Interior (1992-1995 530i)

The BMW E34 is the third generation of the BMW 5 Series, which was produced from the 2nd of November 1987 until June 1996.[8][9] Initially launched as a sedan, the E34 also saw a "Touring" wagon (estate) body style in 1990, a first for the 5 Series. BMW replaced the E34 with the E39 in December 1995, although E34 Touring models remained in production until June 1996.

Other firsts include the first all-wheel drive 5 Series with the 525iX, and the first V8 in a 5 Series. The E34 also saw the introduction of stability control (ASC), traction control (ASC+T) a 6-speed manual transmission and adjustable damping (EDC) to the 5 Series range.

There was an unusually large range of engines fitted over its lifetime as nine different engine families were used. These consisted of four-cylinder, straight-six and V8 engines.

The E34 M5 is powered by the S38 straight-six engine and was produced in sedan and wagon body styles.

Development and production[edit]

Development ran from July 1981 to early 1987, with the initial design proposal penned by Ercole Spada in 1982.[10] Under the guidance of chief designer Claus Luthe, BMW based much of the design on the E32 7 Series. Following Spada's departure from BMW and styling approval in 1983, J Mays finalized the design for production in mid-1985. In December 1987, the E34 sedan was unveiled to global press.[11][12] Special attention was paid to aerodynamics, with the E34 having a drag coefficient of 0.30.[13]

Production of the E34 commenced on November 2, 1987 for the 535i, with 535i market launch being in January 1988 and other variants following a staggered launch. 520i and 530i production began in January 1988, for March 1988 market launch. Production of the 525i began in February 1988, being launched to market in April 1988, with the 524td entering production in March 1988 for May 1988 introduction. Touring production began in July 1992, after presentation at IAA 1991. Production ended for the sedan in December 1995 and Touring in June 1996, with 1,333,412 units being built in total.[14][15]

Body styles[edit]

Models[edit]

518i[edit]

The base model, available only in Europe[16] with a total of 53,248 units produced, was initially powered by the four-cylinder M40 engine, which was replaced by the M43 in 1994. The 518i was available in sedan or wagon body styles, but with only a 5-speed manual for the transmission.[17]

520i[edit]

M50 engine- used in later 520i/525i models


The lowest six-cylinder model and the base model in some countries, the 520i was the second most popular E34 model globally, with 426,971 units produced.[18] Initial production of the 520i started in January 1988, using the single-cam M20 engine. In 1990 the M20 was replaced by the twin-cam M50 engine, which was updated to the M50TU in September 1992 with the introduction of VANOS (variable valve timing). The M50-powered 520i was the most popular E34 variant sold in Europe.

525tds[edit]

The tds was introduced in 1991 using M51 turbocharged inline six-cylinder diesel engine. Available in both sedan and wagon body styles

525i[edit]

A mid-range model in most regions (except North America), the six-cylinder 525i was the most popular E34 model globally, with 434,549 units produced.[18] Like the 520i, the 525i was initially powered by the M20 engine, which was later updated to the M50 and M50TU engines.

525iX[edit]

The 525iX was the first all-wheel drive 5 Series, and the only all-wheel drive model in the E34 range. Powered by the M50 engine and available in both sedan and wagon body styles, it saw a total of only 9,366 units.[18] The centre differential normally would divide 36% torque to the front axle and 64% to the rear axle, but could adjust the ratio according to driving conditions in case one of the wheels started to slip.[citation needed] Unique to the 525iX was the use of a rack and pinion steering system.

530i[edit]

There are two versions of the 530i: a six-cylinder model produced from 1988 to 1990, and a V8 model produced from 1992 to 1995. In total 57,570 units were produced. The earlier model, powered by the M30, was not sold in North America. The V8 version, which replaced the six-cylinder 535i in the lineup, was powered by the new M60 engine and was available in sedan and wagon body styles. Transmission choices for the V8 version were a 5-speed manual and a 5-speed automatic.[16] Initially, the V8 models were differentiated from other models by the wide grill; in 1994 the wide grill became available on other models.

535i[edit]

M30 engine- used in the 535i

Powered the six-cylinder M30B35 and only available as a sedan, the 535i saw a total of 97,679 units produced,[18] which includes the Alpina B10 (BiTurbo, 3.5) models. The 535i was replaced by the V8 engined 530i and 540i models in 1993.

