The 7 Series is BMW’s flagship car and is only available as a sedan or extended-length limousine. It traditionally introduces technologies and exterior design themes before they trickle down to smaller sedans in BMW’s lineup.
The first generation 7 Series was powered by straight-6 petrol engines, and following generations have been powered by straight-6, v8 and v12engines with both natural aspiration and turbocharging. Since 1995, diesel engines have been included in the 7 Series range.
The sixth generation of the 7 Series was revealed on June 10, 2015 at BMW’s headquarters in Munich. The G11 and G12, which is the codename for the extended wheelbase model, are the first passenger vehicles of BMW to be based on the modular BMW CLAR platform (cluster architecture). As development was heavily focused on reducing weight and increasing structural strength, the body construction uses a combination of carbon-fiber-reinforced polymer (CFRP), high-tensile steel and aluminium. The suspension received air springs at both axles that are adjustable with electronic shock absorbers.
The powertrain line-up consists of a 4.4 litre V8 and three engines from BMW’s modular B-series engine architecture – two 3.0 litre inline-six engines in petrol and diesel form, as well a 2.0 litre inline-four engine for the plug-in hybrid model known as 740e. Initially, each engine will be available with an 8-speed automatic transmission that can be linked with the satellite navigation system.
The G11 is the first 7 Series to feature a plug-in hybrid variant, called the 740e. This new model effectively replaces the rather undersold ActiveHybrid7, itself a mild hybrid. The 740e is marketed as a BMW, not as a member of the BMW i sub-brand.
Notable improvements to the infotainment and driver assistance systems include an automatic parking system that is controllable with a digital key fob and a more intuitive version of the iDrive vehicle operating system, featuring touchscreen input and gesture recognition controls.
