The V8 Bi-Turbo
accelerates the Touring from 0-62mph in 4.8s while 700Nm of torque
paired with the exceptional 8-speed Sport Automatic Transmission
with SWITCH-TRONIC means power is always readily available. Modern,
dynamic and well toned in appearance – the B5 Bi-Turbo Touring has
all the right visual qualities to make it the perfect companion for
business and leisure.
BMW ALPINA B5 BITURBO SALOON AND
TOURING
THE POWERTRAIN – First Class
Performance And Economy
The all-aluminium V8
powerplant produces 507 horsepower (373 kW) at a moderate 5,500rpm,
with maximum torque of 700Nm from 3,000 to 4,750rpm. „Bi-Turbo“
refers to two turbo-chargers configured in parallel, each feeding
one of the two cylinder banks. Specially developed large diameter
exhaust-turbines allow this engine configuration to provide both
exceptional power output and an abundance of torque over an
especially broad rpm range while maintaining excellent throttle
response at low rpm.
The comprehensive
high-performance cooling system comprises an indirect inter-cooling
system (air-to-water/water-to-air) with short intake tracts and
increased inter-cooler flow. The systems excellent thermodynamic
efficiency is guaranteed by a large-volume low-temperature
inter-cooler radiator, as well as two water-to-air inter-coolers
placed close to the engine. High-performance MAHLE pistons are
designed specifically to deal with temperatures and pressures
associated with up to 1.0 bar charging and the engine’s 9.2:1
nominal compression ratio. Altogether this results in an impressive
specific output of 115.3 horsepower (85kW) per litre and a mean
total compression of 20.1 bar.
Direct injection and
Double-VANOS contribute to the B5 Bi-Turbo’s class-leading
performance, emissions and economy in this segment: 10.8l/100km /
26.2mpg (Touring: 10.9l/100km / 25.9mpg) and 252g/km (Touring:
255g/km) CO2 (Combined, 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 sets a new benchmark. With ALPINA’s
philosophy the guiding credo, our engineers have spent thousands of
development and test hours ensuring that no other performance
automatic transmission comes close to providing this level of both
comfort and performance.
The blend of eight
speeds and plenty of torque makes for unparalleled comfortable gear
changes with no noticeable interruption to the delivery of power –
only the accompanying acoustics and the dynamic rev counter provide
feedback as to the workings of the transmission. 700Nm of torque
means the B5 Bi-Turbo excels at cruising along at speed in a high
gear at minimum rpm, benefiting both consumption and comfort.
Using the Sport (S)
Shift Mode a completely different character emerges: the
transmission is crisp and unmistakably immediate. The innovative
single-cylinder fade-out (known as 'Einzelzylinderausblendung‘ in
German), initially engineered for application in the ALPINA B6 GT3
race car, enables super quick up-shifts which take just
milliseconds. Depending on the load on the transmission, the
injection of fuel into a given cylinder is interrupted for a
fraction of a second, creating the required reduction in torque that
the automatic transmission needs for the up-shift. The advantages
versus the typical method of timing retardation are noticeably
quicker shifts, improved thermo-dynamic efficiency due to reduced
exhaust temperatures and lower fuel consumption. Each up-shift is
accompanied by a deep back-pressure burble.
The SWITCH-TRONIC
buttons, for use in the Manual (M) Shift Mode, are ergonomically and
unobstrusively positioned on the back of the steering wheel, and
allow the driver to take complete control of the transmission. The
system allows for multi-simultaneous down-shifts in milliseconds,
hereby the transmission will skip several gears depending on engine
loads and rpm. In this manner the 8-speed Sport Automatic
Transmission with ALPINA SWITCH-TRONIC reveals itself as extremely
multi-faceted, providing the right shift characteristic for any and
all situations.
The Automatic Up-Shift
function means that the transmission will up-shift into a higher
gear once a certain rpm threshold has been passed in the current
gear. In certain driving situations this may not be desired, for
example during especially sporty driving or for example when
encountering multiple tight hair-pin corners. The simultaneous
selection of either Sport, Sport+ or DSC OFF Mode using the Drive
Dynamic Control button and the selection of the M Shift Mode
(transmission) will deactivate the automatic up-shift funtion. The
transmission will hold the selected gear up to maximum rpm’s
(electronically limited) and will not automatically up-shift into a
higher gear.
The intelligent coupling
of state-of-the-art engine and transmission technologies give the B5
Bi-Turbo stunning performance figures: just 4.7 (Touring: 4.8)
seconds from 0-100km/h / 0-62mph are needed, on the way up to a top
speed of 307km/h / 191mph (Touring: 303km/h / 188mph). Massive
braking capability in the form of ventilated high-performance brakes
(front: 374mm/14.7in, rear 345mm/14.6in) ensures braking on par with
pure-bred sports cars.
