Once again the latest creation from Alpina sets new standards in terms of driving dynamics, aesthetics and exclusivity. Furthermore, the new BMW Alpina B6 Bi-Turbo Gran CoupÃ© features some awareness raising attributes, breaking new ground and exciting the senses in a special way.
The powerful 4.4 liter V8 Bi-Turbo engine develops 397 kW (540 hp), a mighty 730 Nm of torque and is mated to the excellent ZF 8-Speed Sport Automatic Transmission with Alpina Switch-Tronic for super smooth and harmonious power delivery. Coupled with BMW's xDrive technology and a performance-oriented layout of the all-wheel drive system, this drivetrain delivers exceptional performance. With a 0 - 100 km/h acceleration time of only 3.9 seconds, the new B6 Bi-Turbo Gran CoupÃ© is the fastest accelerating BMW Alpina to date!
Advanced electronic suspension technologies such as Dynamic Damper Control (electronically adjustable dampers) and Adaptive Drive (active roll stabilisation) work together with the fully variable torque distribution of the all-wheel drive system to achieve very neutral, agile driving dynamics which meet the highest demands on comfort and sportiness. Maximum traction, especially on slick road surfaces or in wintery weather make the B6 Bi-Turbo Gran CoupÃ© a perfect companion in all conditions.
The first 'four-door CoupÃ©' in the Alpina model line-up presents itself as an elegantly stretched athlete with powerful lines. The BMW designers have accomplished a masterpiece with perfect proportions. A in comparison to the 6 Series CoupÃ© 113 mm longer wheelbase connects short overhangs with an elegantly flowing roof line. The Alpina typical design features blend seamlessly and elegantly into the contours of the Gran CoupÃ© and accentuate its sporty, powerful appearance.
Finest materials serve the realisation of personal desires, exclusive paint finishes and unique wood interior trim underscore the stylish and luxurious design of every single B6 Gran CoupÃ©. Optional comfort features and networked driver assistance and information systems complement the extensive standard equipment on request.
The illustrious circle of cars that can effortlessly and confidently reach speeds of 300 km/h and more is particularly small. With a top speed of 318 km/h the new B6 Bi-Turbo Gran CoupÃ© is undoubtedly part of that circle, but it impresses equally with its finely balanced handling and smooth refinement.
DRIVE - REFINED PERFORMANCE, POWERFUL DELIVERY
The B6 Bi-Turbo Gran CoupÃ©'s 4.4 liter eight-cylinder engine develops 397 kW (540 hp) at a moderate 5200 to 6250 rpm, with a maximum torque of 730 Nm available between 2800 and 5000 rpm.
Two turbo-chargers, each feeding one of the two cylinder banks, with especially developed large diameter exhaust-turbines and respective -housings, allow this engine configuration to achieve a high power and torque output over a very broad rpm range and spontaneous throttle response at low rpm.
The high-performance indirect inter-cooler system (air-to-water/water-to-air) with short intake tracts and optimised air-flow consists of a large-volume low-temperature inter-cooler and two engine-near inter-coolers. Additional motor oil and water coolers are located left and right behind the front spoiler and ensure the overall thermodynamic efficiency of the engine.
Specific MAHLE pistons are designed to deal with temperatures and pressures associated with up to 1.2 bar charging and the engine's 10.0:1 nominal compression ratio. Altogether this set-up produces a specific output of 90 kW (123 hp) per litre and a mean total compression of 20.1 bar.
Direct injection and Valvetronic contribute to the B6 Bi-Turbo Gran CoupÃ©'s class-leading consumption and emission figures of just 10.4 l/100 km and 242 g/km CO2 in the Combined cycle measured according to ECE Norm.
TRANSMISSION - EIGHT-SPEED ALL-ROUNDER
Adapted and tested in co-operation with ZF, the advanced Switch-Tronic 8-Speed Sport Automatic Transmission is perfectly tailored to the power and torque of the B6 Bi-Turbo. It excels equally in the disciplines sport and comfort, playing a central role in infusing the B6 Bi-Turbo Gran CoupÃ© with Alpina typical characteristics.
In Automatic (D) Shift Mode the blend of eight speeds and plenty of torque makes for super smooth gear changes only a torque converter can provide. In this Mode, explicitly programmed for maximum comfort, the B6 Bi-Turbo Gran CoupÃ© glides effortlessly and efficiently at low rpm and high gears, offering unmatched cruising ability.
Using the Sport (S) Shift Mode the transmission becomes significantly more dynamic, gear changes are executed faster and feedback becomes more direct. The system allows for multi-simultaneous down-shifts in milliseconds, hereby the transmission will skip several gears depending on engine loads and rpm to select the most favourable gear for optimum acceleration.
