The
first BMW ALPINA B7 was offered as a limited edition for the 2007
and 2008 model years. 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 the
electronically-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
automobiles. The 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. The BMW ALPINA
B7 made its North American premiere at the 2010 Chicago Auto Show
in February, and will go on sale at authorized BMW Centers in
Spring of 2010.
ALPINA
and BMW. A history of synergy.
ALPINA
– a name famous in Europe and the wider world for putting a
particular performance accent on BMWs, though not yet so
well-known in North America. BMW – a name famous all over 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 automobiles.
The
concept in 1961: to take an already fine-performing BMW (which
also just happened to be a practical sedan) and making it perform
even better. By 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.
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.
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 its 3, 5, 6, X5 and X6
Series developed by BMW M, BMW’s own performance subsidiary. For
an ultra-performance version of the 7 Series – a vehicle defined
by luxury and generous interior space – something other than “M”
performance character was called for.
In
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 applies
this philosophy to the newest 7 Series to produce a luxury sedan
of stunning performance. “A 7 Series Beyond,” one might say.
The
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 -3- torque.
This
rear-wheel drive performance/luxury Sedan achieves 0-60 mph in 4.5
sec. With maximum torque available across an unusually broad
engine range, from 3,000 to 4,750 rpm, the B7 accelerates
effortlessly from virtually any speed. The two turbochargers
operate in parallel, with generously-dimensioned turbine vanes
measuring 44mm in diameter. All three intercoolers, the
low-temperature intercooler integrated into the radiator package,
as well as the 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 a 9.2:1 compression and a maximum
turbo boost of 1.0 bar. The result is a formidable 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 remarkably high levels of power and
capability in every driving situation.
The
ALPINA SWITCH-TRONIC transmission control offers tailored shift
characteristics for every driver and situation thanks to its Sport
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 wheel. This results in shifts which take
place in a few hundred milliseconds with minimal power
interruption. Ending in two polished double-tailpipes, the
stainless-steel ALPINA exhaust system offers up that deep and
sonorous yet not intrusive V8 sound that enthusiasts have come to
expect from ALPINA.

The
BMW ALPINA B7 builds on the state-of-the-art adaptive suspension
technologies of the 7 Series, including tuned Dynamic Damping
Control and Active -4- Roll Stabilization, to the demanding
requirements of a 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 is
technologically feasible. In pursuit of this goal, shorter and
uniquely calibrated springs reduce front and rear ride height by
15mm and 10mm respectively.
Dynamic
Damping Control and Active Roll Stabilization enable the driver to
select from three distinct suspension set-ups: Comfort, Normal and
Sport. These are intentionally calibrated to provide noticeably
different set-ups, influencing the characteristic of the dampers,
the Active Roll Stabilization as well as the parameters of the
power steering assist, throttle response algorithms and
load-reversal damping.
The
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 harshness of a purely
sports-oriented suspension.
The
light-weight 21” wheels, with their 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 285/30
R21 rear. The result is that the BMW ALPINA B7 captures an agility
associated with much smaller sedans, while preserving the ride
quality associated with the BMW 7 Series.
The
B7 sedan is 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. In true “form-follows-function” fashion, the ALPINA
front integrates the fresh-air requirements of the transmission
and engine oil coolers, which are separated out of the main cooler
module for improved efficiency. The spoilers reduce lift at the
front by 30% and rear by15%. The exhaust system’s two double
tailpipes are seamlessly integrated into the rear bumper. 
The
interior of the B7 sedan features ALPINA blue illuminated door
sill trims, the SWITCH-TRONIC steering wheel in hand-stitched
LAVALINA leather, and the Black- Panel LCD screen instrument
cluster branded with ALPINA. Exclusive interior luxury wood trim
in the form of Myrtle Burl, a knotted burl of the Laurel only
found on the Pacific Coast of the United States, provides a warm
and traditional ambience. Optional ALPINA Piano Lacquer interior
trim with its silver diagonal rhombs, offers a modern
alternative.
The
full complement of BMW 7 Series exterior colors remains available,
in addition to the signature ALPINA Blue metallic paint. Discreet
metal ALPINA emblems adorn the upper seatbacks of the standard
leather Comfort seats and are inlayed in the wood trim. An
additional ALPINA plaque indentifying the car is mounted on the
inner roof panel just ahead of the sunroof. Even the engine bay
carries a subtle signature by tidily presenting itself with a
newly-designed ALPINA engine cover.
