The 2013 BMW 6-Series Gran Coupe - a new 4-door, 4+1 seat addition to the 6-Series line - successfully combines the stunning proportions, design and driving dynamics of the 6-Series Coupe with interior room and amenities for up to five passengers. Perfect proportions, precise lines and sleekly contoured surfaces give the BMW 6-Series Gran Coupe the unique ability to satisfy the driver who wants a luxurious and sporty coupe yet needs a car capable of carrying four adults in comfort and luxury. The BMW 6-Series Gran Coupe will be offered as three distinct models in the US. The TwinPower Turbo 6-cylinder BMW 640i Gran Coupe is the initial model and arrives in late June 2012 with an MSRP of $76,895. Later in the summer, the TwinPower Turbo V-8 BMW 650i Gran Coupe and the all-wheel drive BMW 650i xDrive Gran Coupe will join the range. These models will be priced at $87,395 and $90,395 respectively (all prices include $895 Handling and Destination

Sporting a length of 197 inches (5,007 mm) and wheelbase of 116.8 inches (2,968 mm), the Gran Coupe is 4.4 inches (111 mm) longer than its 2-door coupe sibling. A significant part of this extra length has been used to enhance seating comfort for the rear passengers. The BMW 6-Series Gran Coupe is also 74.6 inches (1,894 mm) wide and stands 54.8 inches (1,392 mm) in height. For comparison purposes, the Gran Coupe is 4.0 inches (102mm) longer, 1.3 inches (34mm) wider and 2.8 inches (72mm) lower than the BMW 550i.

Upgraded TwinPower Turbo 6-Cylinder powers the BMW 640i Gran Coupe.
The inline 6-cylinder engine (N55HP) in the new BMW 640i Gran Coupe will impress performance-minded drivers with its effortless power, exceptionally fast-revving temperament, outstanding refinement and exceptional fuel efficiency. The N55 has been setting standards from the start, as the pioneer of a new generation of engines in which BMW TwinPower Turbo technology with High Precision Direct Injection and VALVETRONIC variable valve timing plus a twin scroll turbo made its debut.
Thanks to intensive fine-tuning of the engine, BMW's engineers have managed to extract additional performance from the engine while maintaining its exceptional fuel efficiency. With a maximum power rating of 315 hp (225 kW) at 5,800 to 6,000 rpm, the 3.0-liter 6-cylinder engine reflects the sporty personality of the BMW 640i Gran Coupe and helps this automobile deliver brilliant performance. The high peak torque of 330 lb-ft, on stream between 1,300 and 4,500 rpm, ensures that the power is effortlessly and instantly delivered.

As a result, the BMW 640i Gran Coupe can show off its prowess with a 0 to 60 mph sprint time of just 5.4 seconds. Top speed is electronically governed at 155 mph (250 km/h). All this extra performance comes with exceptional fuel economy and low emission figures. EPA fuel economy ratings will be available closer to the US on-sale date, however the estimates should be in line with those of the BMW 535i Sedan which boasts an impressive 20 mpg city/30 mpg highway/24 mpg combined.
BMW's widely lauded TwinPower Turbo V-8 engine is updated with more performance and more efficiency in the 650i Gran Coupe.
The 4.4-liter V-8 engine (N63) that powers the current 650i models receives an upgrade for the new 650i Gran Coupe. The unique "reverse-flow" engine, whose two turbochargers are positioned in the V-area between the cylinder banks is well known for producing an instantaneous and sustained wave of power, making it a delight for the enthusiast driver. This new version of the engine adds BMW's VALVETRONIC variable valve timing to the list of specifications. As a result, the new version of the engine (N63Tü) develops a maximum 445 hp between 5,500 and 6,000 rpm (a 45 hp increase), and makes peak torque of 480 lb-ft between 2,000 and 4,500 rpm (a 30 lb-ft increase).
The new BMW 650i Gran Coupe completes the sprint from 0 to 60 mph in 4.5 seconds. Top speed is electronically limited to 155 mph. This engine also boasts extraordinary efficiency for a model in its output class. EPA fuel economy ratings for this model will be available closer to the on-sale date in summer 2012.
