Thanks to the internets, we've seen this car coming for quite some time. It's proving to be harder and harder for the Bavarian manufacture to not get anxious about adding a car to their "M" line-up. This latest addition makes the CLS63 fans pull a double take when they see the new M6 Grand Coupe across the street.
The car possesses a complete "M" overhaul, not just a catalog checklist. A 4.4L M TwinPower Turbo V-8 with 560hp (at 5700-7000rpm) and 500 lb-ft (between 1500-5750rpm) is nestled under the hood and pushes the power directly to the rear wheels, making this the most powerful engine ever fitted under an M production car. Although the company hasn't hinted toward a manual gearbox (as more companies seem to shy away for this sort of thing) it does come with a silky smooth seven-speed M-Double Clutch Transmission (M-DCT). Lifted from its cousins the M5 and M6 Coupe. The rev-limiter receives a boost of 200rpm topping out at 7200rpm for even more crackle and pop between high-speed downshifts. 0-60 is gobbled up in 4.1s and top speed is limited to 155mph.
The M TwinPower technology of the new V-8 engine also includes BMW's Double VANOS 1 infinitely-variable valve timing system which optimizes the engine's efficiency and generates high torque at low engine revs. In addition, a volume-controlled oil pump and a range of other EfficientDynamics measures deliver an extra boost to efficiency.
The Active M Differential in the new M6 Gran Coupe is an electronically controlled multi- plate limited-slip differential programmed to optimize traction, stability and sporting character. The locking force within the differential is varied continuously between 0 and 100%. The data recorded by DSC sensors is provided to the Active M Differential whether the stability control system is in MDM mode or is switched completely off. The ABS system retains full functionality in all situations.
The suspension system is composed of BMW's ever popular M Dynamic Damper Control (DDC). This is electronically controlled shock absorbers that use electro-hydraulic damping force adjustment to provide the perfect set up for nearly any situation. Modes include Comfort, Sport and Sport Plus, which increase stiffening rate of the suspension from city street cruising to canyon carving and track days (respectively).
At the touch of a button, the driver can also select from three settings for the M-specific Servotronic speed-sensitive hydraulic power steering. The default Comfort mode keeps steering forces reasonable when parking or maneuvering, but still provides the M brand's hallmark direction-changing precision at higher speeds. Sport ensures the driver enjoys more intense feedback across all speed ranges. Sports Plus is the lowest level of steering boost that can be selected.
High-Performance M brake systems come in two flavors. Standard brakes are constructed of aluminum hubs and cast iron vented/cross drilled massive 400mm rotors up front and 396mm out back. The ever-popular six-piston caliper, 410mm (front) rotors and floating single-piston 396mm (rear) rotors M Carbon-Ceramic brakes are optional and, as we've tested, are well worth their weight in gold - ironically the price for a set as well.
The exterior receives the iconic M treatment as well. The front air-dam is comprised of large intakes, optional Adaptive LED Headlights and of course the M kidney grille design, which is a one-off for this model. Considering the M6 Grand Coupe is 4.45" longer than the M6 Coupe its sweeping low roof-line and flow seamlessly into the shoulders for a tone athletic look. Speaking of the roof, its now finished in the new M highlight feature, carbon fiber composite. Seeing as no M performance model would worthy of the badge without a wider track, the fenders have been flared to house the exclusive 20" M light-alloy double-spoke wheels. Twin exhaust tailpipes are pushed to the outer edges of the rear bumper, which has also received the M design treatment.
Piloting the car in style seems to be what all the kids are doing these days, and BMW made sure your experience in the M6 Grand Coupe goes above and beyond your expectations. M sport seats are fitted for the diver and passenger and are available in Merino Extended leather trim. The rear offers three-seats that is capable of a 40/60 split for cargo flexibility. M driver's pedals, carbon-fiber trim, exclusive Anthracite Alcantara headliner and a massive 10.2" iDrive control system display help round off the full leer-jet treatment.
On the left-hand steering wheel spoke, the driver has two M Drive buttons which can be used to call up a pre-configured setup for the car. For example, the driver can save a sporty configuration on the "M1" button and a track focused setup (with all driver aids shut off) on the "M2" button. The set-up selected will remain activated until it is either cancelled by pressing the button again or the driver switches to another M Drive setting. Once the system has been switched off - as when the engine is started - it reverts back to the default configuration. The M Drive system in the new BMW M6 Gran Coupe allows the driver to adjust no fewer than six parameters: the engine management, the response of the Servotronic steering system, the M-DCT shift program, the DSC mode, the responses of DDC and the information in the Head-Up Display.
While the company has been in consumed in readying there "i" concepts for production, it's encouraging to know they haven't left out their petrol performance clients in the process. After all, its gear heads like us that have developed a love affair with the brand for giving us responsive horsepower models that have us begging for more. Stay tuned as we wait to flog one around Los Angeles and see how it stacks up against the competition.
