Alpina BMW B5
ALPINA presented the BMW ALPINA B5 at the Geneva Salon in march 2005, an automobile with 500 horsepower, maximum torque of 700 Newton metres and a top speed of 314km/h - the fastest production saloon in the world. Yet power isn't the sole defining characteristic of even this BMW ALPINA, an automobile which enriches Buchloe's gourmet offering in both Touring and Saloon form
In the end, the key isn't absolute horsepower, but the manner in which this performance unfolds. In this point, the youngest member of the ALPINA family takes a position at the head of the class - just as its predecessors in ALPINA history. The legendary B10 Bi-Turbo, for example, is a car that enjoys cult status today
In principle, the B5 uses the same powerplant found in the familiar BMW ALPINA B7, with its eight cylinders and 4.4 litre displacement. The engine's forced induction differs from conventional solutions: it is neither turbo, nor of the type of super-chargers that drain a great deal of power from an engine, especially at higher rpm
A radial or "Nautilus-type" compressor delivers the ALPINA V8's boost pressure: one might see it as a combination of super-charger and turbo-charger. It isn't propelled by exhaust gases, as a turbo would be, but rather belt-driven from the crankshaft. The inner workings of the radial compressor compare to the intake side of a turbo: a small turbine generates up to 0.8 atmospheres of boost to the cylinders. Before reaching the engine, the air passes through a generously-dimensioned inter-cooler, capable of sinking intake air temperature up to 70°C

Alpina BMW B7
The BMW 760i - with its 12 cylinders - is unquestionably one of the finest and most comfortable saloons in the luxury segment
There is, however, a small circle of enthusiasts, people who enjoy getting behind the wheel themselves, who yearn for the sportiness provided in a smaller car, but don't want to miss out on an automobile in this class. To achieve optimum agility and handling, ALPINA made a point of basing the B7 on the BMW 7 Series with V8 engine. The V8 offers the best jumping-off point in terms of dynamism, with an ideal 50/50 weight balance, also weighing around 150 kg less than the comparable V12 model
The B7 designation carries with it a long tradition, and has stood for charged engines at ALPINA since the late 1970s. The heart of the B7 is a 4.4 litre V8 engine that is charged through the use of a radial (Nautilus-type) compressor. The combination of Valvetronic and charging represents a premiere. Through the use of Valvetronic's complete functionality, the charge is controlled by varying the valve opening depth and the boost pressure. This frees up the engine breathing and provides better fuel economy at partial engine loads. The radial compressor is driven by a dedicated poly-V-belt, separate from the serpentine belts running the other aggregates. At low rpm, a clutch de-couples the compressor from its drive-belt. The compressed air charge reaches the engine via an air-to-air intercooler. The EMITEC metallic catalytic converters are mounted quite close to the engine. In combination with secondary air induction, the EU4 standard is achieved
Alpina BMW D3
"It has phenomenal pull," was the first impression that Andreas Bovensiepen had of the BMW 320d race-diesel that he raced along with Hans Stuck, Marc Duez and Christian Menzel. Together they took the overall win in none other than the 1998 24 Hours of Nurburgring, the track whose North Loop was and is referred to as the "Green Hell". This remains the biggest racing victory for a diesel-fired vehicle to date, with thanks going to an intelligent package made up of high torque, high fuel economy and finely-honed aerodynamics
An automobile from ALPINA - and cognoscenti know it - is always something special. Packaging is the magic word - to present a car that the informed, sporty and quite emotional ALPINA clientele will appreciate
At the heart of the matter is the 2.0litre diesel, endowed with so much potential by the BMW engineers in Steyr that it achieves just over 100 horsepower per litre in the BMW ALPINA D3. This would be a great result for a high-performance petrol engine, and it's a sensation coming from a diesel. Garrett, of turbo-charger fame, are able to deliver a new charger that simultaneously achieves high levels of air mass through-put with outstanding responsiveness. ALPINA engineers performed intensive development work on the injection system, burn pattern, inter-cooling and exhaust gas emissions (particle filter). The result: 200hp (147kW) at 4,000rpm
What makes this automobile special? First off - it works brilliantly in times of out-of-hand fuel prices. Torque: at 410Nm/302lbs-ft much like a V8 engine. Performance: 0-100kph in 7.4 seconds, with a top speed of 238kph, much like a six-cylinder. Fuel economy: at 6-7 litres per 100km, more like a small commuter car. A truly dynamic automobile that doesn't first create false hopes by shooting away from rest at low revs, only to peter out at higher revs. Instead, the 2.0litre loves to rev, in the hopes that its owner will co-operate fully and happily with both it and the buttery-smooth-shifting 6-speed ZF manual gearbox
Alpina BMW B3 Bi-Turbo
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 (E12 & E28 and E24). The new BMW ALPINA B3 Bi-Turbo continues this tradition for the first time on the basis of the BMW 3 Series with its world premiere at the 2007 Geneva Salon d'Automobile.
