Alpina B7 will be powered by a twin-turbocharged 4.4-liter V-8 engine that delivers a total of 500 hp and 516 lb-ft of torque. The 0-60 mph sprint is made in 4.5 seconds.
B7 also features an electronically-adjustable suspension with active roll stabilization, with three different suspension set-ups: Comfort, Normal and Sport.
On the outside there is a deeper front air dam and rear decklid spoiler, sport exhaust system with two tailpipes integrated into the rear bumper and 21-inch, 20-spoke Alpina wheels. The interior is fitted with Alpina blue illuminated door sill trims, the SWITCH-TRONIC steering wheel in hand-stitched leather LAVALINA, and the Black-Panel LCD screen instrument cluster branded with Alpina.
BMW of North America announced today that the 2011 BMW Alpina B7 sedan will join BMW's product range of North America as the most dynamic 7 Series model. BMW Alpina B7 represents the second generation of ALPINA automobiles based on the BMW 7 Series to be offered in the United States. The first BMW Alpina B7 was offered as a limited edition for model year 2007 and 2008. Newly interpreted and based on the current BMW 7 Series platform, the B7 will again set the benchmark in terms of performance, refinement, technology, luxury and exclusivity.
Yielding exquisite levels of power and torque from the twin-turbocharged 4.4 liter V8, and in conjunction with electronics - adjustable suspension with active roll stabilization, the new B7 promises to offer a spectrum of driving experiences so broad as to be unheard of in this class of car. Evolution of the traditional 20-spoke 21 "ALPINA CLASSIC wheels underline the fresh design language found throughout the B7 and impart it a distinctive appearance and powerful stance.
Both short-and long-wheelbase models will be offered. BMW Alpina B7 will make North American premiere at the 2010 Chicago Auto Show in February, and go on sale at authorized BMW center in the spring of 2010. Pricing will be announced closer to the sales.
history of Alpina and BMW
ALPINA is a name famous in Europe and the wider world to use a particular performance accent on BMWs, though not yet so well known in North America. BMW is a name known throughout the world for motor vehicles of performance, quality, luxury and safety.
The two companies, both at home in the German state of Bavaria, have a long history of working together to produce special BMW car. Burkard Bovensiepen, son of the founder of ALPINA Business Machines and an enthusastic racing driver / engineer, began his automotive career path in 1961 by developing a dual-carburetor setup for the just-introduced BMW 1500 sedan. It was a predictive beginning: to take an already fine-performing BMW (which also happens to be a practical sedan) and making it perform even better.
In 1964, BMW had officially recognized ALPINA's contribution to BMW performance. Not long thereafter, Burkard Bovensiepen founded the ALPINA company - ALPINA Burkard Bovensiepen KG - that continues today, creating special versions of BMW automobiles that offer a particular brand of performance for discriminating auto enthusiasts. But outside the circle of BMW enthusiasts, ALPINA has kept a low profile in North America. In addition to racing versions of BMWs, ALPINA has developed a progression of BMW-based cars based on 3, 5, 6, 8, Z4 and Z8 models and offered them on a limited production basis. Alpina is located in the small Bavarian town of Buchloe, some 50 miles southwest of Munich, BMW's headquarters city and the capital of Bavaria.
The B7 is the newest manifestation of the unique BMW-ALPINA synergy - once again based on the BMW 7 Series luxury sedan. Currently, BMW offers ultra-performance models of 3, 5, 6, X5 and X6 Series developed by BMW M.
In the most recent models, ALPINA has concentrated on delivering very high levels of performance with moderate rpm ranges and automatic transmission. Most appropriately, the new BMW ALPINA B7 philosophy applies to the newest 7 Series to produce a luxury sedan of stunning performance. "A 7 Series Beyond," one might say.
