Chronology
Predecessor BMW 5 Series (E34)
Successor BMW 5 Series (E60)

The BMW E39 is the fourth generation of BMW 5 Series, which was sold from 1995 to 2004. It was launched in the sedan body style, with the wagon/estate body style (marketed as "Touring") introduced in 1996. The E39 was replaced by the E60 in 2003, however E39 Touring models remained in production until 2004.[2]

The E39 was the first 5 Series to use aluminium components in the front suspension. The proportion of chassis components using aluminium significantly increased for the E39,[3] in order to reduce weight. It was also the first 5 Series where a four-cylinder diesel engine was available.

V8 models use recirculating ball steering (as per previous 5 Series generations), however rack and pinion steering was used for the first time, in the four-cylinder and six-cylinder models. Unlike its E34 predecessor and E60 successor, the E39 was not available with all-wheel drive.

The M5 sedan was introduced in 1998, powered by the 4.9-litre S62 V8 engine.

Development and launch[edit]

Development for the E34's successor began in early 1989,[citation needed] (internally known as "Entwicklung 39") and ended in 1995. The final design by Joji Nagashima was selected in June 1992[4][5] and later frozen for production under new design chief Chris Bangle. With design selection in 1992, the series development phase began and took 39 months till start of production. The domestic German design patent was filed on 20 April 1994, utilizing an E39 prototype.[6]

In May 1995 BMW published the first official photos of the E39.[7] The E39 premiered in September 1995 at the Frankfurt Motor Show (IIA).[8] In December 1995 sales began on the European mainland.[9]

The first pilot production models were built in February 1995, with full-scale production starting later in the year. Most cars were built at the Dingolfing factory.[10]

Body[edit]

530d Touring (post-facelift)

Compared with its E34 predecessor, the E39 wheelbase grew by 68 mm (2.7 in) and overall length by 55 mm (2.2 in). Torsional rigidity was increased over the E34 by 40 percent, which reduces body flex and allows the suspension to operate more accurately, also improving ride quality.[11] Due to a stiffer body shell, the weight of the chassis increased by 10 kg (22 lb),[12] which is offset by the reduced weight of some aluminium suspension components.

Structural dynamics was also an objective of the body design, so the body's frequencies for torsional twisting and bending are in separate ranges and above natural frequency. These frequencies are out of the range of engine and driveline vibrations, to avoid vibrations being amplified.[11]

The aerodynamic design of the E39 resulted in a drag coefficient of 0.28.[4]

The E39 draws heavily from the E38 7 Series in body construction and electronic technology.

Steering[edit]

Unusually, two different steering systems were used for the E39, depending on the engine. Models with four-cylinder and six-cylinder models use rack and pinion steering,[13] the first time this system has been used in a 5 Series. This system steers from the front of the axle.[11] Models with V8 engines use recirculating ball steering, as per the previous generations of 5 Series.[11]

Suspension[edit]

The front suspension consists of MacPherson struts,[14][15] with six-cylinder cars using an aluminium front subframe. Aluminium is used for the steering knuckles, outer strut tube and the spring pads, resulting in a weight saving of 21 kg (46 lb).[11] V8 models also use aluminium in the steering box and several suspension links,[11] to compensate for the heavier steel subframe.

The rear suspension consists of a four link design (called "Z-link"), which is similar to the system used by the E38 7 Series. Chapman struts are used and the design minimises unintentional toe angle changes, which increases the stability of the handling.[11]

Drivetrain[edit]

ZF 5HP-30 automatic transmission

Manual transmissions[edit]

  • 5-speed ZF S5-39DZ[16] (525d,530d)
  • 5-speed S5D 250G (523i,528i from 1996, 520i, 525i)
  • 5-speed S5D 260Z (525td)
  • 5 speed S5D 320Z (523i up to 1996, 530i, 535i)
  • 6-speed Getrag 420G[16] (540i, M5)

Automatic transmissions[edit]

Note that the 523i, 525i, 528i and 530i had several overlapping automatic transmission options for some years.

Equipment[edit]

A "latent heat accumulator" was available as an option up until September 1999.[19][20] The accumulator stores engine heat by converting a salt from a solid to a liquid form (Phase transition).[21][22] The insulated tank can store heat for several days. The next time the vehicle is started, this heat is automatically used to reduce exhaust emissions (by heating the engine up to operating temperature quicker), for cabin heating and window defrosting.[23]

Separate to the latent heat accumulator is the Residual Heat function (activated by a button labelled "REST"), which allows the demister and cabin heater to use the heat of an engine that has recently been turned off (using an electric pump to push hot coolant through the heater core).

Standard equipment on the launch models included dual front and side airbags, pretentioners and load limiters for the front seatbelts,[24] anti-lock brakes, traction control, power steering, and air conditioning.[25][26] Satellite navigation was also available, initially using maps on CD, then moving to DVD maps in 2002.

Engines[edit]

At launch, the petrol engines consisted of the M52 straight-six and M62 V8,[27] which were both new engines at the time. In 1998, the "technical update" (TU) versions of these engines were introduced, which introduced double VANOS to increase torque at low rpm.[28] At the 2000 facelift (LCI), the M52 straight-six engine was replaced by its successor the M54, however the M62TU remained in use for the V8 models.[29]

The initial diesel models used the M51 straight-six turbo-diesel engine. In 1998, its successor the M57 was introduced, however the M51 also remained in production for two more years. In 1999, the M47 four-cylinder turbo-diesel was introduced in the 520d model, which is the only E39 model to use a four-cylinder engine.[30]

M5 version[edit]

M5 (post-facelift)

The M5 version of the E39 was Introduced in 1998 at the Geneva Motor Show and was produced from 1998 to 2003. It was powered by the S62 V8 engine. All E39 M5 cars were sold in the sedan body style with a 6-speed manual transmission.

Alpina B10 and D10[edit]

Alpina B10 V8

The petrol engined Alpina B10 3.2, 3.3, V8 and V8S models were built as sedans and wagons based on the E39 from January 1997 to May 2004.[35]

In February 2000, Alpina introduced the Alpina D10 Biturbo, the first six-cylinder diesel model produced by Alpina, The engine, a 3.0 liter twin turbocharged unit with 180 kW (245 HP) and 500 Nm of torque, was based on the engine of the BMW 530d.[35]

Protection line[edit]

The 540i Protection light-armored vehicle was launched in Europe on September 1997 and in North America from January 1998, The base price in 1998 was US$88,000.[36] These models included aramid fiber armor, bullet-resistant glass that is coated with polycarbonate to reduce spall. The 540i Protection is rated to withstand the impact of handgun fire up to and including .44 Magnum,[37] the glass is also protected from attack with blunt objects such as baseball bats and bricks.[38] The additional security measures brought an additional weight of 130 kg compared to the normal 540i sedan.[39] on request, an intercom system was available and from January 1998 a run-flat tire was available.[37]

North American model range[edit]

From 1997–1998, the E39 model range in North America consisted of the 528i and 540i, In 1999 the M5 was introduced. In 2001, the 528i was discontinued and replaced by the 525i and 530i.

In 2001, the American market 540i's power output was increased to 216 kW (290 hp),[40] unlike other markets where the 540i's power remained at 210 kW (282 hp).[41]

Model year changes[edit]

Most changes occur in September each year, when the changes for the following model year go into production, as is typical BMW practice. Therefore, the changes for 1996 represent the 1997 model year, for example.
