Chronology
Predecessor BMW 7 Series (F01)

The BMW 7 Series (G11) is a full-size luxury car manufactured by German automotive manufacturer BMW. Succeeding the BMW F01, it is the sixth generation of the BMW 7 Series. The G11 was unveiled on June 10, 2015 at BMW's headquarters in Munich.[5] An official public reveal took place at the 2015 International Motor Show Germany.

G11 is the codename for the short-wheelbase model, the extended wheelbase model is codenamed G12 and designated with an additional L letter. This generation of the 7 Series is the first car lineup of BMW to be based on the CLAR platform.[6] The CLAR platform adopts technology first introduced in BMW i models, namely the introduction of carbon-fibre-reinforced polymer as structural chassis components.

As part of BMW's strategy of introducing plug-in hybrid variants for all future car models,[7] both, the short and long-wheelbase models were available available with hybrid powertrains under the designations 740e and 740Le in 2016.[8]

Launch

The international launch of the new BMW 7 Series was at the 2015 Internationale Automobil-Ausstellung in Frankfurt am Main, Germany. Held in September 2015.

Production commenced in July 2015 at the Dingolfing manufacturing plant in Germany,[9] with global vehicle sales starting in October 2015.[10][11][12]

Engineering

BMW 740d Short Wheelbase - SWB
BMW 750Li Long Wheelbase - LWB

The G11 and G12, which are the respective codenames for the short and extended wheelbase models, are the first passenger BMW vehicles to be based on the modular BMW CLAR (cluster architecture) platform.[13]

The passenger cell of the 7 Series is made of carbon-fibre-reinforced polymer (CFRP), tensile steel and aluminium, resulting in a lower kerb weight, lower centre of gravity and maintaining a 50/50 axle load distribution. The usage of CFRP allows for weight reduction due to being lighter than steel and aluminium. CFRP also increases structural strength in areas exposed to high steering forces, as it is capable of diverting impact forces to prevent deformations of the material, resulting in higher torsional rigidity.[14] Aluminium has been applied to the doors, boot lid, brake system, wheel hubs and rear suspension arms, further reducing weight and unsprung masses. The G11's body weighs overall 40 kg less than that of its predecessor.[15]

The front features a large signature kidney grille incorporating grille shutters that will only open when an increase of air flow to the engine bay is required, decreasing aerodynamic drag in the process. Along with air openings behind the front wheel arches that reduce turbulence in the wheel housings, the drag coefficient has been reduced to 0.24.[16]

The standard self-levelling air suspension of the previous model has been reworked, featuring air springs at both axles with electronically-controlled shock absorbers that can automatically adjust damping according to the environment. The active anti-roll system is optionally available with an electro-hydraulic actuator that improves damper reaction times. For the first time, four-wheel steering, marketed as Integral Active Steering, has also become available for all-wheel drive models.[17]

Equipment

Interior

The iDrive operating system for secondary car controls now receives user input from a conventional control wheel, touchscreen, voice commands[18] and is capable of recognizing gestures through a 3D scanner. It is also possible to save a gesture movement with an individual function.

A number of advanced driver assistance systems for the BMW 7 Series have been reworked to work autonomously or partly so—the parking system utilises a number of radar sensors and a stereo camera at the rear, allowing it to execute parking maneuvres independently and can be operated with a digital key fob. The cruise control driver assist is able to recognize speed limits and will adjust the vehicle's speed accordingly. The lane driving assist warns the driver of possible side or rear collisions. In addition, it is able to detect lane markings and traffic, as well as alter the steering responsiveness to improve driving comfort.[19]

Engines

The powertrain line-up consists of a 4.4 litre V8 engine 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 including the hybrid model designated as 740e/740Le, or 730i/730Li for the petrol version. Initially, each model can be equipped with all-wheel drive and is mated to an 8-speed Steptronic ZF automatic transmission. The 750i/750Li, 740i/740Li and 740d/740Ld models are optionally available with the all-wheel drive option xDrive. The transmission can be optionally linked with the satellite navigation system that provides the transmission with geographical data to adjust shift timing in relation to current driving conditions.

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, which evolved from a 750i based mild hybrid to a 740i based full hybrid in 2014 post-LCI (Life Cycle Impulse) variant. The 740e is marketed as a BMW iPerformance car, not as a member of the BMW i sub-brand.[20][21][22]

740e/740Le iPerformance

In February 2016, BMW announced the introduction of the "iPerformance" model designation, which was to be given to all BMW plug-in hybrid vehicles from July 2016. The aim is to provide a visible indicator of the transfer of technology from BMW i to the BMW core brand. The new designation will be used first on the plug-in hybrid variants of the latest BMW 7 Series, the BMW 740e iPerformance being the first of such plug-in hybrids.[28]

2016 BMW 740e eDrive

The 740e iPerformance was unveiled at the 2016 Geneva International Motor Show, together with the new BMW M760Li xDrive and the BMW i8 Protonic Red Edition special-edition model.[28] Sales of the 740e iPerformance began in Germany in July 2016. Pricing starts at €91,900 (~US$101,000).[29]

