BMW 6 Series (E63)

The second generation of the BMW 6 Series consists of the BMW E63 (coupe version) and BMW E64 (convertible version) grand tourers. The E63/E64 generation was produced by BMW from 2003 to 2010 and is often collectively referred to as the E63.

The E63 uses a shortened version of the E60 5 Series chassis and subsequently shares many features. The car initially drew criticism, due to its controversial styling and complicated iDrive system.

The M6 model was introduced in 2005 in coupé and convertible body styles. It is powered by the S85 V10 engine shared with the E60 M5, and most M6s were produced with a 7-speed automated manual transmission ("SMG III").

In March 2011, the BMW 6 Series (F06/F12/F13) began production as the successor to the E63.

Development and launch
The exterior was designed by Adrian van Hooydonk, based on the 1999 BMW Z9 concept car designed by the then BMW Design Chief Chris Bangle.

The controversial rear styling, first seen on the E65 7 Series, was nicknamed "Bangle Butt" by critics. BMW described the styling philosophy as "flame surfacing", where concave and convex shapes meet to create sharp edges.

To reduce weight, the doors and bonnet are made of aluminium, and the boot and front wings are made of carbon-reinforced plastic. The kerb weight is 1490 - 1930 kg.

Coupé (E63)
Coupé models were unveiled at the 2003 Frankfurt Auto Show, and introduced on the market in middle of the 2003 model year.

Convertible (E64)
Convertible models were unveiled at the 2004 Detroit Auto Show, and released in mid 2004.

Convertible models featured a non-conventional convertible top design with side fins and an integrated wind deflector that can be raised or lowered at any time.

Engines
Top speed for all models is electronically limited to 250 km/h.

Drivetrain
The available transmissions are:
 * 6-speed ZF S6-37 manual (630Ci / 630i)

M6 model


The M6 version was initially introduced as a coupé at the 2005 Geneva International Motor Show, and later in convertible form at the British International Motor Show in 2006.

The M6 is powered by the 5.0-litre naturally aspirated S85 V10 shared with the E60 M5, generating 373 kW at 7,750 rpm and 520 Nm at 6,100 rpm. The majority of the cars were produced with a 7-speed automated manual transmission ("SMG III"), however a 6-speed manual transmission was also available in the United States.

The M6 coupé has a carbon fibre roof in order to reduce weight and for a lower centre of gravity. Additional features included: sports seats, larger front and rear brakes, an M-performance instrument cluster, a carbon-fibre roof (coupé only), and an optional M head-up Display. The car also has quad exhaust-pipes and larger, more aerodynamic air intakes.

A total of 9,087 coupés and 5,065 convertibles were built; amounting to 14,152 cars.

Safety
Models feature BMW's Advanced Safety System, enabling the car to decide the most effective deployment of the airbags in a crash. Safety equipment includes active anti-roll bars, dynamic stability control, front knee airbags (in accordance with US regulation), BMW roadside assistance, and an SOS emergency system. Convertible models also feature an automatic rollover protection system, where roll-bars behind the rear seats are automatically deployed in a rollover. From 2008, active head restraints became a standard feature on all seat options, reducing the risk of neck injuries in a rear-end collision.

Production volumes
The E63/E64 was produced at the Dingolfing BMW plant.
