2008 Artega GT

The idea for developing the Artega GT can be considered the "dream order" for a highly motivated team: to develop an extraordinary sports car with entirely unique special accents quasi as calling card of the internationally successful electronics supplier paragon AG. The Artega concept was to establish a totally new brand, and the team's commission was short and to the point: driven by enthusiasm for sporty cars, demonstrate total competence for automotive development. A mission whose realisation called for what turned out to be four major development focus areas:

Design: extraordinary form language

The renowned designer Henrik Fisker succeeded in creating proportions of 3950 x 1880 x 1180 mm (L,W,H) for the first time in this constellation and consequence, namely: broad, flat, and compact. A powerful and elegant front characterised by flowing lines, a low unique windowed greenhouse of a body in highly individual arched form and a classy curve as transition to the beefy rear end all lend the body its striking personal appearance. The uncramped interior surprises despite the vehicle's extremely compact design. Two adults not only have plenty of room, but there's also space for much more than just the most necessary luggage. Even a child's seat can be integrated if desired.

Design features: agility, driving dynamics and safety

The major development parameters for the vehicle body were lightweight design and rigidity. A generously dimensioned aluminium spaceframe in connection with a body made of carbonfibre reinforced compound materials thus ensures a top power-to-weight ratio. For reasons of efficient space utilisation, ideal weight distribution and the best possible traction, the high-grade drive components of the Volkswagen Group are installed as rear engine traverse to the direction of travel. The 3.6-litre V6 is the ideal drive for a vehicle of this class. Along with the highly praised and well-tried direct-shift gearbox, the engine is mounted in a compact module made of highstrength steel tubes. The backs of the comfortable sports seats fold back to make loading easier. Especially effective crash modules as well as a steel side-collision protection as essential features of the passive safety system protect the passengers with front and side airbags in the case of accident. To ensure a maximum of active safety, the Artega GT design integrates state-of-the-art driver assistance systems, such as ASP (Artega Stability Program) such as the electronic stability program ASP (Artega), ABS and the traction control TC. Just as in other super sports cars, four different drive programs can be selected at the Headunit: Normal (ASP with early intervention, TC on), Sport (ASP with later intervention, TC on), Race (ASP off, TC on) and Off (ASP off, TC off).

Fitness for travel: a "sensible" amount of room despite sports car dimensions

In designing the body and interior of the car, great care was taken to consider the needs and comfort of the occupants. The generous amount of space compared to the extremely compact overall dimensions, numerous convenient interior places to put things and two separate luggage compartments (one behind the seats and the other under the front hood) are exceptional for a car this size. Such storage conditions were made possible by the engine's transverse installation in the rear. Although the Artega GT provides phenomenal handling performance and drive capabilities, the chassis fine-tuning ensures that comfort in no way comes too short. Even long trips will be savoured in happy memory by the driver and passenger - and even if the top cruising range provided by the optional 80-litre tank is fully used.

Operation: paragon makes driving easier, more pleasant, and safer

The competence of the electronic specialists at paragon AG has provided comprehensive innovative systems for operation and driver information. One of the primary concerns of the Artega idea is to prove their benefit in the Artega GT.With innovative sensor buttons and the unique dual-pointer dashboard for road speed and engine speed, paragon offers a novel ambience as a significant, distinctive attribute of the Artega GT.These features are emphasized by a plaque with the inscription "Cockpit systems from paragon" in the interior of the vehicle.

2007 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.

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 surprises even those in the know: 0-100 km/h in 4,9 seconds and thrust-like acceleration that keeps pulling all the way up to a top speed of 285 km/h. Indulgence without remorse: in spite of its stellar performance, the new BMW ALPINA B3 Bi-Turbo achieves excellent fuel economy in relation to its competitors. One of the B3 Bi-Turbo's features that literally stands out are the four exhaust tips, with their catalytic converters contributing significantly to the achieving of low Euro4 emissions standards.

The intense driving experience and an 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 located below the rev counter means the B3 Bi-Turbo can be pushed to its limits, once the minimum oil temperature of 50° 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 balance between front and rear axles in combination with a ALPINA's neutral and supple suspension. Augmenting this agility are light-weight 18" ALPINA CLASSIC wheels shod with conventional MICHELIN tyres, 225/40 ZR18 front and 255/35 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 contributors are the optimised front and rear aerodynamics, helping guarantee true driving safety, not just creating a feeling of safety.

2008 Alpina BMW D3 Bi-Turbo Coupe

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.

