For Alpina, a expertise pushed company, standstill is a overseas word. Since the introduction of the B7 Bi-Turbo, the engineers from Buchloe, Germany, have been repeatedly working on the main points of the turbo charging and intercooler system.
Consequently, the all-aluminium V8 energy plant now produces 540hp (397kW) at a average 5500rpm, with a maximum torque of 700Nm from 3000rpm. Two turbo-chargers configured in parallel, every feeding one of many two cylinder banks, with specially developed giant diameter exhaust-generators allow this engine configuration to offer each exceptional power output and an abundance of torque over an particularly broad rpm range whereas maintaining wonderful throttle response at low rpm.
The comprehensive excessive-performance cooling system includes an oblique inter-cooling system (air-to-water/water-to-air) with brief consumption tracts and elevated inter-cooler flow. The programs glorious thermodynamic efficiency is assured by a big-volume low-temperature inter-cooler radiator, two water-to-air intercoolers placed close to the engine and additional separate motor oil and water coolers.
High-performance MAHLE pistons are designed particularly to take care of temperatures and pressures associated with as much as 1.zero bar charging and the engine's 9.2:1 nominal compression ratio. Altogether this results in an impressive specific output of 122.7hp (90kW) per litre and a imply total compression of 20.1 bar. Direct injection and Double-VANOS contribute to the B6 Bi-Turbo's class-leading consumption and emission figures: 10.5 (10.6) l/100km and 244 (247) g/km CO2, Mixed cycle, measured in response to ECE Norm (information for Convertible in bracketsAdapted and examined in co-operation with ZF, the superior SWITCH-TRONIC 8-pace Sport Automated Transmission sets benchmarks. With Alpina's philosophy the guiding credo, engineers have spent thousands of improvement and test hours making certain that no different performance automated transmission comes close to providing this level of both consolation and performance.
The blend of eight speeds and loads of torque makes for unparalleled snug gear changes with no noticeable interruption to the supply of power - solely 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 excessive gear at minimal rpm, benefiting each consumption and comfort.
Using the Sport (S) Shift Mode a very completely different character emerges: the transmission is crisp and unmistakably immediate. The revolutionary single-cylinder fadeout (referred to as 'Einzelzylinderausblendung' in German) allows super quick up-shifts which take simply milliseconds. Depending on the load on the transmission, the injection of gas into a given cylinder is interrupted for a fraction of a second, creating the required discount in torque that the automatic transmission needs for the up-shift. The benefits versus the everyday method of timing retardation are noticeably faster shifts, improved thermo-dynamic efficiency because of diminished exhaust temperatures and lower gasoline consumption. Each up-shift is accompanied by a deep again-pressure burble.
The SWITCH-TRONIC buttons, to be used in the Manual (M) Shift Mode, are ergonomically and unobstrusively positioned on the back of the steering wheel, and permit the motive force to take complete control of the transmission. The system permits for multi-simultaneous down-shifts in milliseconds, hereby the transmission will skip a number of gears depending on engine masses and rpm. On this method the 8-speed Sport Automated Transmission with Alpina SWITCH-TRONIC reveals itself as extraordinarily multi-faceted, providing the fitting shift characteristic for any and all situations.
The Computerized Up-Shift function means that the transmission will up-shift into the next gear as soon as a certain rpm threshold has been passed in the present gear. In certain driving situations this might not be desired, for instance during especially sporty driving or for instance when encountering a number of tight hair-pin corners. The simultaneous selection of either Sport, Sport+ or DSC OFF Mode utilizing the Drive Dynamic Management button and the number of the M Shift Mode (transmission) will deactivate the automatic up-shift funtion. The transmission will maintain the chosen gear as much as most rpm's (electronically limited) and won't robotically up-shift into the next gear.
The clever coupling of state-of-the-art engine and transmission applied sciences give the B6 Bi-Turbo gorgeous efficiency figures: zero-100km/h in 4.4s (4.5s), and a prime pace of 320 (317) km/h.
