BMW ALPINA B6 Bi-Turbo with Akrapovi

POWERTRAIN

First class performance and economy

The all-aluminium V8 power plant produces 507hp (373kW) at a moderate 5500rpm, with a maximum torque of 700Nm between 3000rpm - 4750rpm. Two turbo-chargers configured in parallel, each feeding one of the two cylinder banks, with 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 B6 Bi-Turbo’s class-leading consumption and emission figures: 10.9l/100km (25.9mpg) and 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 benchmarks. With ALPINA’s philosophy the guiding credo, 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.

In the Automatic Shift Mode (D) 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 B6 Bi-Turbo excels at cruising along at speed in a high gear at minimum rpm, benefiting both consumption and comfort.

Using the Sport Shift Mode (S) a completely different character emerges: the transmission is crisp and unmistakably immediate. The innovative single-cylinder fadeout (known as 'Einzelzylinderausblendung‘ in German) 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 Shift Mode (M), 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 Performance Control button and the selection of the M Shift Mode will deactivate the automatic up-shift function. 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

B6 Bi-Turbo stunning performance figures: 0-100km/h in 4.8s, and a top speed of 311km/h.

CHASSIS & SUSPENSION

Dynamic Comfort

High-performance convertibles place special demands on their chassis - requiring distinct levels of comfort for easy cruising, safe and neutral handling at top speed, and light-footed agility for the moments in between. In order to do justice to this broad spectrum of requirements, the new B6 Bi-Turbo Convertible features the latest electronic suspension technologies and comes with Drive Performance Control (electronically adjustable dampers) and Dynamic Drive (active roll stabilisation) as standard.

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+, Comfort, Sport and Sport+ modes, the B6 Bi-Turbo transitions effortlessly from cultivated luxury convertible to thorough-bred sports car.

Specific springs, increased front wheel camber and a subtle adjustment of the toe-in in conjunction with a 20” wheel-tyre combination all serve to produce a very agile chassis set-up. The lightweight 20” ALPINA CLASSIC wheels, with MICHELIN PILOT SUPER SPORT tyres in the dimensions 255/35 ZR20 front and 285/30 ZR20 rear, contribute significantly to the direct handling and precise steering. Conventional tyres are used to promote ride comfort.

DESIGN

DESIGN EXTERIOR – Exciting Details, Functional Aerodynamics

The BMW 6 Series is marked by an elegant and dynamic design as well as excellent aerodynamic properties. ALPINA gives the new B6 Bi-Turbo a unique, powerful appearance which elegantly underlines the sporty character of this beautiful convertible.

The exterior components that influence the aerodynamic properties of the B6 Bi-Turbo are not just there for aesthetic reasons – their design is subject primarily to functional premises and plays a considerable role in achieving both the top speed and in reducing fuel consumption. Take for example the front spoiler with the integrated carbon fibre front splitter. It causes more air to flow over and around the vehicle, simultaneously reducing the air masses which flow underneath by more than 10%. This leads to a noticeable stabilisation of the front-end at high speeds and plays a role in reducing any tendencies to understeer. The front spoiler, in conjunction with the rear spoiler, ensures that the B6 Bi-Turbo is very well ‘tethered’ overall. Uplift on the front axle is reduced by 14% and tends towards a value of zero on the rear axle from a speed of 150 km/h onwards.

In addition to an improvement in the CX values, these components also ensure the effective flow of air to various cooler groups, such as the inter-coolers and engine cooling system. One special detail: the high-performance brakes, with a diameter of 374mm front and 345mm rear, are additionally supplied with cooling air by a specially constructed NACA air intake on the front underbody.

The double tailpipes, with a slightly elliptical shape in typical ALPINA style, are designed in titanium and carry small logos that make discreet reference to the origins of the ALPINA exhaust system made by Akrapovic. The rear valence, which attractively and elegantly frames the outlet of the tailpipes, additionally integrates the features of a diffuser.

DESIGN INTERIOR – Master Craftsmanship, Exclusive Personalisation

Blue ALPINA instruments with high resolution information display with black panel LCD technology. A sport steering wheel, hand-stitched in LAVALINA leather. Blue illuminated entry sills with logo. Or the classic ALPINA exotic wood equipment in myrtle – an exclusive burl wood of the laurel family, which grows only on the Pacific coast of the USA. These are just some of the elegant features of the interior that point to the exclusive origins of the B6 Bi-Turbo Cabrio.

Naturally, no limits are set on the personal predilections of customers. From the paintwork to the interior trims to the colour of the upholstery – everything offered by the extensive BMW and ALPINA equipment range is available. Seldom does a BMW ALPINA leave Buchloe without making use of the virtually limitless personalisation options offered by the ALPINA Manufaktur. Our philosophy dictates that the customer can design his or her own individual interior – made by skilled craftsmen in our leather workshop.