The Manual (M) Shift Mode gives the driver full control of the transmission. The Alpina Switch-Tronic buttons are ergonomically mounted on the rear of the steering wheel, their actuation allowing the driver to shift up or down as required. A unique feature of the transmission software in Manual (M) Shift Mode in combination with the selection of Sport, Sport+ or DSC OFF Mode using the Drive Experience Control button is the deactivation of the automatic up-shift function. In this mode of operation the transmission will hold the selected gear up to maximum rpm's (electronically limited) and will not automatically up-shift into the next gear. This is desirable in certain driving situations, for example during especially dynamic driving on roads with multiple tight hair-pin corners.
Hardware modifications to the transmission, output and drive-shafts allow the total powertrain unrestrained power delivery. In combination with the single-cylinder fade-out and Alpina specific software modifications this eliminates the common reduction of torque required by the transmission in order to up-shift. This allows super-quick upshifts under full loads which are in no way inferior to mechanical transmissions and together with the all-wheel drive means the B6 Bi-Turbo Gran CoupÃ© requires only 3.9 seconds for the sprint from 0 - 100 km/h.
The all-wheel drive system exploits the technical potential of BMW's xDrive system and its intelligent and dynamic distribution of drive power which continuously and fully variable distributes torque between the front and rear axle within milliseconds for a maximum of traction and control.
The programming of the torque distribution control system, which is interconnected with the stability control and engine management system, is performance-oriented and increases driving agility and dynamics markedly - especially under lateral acceleration - while maintaining neutral handling. Besides allowing optimum traction under acceleration by eliminating slip induced losses, the system continuously monitors a wide range of sensory inputs - for example steering angle, lateral acceleration, yaw angle and speed - to distribute torque so as to achieve maximum safety in challenging conditions or when encountering sudden changes in road surface friction.
EXHAUST SYSTEM - PURE-BRED, SONOROUS, LIGHTWEIGHT
The B6 Bi-Turbo Gran CoupÃ© features a full stainless steel exhaust system with two Alpina trademark elliptical twin tailpipes. The character of the deep exhaust note is prominent but not intrusive. Active exhaust valves allow the balancing act between perceived dynamism and comfort on long journeys - the driver can influence the sound experience using the Drive Experience Control button. In Comfort Mode the exhaust valve is closed up to 2500 rpm and depending on load, in Sport Mode the valve is permanently open.
An optional high-tech and high-strength titanium exhaust system is available as an option. Developed in cooperation with Akrapovic, this light-weight exhaust system achieves a 45 % weight reduction compared to stainless steel.
CHASSIS - DYNAMIC COMFORT
BMW Alpina automobiles place special demands on their chassis and suspension - requiring high levels of comfort for relaxed cruising, light-footed and dynamic agility for purposeful driving as well as safe and neutral handling at high speeds.
The B6 Bi-Turbo Gran CoupÃ©'s chassis and suspension technology builds upon the basis of a double-wishbone front suspension and integral rear axle. Furthermore it utilises sophisticated electronic suspension technologies including Dynamic Damper Control (electronically adjustable dampers) and Adaptive Drive (active roll stabilisation). This allows the driver to change the chassis and suspension settings distinctly between Comfort+, Comfort, Sport and Sport+ using the Drive Experience Control button.
The Alpina specific calibration of dampers and stabilisers is tied into other system parameters including torque distribution, stability control, steering assistance and throttle response.
Stiffer springs and increased front wheel camber in combination with the 20" staggered wheel and tyre set-up result in direct steering response and precise handling irrespective of the chosen Drive Experience Control setting. The high performance MICHELIN Pilot Super Sport tyres, measuring 255/35 ZR20 (97Y) EL, E / A / 71 dB front and 285/30 ZR20 (99Y) EL, E / A / 73 dB rear, fore-go run-flat technology in order to maximise comfort and allow non-limited top speeds.
EXTERIOR and DESIGN - ELEGANCE MEETS FUNCTIONAL AERODYNAMICS
The Alpina typical design features blend seamlessly and stylishly into the surfaces and lines of the Gran CoupÃ©, accentuating its dynamic, powerful appearance. In particular the delicate, elegant design of the 20'' Alpina CLASSIC light alloy wheels complement the long, smooth proportions of the Gran CoupÃ©.
Although aesthetics play a central role, the design and shape of the exterior components is also subject to strict aerodynamics premises. The front spoiler with integrated, slightly forward positioned splitter directs more air over and around rather than underneath the vehicle thereby stabilising the front-end at high speeds. The design of the front spoiler ensures the effective flow of sufficient air to various radiator modules of the performance cooling-system, including inter-cooler, water and oil. Special NACA air channels at the front of the underbody suck cold air towards the high-performance brake system measuring 374 mm front and 345 mm rear. Together the front and rear spoiler significantly reduce uplift to almost zero.
INTERIOR and EQUIPMENT - EXCLUSIVE CRAFTSMANSHIP