When the V8 is combined with the xDrive intelligent all-wheel-drive system, its power is converted into even more intense and dynamic acceleration. The electronically controlled power split between the front and rear wheels optimizes not only traction and stability, whatever the weather and road surface conditions may be, but also the agility of the Gran Coupe 650i xDrive Gran Coupe, whose sprint time from 0 to 60 mph is just 4.3 seconds

8-speed Sport Automatic Transmission.
The 8-speed Sport Automatic transmission in the new BMW 6-Series Gran Coupe boasts a perfect combination of speed, flexibility, sportiness, and efficiency. What sets it apart are its minimal torque converter slip and rapid gear changes. An innovative gear set configuration allows this transmission to offer eight gears, maximizing acceleration at any road speed, yet allowing the driver to conserve fuel by cruising at low revs. Befitting the Gran Coupe's sporting character, the driver can choose to select gears manually via shift paddles on the standard Sport leather steering wheel.
In addition to the efficiency of the engine and 8-speed Sport Automatic transmission, an extensive range of BMW EfficientDynamics measures contribute to reducing fuel consumption and emissions. Brake Energy Regeneration, engine Auto Start-Stop, on-demand operation of ancillary components, intelligent lightweight construction and extensive aerodynamic refinement collaborate to ensure maximum efficiency.
Chassis Management and optional Integral Active Steering.
Cutting-edge chassis technology gives the new BMW 6-Series Gran Coupe the tools to provide both sporty handling and exceptional comfort. The double wishbone front suspension and the multi-link rear suspension are made predominantly from aluminum. The chassis is geared to the requirements of drivers with sporting intentions, although the dampers also respond sensitively to bumps in the road surface under high lateral acceleration. The optional Active Roll Stabilization works in concert with the standard Dynamic Damper Control to offer the driver even more precise responses and perfectly flat cornering ability. The electronically controlled shock absorbers adapt to the road surface and the driver's style to perfectly control the car's body motions.

The electronically controlled damper system in the new BMW 6-Series Gran Coupe adjusts compression and rebound settings continuously and independently. For example, a stiff chassis setting can be combined with comfortable responses to unevenness in the road surface. The control unit of the damping system processes the data supplied by sensors on the vertical motion of the wheels as well as the ride height of the car. The driving speed and the damper setting chosen by the driver are also taken into account in calculating the damping force required for each individual wheel to even out body movements. This data is fed back to the shock-absorber units at intervals of just 2.5 milliseconds.
The optional Active Roll Stabilization feature reduces body roll in corners and in sudden changes of direction, or transitions. Sensors calculate the amount of body roll based on the driving situation at hand, and this is then counteracted quickly and precisely by hydraulic rotary actuators in the front and rear anti-roll bars. The result is flatter cornering inspiring greater confidence for the driver as well as greater comfort for the passengers during spirited drives. The power steering features standard Servotronic vehicle-speed sensitive assistance, and serves up the familiar BMW recipe of precision, comfort and linear response.
The Gran Coupe is also available with Integral Active Steering. This system (also available on the 6-Series Coupe and Convertible) combines the Active Steering system for the front suspension with a steerable rear suspension. Precisely harmonized steering angle movements of both front and rear wheels create a virtual lengthening or shortening of the vehicle's wheelbase, which fosters both greater high-speed stability and enhanced maneuverability for parking and city use
Brakes, Wheels, and Tires.
The lightweight floating-caliper brakes feature vented discs and Dynamic Stability Control. DSC brings together technology such as the Anti-lock Braking System, Dynamic Traction Control, Cornering Brake Control, Dynamic Brake Control, the Start-off Assistant, the automatic Brake Drying function and Brake Fade Compensation. Standard equipment also includes 8.0 x18-inch light-alloy wheels, with all-season runflat tires (size 245/45 R18) and a tire pressure monitoring system.
Driving Dynamics Control with ECO PRO mode: From most athletic to the most fuel-efficient driving modes - at the press of a button.
The new 6-Series Gran Coupe offers impressive driving dynamics combined with new standards of comfort in the premium segment. This is a result of superbly tuned suspension which achieves an astonishing balance between dynamics and comfort. On top of this, drivers are also able to vary the overall character of the car depending on the driving situation or to suit their personal preferences. As well as sportier or more comfortable drive settings, they can also opt for extra fuel efficiency. The different modes are selected using the new Driving Dynamics Control function including ECO PRO mode, which is standard on all 6-Series models. The driver can choose settings of COMFORT+, COMFORT, SPORT, SPORT+ and ECO PRO modes using the large rocker switch on the center console. Affected parameters include the tuning of the throttle response, power steering boost assistance, shock absorbers, automatic transmission shift characteristics and - if equipped - roll stabilization and Integral Active Steering. In SPORT+ mode, the Dynamic Traction Control mode of the standard Dynamic Stability Control system is activated, raising the thresholds for stability intervention in the most sport-oriented driving circumstances.