SUSPENSION – Dynamic Comfort
The times when „properly
stiff“ suspensions were seen as a positive handling characteristic
are long gone. It remains a fact that a truly neutral set-up, even
at the limit, provides the best technical compromise. This is
achieved in part through shorter ALPINA springs and specific
transverse suspension arms which in combination result in an
optimised camber.
Together with 20“ wheels
and tyres this yields a very balanced and direct chassis set-up,
discarding a pure sport-orientated approach for an agile suspension
with precise turn-in. Mounted on the light-weight 20“ ALPINA CLASSIC
wheels are non-run-flat MICHLIN PILOT SUPER SPORT tyres measuring
255/35 ZR20 front and 285/30 ZR20 rear. Representing the latest in
ultra-high performance tyre technology available today, they feature
a running surface is made up of 2/3rds soft compound (centre) and
1/3rd hard compound (outside and flanks). This mixture makes for
excellent durability despite typical hard use in high-performance
vehicles yet provides very good grip in the wet. Enhanced tread
stability and a new flank reinforcement technology ensures the tyre
is less likely to suffer from spikes in temperature with a resulting
loss of grip in the dry.
To fulfil the seemingly
contradictory demands for comfort, everyday usability and sports car
like handling, the B5 Bi-Turbo is equipped with
electronically-adjustable dampers (Dynamic Damper Control and Drive
Dynamic Control). This system has been artfully calibrated by ALPINA,
and is tied into other system parameters controlling steering
assistance, torque cushioning and the Dynamic Stability Control
system. Featuring pronounced Comfort, Normal, Sport and Sport+
modes, the B5 Bi-Turbo transitions effortlessly from cultivated
luxury to thorough-bred sportiness. Light steering,
ultra-comfortable suspension and an imperceptibly shifting
transmission make the B5 Bi-Turbo an ideal partner in stop-and-go
traffic, when covering great distances or when encountering less
than perfect road surfaces. Yet at the touch of a button, the B5
Bi-Turbo will track through tricky corners and exciting sections of
road with an agility and light-footedness like no other in its
class.
An especially for the
BMW ALPINA B5 Bi-Turbo in co-operation between ALPINA and Drexler
Motorsport adapted limited-slip differential is available as an
option. This mechanical limited-slip differential improves traction
during dynamic driving and minimises slip by distributing torque and
power to the wheel with the most grip. The operation of the
limited-slip differential is permanent and independent from other
driving dynamic settings or systems. Significant characteristics
include: torque sensing multidisc differential with pre-tensioning;
active locking characteristic up to 30 % under load and 20 % under
trailing throttle; very reactive in sensing slip, harmonious
self-steering properties and excellent directional stability; motor
sport quality, forged gears, CNC milled housing, hand built.
DESIGN & INTERIOR – Classic
Craftsmanship Meets Modern Technology
The B5 Bi-Turbo presents
typical ALPINA virtues and design cues in a new and convincing
fashion, with a refreshing and dynamic appearance. Both the saloon’s
and the touring’s silhouette begins with an attention commanding
front that is powerful and confident, and ends with a harmonious and
elegant rear. The ALPINA trademark two double-ended-pipes are
artfully integrated into the rear valence which features a discreet
diffuser. The diffuser can be deleted as needed, should the customer
desire the optional ability to tow a trailer. In combination with
the rear spoiler (Saloon), the B5 Bi-Turbo’s total aerodynamic
package yields the highest levels of safety and stability,
especially at high speeds. The resulting reduction in lift,
speed-dependent, can reach a remarkable –60 % front and –30 % rear.
The interior reveals the expected discreet touches that suggest the
B5 Bi-Turbo’s exclusive pedigree. The standard equipment level is
comprehensive: leather interior, versatile and adjustable Comfort
seats, an excellent navigation system with Bluetooth preparation,
and Xenon headlamps all ensure the driver’s and passengers’
well-being. The hand-stitched LAVALINA leather SWITCH-TRONIC
steering wheel can be positioned exactly as needed to see the blue
ALPINA gauges with black-panel LCD technology, thanks to the
electrically-adjustable steering column. The classic ALPINA burled
Myrtle wood trim provides a warm ambience - found only on the USA’s
Pacific Coast it is cultivated from dedicated Laurel tree groves
grown for just this purpose. Optional ALPINA Piano Lacquer interior
trim with its silver diagonal rhombs, offers a modern and just as
exclusive alternative.
The interior’s warm
ambience and modern treatments foster a sense of well-being. For
those who would only award themselves that something unique,
exclusive volumes and the ALPINA philosophy of hand-craftsmanship
offer a nearly endless spectrum of personalisation.
