Performance Touring, brilliantly styled

The Touring smartly combines the exclusive sophistication of the ALPINA B5 Saloon with pronounced functionality and versatility. Make no mistake, the Touring offers up to 1670 litres of storage space and an ingenious luggage compartment concept, despite its luxury high performance genes.

A finely honed suspension and chassis configuration combined with variable dampers makes for an exemplary ride comfort while simultaneously providing sharp handling and excellent high-speed stability.

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.

THE POWERTRAIN – First Class In Both Performance And Economy

First introduced in the BMW ALPINA B7 Bi-Turbo, the all-aluminium V8 powerplant endows the new B5 Bi-Turbo Touring 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 low revs.

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 B5 Bi-Turbo Touring's class-leading performance in terms of emissions and economy in the super saloon segment: 10.9 l/100km (26.4 Imp. mpg) and 255g/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 B5 Bi-Turbo Touring 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 Touring allows for super quick up-shifts in just milliseconds, in spite of the high torque.

Depending on the load onthe 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 B5 Bi-Turbo Touring strong performance figures: just 4.8 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 B5 Bi-Turbo Touring, 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 Touring is equipped with electronically adjustable 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 Touring transitions effortlessly from cultivated luxury to thorough-bred sportiness. Light steering, ultra-comfortable suspension and an imperceptibly shifting transmission B5 Bi-Turbo Touring 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 Touring 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 B5 Bi-Turbo even more agility. When placed in Sport+ mode by the driver, the B5 Bi-Turbo Touring'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 B5 Bi-Turbo Touring 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 B5 Bi-Turbo's ALPINA family heritage. The ALPINA exhaust's two double-ended-pipes are artfully integrated into the rear valance, a discreet rear diffuser completing the silhouette. The diffuser can be deleted as needed, should the customer desire the optional ability to tow a trailer. In combination with the rear spoiler, the B5 Bi-Turbo Touring'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 Touring'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.

THE BMW ALPINA B5 BITURBO TOURING – Brilliantly Balanced High Performance

The overall harmony and the accomplished manner with which the B5 Bi-Turbo Touring's last fine calibrations were achieved are a common thread, and as always carry that ALPINA flair, our signature. Sovereign performance and opulent torque assure excellent performance, this in conjunction with "best-in-class" fuel economy and CO2 emissions. Neutral turn-in and road-holding, agile handling and a many-faceted, adjustable suspension satisfy the highest demands in terms of comfort and a sporting nature. 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.
