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.<ref>Template:Cite news</ref><ref>Template:Cite news</ref>

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").<ref name=":1" />

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.<ref>Template:Cite web</ref>

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

To reduce weight, the doors and bonnet are made of aluminium,<ref>Template:Cite web</ref> and the boot and front wings are made of carbon-reinforced plastic. The kerb weight is Template:Convert.Template:Citation needed