The new ECO PRO mode, on the other hand, supports an extra-efficient and economy-conscious driving style. It does this by changing the accelerator mapping so that the same pedal travel delivers less power than in the standard mode. Also in this mode, the automatic transmission control strategy is modified so as to upshift sooner and to delay downshifts, while intelligent energy and climate management reduces the mechanical power consumption and also the consumption of electrical systems such as heated mirrors and seats. But the biggest potential for improving fuel economy comes from the driver's own personal driving habits. Special displays in the instrument cluster let the driver know by how much the driving range is being extended, show fuel consumption history, or, with reference to the specific driving situation, provide tips and incentives on how to develop a more economy-conscious driving style. ECO PRO mode allows average fuel consumption to be reduced by up to 20%, with a corresponding increase in driving range

Design: Athletic elegance, natural sportiness.
The new BMW 6-Series Gran Coupe again heralds the arrival of an exceptionally sporty and exclusive 4-seater in the premium coupe segment. The new model's extra length and width over its 2 door model combine with its low height (2.8 inches lower than a 5-Series) to produce a strikingly low-set and powerful design. This new interpretation of the traditional BMW Coupe proportions is embellished by lines and surfaces inspired by the movement of waves. Flowing lines and harmonious curves create a feeling of athletic grace which underline the opulent character and elegant appearance of the four-door BMW.
The expressive front end is dominated by the large and slightly forward-slanting BMW kidney grille. The grille emphasizes the car's sporting pedigree with a broad, flat design, and creates a visual connection to the engine nestling behind. The kidney grille slats, angled slightly towards the top, lend additional emphasis to the front end's "shark nose" character. The contour lines of the hood converge towards the kidney grille, forming a V-shape which is continued by the contours of the headlights, kidney and wide air intake to give a road-focused look.
Powerfully flared wheel arches and the LED foglamps, placed well to the outside, accentuate the width of the front end. The lower air intake is split into three sections by model-specific L-shaped electroplated bars, which pick up the contours of the hood lines and BMW kidney grille to add extra intensity to the road-focused stance of the front end.
High-visibility innovation: Adaptive LED Headlights.
The new Gran Coupe is equipped with standard Adaptive Xenon headlights. An accentuating trim element cuts across the top of the hallmark BMW twin round headlights to produce the purposeful look familiar from other BMW models. The optional Adaptive LED Headlights, available as a stand-alone option or as part of the BMW Individual Composition Package, provide a fresh take on this established feature. In both cases, LED light rings for the parking lights and daytime running lights, which are flattened on the lower edge and overlapped at their top edge by an accent light - which also featuring LEDs. The result is a stunning, distinctively BMW showcase for the innovative light technology. In addition, they also generate the low beam and high beam light from the two light rings. The light sources are horizontal LED ribs positioned in the center of the light rings. This results in the brand's hallmark twin round headlight look being expressed even more strikingly - not only with the daytime running lights switched on, but also when the headlights are activated in the dark.
The Adaptive LED Headlights are, however, about more than just looking good; they also ensure the driver has optimum visibility. Their bright white light provides a bright and even illumination of the road ahead. From a color perspective, the light comes much closer to natural daylight than that created by conventional halogen or xenon headlights, lending even reflective objects far greater contrast. The cornering element of the Adaptive LED Headlights is also tailored to the car's speed, steering angle and yaw rate, allowing the pivot of the headlights to adapt automatically to the line of the corner. Meanwhile, a light source positioned specially in the headlight housing generates the cornering light which, at low speeds, ensures illumination of the road surface in the direction the car is turning. LED technology is also deployed for the turn signal indicators, each of which consists of eight LED units arranged in a row underneath the light rings. As well as enhancing visibility in the dark, the Adaptive LED Headlights also significantly improve the signaling effect of the car's lights.
