F93 BMW M8 Gran Coupé: four-door coupé with 625 hp

With BMW having long telegraphed its intention to introduce a Gran Coupé version of its M8 with a concept car last year, it was bound to happen sooner or later. Welcome, then, to the F93 BMW M8 Gran Coupé, which gets all the goodies of its Coupé and Convertible siblings in a svelte four-door coupé body style.

This, of course, means the inclusion of the S63 4.4 litre twin-turbocharged V8, which has already seen service in the F90 M5 and the new X5 and X6 M. Fitted with the latest Valvetronic variable valve lift technology, 350 bar high-precision direct fuel injectors and turbos mounted within the V of the engine, it produces a beefy 600 hp at 6,000 rpm and 750 Nm of torque between 1,800 and 5,600 rpm.

All this is sent to an M xDrive all-wheel drive system via an eight-speed M Steptronic automatic transmission with Drivelogic settings. With all that power, the Gran Coupé will sprint from zero to 100 km/h in just 3.3 seconds (exactly the same as the two-door, even though it carries an extra 95 kg), and while the top speed is limited to the usual 250 km/h, specifying the M Driver’s Package brings that figure up to 305 km/h.

Think that’s fast? Think again – just like the standard M8, the Gran Coupé is also available in Competition form, which raises the power figure to 625 hp and extends peak torque output to 5,800 rpm. It also gets stiffer engine mounts that ensure quicker throttle response and a more instantaneous turn-in, along with a switchable M Sport exhaust system that is optional on the “regular” model. This all slashes a tenth off the zero-to-100 km/h time, to a blistering 3.2 seconds.

Torque distribution between the front and rear wheels varies depending on the conditions and chosen setting. While the system has a standard rear bias, putting the car in 4WD Sport mode sends even more torque to the rear axle; as the name suggests, the hardcore 2WD mode – only available with the stability control off – gives you full rear-wheel drive for some sideways hooning. An Active M Differential continues to be fitted at the rear.

It may be billed as a high-performance sports car, but the addition of an extra 200 mm to the wheelbase is said to have given the Gran Coupé version a more comfortable demeanour. All the chassis and control systems have been recalibrated to deliver a better ride without sacrificing the car’s dynamic capabilities.

As with the Coupé, the sharpened chassis features adaptive dampers and bespoke kinematic and elastokinematic properties to provide precise wheel location and directional stability. The double wishbone front suspension employs special swivel bearings, torque arms and control arms, along with elastomer bearings to channel the forces acting on the suspension across the subframe and body structure.

Meanwhile, the five-link rear axle gets M-specific forged links to improve agility, plus stiffer anti-roll bars for more precise suspension and damping responses. Torsional rigidity has also been increased through the use of a tower-to-bulkhead strut and a stiffer shear panel with integrated side sill connection at the front, as well as a steel cross-brace and an aluminium transverse strut at the rear. The Competition model benefits from increased front camber and the use of ball joints on the rear toe links, further improving cornering dynamics.

Also fitted is a brake-by-wire system with a compact module that integrates the brake activation, boosting and control functions, along with a vacuum-free brake booster. The system is lighter than a regular hydraulic braking setup and provides instant brake pressure, faster and more precise stability control interventions and optimum pedal feel – even through slippery conditions, hard cornering or high braking temperatures.

The system also gives drivers the choice of Comfort and Sport settings that alter the ferocity of brake pressure delivery, selectable through the new Setup button which also controls the engine, gearbox, suspension, variable ratio steering and all-wheel drive settings. Another new button, M Mode, alters the driver assistance systems and the information presented on the car’s screens to suit the driver’s mood.

In the default Road setting, all systems and displays function as normal, but pressing the button once puts the car into Sport mode. Here, the head-up display and instrument display show only relevant vehicular information, and the driver can also turn off all driver assists bar autonomous emergency braking and the Evasion Assistant. The Competition models gain a Track mode that turns all assists, the centre screen and the audio system off, enabling the driver to focus on balls-to-the-wall driving.

Visualising the extra performance is the exterior design that has been finessed for a more muscular appearance, going well with the Gran Coupé’s stretched silhouette. At the front, you get massive triple air intakes and a jutting front splitter, while the rear features a large diffuser with the trademark quad exhausts. The front fenders have also been pumped up to fit the wider track and feature large Air Breather vents.

Also fitted are a subtle rear spoiler, M-specific twin-spar door mirrors and a double-bubble carbon fibre roof. Large 20-inch alloy wheels come as standard and hide M compound brakes measuring 395 mm at the front, or 400 mm with the optional M carbon ceramic brakes. The Competition model add gloss black exterior highlights and complex forged alloys, and an M Carbon exterior package is also available.

Inside, you’ll find the usual sports seats with perforated three-dimensional quilting, larger side bolsters, integrated headrests and an illuminated M8 badge, along with a unique steering wheel with red M1 and M2 buttons for calling up your favourite vehicle settings. There’s also a red starter button and a new electronic gearlever, embossed and featuring M colour stitching and a cut-out with “waterfall” lighting.

The M8 comes as standard with full Merino leather upholstery, but Competition models also get the option of leather and Alcantara trim in a contrasting two-tone colour scheme. The latter also gets Alcantara on the centre console, lower dashboard and the Coupé’s BMW Individual headlining.

Exclusively for the M8 Gran Coupé, BMW is introducing a First Edition model that captures the extroverted aesthetic of the aforementioned concept. Limited to just 400 units, it is painted in a striking BMW Individual Aurora Diamond Green metallic and gets Gold Bronze accents on the badges, window trim, fender vents, door sill plates and light alloy wheels. The interior is also upholstered in Taruma Brown Merino leather.