The D3 Diesel Technology

The D3 Bi-Turbo's basis is derived from the BMW 2.0-litre, four-cylinder, turbo-charged diesel engine with a block entirely of aluminium. The highpressure, 2000 bar Bosch-Common Rail system ensures high efficiency by means of utilising Piezo injectors. Two differently-sized exhaust-driven turbo-chargers breathe on the D3 Bi-Turbo. The smaller of the two chargers begins to operate right from tick-over and helps the four-cylinder yield an impressive 400 Nm (295 lbs-ft) of torque at a mere 1,500 rpm. Peak torque of 450 Nm ( 332 lbs-ft) is reached at 2,000 rpm.

From about 3,000 rpm onward, the second, larger turbo-charger, is then fully on line and drives the engine to its peak performance of 214 horsepower (211 bhp, 157 kW). Thanks to extensive development work, optimal turbo-charger mapping and the fuel injection system, the new D3 Bi-Turbo allows revs up to 5,200 rpm, where most diesel aggregates today stop at 4,500 rpm. The base engine's configuration, as developed by BMW engineers in Steyr, provides the potential to make the Alpina BMW D3 Bi-Turbo's immensely high specific output of 107 horsepower per litre possible.

The Efficient Transfer of Power

The standard six-speed manual gearbox allows the driver to not only test the 5,200 rpm redline, but also to enjoy the driving experience in a way previously unknown to a diesel. Coupled with carefully-calibrated gear spacing, the broad useable torque curve makes possible an unusually lightfooted form of forward progress, especially on winding country lanes.

At the request of many customers, one can now enjoy the D3 Bi-Turbo with the optional SWITCH-TRONIC. This classic combination of plenty of torque and an automatic transmission, offers the driver a high degree of flexibility.

Using the normal "D" Drive mode, the SWITCH-TRONIC shifts into the next gear most comfortably and almost unnoticed by the driver. "D" mode uses the engine's impressive torque, allowing a driving style that's very economical. In "S" mode, the up-shifts are later in the rev range, and quicker. This provides for the kind of driving characteristics that to date were only to be found in strong petrol engines.

The D3 Bi-Turbo only really becomes the perfect "Sport Diesel" though, when the driver shifts manually using the shift buttons on the back of the steering wheel. Lightning-quick shifts are the order of the day - even the best drivers can't shift any quicker than themselves. This reveals itself in impressive performance numbers for both transmissions The manual D3 Coupé reaches 100 km/h [62 mph] in 6.9 seconds (automatic 7.0 sec), with a top speed of 244 km/h [152 mph].

Especially in light of the current CO2 discourse, the Alpina BMW D3 Bi-Turbo Coupe's fuel economy figures for the EU combined cycle of 5,4 (5,6) l/100 km [52.3 Imp. gal (50.4)] and resultant CO2 emissions of only 143 (148) g/km, reveal Alpina's efforts regarding highest fuel efficiency. In addition, all measures to reduce consumption and CO2 emissions used in the base BMW model were carried over into the D3, such as the automatic Start-Stop function on models with manual transmissions. High-mileage drivers and business users appreciate the resulting range: depending on driving style, up to 1,000 km (600 miles) are the norm.

In Conclusion
Alpina typical interior and exterior design cues demonstrate the Alpin BMW D3 Bi-Turbo Coupe's individuality and elegance. Attractive light-alloy wheels, an instrument cluster with blue dials, and a leather sports steering wheel with Alpina emblem and multi-functionality (automatic tranmission) are standard on the D3 Bi-Turbo. The front spoiler minimises lift and underscores the Coupé's aesthetic lines, which can be augmented further with an optional rear spoiler.
Initially offered as a Coupé, the D3 will also be available as a Saloon and Touring in Autumn 2008. With the advent of the new-generation D3, Alpina furthers the previous model's success.

2010 Alpina BMW B7 Bi-Turbo

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.

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 intercooler tracts. All three intercoolers, the low-temperature intercooler integrated into the radiator package, as well as the two engine-near intercoolers are enlarged by approximately 35%, ensuring very high thermo-dynamic efficiency.

High-performance pistons are at work in the engine, carefully developed to withstand the thermo-dynamic forces created by 9.2:1 compression 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.

Further technical subtleties of this high-tech, EU5-emissions rated powerplant include petrol-direct-injection and Double-VANOS. These contribute in no small measure to the Alpina BMW B7 Bi-Turbo's "Best-in-Class" fuel economy 12.1 l/100km [23.4 Imp. MPG] and a CO2 emissions rating of 282g/km (mixed fuel economy according to ECE norm).

The Alpina BMW B7 Bi-Turbo delivers proof, both in form of its characteristics and its technical data, that high levels of performance and favourable fuel economy are not necessarily a contradiction in terms. Ending in two polished double-tailpipes, the stainless-steel Alpina exhaust system offers up that deep and sonorous yet not intrusive V8 sound that one has come to expect from Alpina.

