.3 L M30. The 2.7 L had a longer stroke than the 2.5 L, with a more restrictive head, four cam bearings instead of seven (less internal friction), and softer valve springs. This resulted in 90 kW (122 PS; 121 hp). In 1987, the E30 was revised. The revision http://en.wikipedia.org/wiki/BMW_3_Series_(E30) 7/ 22/ 2011 BMW 3 Series (E30) - Wikipedia, the free encyclopedia Page 3 of 12 contained two significant changes in the engine department. First, the M20 straight-6 engines changed from Bosch Jetronic to Bosch Motronic. This boosted the 320i to 95 kW (129 PS; 127 hp) and the 325i to 126 kW (171 PS; 169 hp), all the while improving the economy. The M10 was replaced by the new, belt-driven cam M40 which also incorporated Motronic injection. The new 318i now had 85 kW (116 PS; 114 hp) and was noticeably smoother than the old version. A new engine had been developed, a chain-driven cam 4 cylinder M42 1.8 L DOHC 16 V engine creating the 318is in 1989. This is the most modern engine built to the E30 (this engine has been E30 Touring' later used in early 318i E36s). The 316 was replaced by a 316i, which used a 1600 cc version of the M40, producing 75 kW (102 PS; 101 hp). Not quite as torquey as the 66 kW (90 PS; 89 hp) 1766 cc M10 it replaced, it nevertheless offered superior performance. In some markets, like South Africa, the old M10-powered 316 continued a lot longer, gaining the new bumpers of the other models. In South Africa, The 316i was released in 1991. Drivetrain In total, seven transmission were available for the various models of the E30: four manuals, and three automatics. A 4-speed manual was available for the 316 and 318i (Getrag 220). The 316, 318i, and 320i also had the option of a common 5-speed manual (Getrag 240), while the 323i and 325i had a different manual (Getrag 260), and in addition, the 323i had a sports manual as an option(??). The transmissions for the 316 and 318i featured synchromesh on forward gears only, while the 320i and 323i, both with standard and sports transmissions, had synchromesh on reverse as well. Both automatic transmissions were manufactured by ZF - they were the 3-speed 3 HP 22, which was available on the M10 316 and 318i models, and the 4-speed 4 HP 22, which was available on the 320i, 323i, 324td, 325, 325i and 325e models, as well as M40 and M42 316i and 318i.

The 316 and 318i shared a differential, as did the 320i and 323i, with the standard transmission. 323i models with sports transmissions had a different differential. The 325i received its own ratio, as did the 325e. The various M3s had special ratios as well. http://en.wikipedia.org/wiki/BMW_3_Series_(E30) 7/ 22/ 2011 BMW 3 Series (E30) - Wikipedia, the free encyclopedia Page 4 of 12 Differential Gear Ratios and Types: BMW E30 M3 BMW 320 E30 Cabriolet 1989 BMW 318i Baur TC2 http://en.wikipedia.org/wiki/BMW_3_Series_(E30) 7/ 22/ 2011 BMW 3 Series (E30) - Wikipedia, the free encyclopedia Page 5 of 12 BMW 325e Sedan (US) http://en.wikipedia.org/wiki/BMW_3_Series_(E30) 7/ 22/ 2011 BMW 3 Series (E30) - Wikipedia, the free encyclopedia Page 6 of 12 http://en.wikipedia.org/wiki/BMW_3_Series_(E30) 7/ 22/ 2011 BMW 3 Series (E30) - Wikipedia, the free encyclopedia Page 7 of 12 case model(s) ratio(s) type(s) size 316 before 9/84 3.64 small open 316 after 9/84 3.91 small open 316i M10 3.91, 4.10 small open 316i M40 4.27, 4.45 small open 318i M10 3.64, 3.91, 4.10 small open 318i M40 2- and 4- 4.10, 4.45 small open doors 318i M40 convertible and 4.27, 4.45 small open touring open (USA Spec had an 318is 4.10 small optional 4.10 small case LSD) 320i before 9/85 3.46 small open 320i 9/85 to 9/87 3.64, 3.91 small open 320i after 9/87 4.10 small open 320i convertible 4.27, 4.45 small open and touring 323i before 9/84 3.23 medium open 323i after 9/84 3.46 medium open 324d 3.45 small open 324td 3.25 medium open standard - open 3.46, 3.73, 3.91, 325i before 9/86 medium sports - mechanical 4.10 limited-slip standard - open 3.64, 3.73, 3.91, 325i after 9/86 medium sports - mechanical 4.10 limited-slip standard - open 325i convertible 3.46, 3.91 medium sports - mechanical before 9/86 limited-slip standard - open 325i convertible 3.64, 3.91, 4.10 medium sports - mechanical after 9/86 (USA SPEC) limited-slip http://en.wikipedia.org/wiki/BMW_3_Series_(E30) 7/ 22/ 2011 BMW 3 Series (E30) - Wikipedia, the free encyclopedia Page 8 of 12 325i touring 3.91 medium open 3.64, 3.73, 3.91, 325ix 2- and 4- open, all viscous, 10- 4.10(US SPEC medium doors 100% limited-slip
