Chronology
Predecessor BMW 3 Series (E36)
Successor BMW 3 Series (E90)

The BMW E46 is the fourth generation of the 3 Series compact executive cars, produced by BMW. It was produced from 1998 when it succeeded the BMW E36.

The E46 was released in May 1998 to worldwide markets in the sedan body style. In 1999, a coupé and touring body style became available to all markets, and the sedan was released in the United States. A convertible and hatchback body style was released in 2000, the latter only for Europe, South Africa, Australia and New Zealand. The E46 experienced enormous success in all markets and was widely considered the performance benchmark of its class.[5] The record selling year for the E46 chassis was 2002, when 561,249 vehicles were sold worldwide.[6] The main competitors during the E46's production run were the Alfa Romeo 156, Audi A4, Lexus IS/Toyota Altezza, Mercedes-Benz C-Class, Saab 9-3 and the Volvo S60.

BMW M GmbH produced a high-performance variant of the E46 chassis, designated the M3. This version had a larger, more powerful engine, sportier suspension, a limited slip differential, and various aesthetic modifications. The M3 was released in 2001 and was available in coupé and convertible body styles. It was offered with two transmissions: a standard 6-speed manual or an optional sequential manual gearbox.

Design

Exterior design

The E46 was developed as an evolutionary replacement for the BMW E36 chassis. In 1995, the general exterior design of the E46 by Erik Goplen was approved and as a result DesignworksUSA was contracted by BMW to work alongside BMW Group's in-house design team to create the exterior body work for the 3-Series range in February 1996.[7][8] Based on the E36 body shell, the design team put an emphasis on improving aerodynamics and increasing the car's aggressive stance.[7] Design patents were filed in Germany on July 16, 1997 and in the US on January 16, 1998.[9] While the styling of the E46 was seen as an evolution of the extremely successful previous generation 3-series, it was not immediately embraced by either the buying public, or the automotive press. Word leaked out in the press that the BMW stylists were unhappy in raising the roof-line, and the general "rounding" of the body panels in comparison to the more squarish E36 series. Chris Bangle was responsible through January 1996 for the production saloon exterior, as evident in the 1997 design patent. Production development of the saloon took 24 months from January 1996 to January 1998. Goplen designed the production coupé and estate during 1996–1997.[10]

Interior design

Since the start of production, the entire in-car entertainment system (Radio Function, Navigation System, Television and Telecommunications systems) is based on a very flexible automotive computer system.[11] As a result the E46 models can all be easily upgraded with the newest BMW technologies including BMW's Bluetooth System, the DVD based Navigation system, as well as BMW's CD changers that play MP3s[12]

Weight and rigidity goals

An emphasis was put on reducing unsprung weight and increasing structural rigidity rather than increasing power output: the highest displacement model at release, the E46 328, had only 3 horsepower more than the E36 328.[13] To counter this small power increase, the body shell of the E46 was claimed by BMW to be 70% more rigid than the E36's,[13] and aluminum suspension components were used increasingly in order to decrease unsprung weight.[13] However, with a curb weight of 1450 kg,[14][15] the E46 328ci is 55 kilograms (121 lb) heavier than the E36 equivalent.[16][17]

In tune with BMW's core values,[18] the E46 was released with a front engined rear-wheel drive layout with 50/50 weight distribution.[13][19] This balance allows for optimal handling in regard to the drive train layout.

SULEV

BMW introduced a super ultra low emission vehicle (SULEV) into the select regions of the United States to meet stricter emission standards. California, New York, and Massachusetts received the SULEV E46's in 2003, and Vermont in 2004.[20] They received a variant of the M54 engine, the BMW M56.[20] The M56 meets SULEV standards, as well as partial zero emission vehicle (PZEV) and zero evaporative emissions requirements.[20] The M56 is claimed to have identical power as its M54 counterpart.[20]

Specifications

Performance package (ZHP)

2005 BMW 330Ci ZHP in Titanium Silver

The performance package was an inclusive option (sold in North America) given to E46 sedans from 2003 to 2005, coupes and convertibles from 2004 to 2006.[56] It included various aesthetic changes over the regular 3 series, as well as functional and mechanical enhancements. The ZHP was equipped with sportier cam shafts and a more aggressive DME tune to increase power from 225 hp (168 kW) to 235 hp (175 kW).[56] Suspension was modified over the standard suspension with firmer springs and dampers, larger anti-roll bars, stronger front control arm ball joints, a lower ride height, and slightly more negative camber.[57] Car and Driver magazine track-tested the car, which returned a 0–60 mph time of 5.6 seconds and passed through the 1/4 mile in 14.3 seconds.[57]

Motorsport

Andy Priaulx was the champion of the 2004 European Touring Car Championship season and 2005 World Touring Car Championship season driving a 320i.[58] Franz Engstler won the 2006 Asian Touring Car Championship season in a 320i.[59]

The car has further competed in the British Touring Car Championship, the European Touring Car Cup and the Russian Touring Car Championship.