DRIVETRAIN COMFORT - UNIQUELY SUPERIOR
The Alpina BMW B7 Bi-Turbo is the result of the consistent execution of the Alpina philosophy, in itself the reason why the sharp yet gracious Alpina BMW B7 Bi-Turbo shines so brilliantly in everyday use.
One look at the torque and power diagram is enough to highlight that the Alpina BMW B7 Bi-Turbo will accelerate fiercely yet 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 Alpina BMW 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 Alpina BMW 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. Although one rarely finds oneself in need of such haste, the ventilated and generously-proportioned (374 mm dia. front, 370 mm dia rear) high-performance braking system guarantees deceleration values on par with pure-bred sports cars.

THE SUSPENSION - HARMONIOUS, ACCOMPLISHED, IMPRESSIVELY VERSATILE
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 technologically feasible. 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 sportsoriented 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 and skilfully, subtly adjusting them to the demanding requirements of our customers. As part of the Alpina BMW 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. These are intentionally calibrated to provide noticeably different set-ups, influencing the characteristic of the dampers, the active roll stabilisation as well as the parameters of the power steering assist, throttle response algorithms and load-reversal damping. The Alpina BMW 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.

Seasoned drivers are not kept from pushing the Alpina BMW B7 Bi-Turbo hard at the limit: the Sport plus mode automatically shifts the traction control systems into Dynamic Traction Control (DTC), an extension of DSC. This allows noticeably more slip at the driven wheels and delayed intervention by the traction control system.

DESIGN & INTERIOR - EVOLUTIONARY STYLING, DOWN TO THE LAST DETAIL
At once dynamic, graceful and potent - the silhouette of the Alpina BMW 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 Alpina BMW B7 Bi-Turbo's potency.
When climbing into the Alpina BMW B7 Bi-Turbo, one immediately takes note of the Alpina door sill trims which are finely illuminated in blue. The SWITCH-TRONIC steering wheel, 385mm in diameter, 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.

2010 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.

Comfort / Normal: set-up for maximum safety and comfort, handling is decidedly forgiving and sudden changes in direction will be met by mild understeer.

Sport: facilitates a more assertive driving style with the active role stabilisers programmed to neutral handling with reduced understeer.

Sport+: skilled drivers will particularly enjoy that in this program the torque bias is shifted predominantly to the rear wheels, enabling levels of lateral acceleration and a super-sporty driving style unheard of luxury saloons. In addition, the DSC automatically goes into DTC mode, reducing the intervention of the electronic stability program and allowing more slip at any of the driven wheels.

Regardless of whether Comfort, Normal or Sport is selected, the system recognises lateral acceleration above 0.5 m/s2 as resolute and sport-oriented driving and increases the torque shifted to the rear wheels, without reducing stability.

The instantaneous and fully variable torque distribution remains active regardless of the selected program and constantly delivers the highest levels of traction and active safety in every situation, such as when driving on very mixed road surfaces.

 

Despite the Alpina BMW B7 Bi-Turbo Allrad's high level of torque, intervention of the DSC stability control system by applying the brakes or by reducing engine output, is only seldom necessary because the intelligent torque distribution is extremely effective at neutralising any indication of under- or oversteer at the onset.

 

The Alpina BMW B7 Bi-Turbo Allrad tracks in and out of all corners as if on rails - levels of steering lock, lateral acceleration, yaw rates and speed are constantly dictating how much torque needs to be supplied to which axle in order to ensure maximum forward progress.

2011 Alpina BMW B5 Bi-Turbo

THE POWERTRAIN - First Class In Both Performance And Economy

First introduced in the Alpina BMW B7 Bi-Turbo, the all-aluminium V8 powerplant endows the new B5 Bi-Turbo with sensational pace. It achieves 507 horsepower (373 kW) at a moderate 5,500rpm, with maximum torque of 700Nm from 3,000 to 4,750rpm. The "Bi-Turbo" appellation refers to the two turbochargers comfortably nestled inside the V shaped 8 cylinder block. They work in parallel, each feeding one of the two cylinder banks. Specially developed for Alpina in partnership with Honeywell-Garrett, the bespoke exhaust turbines are generously dimensioned. Compared to its super-charged predecessor, this engine configuration delivers more torque over a broader rev range and improves throttle response at lowrevs.

To fully leverage the potential of the engine, Alpina have optimised the indirect inter-cooling system (air-to-water / water-to-air) with short intake tracts and increased inter-cooler flow. The high-performance cooling package gains its thermo-dynamic efficiency through the use of a large-volume low-temperature inter-cooler, as well as two water-to-air inter-coolers placed close to the engine. The pistons are a high-performance variant developed together with Mahle to deal with the extreme 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 Alpina BMW B5 Bi-Turbo's class-leading performance in terms of emissions and economy in the super saloon segment: 10.8 l/100km (26.2 Imp. mpg) and 252g/km CO2 (Combined as per the ECE Norm).