power B7 sedan is equipped with BMW's twin-turbocharged 4.4 liter, all-aluminum, High Precision Direct Injection V-8 engine which has been enhanced by ALPINA and is capable of producing 500 (373kW) horsepower and 516 lb-ft (700nm) of torque . performance rear wheel / luxury sedan reaches 0-60 mph in 4.5 seconds. With maximum torque available across a very wide engine range, from 3,000 to 4,750 rpm, the B7 accelerates easily from almost any speed.The two turbochargers operate in parallel, with well-dimensioned turbine blades measuring 44mm in diameter. Thorough exploitation of the potential of the machine is achieved by means of optimizing the indirect intercooler with short intake paths and flow-optimized intercooler tracts. All three intercoolers, the low temperature coolant radiator integrated into the package, as well as two near-engine intercoolers are enlarged by approximately 35%, ensuring very high thermodynamic efficiency. High-performance pistons have been specified to withstand the thermodynamic forces created by compression 9.2.1 and a maximum turbo boost 1.0 bar. The result is a terrific specific output of 115hp (85kW) per liter, with a maximum average compression of 20.1 bar, a benchmark even amongst established sports cars.
This wide power band coupled with the six-speed sport automatic transmission gives the driver a very high level of flexibility and capability in every driving situation. control Alpina SWITCH-TRONIC transmission offers tailored shift characteristics for every driver and situation sporty and Manual modes. To manually select the gears of the automatic transmission, the driver may use buttons found on the back of the ALPINA-tailored steering. This resulted in the changes that occur within a few hundred milliseconds with minimal power interruption.
the latter polished dual tailpipes, the stainless steel ALPINA exhaust system offers up that deep and melodious yet not intrusive V8 sound that enthusiasts have come from Alpina.
Chassis and Suspension
BMW Alpina B7 based on the state of the art adaptive technology suspension of 7 Series, including tuned Dynamic Damping Control and Active Roll Stabilization, to the demanding requirements of high-performance sedan. Long gone are the days when a purely "hard and sporty" ride was a sought-after attribute of suspension set-ups. Striving for truly neutral handling continues to be the goal, yielding the best of what technology is feasible. In pursuit of this goal, shorter and uniquely calibrated springs reduce front and rear ride height by 15mm each and 10mm. Dynamic Damping Control and Active Roll Stabilization enable the driver to select from three distinct suspension set-ups: Comfort, Normal and Sport. It feels intentionally calibrated to provide a different set-ups, influencing the characteristic of the dampers, the Active Roll Stabilization as well as the parameters of power steering assist, throttle response algorithms and load-reversal damping. Sport-Plus mode automatically shifts the Dynamic Stability Control system into Dynamic Traction Control (DTC). This allows noticeably more slip at the driven wheels and delayed intervention by the traction control system.
Together with the 21 "wheel and tire combination, the suspension is at once sensitive to inputs and direct in its feel, yet free from the violence of a purely sports-oriented suspension. The light weight 21 "wheels, with a new interpretation of the ALPINA CLASSIC wheel design, are shod with a specially selected staggered Michelin PS2 tire set-up: 245/35 R21 front and rear 285/30 R21.
The result is that the ALPINA B7 captures an agility associated with much smaller sedans, while preserving the ride quality associated with the BMW 7 Series.Design spring 2011 BMW B7
The B7 sedan finished with ALPINA aerodynamic developments, including front and rear spoilers which not only enhance the appearance but also improve stability and performance at high speeds. True form follows function "fashion, the ALPINA front integrates the fresh air requirements of the transmission and engine oil coolers, which are separated from the main cooling modules to improve efficiency. The spoilers reduce lift at the front by 30% and 15% rear. The exhaust system two double tailpipes are seamlessly integrated into the rear bumper. Latest evolution of traditional ALPINA CLASSIC 20-spoke wheels gives the B7 a different appearance and powerful stance.
The interior of the sedan features ALPINA B7 blue illuminated door sill trims, the SWITCH-TRONIC steering wheel in hand-stitched leather LAVALINA, and the Black-Panel LCD screen instrument cluster branded with Alpina. Exclusive interior luxury wood trim in the form of Myrtle Burl, a burl of the Laurel only found on the Pacific Coast United States, provides a warm atmosphere and traditional. Optional Alpina Piano Lacquer interior trim with silver diagonal rhombs, offers a modern alternative.
Metal ALPINA emblems adorn the seatbacks silently over the standard leather Comfort seats and are inlayed in the wood trim. Additional plaque indentifying the car is mounted on the inside of the roof panel right in front of the sun.