Profile: Elegant roofline, powerfully curved surfaces.
With its long, powerfully contoured hood, set-back passenger compartment, long wheelbase and short overhangs, the BMW 6-Series Gran Coupe presents a fresh take on the hallmark BMW proportions. The Gran Coupe's distinctive appearance is dominated by its four-door layout, longer wheelbase than other BMW 6-Series models and likewise longer passenger compartment. The low, elegantly stretched roof line, which flows smoothly into the rear end, is a similarly eye-catching and distinctive feature of the new model's silhouette.
The combination of sportiness, style and luxury is particularly clear when viewed from the side. Longer side window surfaces than those found on the two-door BMW 6-Series models hint at the extra space available in the rear compartment. Side windows extending far back into the C-pillar give the passenger compartment the low-slung, stretched look typical of a BMW Coupe. The more generous greenhouse also allow light to flood the interior, further enhancing the feeling of space inside and all-round visibility for the rear passengers. High-quality Chrome Line Exterior surrounds for the side windows complement the coupe style window line. The hallmark BMW Hofmeister kink at the transition to the C-pillar is given an extra touch of style in the form of etched "Gran Coupe" model lettering set against a sporty texture in the rear section of the side window.
Powerfully flowing surfaces - which open out as they extend back from the front end and stretch over the full length of the body before feeding into the muscular rear end - give the BMW 6-Series Gran Coupe a naturally sporty look. The character line streaming out from the gill on the front wheel arch takes in the door handle and runs the full length of the car, emphasizing the athletic elegance of its side view. Around the rear wheels, the surfaces below the character line push outwards, enhancing the impression of a powerful car with a strong, assured stance on the road. Plus, the light surfaces generated above the rear wheel arches draw further attention to the wide track and the power being channelled through the rear wheels.
Another character line, emerging from the curvature of the front wheel arch, drops down between the gill feature and the door, before levelling out and extending horizontally to the rear. The unbroken shadow surface above the side sill emphasises the car's muscular stance from the side.
Distinctive rear-end design: horizontal lines and clean surfaces.
Clearly structured surfaces and horizontal lines add further presence to the car's powerful rear end, which acts as a pointer to the BMW 6-Series Gran Coupe's impressive roadholding and the sporting nature of the vehicle concept as a whole. The lines of the rear end become noticeably broader as they blend into the wheel arches bulge. All of which gives the rear view an extremely low visual center of gravity. The conspicuously flared wheel arches spotlight the car's wide track and underline the horizontally structured character of the rear. The trunk lid and rear fascia both have flatter surfacing than their counterparts on the other BMW 6-Series models. The more clearly sculpted sill emphasises the overall volume of the rear end and brings striking details such as the rear lights and exhaust tailpipes more clearly into view.
The two-part, L-shaped rear lights share the contours of the car's BMW 6-Series siblings and each use a pair of LED light strips to generate the distinctive night-time look of a BMW. The third brake light is integrated into the roof and stretches the full length of the rear window.
Interior with BMW's traditional driver-oriented cockpit.
The interior of the BMW 6-Series Gran Coupe reveals the driver-focused cockpit design typical of the brand and a luxurious ambience for all those on board. The central section of the instrument panel is angled slightly towards the driver and the gear selector for the automatic gearbox, the Driving Experience Control switch and the activation button for the parking brake are all positioned on the surface of the center console which opens out towards the driver.
The standard Navigation System Professional and iDrive operating system come with 10.2-inch high definition display bordered by a galvanised chrome surround.
Long horizontal lines extending all the way through the interior of the BMW 6-Series Gran Coupe create a visual link with the second row of seats, emphasising the size of the interior. The elegant lines of the door trim, familiar from the other BMW 6-Series models, continue into the rear compartment, incorporating the B-pillar as a design element along the way. The sweeping design of the door panels flows harmoniously from the front doors via the B-pillars to the rear doors. The center console also stretches through to the rear. Precise contours help to create an intriguing contrast with the interior's soft, curvaceous surfaces, producing a vibrant and dynamic collage of forms.
The waistline surfaces of the doors form a subtly dynamic wedge shape, which extends into the luggage compartment cover. The dynamic character of the door surface design generates a feeling of depth which envelops the passengers in their seats, while the interplay of convex and concave surfaces evokes a sense of exclusive security.
