The new BMW ALPINA B7 Bi-Turbo impresses with class-leading performance figures in the segment of luxury performance sedans: from 0 to 100 km/h in just 3.7 (4.2)* seconds, with a top speed of 310 km/h Modern and perfectly matched suspension technologies offer an unrivalled breadth of driving experiences, characterized by sharp, dynamic handling and outstanding comfort.
Cutting-edge BMW engine technology and intensive development work carried out by ALPINA, means output and torque are raised to a whole new level in the BMW ALPINA B7 Bi-Turbo. The new 4.4 litre 8-cylinder engine with Bi-Turbo charging, petrol direct injection and Valvetronic delivers an impressive output of 447 kW (608 hp) between 5750 and 6250 rpm, while the maximum torque of 800 Nm is available from 3000 rpm. The resulting performance figures are remarkable – the new BMW ALPINA B7 Bi-Turbo with all-wheel drive accelerates in just 3.7 (4.2) seconds from 0 to 100 km/h, reaching a top speed of 310 km/h.
The power output of this high-tech engine unfolds smoothly and with impressive emphasis across the entire rpm range. Excellent throttle response and high torque ensure that even at low engine speeds driver inputs are immediately transformed into forward acceleration. In every situation there is a fascinating surge to the car‘s power delivery.
In addition to the depth of ALPINA’s engineering expertise a number of significant technical details are responsible for the engine’s power output and performance characteristics – especially with regards to air intake system, the intercooler and turbocharger configuration and the high-performance cooling system. The Bi-Turbo charging system comprises two specially developed turbochargers positioned in the V of the 8-cylinder engine. These feature optimized twin-scroll turbocharger housings and compressor wheels with enlarged inlet and outlet diameters. In combination with appropriately sized turbines this configuration ensures very effective use of exhaust gas energy even at low engine speeds. The result is a fast power build-up and more torque at low engine speeds for overall exceptional engine response. 670 Nm of torque is available at 2000 rpm.
The overall aim during the construction of the output related components of the ALPINA air intake system - from the so called raw air intake ducts to air filter housings and clean air intake manifold - was to achieve maximum de-throttling. All components of the high-performance cooling system are designed to remove bottlenecks and maximise effectiveness – special large-volume coolers are interconnected by large diameter hosing for maximum throughput. An indirect inter-cooler system (air/water/air) facilitates the implementation of short charge-air intake paths – with a main intercooler supplying the two large volume engine-near intercoolers. Together with additional external water coolers and a transmission oil cooler, the system ensures the thermodynamic stability of the V8 Bi-Turbo engine at all times even under the highest loads and ambient air temperatures. Inside the engine special Mahle pistons and NGK spark plugs are designed to deal with the temperatures and loads associated with 1.4 bar charging and a compression ratio of 10.0:1.
The stainless steel ALPINA sports exhaust system is responsible for a reduction in back pressure and weight, its sonorous sound is typically V8. Active exhaust valves allow the driver to influence the sound experience by switching between Comfort and Sport Mode. A typical ALPINA feature: the two twin tailpipes of the exhaust system are integrated elegantly and aesthetically into the rear apron.
Suspension and Chassis
The new BMW ALPINA B7 Bi-Turbo features the most advanced suspension technology, offering owners an exceptional range of driving experiences.
The central objective during suspension development was to retain the unparalleled long-distance cruising comfort of the predecessor while at the same time significantly sharpening the agility, handling and lateral dynamics commensurate to the power output of the new BMW ALPINA B7 Bi-Turbo.
The 2-axle air suspension system combined with Dynamic Damper Control and Active Comfort Drive with Road Preview guarantees the very highest level of driving comfort at all times while the Active Roll Stabilization minimises body roll during cornering. The rear wheel steering of the Integral Active Steering system gives the new BMW ALPINA B7 Bi-Turbo a level of dynamic performance and agility not previously associated with performance luxury sedans. The Driving Dynamics Control button serves as the central control with which to select the various parameters that influence the driving dynamics of the new BMW ALPINA B7 Bi-Turbo. It also features an Individual Mode, which can be used to combine specific settings independently of each other according to the driver’s preference.
With the Driving Dynamics Control used to select the appropriate Mode, the 2-axle air suspension system is primarily responsible for the exceptional level of ride comfort in the new BMW ALPINA B7 Bi-Turbo. It also allows the ride height to be adjusted up or down which in combination with the other suspension systems facilitates the choice of a decidedly comfort or sport orientated chassis set-up. Overall a maximum ride height adjustment range of 40 mm is available. At speeds above 230 km/h the ride height of the BMW ALPINA B7 Bi-Turbo is lowered by 20 mm. This operating state, which can be activated manually regardless of speed by selecting the special ALPINA Sport Mode, results in a lower centre of gravity thereby increasing agility and high-speed stability. Furthermore, the lower ride height results in increased front wheel camber for an even more direct turn-in when cornering. If necessary the ride height can also be raised by 20 mm up to a speed of 35 km/h in order to increase ground clearance.
The settings of the Electronic Damper Control, which controls both rebound and compression, are selected also using the Driving Dynamics Control. A broad range of ALPINA damper set-ups are available ranging from Comfort Mode for effortless and relaxed cruising to ALPINA Sport Mode for maximum dynamic performance.