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 1,500 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 foundation 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.
Alpina BMW D3 Bi-Turbo Coupe
The new Diesel Bi-Turbo continues the Alpina BMW D3 success story begun in 2006 by the popular 200 HP (147 kW) Alpina sport-diesel model, with over 850 units sold since its inception. It is a most passable answer to the low emissions and consumption discussions of current times, and dovetails perfectly with of out-of-hand fuel prices.
The designation "D" unmistakably indicates the diesel powerplants in the Alpina family. "D" especially stands for dynamism. The new D3 Bi-Turbo, celebrating its world debut at the 2008 GENEVA Salon d'Automobile - with 214 HP/211 bhp (157 kW) @ 4,100 rpm - is an exceptionally powerful and unusually high-revving diesel. Lastly, the "D" on the Alpina BMW D3 Bi-Turbo stands for the German "Drehmoment" or torque, which the D3 has in spades. At 450 Nm (332 lbs-ft) of torque from 2,000 to 2,500 rpm, the 2.0-litre, four-cylinder D3 is operating in V8 engine territory, or amongst large-displacement six-cylinder diesel engines. With the purchase of a D3 Bi-Turbo, an Alpina customer owns an engine transmission combination that is a rare and fine delicacy when measured against its diesel competitors.
The elegant manner in which the power is delivered can be further augmented with the optional SWITCH-TRONIC automatic transmission. Developed by ZF and Alpina in partnership, this sport-automatic is operated via three driving modes: D, S and M. Depending on the driver's mood, he or she may let the transmission shift automatically, or shift manually using buttons on the back of the steering wheel. This affords the broadest spectrum of driving fascination.
Alpina BMW B7 Bi-Turbo
With the new Alpina BMW 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 Alpina BMW 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 Alpina BMW 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 Alpina BMW B7 Bi-Turbo and impart it a distinctive appearance and powerful stance.
POWERTRAIN - FIRST-CLASS IN BOTH PERFORMANCE AND ECONOMY
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 3000-4750 rpm. Two especially for Alpina powerplant constructed turbochargers, one located above each of the V8's two cylinder banks, are responsible for the forced induction. The turbochargers operate in parallel, with generously-dimensioned turbine vanes measuring 44mm in diameter.
Alpina BMW B7 Bi-Turbo Allrad
With the Alpina BMW B7 Bi-Turbo Allrad, for the first time, Alpina combines its powerful, torque-laden flagship with an optional all-wheel-drive system for even more traction and active safety in every and any driving situation.
The Alpina BMW B7 Bi-Turbo Allrad with all-wheel-drive exploits the technical potential of BMW's xDrive System and its intelligent and dynamic distribution of drive power. It continuously and fully variable distributes torque between the front and rear axle within milliseconds.
Alpina's unique mapping of the torque distribution markedly enhances driving dynamics and agility, especially when cornering, enabling unexpected levels of sporty handling. In addition to offering maximum available traction under acceleration, the system provides exceptional levels of active safety by constantly monitoring the driving situation and distributing torque accordingly.
The all-wheel-drive system is linked to the Alpina BMW B7 Bi-Turbo's many electronic control systems, meaning it can offer an unusually broad spectrum of dynamic driving experiences, just like our demanding customers expect. Unique: in combination with the electronic suspension, consisting of Variable Damper Control and Dynamic Drive (active roll stabilisation), the driver can influence the dynamic torque distribution of the all-wheel-drive system using the Drive Dynamic Control buttons to select between the programs.
