(from Alpina Press
Release) B7 BITURBO
With the new BMW ALPINA
B7 Bi-Turbo, ALPINA presents its fourth generation of automobiles
based on the BMW 7 Series. Prominent predecessors include the BMW
ALPINA B12 6.0 and B7, which raised the bar in the high-performance
luxury saloon segment. Newly interpreted and in every way
state-of-the-art, the B7 Bi-Turbo unites exclusiveness, athleticism
and comfort in perfect harmony.
Yielding exquisite levels of torque and power from the charged 4.4
litre V8, and in conjunction with the electronically-adjustable
suspension with active roll stabilisation, the B7 Bi-Turbo promises
to offer a spectrum of driving experiences so varied 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 Bi-Turbo
and impart it a distinctive appearance and powerful stance.
The Bi-Turbo model
designation that now graces this flagship BMW ALPINA saloon hints at
even more powerful and torque-laden performance over its
predecessor, while simultaneously improving upon fuel economy.
The fully-aluminium, 4395 cm3 V8 aggregate yields 507 peak
horsepower (373 kW) at a moderate 5500rpm, with a maximum torque of
700 Nm available between 3000-4750rpm.
Two especially for the ALPINA powerplant constructed turbochargers
with generously-dimensioned turbine vanes are responsible for the
forced induction. Thorough exploitation of the engine’s potential
was achieved by means of optimising the indirect intercooler
(air-water/water-air) with its short intake paths and flow-optimised
High-performance pistons are at work in the cylinders, carefully
developed to harmonise with a compression of 9.2:1 and a maximum
turbo boost of 1.0 bar. The result is a formidable specific output
of 115hp (85kW) per litre, with a maximum average compression of
20.1 bar, a benchmark even amongst established sportscars.
One look at the torque and power diagram is enough to highlight that
the B7 Bi-Turbo will accelerate fiercely and effortlessly from very
low revs. Peak torque is available from an unusually broad range of
rpm’s, ranging from 3,000 to 4,750 rpm. This wide powerband coupled
with the exquisitely geared ZF six-speed automatic sport
transmission pampers the occupants with remarkably high levels of
smooth drivetrain comfort in every driving situation.
The ALPINA SWITCH-TRONIC, which has been programmed to shift
exceptionally smooth and comfortable in Automatic mode, offers
different shift characteristics for every taste and situation thanks
to the additional Sport and Manual modes. Driving the B7 Bi-Turbo
becomes an altogether different experience when using the buttons
found on the back of the steering wheel for manually selecting the
gears of the automatic transmission. This ensures shifts take place
within a few hundred milliseconds and with only minimal interruption
to the transmission of power, favourably comparable even to the best
twin-clutch transmissions. As a result, the B7 Bi-Turbo sprints from
0-100 km/h in 4.7 seconds, vehemently pressing on to an
electronically-limited 280 km/h top speed.
Chassis & Suspension
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 intelligent way forward, yielding the best of what is
In pursuit of this goal, marginally shorter and uniquely calibrated
springs reduce front and rear ride height by 15mm and 10mm
respectively. Together with the 21” wheel and tyre 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,
imparting this large saloon with an agility usually only associated
with much smaller sports saloons. The light-weight 21” wheels, with
their new interpretation of the ALPINA CLASSIC wheel design, are
shod with an especially selected staggered MICHELIN tyre set-up:
245/35 R21 front and 285/30 R21 rear. Foregoing Run-Flat technology,
conventional tyres are used to ensure a supple, comfortable finesse
that is rare today.
ALPINA have integrated state-of-the-art electronic suspension
technologies, skilfully and subtly adjusting them to the demanding
requirements of our customers. As part of the B7 Bi-Turbo standard
equipment, the electronic suspension system with Dynamic Damping
Control and Dynamic Drive (active roll stabilisation) enable the
driver to select from three distinct suspension set-ups: Comfort,
Normal and Sport. The B7 Bi-Turbo offers the driver unheard-of
versatility, delivering on long-distance comfort just as readily as
on back-road pace, always with a maximum of enjoyment and safety.
At once dynamic,
graceful and potent - the silhouette of the B7 Bi-Turbo is
significantly influenced by the evolutionary new design of the 21”
ALPINA CLASSIC wheels. A turbine-like three-dimensional curve guides
each of the 20 spokes from the centre of the wheel to the rim, at
which point they have a milled surface. Depending on the angle of
the viewer, the rotational speed of the wheels and the light, the
appearance of these classic wheels is constantly changing. Of course
they continue to possess the refined tyre air valves, safely and
attractively hidden away behind the lockable wheel covers.
In true “form-follows-function” fashion, the typical 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 design of the front and rear spoiler
follows clearly aerodynamically-oriented interests, reducing lift at
the front and rear by 30% and 15% respectively. Left and right, the
exhaust system’s two double tailpipes are seamlessly integrated into
the rear valance and are witness to the B7 Bi-Turbo’s potency.
When climbing into the B7 Bi-Turbo, one immediately takes note of
the ALPINA door sill trims which are finely illuminated in blue. The
SWITCH-TRONIC steering wheel is gloved and hand-stitched in the
finest, most comfortable LAVALINA leather. In the driver’s line of
sight, red pointers over a field of blue dials grace the instrument
cluster, where a Black-Panel LCD screen is responsible for
communicating driver-important information.
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 and just as exclusive alternative.
