- BMW M6 Convertible, 2013
Out of a passion for elite performance and an appreciation of exclusive style comes the allure for which M Automobiles are renowned - and which can now be experienced in two new forms. The new BMW M6 Coupe and BMW M6 Convertible offer top-class performance attributes and an ambience defined by luxury and innovative comfort features. In so doing, the high-performance sports cars developed by BMW M GmbH exude a level of poise and assurance unmatched in the premium segment of the executive class - and reflected authentically in the expressive design of the two models. The precise interplay of their high-revving V8 engine with M TwinPower Turbo technology and 412 kW/560 hp, a seven-speed M Double Clutch Transmission with Drivelogic, Active M Differential, model-specific chassis technology, an ideal weight balance and optimised aerodynamic properties serves up a particularly full-blooded M experience.
The conceptual harmony characteristic of M Automobiles also incorporates the specific features of the two models' body structures. The new BMW M6 Coupe has a dynamically contoured, lightweight roof made from carbon fibre- reinforced plastic. The new BMW M6 Convertible, meanwhile, is fitted with a high-quality soft-top, complete with eye-catching "fin" styling and fully automatic opening mechanism. All of which allows the driver and passengers to enjoy the dynamic performance of a high-performance sports car in harmony with the natural forces of the sun and wind.
The motor sport technology in the new BMW M6 Coupe and BMW M6 Convertible paves the way for imposing performance on the race track, but also treats the driver to a captivating driving experience on everyday journeys from A to B. The BMW M6 Coupe sprints from 0 to 100 km/h (62 mph) in 4.2 seconds, the BMW M6 Convertible in 4.3 seconds. However, the dynamic character of both models is also defined by their mid-range agility, the precision of their turn-in and traction when accelerating out of corners, their precisely controllable handling under intense lateral forces and their stopping capability. The latest innovation designed to optimise the handling of the new BMW M6 Coupe and the new BMW M6 Convertible in highly dynamic driving situations are the M carbon-ceramic brakes, offered as an option for the first time.
Another attribute unmatched by any rival is the leap forward in efficiency that comes with the new editions of the two high-performance sports cars. The new BMW M6 Coupe records average fuel consumption of 9.9 litres per 100 kilometres (28.5 mpg imp) and CO2 emissions of 232 grams per kilometre in the EU test cycle. The equivalent values for the new BMW M6 Convertible are 10.3 l/100 km (27.4 mpg imp) and 239 g/km. Despite a 10 per cent increase in engine output and a 30 per cent jump in peak torque - to 680 Newton metres (502 lb-ft) - fuel consumption and CO2 emissions have been reduced by over 30 per cent in both cases compared with their respective predecessors.
Design: athletic aura, powerfully taut surfaces, elegant lines.
Classical proportions, the sporty yet elegant lines of the BMW 6-Series and the familiar design language of BMW M Automobiles form the foundations for the eloquent body design of the BMW M6 Coupe and BMW M6 Convertible. Powerfully taut surfaces and precise contours underline the athletic aura of the two models, while standard-fitted Adaptive LED Headlights accentuate their progressive character. In addition, hallmark M styling cues add details which are influenced directly by technical considerations - such as the cooling air required, chassis geometry and aerodynamics - and thus further highlight the cars' outstanding performance attributes.
Both models are fitted with 19-inch M light-alloy wheels as standard. The forged wheels feature seven double-spokes in a two-tone finish, while the optional 20-inch M light-alloy wheels hint at reduced weight with their five intricate double-spokes.
Dynamic contours, lightweight material: the carbon fibre-reinforced plastic roof of the BMW M6 Coupe.
Like its predecessor, the roof of the new BMW M6 Coupe is made from carbon fibre-reinforced plastic as standard. The dark colouring of the roof gives the two-door car's silhouette an extremely elongated look, which is further emphasised by a dynamic recess in the centre of the roof. The use of the lightweight material for the roof allows the car's centre of gravity to be lowered, enhancing agility. BMW Individual High-gloss Shadow Line trim (standard) draws attention to this optimised weight balance, its dark colouring covering the side window borders (or the waistline in the case of the BMW M6 Convertible) and the base and lower section of the aerodynamically optimised M exterior mirror caps.
The exclusive looks of the new BMW 6-Series Convertible are underlined by the "fin" architecture of the high-quality soft-top roof. Projecting into the rear section, the fins accentuate the car's dynamically sweeping silhouette. The heated, vertical glass rear window, which is situated just behind the rear seats, retracts independently of the soft-top itself. The automatic opening and closing process for the roof can be activated both at a standstill and while on the move at speeds of up to 40 km/h (25 mph) using a button on the centre console. The optional Comfort Access allows the roof to be opened or closed by pressing the remote control button on the car key. It takes the roof 19 seconds to open and 24 seconds to close again.
