The fifth generation of the BMW 5 Series executive cars consists of the BMW E60 (sedan version) and BMW E61 (wagon version, marketed as 'Touring'). The E60/E61 generation was produced by BMW from 2003 to 2010 and is often collectively referred to as the E60. The E60 generation introduced various new electronic features, including the iDrive infotainment system, head-up display, active cruise control, active steering, adaptive headlights, night vision, lane departure warning and voice control. The E60 was the first 5 Series to be available with a turbocharged petrol engine, a 6-speed automatic transmission and regenerative braking. The M5 model was introduced in 2005 and is powered by the BMW S85 V10 engine. It was sold in the sedan and wagon body styles, with most cars using the 7-speed SMG III transmission. It was the first and only M5 model to be sold with a V10 engine. In January 2010, the BMW 5 Series (F10) began production as the successor to the E60. Development and launch The development programme for the E60 began in 1997, concluding in 2002. The lead designer was Boyke Boyer. The final design, developed by Davide Arcangeli under BMW Design Director Chris Bangle, was approved in 2000 and German design patents filed on 16 April 2002. The sedan was launched on 5 July 2003 in Europe and in October 2003 in North America. In late 2004, the Touring models were introduced. Body styles The body of the E60 was made using aluminium for the front of the car, and steel for the passenger cabin and rear. Kerb weights are for the sedan and for the wagon. The weight distribution of the sedan models was 50:50. Interior / Equipment The iDrive infotainment system— first introduced in the E65 7 Series— was fitted to all E60 models. The standard iDrive system included a 6.5-inch LCD screen, a single-disc CD/MP3 player, Bluetooth for phone calls (available only on later-build 2004 models, and standard on all 2005 and newer models), basic voice control, and vehicle settings. Optional features included an 8-inch LCD screen, GPS navigation, Sirius Satellite Radio (on North American-spec models), and DVD video playback. iPod and USB integration, HD Radio (on North American-spec models), an auxiliary audio input jack (standard on 2008 and newer models), full voice control, and a multi-disc CD/MP3/DVD changer (mounted in the glove compartment).
