BMW M Family to expand with addition of BMW M6 Gran Coupé
In early summer 2013, the all-new BMW M6 Gran Coupé will join its famous BMW M5 Sedan and M6 Coupé siblings as what is perhaps the perfect combination of both. The BMW M6 Gran Coupé is an ultra-high performance, four-door Coupé design with stunning aesthetics, race-bred technology, and the signature driving character of BMW M GmbH.
The M6 Gran Coupé is made instantly unique among four-door vehicles by its bonded-in carbon fiber composite roof panel, similar to the one found on the M6 Coupé . Between the doors is a cabin of sensational Coupé -like design and first-class materials. The M6 Gran Coupé ’s control placement and – equally important – control feel are second to none. The four-plus-one seating arrangement allows the M6 Gran Coupé to carry four adults in luxury, and offers maximum seating capacity for five when needed.
Under the hood
The new M6 Gran Coupé features the most powerful engine ever fitted to an M production car, a 4.4-liter M TwinPower Turbo V-8 with 560 horsepower and an always-accessible 500 lb-ft of torque. With this endowment, the rear-wheel drive BMW M6 Gran Coupé practically rockets from 0 – 100 km/h in 4.1 seconds (preliminary) .
The new BMW M6 Gran Coupé focuses the gargantuan muscle of its engine on the road through one of the most advanced drivetrains BMW has ever developed. The high-torque 7-speed M-Double Clutch Transmission (M-DCT) borrowed from the M5 and M6 Coupé sends power uninterrupted to the innovative Active M Differential, which in turn perfectly balances power between the rear wheels. This advanced drivetrain, combined with truly radical chassis and suspension revisions to the BMW 6 Series Gran Coupé on which the car is based, ensure that the M6 Gran Coupé ’s substantial output is transferred to the ground predictably and repeatedly.
The High-Revving M V-8 TwinPower Turbo Engine.
The engine of the all-new M6 Gran Coupé has the highest output ever generated by a BMW M car, and provides a meaningful balance between ultra-high performance and fuel consumption. The engine’s operating behavior is characterized by traditional M traits like immediate throttle response and linear power delivery. Additionally, thanks to turbocharging, the engine features an unusually high and flat torque curve, sustaining peak torque from 1,500rpm – 5,750rpm. The engine produces about 10% more output than the M V10 engine which preceded it, and torque is up by over 30%.
To achieve the performance levels of the new M V-8, the engineers at BMW M GmbH started with the proven BMW M-developed 4.4-liter V-8 engine from the BMW X5 M and X6 M (internally known as the S63B44 engine) and further developed it for its duty in the latest M5 and M6 models. Internally designated S63B44Tü, this engine uses similar M Twin Power technology combined with the reverse-flow V-8 layout. The result is that the high-revving V-8 engine lends a fresh intensity to the powerful M car experience. The S63Tü develops a peak output of 560 hp at 5,750 – 7,000 rpm (versus 555 hp at 6,000 rpm for the S63), while its maximum torque of 500 lb-ft is on tap between 1,500 and 5,750 rpm (versus 500 lb-ft from 1,500 to 5650 rpm for the S63). The rev limiter intervenes at 7,200 rpm, up 200 rpm from the original S63 engine and now accessible in each gear until the top speed limiter intervenes. The rev band, which offers extreme acceleration between peak torque and the availability of maximum horsepower, is therefore almost three times as wide as that of the V10 engine from the previous generation of M engines.
The instant power delivery and sustained thrust of the M TwinPower Turbo V-8 results in acceleration from 0– 100 km/h in 4.1 seconds (preliminary) for the M6 Gran Coupé .
7-speed M Double Clutch Transmission with Drivelogic
The new V8 engine M TwinPower Turbo engine is mated to a newly developed 7-speed double-clutch transmission designed to handle the high torque and high revving nature of the engine. The M-DCT with Drivelogic, developed especially for the new M5 and M6, has been tuned to match the performance characteristics of the engine with the M6 Gran Coupé chassis. It delivers exceptionally fast and clean gear changes in both Automatic mode (D) and Manual mode (S). No clutch pedal is required for manual gearshifts and the driver can stay on the accelerator during gear changes (conditions permitting). The driver uses the model-specific M gear selector to choose between D and S modes and to engage Reverse. Comfort is further enhanced by the new Low Speed Assistance function, which smoothes power delivery in stop-and-go traffic with a light touch of the accelerator pedal.
Hallmark M design features are always influenced directly by technical considerations – such as cooling air requirements, chassis geometry, weight-and-balance, and aerodynamics. This form-follows-function philosophy opens a design window through which to see the performance capability of the BMW M6 Gran Coupé . The front of the car is dominated by its large air intakes, optional Adaptive LED Headlights and an M kidney grille designed especially for this model. From the side, the M four-door Coupé is clearly distinguishable from the BMW M6 Coupé thanks to its rear doors and 113-millimeter 4.45” longer wheelbase. The low roofline flowing smoothly into the rear, the shoulder line – which takes in the door openers – and side windows extending well into the C-pillars accentuate the dynamically stretched silhouette.
Prominently flared wheel arches draw the eye to a track width specific to the BMW M6 Gran Coupé . The characteristic M gills, aerodynamically optimized exterior mirrors, standard BMW Individual High-gloss Shadow Line package and exclusive 20-inch M light-alloy wheels in double-spoke design underline the car’s distinctive appearance, as does another M signature – twin exhaust tailpipes positioned on the outer edges of the rear apron. Also integrated into the rear apron, and charged with the task of optimizing the exit of airflow from the car’s underbody, is a diffuser made of carbon fiber composite.
Carbon fiber composite, an extremely lightweight, impressively strong high-tech material is used in the construction of the car’s roof panel as well. Here, the visible carbon structure provides an eye-catching feature, as does a dynamic recess in the center of the roof. This recess is referenced stylistically inside the car, the anthracite-colored Alcantara headliner gaining a central section in leather.
The interior of the new BMW M6 Gran Coupé brings together the incomparable combination of the driver-oriented cockpit design of a sports car with the spaciousness and luxurious feel of a premium automobile. Merino Extended leather upholstery, door sills with “M6” lettering, an M driver’s footrest, exclusive carbon fiber interior trim and the headliner in Anthracite Alcantara and Leather are all standard equipment, as is the iDrive control system with a 10.2-inch Control Display. This screen is centrally positioned and like the controls in the central section of the instrument panel, slightly oriented towards the driver.
The M instrument cluster with black-panel technology includes classic circular instruments in traditional BMW M car style, with red needles and white illumination, as well as model-specific displays and the M logo on the rev counter. The shift program currently selected and gear engaged are shown in the center of the instrument cluster. Feedback from the drive and chassis settings are also displayed in the instrument cluster under the tachometer.
The new BMW M6 Gran Coupé will reach Canadian BMW showrooms in Summer, 2013. Pricing, final technical specifications, fuel economy figures and standard and optional equipment will be announced closer to the market launch date.
