Following the launch of the new BMW 8 Series Coupé and new BMW 8 Series Convertible, the new BMW 8 Series Gran Coupé is now poised to make its debut.
With its four-door body design, the BMW 8 Series Gran Coupé combines everyday practicality and supreme handling with the latest innovations in control/operation, driver assistance and connectivity.
The new BMW 8 Series Gran Coupé is the only model in its segment derived directly from a two-door sports car. It is a consequence of development alongside the new BMW 8 Series Coupé and M8 GTE racing car, which competes in the FIA World Endurance Championship (WEC) and the IMSA WeatherTech SportsCar Championship (IWSC) in North America. The world premiere of the BMW 8 Series Gran Coupé will be a highlight of the inaugural BMW Group #NEXTGen event in Munich on 25 June and the UK launch of the new car will commence in September 2019.
The design of the new BMW 8 Series Gran Coupé’s flanks and rear end distinguishes it from its 8 Series stablemates. The four-door model has a 3,023-millimetre wheelbase – an increase of 201mm over the BMW 8 Series Coupé – and measures 5,082mm in length (+231mm), 1,932mm in width (+30mm) and 1,407mm in height (+61mm). The front track width of 1,627mm is the same as the two-door car’s, while the rear track of 1,671mm is 28mm wider, making it the widest of any current BMW model.
The Gran Coupé’s front section is identical to the 8 Series Coupé’s design up to the start of the A-pillars. Because the windscreen frame is slightly more upright, the roofline rises to a greater height by the time it reaches the front seats, meaning additional front and rear headroom. The rear window follows a slightly steeper line in order to produce a larger boot aperture and the surface contouring around the C-pillars has been facilitated by a rear window that forms a fixed part of the body structure and a conventional boot lid. These two design features also have a positive impact on the body’s torsional rigidity and acoustic comfort in the car’s interior.
The slim twin headlights are positioned slightly higher and define the brand’s signature look with LED units generating both the daytime driving lights and low/high-beam headlights from the two pairs of light tubes. Adaptive LED headlights featuring variable light distribution and cornering lights come as standard. There is also the option of BMW Laserlight with variable road illumination and Selective Beam, which produces a high-beam range of around 600 metres.
The side view is composed of just a few character lines that trace the flow of air exiting the Air Breathers. The side window graphic reaches its conclusion at the rear in another hallmark BMW design cue – the Hofmeister kink.
At the rear, twin exhaust tailpipes with a trapezoidal contour are positioned either side of the rear apron’s lower section. The tailpipes are integrated into the diffuser element on the BMW M850i xDrive Gran Coupé and on models specified with the M Sport package.
The optional panoramic glass roof is specific to the new BMW 8 Series Gran Coupé. The continuous glass surface extends from the windscreen back to the rear window and results in a total glass surface area of around 1.5sq m. The front section of the roof has an electric mechanism that allows it to be opened and closed at the touch of a button or with the radio remote control, while the rear blind can be opened and closed from the rear compartment.
The new BMW 8 Series Gran Coupé features an almost completely sealed underbody, active air flap control with adjustable kidney grille slats, air curtains in the front apron and super-slender exterior mirror bases. An additional front spoiler lip on the BMW M850i xDrive Gran Coupé minimises front-axle lift at high speeds.
An aluminium monocoque construction is used for its doors and the outer skin of the roof, while elements such as the bonnet, front shear panel, engine subframe, front bulkhead and rear bumper support are also made from aluminium.
The plastic boot lid, the magnesium cockpit support and the use of carbon fibre-reinforced plastic in the centre tunnel help to both reduce weight and optimise distribution. As a result, the four-door is only 70kg heavier than the Coupé.
Fitting the optional carbon-fibre roof lowers the car’s centre of gravity even further and there is also the option of a Carbon package comprising air intake bars, exterior mirror caps and a rear diffuser insert all made from CFRP.
Updates to engine technology have improved power delivery and thrust to go with the acoustic charge from the standard flap-controlled M Sport exhaust system. The new V8 delivers peak torque of 750Nm with a maximum power output of 530hp.