Despite the 535i designation and '3.5' casting on the intake manifold, the M30 6-cylinder engine found in the E34 535i was actually 3.4 litres (207 cu in).

540i[edit]

In 1992, the 540i model was added to the top of the 5 Series lineup, powered by the M60 V8 engine and available in both sedan and wagon body styles (the latter not in US). Transmission options were a 6-speed manual (offered from 1994 to 1995 in North America for MY 1995, and from 1993 to 1996 in Europe) or a 5-speed automatic. A total of 26,485 units were produced[18], with only 3,203 units equipped with a manual transmission.[citation needed] Initially, the V8 models were differentiated from other models by the wider grills. In 1994 the wide grills became available on other models as well.

North American model range[edit]

The E34 range was launched in October 1988 in North America with the 525i and 535i 6-cylinder models for the 1989 MY.[19] Over the course of the E34 generation, the 525i Touring, 530i, 530i Touring, 540i and M5 models were sold in North America. Each model was released earlier in Europe than in North America.[citation needed]

M5 version[edit]

M5 Touring

Introduced in September 1988[20] and produced until August 1995, the E34 M5 was produced in both sedan and Touring body styles, a first for the badge.

The E34 M5 is powered by the S38 straight-six engine, originally with a displacement of 3.6 L (220 cu in) and an output of 232 kW (311 hp; 315 PS), later upgraded to a 3.8 L (232 cu in) engine producing 250 kW (340 PS; 335 hp). This 3.8 litre version of the M5 was first seen by the public at the 1991 Frankfurt Motor Show, where the E34 M5 Touring also saw its debut.[20]

In its last year of production BMW used the Getrag 420G 6-speed manual gearbox, which was also used in the 8 Series and the 540i, as well as the subsequent E39 5 series.

Special models[edit]

518g[edit]

A model which could run on natural gas (as well as petrol) and was only sold in Germany. The 518g was based on the 518i wagon and the only transmission available was a 5-speed manual.[21] When running on natural gas, the engine produced 73 kW (98 hp),[22] compared with 84 kW (113 hp) when running on petrol. It was only produced in 1995 and just 298 units were built.[18]

518iev prototype[edit]

After unveiling the BMW E1 and E2 Electric Vehicles (EVs) in 1992, BMW began a project to show it was possible to make full-sized electric car, something few others would countenance due to the weight of the battery technology at the time. To make it possible despite the lead-based batteries, the 518iev,[23] had a modified 4 cylinder drive-line fitted with CVT, battery packs and ground-breaking rotating-field AC electric drive. This configuration was the predecessor of present-day EV Hybrids. BMW built at least one fully functional e34 prototype; however, very little was recorded about it that exists online. Extensive testing of this (and many others) in the late nineties was carried out with partners such as Deutsche Post, however the company did not utilise improvements in battery technology in the years following to advance electric technology in production until BMW announced ActiveE prototypes in 2010 (preceding the BMW i3 and i8) and 'Efficient Dynamics' models.

540i M-sport / M540i / 540i LE[edit]

540i with "throwing star" wheels

Because the M5 was discontinued for non-European markets in 1993, the 540i M-Sport model was built in 1995 for the North American market.[24] On top of the regular 540i features, additional features included sports suspension equipped with EDC, bolstered sport seats, servotronic steering, and M5 brakes.[25] 205 "M-Sport" models were built, 139 of them with the 6-speed manual transmission.[24]

The M540i model was sold in Canada. It includes the features of the North American 540i M-sport, plus upgraded brakes, 18-inch wheels M-parallel and various trim pieces.[26] Only 32 of these cars were built, all with a manual transmission.[24]

The 540i LE (ie. Limited Edition) sedan was sold in Australia[27] and the United Kingdom.[28] The 540i LE included the interior from the M5, "throwing star" M-System II wheels, EDC suspension with self leveling rear, Servotronic power steering, and front air dam. 70 of these 540i LE sedans were produced, all with a manual transmission, each individually numbered and identified by an engraved metal plaque stuck onto the centre console beneath the handbrake lever.[24]