For the first time, the new BMW ALPINA B7 Bi-Turbo features Integral Active Steering which in conjunction with the high-performance drivetrain and the all-wheel drive system* offers a dynamic driving experience par excellence. The Integral Active Steering combines a variable ratio electric steering system at the front axle with active steering on the rear axle whereby the wheels can turn a maximum of 3 degrees. Specially attuned to the ALPINA suspension and MICHELIN performance tyres the rear axle steers opposed to the front axle at low speeds for increased agility and dynamic handling, while steering with the front axle at higher speeds for maximum high-speed directional stability.
The new BMW ALPINA B7 Bi-Turbo is fitted with MICHELIN Pilot Super Sport tyres measuring 255/40 ZR20 at the front and 295/35 ZR20 at the rear, mounted on 8.5 x 20 and 10 x 20 ALPINA CLASSIC wheels respectively. New lightweight 21” forged wheels take the traditional 20-spoke ALPINA CLASSIC design in a new minimalistic and technical direction. Forging results in high-density and high-strength aluminium alloy which enables a weight-optimized construction that saves 2.5 kg of unsprung mass per wheel. The MICHELIN Pilot Super Sport tyres are specifically designed to meet the demands of high-performance sports cars. They contribute directly to the precise steering feel and handling of the new BMW ALPINA B7 Bi-Turbo while foregoing run-flat technology in the interests of improved ride comfort.
Comprising blue painted 4-piston fixed callipers and 395 x 36 mm discs on the front axle and floating callipers with 370 x 24 mm discs on the rear axle, the high- performance brake system provides outstanding stopping power and deceleration.
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 maximum traction and control. The programming of the torque distribution control, which is interconnected with the Dynamic Stability Control and the engine management system, is performance-oriented and it increases driving agility and dynamics markedly – especially under lateral acceleration – while maintaining balanced and 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. The DTC Mode of the Dynamic Stability Control offers a more rear wheel drive bias torque distribution for even more dynamic handling.
Power transmission in the BMW ALPINA B7 Bi-Turbo is taken care of by a new generation of the excellent 8-Speed Sport Automatic Transmission with ALPINA SWITCH-TRONIC. Further refined and adapted to the performance characteristics of the high-torque V8 Bi-Turbo in collaboration with ZF, the transmission offers exceptional driving comfort in all situations.
Extended gear steps and a total spread of 7.81:1 improve shift comfort and fuel economy. In Automatic Mode the combination of eight gears and high engine torque makes for relaxed, luxurious cruising at low engine rpm even when travelling at speed.
In Sport Mode the shift points are optimized for improved driving performance and gear changes are considerably more dynamic. It is also possible to activate a Launch Control function in this mode. For maximum dynamic performance, the driver selects the Manual Mode thereby actuating gear changes manually by using the SWITCH-TRONIC buttons on the back of the steering wheel. In addition to extremely fast shift times close to a tenth of a second, this mode also supresses forced upshifts in the engine speed limit range.
All components of the transmission such as the torque converter with lock-up clutch, the planetary wheel sets and the inner cooling are designed to specifically cope with the high torque output of the V8 Bi-Turbo engine. This means that no torque reduction is necessary during upshifts when utilising Launch Control or when using the sportiest configuration of the Manual Mode. This contributes significantly to the striking longitudinal dynamics of the new BMW ALPINA B7 Bi-Turbo with all-wheel drive and allowing it to sprint from 0 – 100 km/h in just 3.7 (4.2) seconds.
The transmission features the latest Comfort and Efficient Dynamics functions such as Connected Shift (use of navigation data for an anticipatory shift strategy based on traffic routing) and coasting (decoupling of the engine and transmission when coasting).
Stylish, elegant and commanding. The appearance of the new BMW ALPINA B7 Bi-Turbo is defined by athletic flair and elegance. The ALPINA design and aerodynamic elements emphasize its performance character, with the front and rear spoiler striking a harmonious balance and highlighting the powerful presence of the BMW ALPINA B7 Bi-Turbo.
The design blends form and function – the aerodynamic components reduce uplift on the front and rear axles to almost zero for maximum driving stability at all speeds. Openings at the front of the vehicle allow the precise and effective flow of air to the individual components of the high-performance cooling system. The iconic BMW kidney grille is fitted with an integrated air flap control system that adapts to the BMW ALPINA B7 Bi-Turbo’s cooling needs: when closed it further reduces the level of aerodynamic drag.
Engineering craftsmanship meets timeless design. The unmistakeable 20” ALPINA CLASSIC wheels with twenty spokes and concealed air valves give the powerful BMW ALPINA B7 Bi-Turbo a touch of elegance and lightness. In the interests of weight reduction and a striking technical appearance, the optional 21” ALPINA CLASSIC forged wheels with visible wheel bolts do not feature concealed air valves and wheel caps.
The ALPINA sports exhaust system features two elliptical twin tailpipes that reflect the performance of the new BMW ALPINA B7 Bi-Turbo and its powerful V8 engine. They are precisely integrated in the rear apron and give the rear a smooth, elegant look.
The exclusive paint finishes in ALPINA Blue metallic and ALPINA Green metallic are a hallmark feature reserved solely for BMW ALPINA automobiles. Other BMW and BMW Individual paint finishes are likewise available for the new BMW ALPINA B7 Bi-Turbo.