EXHAUST SYSTEM - Pure-bred, Sonorous, Light-weight
For the primary time, Alpina has collaborated with Akrapovič on the event of a lightweight exhaust system made out of excessive-power titanium. Trustworthy to the guideline of 'form follows perform', all the system is noted not just for its acoustics and look, but in addition for its technical refinements. In addition to a weight-saving of forty five% compared to the conventional use of stainless-steel, the exhaust system additionally boasts impressive technical details. The engineers from Alpina and Akrapovič have achieved fairly a feat, managing to retain a diameter of two x 70mm throughout the complete size of the exhaust system, regardless of the tough 'packaging'. In conjunction with additional design refinements, exhaust back-strain is diminished to an absolute minimum.
In interplay with the powerful engine, the exhaust system generates a backdrop of deep, sonorous eight-cylinder sound - highly effective, sporty, however never obtrusive, due to clever, controllable exhaust valves. These offer the motive force a particular degree of affect over the sound experience, and could be controlled utilizing the Drive Performance Control. In Consolation+ and Comfort Mode the valves are closed, opening at 3000rpm, whatever the chosen gear. In 1st and 2nd gear decisive use of the accelerator will trigger the valves to open (at approx. 60% load) and the B6 Bi-Turbo to elicit a special symphony from the tailpipes during dynamic bursts of acceleration. As befits the character of the B6 Bi-Turbo in Sport and Sport+ Modes, the exhaust valves remain open at all times.
CHASSIS - Dynamic Consolation
High-performance convertibles and large grand coupés place particular demands on their chassis - requiring distinct ranges of consolation for easy cruising, protected and impartial dealing with at high speeds, and light-footed agility for the moments in between. To be able to do justice to this broad spectrum of requirements, the new B6 Bi-Turbo options the newest digital suspension technologies and comes with Drive Performance Management (electronically adjustable dampers) and Dynamic Drive (energetic roll stabilisation) as standard.
This method has been artfully calibrated by Alpina and is tied into other system parameters controlling steering help, torque cushioning and the Dynamic Stability Management system. That includes pronounced Comfort+, Comfort, Sport and Sport+ modes, the B6 Bi-Turbo transitions effortlessly from cultivated luxury convertible to thorough-bred sports car. Throughout all variables, the Coupé has been set-up to be more sporting and dynamic, and features a rear axle with restricted slip differential as standard.
Specific springs, elevated entrance wheel camber and a subtle adjustment of the toe-in along with a 20" wheel-tyre mixture all serve to provide a very agile chassis set-up. The lightweight 20" Alpina CLASSIC wheels, with MICHELIN PILOT SUPER SPORT tyres in the dimensions 255/35 ZR20 entrance and 285/30 ZR20 rear, contribute considerably to the direct handling and precise steering. Typical tyres are used to advertise trip comfort.
EXTERIOR DESIGN - Thrilling Particulars, Useful Aerodynamics
The BMW 6-Series is marked by a chic and dynamic design as well as wonderful aerodynamic properties. Alpina offers the new B6 Bi-Turbo a singular, powerful appearance which elegantly underlines the sporty character of this lovely coupé and convertible.
The outside components that influence the aerodynamic properties of the B6 Bi-Turbo usually are not simply there for aesthetic causes - their design is topic primarily to functional premises and plays a central role in reaching glorious excessive velocity stability. Take for instance the front spoiler with the built-in carbon fibre entrance splitter. It causes extra air to movement over and across the car, simultaneously lowering the air lots which movement beneath by more than 10%. This leads to a noticeable stabilisation of the entrance-end at excessive speeds and performs a job in decreasing any tendencies to understeer. The front spoiler, along side the rear spoiler, ensures that the B6 Bi-Turbo is very properly 'tethered' overall. Uplift on the entrance axle is diminished by 14% and tends in direction of a value of zero on the rear axle from a velocity of 150km/h. As an alternative of the rear spoiler, the Coupé is also obtainable with a rear wing - which regardless of a powerful visual influence, matches precisely the contours of the rear space and reduces drag.
All these parts also make sure the effective move of air to various cooler teams, such because the inter-coolers and engine cooling system. One particular element: the excessive-performance brakes, with a diameter of 374mm entrance and 345mm rear, are additionally supplied with cooling air by a specifically constructed NACA air intake on the entrance underbody.
The double tailpipes, with a slightly elliptical form in typical Alpina model, are designed in titanium and carry small logos that make discreet reference to the origins of the Alpina exhaust system made by Akrapovič. The rear valence, which attractively and elegantly frames the outlet of the tailpipes, moreover integrates the options of a diffuser.
