(from Alpina Press
Release) THE NEW BMW ALPINA B3 S BITURBO
turbo-charged automobiles have always played a central role in
ALPINA’s more than 45-year history as a manufacturer – the 1989 BMW
ALPINA B10 Bi-Turbo is an excellent example, having achieved true
In 2008 the BMW ALPINA
B3 Bi-Turbo rekindled this tradition, combining Bi-Turbo charging
with the compact dimensions of the BMW 3 Series.
The new BMW ALPINA B3 S
Bi-Turbo couples improved performance and torque with reduced fuel
consumption and CO2 emissions - it is the logical result of
continuous engineering development at the highest level. The B3 S
Bi-Turbo builds upon the highly-praised traits of its predecessor
and presents itself as one of the most harmonious and multi-faceted
sports cars in its segment. Whether Saloon, Coupé, Touring or
Convertible, whether rear-wheel drive or all-wheel drive – the B3 S
Bi-Turbo marries explosive performance with a high level of comfort
and everyday usability, addressing the needs of an unusually broad
target group of automotive connoisseurs!
Clever and Athletic
Agile, powerful athletes
graced with endurance. The B3 S Bi-Turbo’s exceptional powerplant
yields 294kW (400hp) at 6000rpm with a maximum torque of 540Nm
(397lbs-ft) at 4500rpm. The sporting engine revs cleanly up to
7000rpm, yet offers massive thrust across a wide powerband – 400Nm
(294lbs-ft) of torque is already available from just 1300rpm, all
the way to 6000 rpm. Rarely has sporty, dynamic and economic driving
been so enjoyable.
Prerequisite for this
level of performance is the outstanding BMW 3.0-litre straight-six
cylinder petrol engine with 2nd-generation direct injection
(centrally located injectors) combined with Bi-turbo charging.
Permanent development and years of testing allow ALPINA engineers to
extract high levels of output from this engine by utilising all the
possibilities modern direct injection offers.
The air intake and air
filter system have been optimised in terms of pressure loss, with
the exhaust system optimised in terms of back pressure – both steps
effectively making air-intake and exhaust-gas flows more efficient.
In combination with high-strength MAHLE pistons, a maximum boost of
1.2 bar with a compression ratio of 9.4:1 can be achieved. The
result is a class-leading specific output of 98kW (133hp) per litre.
A high-performance cooling system with an additional cooling
radiator helps maintain optimum operating temperatures, even in
extreme driving situations.
Offers More, Demands Less
Exceptional efficiency –
more performance, better economy. Despite superior performance, the
new BMW ALPINA B3 S Bi-Turbo retains its class leading fuel economy
figures: just 9.7 l/100km (29.1 mpg) and 224-225 g/km CO2 in the
combined EU test cycle and achieving EU5 Emission Standard (figures
for all-wheel drive please see technical data).
The modern direct
injection system enables especially efficient combustion at low
throttle loads while the air flow and mapping optimisations improve
realworld driving fuel economy by over 5%. The new B3 S Bi-Turbo
shows once more, that innovative technology and dedicated
engineering allow modern highperformance automobiles to achieve
remarkable fuel economy.
The B3 S Bi-Turbo’s
charm lies in its V8-like performance drawn from a lighter, much
more frugal 3.0-litre straight-six with aluminium block and Bi-Turbo
charging. This performance can be called up effortlessly and almost
anywhere in the rev range. The 0-62mph sprint is a breeze and is
over in just 4.7 seconds.
Both the Saloon and
Coupé can achieve a top speed of 300km/h (186mph).
The ALPINA SWITCH-TRONIC offers up shifting characteristics for
every taste and situation. While the automatic mode shifts gently
and comfortably, the transmission reveals its true sporting
qualities in manual mode: using the shift buttons on the back of the
steering wheel, the driver can up-shift in just a few hundred
milliseconds with no perceptible loss in power. Sporty drivers
especially appreciate the blip of the throttle which synchronises
revs on manual downshifts, meaning nothing unsettles the balance of
the car when using the whole rev range. Efficiency and driving
pleasure are beautifully united in the B3 S Bi-Turbo. Due to the
massive torque, use of top gear on the autobahn is sufficient for
almost all driving situations, and also exceedingly thrifty.
Evolution Meets Heritage
The BMW ALPINA Coupés
und Convertibles based on the BMW 3 Series have always captivated
the eye through their elegant, fine lines and tasteful presence. The
dynamic appearance of the B3 S Bi-Turbo is in part defined by the
modern and functional front spoiler. Engineered using the newest
developments in aerodynamic design, the spoiler reduces lift at the
front and enables optimal air flow to the high performance cooling
system. The Coupé and Convertible carry a new rear valance which
communicates a tasteful sporting charm through its integrated rear
diffusor and two distinctive double-ended exhaust pipes, a little
like the stern of powerful luxury yachts.
A fresh, evolutionary
design with a clear heritage. The new ALPINA CLASSIC 19“ light-alloy
wheels underline the finely-proportioned forms of the new B3 S
Bi-Turbo models. Reminiscent of a turbine and with a
three-dimensional sweep, each of the 20 spokes leads from the hub
right to the edge of the rim, making for a very fluid and dynamic
appearance even when motionless. Unique: the new design retains the
hidden air valve mounted in the wheel centre, which is covered by a
lockable hub cover, leaving the wheels flawless in their form and
A warm sense of
well-being thanks to fine materials, brilliant ergonomics and
The comprehensive level of standard equipment convinces: leather
sport seats offer excellent lateral support and comfort on long
journeys, the ALPINA SWITCHTRONIC leather sports steering is
luxurious to the touch, the blue ALPINA instrument display provides
additional information such as engine oil temperature and a digital
Also as standard come
high levels of safety and light-footed, agile handling. Firm rear
sub-frame bushings increase the ALPINA suspension’s driving
precision during quick changes in direction. The secret is the ideal
50/50 front/rear weight balance coupled with a supple suspension
that’s neutral, even at the limit. The light-weight ALPINA CLASSIC
wheel and MICHELIN tyre combination reduce unsprung mass and
conventional non-run-flat tyres support a subtle ride. Besides the
standard wheel/tyre set-up with 245/40 ZR18 front and 265/40 ZR18
rear, a 19” wheel/tyre package is available as an option in either
DYNAMIC or the new CLASSIC design.