The engine: high-revving V8 with M TwinPower Turbo technology.
The new BMW M6 Coupe and Convertible showcase their individual style with a raft of unique styling touches and tweaks to the character of the driving experience. But they draw the output required to serve up their inspirational performance from the same source: a high-revving V8 engine with M TwinPower Turbo technology, longitudinally mounted at the front of the car, whose power is channelled to the rear wheels via a seven-speed M Double Clutch Transmission with Drivelogic. This powertrain combines construction features taken directly from motor sport with innovations developed under the banner of Efficient Dynamics. Its globally unparalleled package of technology comprises two turbochargers working according to the twin-scroll principle, a cross-bank exhaust manifold, High Precision Direct Petrol Injection, VALVETRONIC variable valve timing and Double-Vanos continuously variable camshaft control.
The unmistakable, typically M performance characteristics of the 4.4-litre powerplant are defined by its lightning-quick responses and forceful, linear power delivery maintained into the higher reaches of the rev range. Indeed, peak torque of 680 Newton metres (502 lb-ft) is on tap between 1,500 and 5,750 rpm. The V8 achieves its maximum output of 412 kW/560 hp between 6,000 and 7,000 rpm and can spin on to 7,200 rpm. All of which means the rev band available in the new models to generate maximum performance is almost three times wider than that of the engine powering their predecessors.
Harnessing the high output to dynamic effect: the seven-speed M Double Clutch Transmission with Drivelogic.
Tuned seamlessly to the performance characteristics of the V8 engine, the M Double Clutch Transmission with Drivelogic converts the powerplant's impressive thrust extremely effectively into rapid acceleration. This capability is underpinned by the DCT design principle, which effectively combines two gearboxes in one housing - yet with virtually no size or weight penalty over a conventional manual transmission.
M DCT Drivelogic offers the driver three different shift programs, both in automated mode (D) and in manual mode (S). In addition, the electronics also provide a Launch Control function ensuring unbeatable acceleration from a standing start, Low Speed Assistance for easier low-speed operation, and the Auto Start-Stop function for increased efficiency. The new BMW M6 Coupe and the new BMW M6 Convertible are equipped as standard with a newly developed M leather steering wheel, complete with multifunction buttons and fixed gearshift paddles.
Active M Differential delivers outstanding traction in dynamic driving situations.
The new BMW M6 Coupe and new BMW M6 Convertible also impress by offering optimum traction in tricky road and weather conditions and under dynamic acceleration out of corners. Working behind the scenes to this end is an innovative variable locking differential in the rear differential.
The Active M Differential allows the engine's power to be split precisely and quickly between the left and right rear wheel according to the requirements of the driving situation at any particular moment. An electronically controlled multi-plate limited-slip differential helps to reduce the rotational speed differences between the rear wheels, which is needed to optimise traction. The Active M Differential control unit is linked up to the DSC stability control system, allowing every driving situation to be precisely analysed and a loss of traction at one wheel to be detected at an early stage. The locking effect generated in response can be varied between 0 and 100 per cent.
M-specific chassis technology, Dynamic Damper Control, M Servotronic, DSC with M Dynamic Mode.
The chassis of the new BMW M6 Coupe and new BMW M6 Convertible has been developed to M specification and therefore combines outstanding performance attributes with the comfort-enhancing features drivers appreciate on an everyday basis. Like the integral rear axle, whose subframes are bolted rigidly to the body, the double-wishbone front axle boasts specific kinematics and newly developed components made from forged aluminium. Chassis mountings using large panels at the front and rear axle ensure dynamic forces are passed evenly through to the body. Through enthusiastically driven corners, this helps to noticeably reduce the roll movements triggered by bumps in the road surface. Both the construction of the chassis and its bespoke tuning for each model are defined by in-depth expertise from the race track and have been optimised during extensive testing on the Nürburgring'sNordschleife circuit.
The standard equipment of both models also includes electronically controlled dampers. The M-specific Dynamic Damper Control system adjusts damping force electrohydraulically to provide the required responses for the driving situation at hand and fulfil the wishes of the driver. A choice of three settings allows drivers to adjust the damper characteristics to their needs and preferences.