The 740e iPerformance features the same drivetrain as the already launched BMW X5 xDrive40e plug-in hybrid, and has an all-electric range is 25 mi (40 km), dropping to 23 mi (37 km) in the xDrive version, both under the New European Driving Cycle (NEDC).[30] Under the EPA test cycle, the all-electric range was rated at 14 mi (23 km). According to EPA, the 740 burns some petrol during the first 14 miles, so the actual all-electric range varies between 0 to 14 miles.[31]

The 740e iPerformance mates a turbocharged 190 kW (258 PS; 255 hp) 2.0-litre, four-cylinder petrol engine with an electric motor, resulting in a combined power output of 240 kW (326 PS; 322 hp) and 400 N⋅m (295 lb⋅ft) of torque.[32] BMW’s Auto eDrive function allows drivers to choose how the 740e operates and features modes for pure electric driving and performance. Drivers can also select from the usual Eco Pro, Comfort and Sport modes too. The 740e can be charged in less than four hours from a domestic socket, or in under three hours from a wall charger.[30] All models get an eight-speed automatic transmission as standard. The 740e can sprint to 62 mph in 5.6sec - the long-wheelbase version is 0.1sec slower while the xDrive variant is 0.1sec faster.[30]

Official fuel economy figures under the NEDC test are 134.5 mpg‑imp (2.100 L/100 km; 112.0 mpg‑US), with CO2 emissions of 49g/km. The 740e will be available in both standard and long-wheelbase forms, and also as an all-wheel drive xDrive variant. In this form, the 740e returns 122.8 mpg‑imp (2.300 L/100 km; 102.3 mpg‑US) and emits 53g/km of CO2.[30] Under the EPA test cycle, the BMW 740e xDrive iPerformance has a combined city/highway fuel economy rating of 64 miles per gallon equivalent (MPG-e) (3.7 L/100 km), corresponding to an energy consumption of 52 kWh/100 mi. When running only on gasoline, the EPA-rated fuel economy is 27 mpg‑US (8.7 L/100 km; 32 mpg‑imp).[31]

Alpina B7

Alpina B7 Bi-Turbo

The Alpina B7 xDrive was announced by BMW North America on 8 February 2016 with sales starting in September 2016. With an electronically limited top speed of 310 km/h (193 mph) and a 0–100 km/h acceleration time of 3.7 seconds along with a sportier setup, it is the sportiest 7 Series but is sold by BMW only in the United States and Canada.[33] The B7 is sold in other countries by Alpina as the B7 Bi-Turbo, with a delimited top speed of 330 km/h (205 mph).

The Alpina B7 features a 447 kW (608 PS; 599 hp) 4.4 litre twin-turbocharged V8 engine delivering 800 N⋅m (590 lb⋅ft) of torque and a more luxurious interior. It was unveiled at the 2016 Geneva Motor Show.

M760Li xDrive

BMW M760Li

The M760Li is the flagship 7 Series model. It was unveiled in February 2016 and made its official public debut at the 2016 Geneva Motor Show. It is powered by BMW's N74B66 engine, a 6.6-litre twin-turbocharged V12 which generates a maximum power output of 449 kW (610 PS; 602 hp) and 800 N⋅m (590 lb⋅ft) of torque. If the optional M Driver’s Package is specified, the limited top speed is raised to 305 km/h (190 mph), versus 250 km/h (155 mph) as standard. As an M Performance model, the M760Li receives technical upgrades over the standard 7 Series, including M Performance-specific tuning of the transmission's shift programmes, 19-inch M Sport brakes, an M Sport exhaust system, performance tyres and standard fit Integral Active Steering. Initially, the M760Li was unveiled with a power output of 441 kW (600 PS; 591 hp),[34] this number being later increased to 449 kW (610 PS; 602 hp) for the Geneva motor show the following month.

The M760Li features several visual cues to differentiate it from base 7 Series models. These include a 20-inch alloy wheel design exclusive to the M760Li. Several pieces of exterior trim are finished in "Cerium Grey", most notably the mirror caps, side "Air Breathers" and the tailpipe embellishers. There are V12 badges on the C-pillars, and a unique tailpipe design at the rear.

The M760Li can also be specified as an "Excellence" model. This receives modifications to the exterior and interior which create a luxurious appearance, compared to the sporty aesthetics of the standard M760Li.[35]

Essentially, carbon fiber structural elements provide additional rigidity in key parts of the unibody structure, in some areas complementing aluminum and in others acting as standalone structural members. Suspension arms, steering knuckles and hubs were all redesigned to remove material without compromising strength, and additional aluminum helped reduce weight in areas like the doors, which are 10 percent lighter than those of the existing 7-series while still maintaining occupant protection characteristics. [...] Carbon fiber reinforced plastic is found in the B- and C-pillars, in the roof bows, along the center tunnel, on the package tray, in the sills, and [...] in a 9-foot arc that runs from the base of the A-pillar to the rear of the car along the roofline; [...].
