THE BMW ALPINA B3 BITURBO
IMPRESSI VE GRACE, POW ER AN D T H R I F T
OF EXCLUSIVE AUTOMOBILES
In ALPINA’s more than 40-year history of manufacturing automobiles, turbo-charged engines have consistently set enduring accents. Launched in 1989, the
BMW ALPINA B10 Bi-Turbo is just one example of the cult status some of these automobiles achieved. In fact, ALPINA’s turbo-charging history began in 1978,
based on the 5 Series and 6 Series of the day. The BMW ALPINA B3 Bi-Turbo models continue this tradition, for the first time on the basis of the BMW 3 Series
Innovative Technology, class leading Fuel Economy and exceptional Performance – Attributes found in all B3 Bi-Turbo Variants
The heart of the B3 Bi-Turbo offers 265 kW (360 hp) at 5,500 - 6,000 revolutions per minute, as well as maximum torque of 500 Nm from 3,800 - 5,000 rpm.
The B3 Bi-Turbo’s engine has a sporty engine’s willingness to rev to 7,000 rpm. Equally as present but usually reserved for diesel engines, there is vigorous
torque from 1,300 rpm onwards. The result: a powerband broader than ever before experienced, guaranteeing both sporty and bullish driving dynamics.
Technically, this is all made possible due to the exceptional BMW base engine with injectors centrally located over the pistons – the state-of-the-art in direct
injection technology. For more than a year, ALPINA engineers researched, developed and tested, both on the engine test bench and on the road. Ever refining
the ALPINA engine map to leverage all the advantages offered by modern direct injection, the potential inherent in the BMW basis was maximised. The use of
extremely durable MAHLE pistons allows for a maximum boost of 1.1 bar with a 9.4:1 compression ratio. The result, peak specific values of 89 kW (121 hp)
per litre and a maximum average pressure of 21 bar.
The allure of the new BMW ALPINA B3 Bi-Turbo is found in its V8 like performance, but with the advantages of a much lighter and noticeably thriftier 3.0-litre
straight-six, a six with an aluminium block and twin-turbo charging. The smooth-running nature inherent in this engine concept is even more prominent when
the engine is charged.
The BMW ALPINA B3 Bi-Turbo embodies pure driving enjoyment – whether cruising along or enjoying all 7,000 revs in each gear. The reason for the
spontaneous responsiveness of the B3 Bi-Turbo is the ZF 6-speed sport automatic transmission with its very short shift sequences, which smoothly processes
the power through the drivetrain without any uncomfortable interruption of forward momentum. The driver may also choose to shift manually at the wheel
using SWITCH-TRONIC, which contributes in no small part to both the awe-inspiring performance numbers and the ability to save fuel in top gear. Frugality
and driving excitement are therefore not contradictory in the B3 Bi-Turbo. Driven by high torque means using sixth gear on the Autobahn is more than
sufficient in almost all situations.
The engine’s kick is extraordinary: 0-100 km/h in 4.8 seconds (Touring: 4.9 s / Cabrio: 5.0 s) and thrust-like acceleration that keeps pulling all the way up to a
top speed of 285 km/h (Touring: 282 km/h / Cabrio: 280 km/h). Indulgence without remorse: in spite of its stellar performance, the BMW ALPINA B3 Bi-Turbo
achieves excellent fuel economy, especially in comparison to its competitors.
One of the B3 Bi-Turbo’s features that literally stands out are the four exhaust tips, with their EMITEC catalytic converters contributing significantly to the
achieving of Euro4 emissions standards.
Typically ALPINA – the finest Materials, superior Ergonomics and high levels of Safety
The intense driving experience and the immediate bonding with the B3 Bi-Turbo are markedly influenced by fine materials and superior ergonomics. The
standard leather interior features comfortably-padded sport seats with excellent lateral support, making long journeys a joy. The ALPINA SWITCH-TRONIC
steering wheel falls perfectly to hand and affords a clear view of the typical ALPINA blue instruments with their red pointers. As demanded by any enthusiastic
driver, the provision of essential information in the form of the analogue oil temperature gauge (from 70° - 170° C) located below the rev counter means the
B3 Bi-Turbo can be pushed to its limits, once the minimum oil temperature of 70° C has been reached. Next to the analogue speedometer, the B3 Bi-Turbo
also provides a digital speed read-out as well as average fuel economy and instantaneous fuel economy figures – thrifty driving also creates driving pleasure.
Immediately noticeable is the B3 Bi-Turbo’s light-footed, extremely agile handling. The secret lies in an ideal 50/50 weight distribution between front and
rear axles in combination with ALPINA’s neutral and supple suspension. Augmenting this agility are light-weight 18” ALPINA CLASSIC wheels shod with
conventional MICHELIN tyres, 245/40 ZR18 front and 265/40 ZR18 rear, with a conscious choice having been made not to use heavy Run-Flat tyres. 19”
wheels offer an even higher level of potential lateral acceleration – in either DYNAMIC or CLASSIC design.
ALPINA’s newest creation reduces aerodynamic lift, especially approaching top speed. The greatest contributing factors are the optimised front and rear
aerodynamics, helping guarantee true driving safety, not just creating a feeling of safety.
Automotive Delicacies – Unique and full of Attention to Detail
In quite exclusive fashion, we’ll complete but a few hundred B3 Bi-Turbos in Buchloe per annum for automotive connoisseurs. As tradition holds, each
automobile will be fitted with an ALPINA plaque identifying its unique production number.
With the advent of the BMW ALPINA Bi-Turbo models, ALPINA serve up automotive delicacies that remains positively anchored in one’s memory, re-inforced
each time one slides behind the wheel. Enjoyment, caring attention to detail and a unique driving environment meld to form a synergy of elegance and
BMW ALPINA B3 BiTurbo ALLRAD SALOON, Touring And Coupé
The B3 Bi-Turbo’s intelligent all-wheel-drive uses BMW’s xDrive system as its technical basis. This dynamic control system distributes the engine’s power
steplessly and variably to the front and rear axles. The heart of this system is the electronically-controlled multi-plate clutch that reacts to changing driving and
road conditions in milliseconds. The required information, such as wheel rpm, steering angle and throttle position, are supplied by the DSC sensors.
Safety and Sportiness on All Fours
The all-wheel-drive system’s functions go almost unnoticed by the driver, this is the pre-condition for a cultivated and comfortable drivetrain. However, the
desired agility and sportiness, is in no way negatively impacted. The opposite is true, as the B3 Bi-Turbo’s self-steering properties are positively influenced
by the instantly-variable shift of power, right up to the limit. The B3 Bi-Turbo’s all-wheel-drive system feels far more agile and dynamic than those of its
competitors. Furthermore, the B3‘s drivetrain suffers no binding or steering that’s too heavy when parking. When manoeuvering and parking, but also near top
speed, the B3 send its power almost completely to the rear wheels.