TRANSMISSION - The Eight-Speed All-Rounder

Adapted and tested in cooperation 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 sportiness.

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. The 700Nm of torque means the Alpina BMW B5 Bi-Turbo excels at gliding along at low speeds in a high gear with minimum revs, benefiting both consumption and comfort.

In Sport mode a completely different character emerges: the transmission is crisp and unmistakably immediate. The innovative single-cylinder step-down (EZA), specially developed by Alpina for the B5 Bi-Turbo allows for super quick up-shifts in just milliseconds, in spite of the high torque. 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 advantage versus the typical timing retardation are noticeably quicker shifts, and improved thermo-dynamic efficiency due to reduced exhaust temperatures as well as lower fuel consumption. The single-cylinder step-down (EZA) is accompanied by a tone nothing short of spectacular, as each shift harbours a deeply sonorous back-pressure burble.
The Manual mode gives the driver full control over every shift. The SWITCH-TRONIC buttons are ergonomically and aesthetically positioned on the back side of the steering wheel, and can be used by the driver in whatever manner he or she wishes, based on traffic and the roadway at hand. The system also allows for multi-simultaneous down-shifts in fractions of a second, hereby the transmission will skip several gears depending on accelerator loads and revs. In this manner the 8-speed sport automatic transmission with Alpina SWITCH-TRONIC reveals itself to be multi-faceted and able to provide the proper shift characteristic for any and all situations.
The intelligent coupling of state-of-the-art engine and transmission technologies give the Alpina BMW B5 Bi-Turbo strong performance figures: just 4.7 seconds to 62mph (100km/h) are needed, on the way up to a top speed of 191mph (307km/h).

Even if the driver is seldom in such a rush: massive braking capability in the form of ventilated high-performance brakes (front: 374mm/14.7in; rear 370mm/14.6in) ensures braking on par with pure-bred sports cars.

SUSPENSION - Excitingly Sporty, Relaxingly Comfortable
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 yet very progressive springs and special suspension arms, which in combination results in more camber on the front track.

Together with 20" wheels and tyres, Alpina have achieved a very balanced and direct chassis set-up, discarding a pure sport-orientated approach for an agile suspension with precise turn-in. The new light-weight 20" Alpina CLASSIC are shod with the most advanced high performance tyre technology available today. Making their debut on the Alpina BMW B5 Bi-Turbo, the new MICHELIN PILOT SUPER SPORT tyres, which measure 255/35ZR20 at the front and 285/30ZR20 at the rear, provide highest levels of high-speed stability. In addition to improved all-round capabilities, these non run-flat tyres provide greater traction on wet roads, offer improved hydro-planing behaviour and excellent rolling comfort.

To fulfil the highest demands in terms of comfort, everyday usability and razor-sharp handling when called for, the B5 Bi-Turbo is equipped with electronicallyadjustable suspension (Variable Damper Control). Using the control switch mounted to the left of the shift lever, the driver can select between Normal, Comfort, Sport and Sport+. This system has been artfully calibrated by Alpina, and is tied into other system parameters controlling steering assistance, torque cushioning and DSC. The B5 Bi-Turbo transitions effortlessly from cultivated luxury to thorough-bred sportiness. Light steering, ultra-comfortable suspension and an imperceptibly shifting transmission Alpina BMW B5 Bi-Turbo the 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.
When the 8-speed sport automatic's manual mode is combined with the selection of the Sport or Sport+ modes, the driver benefits from a new feature: no mandatory up-shifts. When truly pressing on through twisty sections of road or around hairpins, skilled drivers can remain in their selected gear and not be interrupted by an up-shift.
The optionally available Dynamic Drive reduces body roll in corners, awarding the Alpina BMW B5 Bi-Turbo even more agility.

When placed in Sport+ mode by the driver, the B5 Bi-Turbo's dynamic control systems offer a heightened form of DSC called Dynamic Traction Control (DTC), which allows noticeably more slip at the rear wheels and delays the point at which the traction control systems take over.

DESIGN & INTERIOR - Classic Craftsmanship Meets Modern Technology
The new Alpina B5 Bi-Turbo presents typical Alpina virtues and design cues in a new and convincing fashion, with a refreshing and dynamic appearance.

The self-assured and powerful front commands attention with its decidedly sport-orientated lines and striking air. The rear is especially harmonious, clearly communicating the Alpina BMW B5 Bi-Turbo's family heritage.

2011 Alpina BMW B5 Bi-Turbo 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 ALPINA 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 ALPINA 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 ALPINA 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 ALPINA 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 ALPINA B5 Bi-Turbo transitions effortlessly from cultivated luxury to thorough-bred sportiness. Light steering, ultra-comfortable suspension and an imperceptibly shifting transmission make the ALPINA 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 ALPINA 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 ALPINA 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 ALPINA 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 ALPINA 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.
