A four-door sports car has been added to the new BMW 8 Series range. Joining the BMW 8 Series Coupe and BMW 8 Series Convertible as the third model in the 8 Series range, the Gran Coupe has a character all of its own, combining performance and design shaped by dynamism and elegance with significantly increased spaciousness for passengers in the rear seats. It's a stunning looking car and I think it may very well be the best looking BMW made in at least a decade.
The four-door model has a 3,023-millimetre wheelbase – an increase of 201 millimetres over the BMW 8 Series Coupe – and measures 5,082 millimetres in length (+ 231 mm), 1,932 millimetres in width (+ 30 mm) and 1,407 millimetres in height (+ 61 mm). The Gran Coupe’s front section is identical to the 8 Series Coupe’s design up to the point where the A-pillars start. The wide, low-slung front end exudes sporting intent and a confident presence. Adaptive LED headlights are fitted as standard. The optional BMW Laserlight with Selective Beam produces a high-beam range of around 600 metres.
As well as its distinctive proportions, the design of the new BMW 8 Series Gran Coupe’s flanks and rear end also clearly distinguishes it from its 8 Series stablemates. Because the windscreen frame is more upright, the roofline is also higher, meaning additional headroom in both the front and rear. The roofline merges into the tail in a graceful sweep, via a fin-shaped transition in the vicinity of the C-pillars that emphasises the elongated silhouette. The rear window, meanwhile, also follows a slightly steeper line in order to produce a larger boot aperture. An additional character line accentuates the elegance of the body and powerfully flared surfaces integrate pronounced shoulders into the overall effect. The side window graphic reaches its conclusion at the rear in another hallmark BMW design cue. On the new BMW 8 Series Gran Coupe, the counter-swing at the trailing edge of the side window graphic – the Hofmeister kink – is very upright in form, further emphasising the solidity of this area of the body. The powerfully flared wheel arches and wide track also play a defining role in the form of the rear end. Horizontal lines and sculptural surface contours give the tail a broad but also light appearance. The slim all-LED rear light clusters extend deep into the flanks. And twin exhaust tailpipes with a trapezoidal contour are positioned either side of the rear apron’s lower section.
The distinctive style of the new BMW 8 Series Gran Coupe is also expressed in the design of its interior. The extra length of the wheelbase and generously sized door apertures give passengers in the rear unprecedented legroom for a BMW coupe – and they are able to get in and out more easily than ever as well. Those in the rear seats also benefit from substantially greater shoulder room and headroom than in the two-door version of the new BMW 8 Series, making the second-row seats even more comfortable to travel in. The optional panoramic glass roof helps to give the interior of the new BMW 8 Series Gran Coupe an exceptionally light-filled feel. It is particularly generous in width and its glass surface area measures around 1.5 square metres. The result is an unbroken glass surface extending from the windscreen to the rear window. The front section of the roof and the interior blinds open and close at the touch of a button or with the radio remote control, delivering a controlled supply of fresh air. The rear blind can also be opened and closed from the rear compartment. A four-zone automatic climate control system and electric sun blinds for the rear side windows and rear window are both available exclusively for the four-door variant in the new BMW 8 Series line-up.
The aerodynamic properties of the new BMW 8 Series Gran Coupe have been honed by features including an almost completely sealed underbody, active air flap control, Air Curtains and the super-slender exterior mirror bases. An intelligent material mix, meanwhile, has helped to reconcile exacting demands on body rigidity with the goal of minimising weight. As well as the doors and the outer skin of the roof, the bonnet, front shear panel, engine subframe, front bulkhead and rear bumper support are all 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 distribute it to optimum effect. As a result, the four-door version’s weight penalty over the BMW 8 Series Coupe has been limited to around 70 kilograms. Fitting the optional carbon-fibre roof lowers the car’s centre of gravity even further and there is also the option of an M Carbon exterior package comprising air intake bars, exterior mirror caps and a rear diffuser insert all made from CFRP.
In the engine department, the same three choices from the Coupe will be available. The BMW M850i xDrive Gran Coupe has an output of 530 hp and peak torque of 750 Nm (553 lb-ft). The new V8 engine in the BMW M850i xDrive Gran Coupe accelerates from 0 to 100 km/h (62 mph) in 3.9 seconds. The BMW 840i Gran Coupe and BMW 840i xDrive Gran Coupe models come with a 3-liter straight six engine with 340 hp and torque peaking at 500 Nm (369 lb-ft). The new BMW 840i Gran Coupe powers from rest to 100 km/h (62 mph) in 5.2 seconds, the new BMW 840i xDrive Gran Coupe in 4.9 seconds. The unprecedented presence of a diesel engine in this segment makes it possible to combine sporting qualities with outstanding long-distance capability. The 3.0-litre straight-six diesel unit gracing the new BMW 840d xDrive Gran Coupe comes with all the right tools for the job. Maximum output of 320 hp and peak torque of 680 Nm (501 lb-ft) create an engine equally as adept when cruising effortlessly at low revs and putting in a powerful burst of speed. The BMW 840d xDrive Gran Coupe races from 0 to 100 km/h (62 mph) in 5.1 seconds.