The hydraulic rack-and-pinion steering ensures unbeatable precision and a high degree of comfort. This system has a variable ratio, which enhances straightline stability and reduces the number of steering wheel turns required when parking and turning off a road. The likewise standard Servotronic speedsensitive power assistance is specially tuned to M specification and enables drivers to choose a personal configuration with the help of three set-up options.
In addition to applying brake impulses and reducing engine output to stabilise the car, the DSC stability control system of the two high-performance sports cars also employs the services of the Anti-lock Braking System (ABS), Cornering Brake Control (CBC), Dynamic Brake Control (DBC), Brake Assistant, the Brake Drying function and Start-Off Assistant. M Dynamic Mode (MDM) can be activated to override the basic setting by pressing the DSC button. By raising the intervention thresholds of DSC, this mode makes it easier to move off on snow or loose sand with slightly spinning driven wheels. MDM mode also paves the way for the familiar M self-steering response. "DSC Off" mode can likewise be activated at the touch of a button.
An innovation designed to deliver precise handling: M carbon-ceramic brakes.
The latest version of the compound high-performance braking system helps give the new BMW M6 Coupe and new BMW M6 Convertible outstanding stopping power. Its stand-out features include even lower weight, excellent feel and fade-free performance even under heavy loads. The diameter of the inner-vented and perforated brake discs is 400 millimetres at the front and 396 millimetres at the rear. The six-piston fixed-calliper brakes at the front axle - painted dark blue metallic and complete with the M logo - are radially bolted to the pivot bearing.
As an alternative to the standard compound high-performance braking system, M carbon-ceramic brakes make their debut in the new BMW M6 Coupe and new BMW M6 Convertible. They are available in conjunction with 20-inch M light-alloy wheels and feature brake discs measuring 410 millimetres in diameter at the front axle and 396 millimetres at the rear. Made from a new type of carbon-fibre compound ceramic, the discs boast even greater resistance to heat and combine this with significantly reduced rotating masses. The innovative material also displays exceptional resistance to wear.
The optional M carbon-ceramic system also sees six-piston fixed-calliper brakes at the front teaming up with single-piston floating-calliper brakes at the rear. The callipers can be identified by their special gold-coloured paint finish.
Lightweight design, seamless occupant protection.
An intelligent blend of materials also gives the body structure impressive strength coupled with extremely low weight. As with the use of CFRP for the roof of the new BMW M6 Coupe, the choice of materials for all other body components slots into the all-round lightweight design strategy. The doors and bonnet of the two high-performance sports cars are made from aluminium, the front side panels from thermoplastic. In addition, their boot lids and - in the case of the BMW M6 Convertible - also the roof cover are made from the glass-fibre composite material SMC (Sheet Moulding Compound).
A weight-to-power ratio of 3.3 kg/hp for the new BMW M6 Coupe and 3.5 kg/hp for the new BMW M6 Convertible is a significant improvement over the predecessor models.
Robust load-path structures, large and precisely defined deformation zones and highly efficient restraint systems provide the basis for a high level of passive safety in both models. The safety equipment fitted as standard includes front and side airbags, side curtain head airbags for both rows of seats in the new BMW M6 Coupe, and front airbags and head-thorax side airbags integrated into the seat frames of the new BMW M6 Convertible. The soft-top model also benefits from roll-over bars made from high-strength aluminium. Both models also come with three-point inertia-reel seat belts on all seats, belt force limiters and belt tensioners for the front seats and ISOFIX child seat attachments in the rear.
The two high-performance models are designed as four-seaters, and space in the rear compartment has increased substantially compared with the predecessor models. The load capacity of the new BMW M6 Coupe stands at 460 litres. The new BMW M6 Convertible, meanwhile, can accommodate 300 litres of luggage in the boot with the soft-top down and 350 litres with it closed.
Individual set-up configuration, two M Drive buttons on the steering wheel.
Also contributing to the familiar M feeling is the model-specific interior design whose stand-out features include newly developed M sports seats and an M-specific cockpit, along with buttons to adjust the DSC mode, engine performance characteristics, damper mapping, M Servotronic responses and shift program. Individually configured settings can be saved by means of two M Drive buttons on the steering wheel and called up as required.
The BMW Head Up-Display with M-specific information along with an extensive range of other driver assistance systems from BMW ConnectedDrive, such as Park Distance Control, rear-view camera, High Beam Assistant, Speed Limit Info, Lane Change Warning, Lane Departure Warning, Surround View and BMW Night Vision with pedestrian recognition. The choice of equipment options also includes M multifunction seats, the navigation system Professional and the Bang & Olufsen High End Surround Sound System.
