    Alpina B5
    Test date 29 June 2010

    What is it?


    It's the new Alpina B5 Biturbo, the latest creation from the BMW-based manufacturer and the first chance we’ve had to sample a 'performance' version of the new 5-series.

    Recent Alpinas have avoided using the same engines as M division products, but the B5 will come pretty close to going head to head with the forthcoming M5. It shares the same basic 4.4-litre V8 engine (the inlet set-up is different), equipped with two retuned turbochargers.

    In Alpina tune the unit produces a flat 500bhp and 516lb ft. That's enough, says the firm, to take the car from 0-62mph in 4.7sec and onto a gloriously unrestricted 191mph.

    Unlike the M5, which is likely to use a dual-clutch transmission, the B5 gets an eight-speed automatic. But the unit has been developed by Alpina and ZF, and it uses a trick way of speeding up shifts when you're in one of the car's sportier modes.

    Instead of merely retarding the engine timing, the B5 uses its direct injection tech to merely cut off a cylinder or two. Alpina says the system cuts gearshift times in two, to around 180ms.

    What's it like?

    Jaw-droppingly fast. We drove the B5 from Alpina's base in Buchloe to the UK - in time for its appearance at the Goodwood Festival of Speed - and with an empty stretch of autobahn in front of it, it's supercar quick.

    Alpina's claim of 0-62mph in 4.7sec feels conservative - and as for the top speed, well, we saw an indicated 190mph with three and their luggage aboard, and it was still pulling strongly.

    Truth is, though, that making a 5-series with this engine feel strong on a motorway was never going to be the biggest challenge faced by Alpina's engineers. More testing is the task of making it handle on poor surfaces and twisty roads, and here the firm's modifications - lower suspension, non-runflat tyres and comprehensive reprogramming of BMW's adjustable dampers - pays off.

    We wouldn't say the B5 has precisely the same level of agility and subtlety as Jaguar's XFR - but it's not far off it at all, and that means it's very good indeed. Revised steering programming makes the wheel feel lighter at low speeds than a 5-series, and weightier when you're pushing on, and it's a more satisfying set-up than BMW's.

    With the car in Sport or Sport+ set-up the ride is firm but still compliant (no runflats, remember, just Michelin Pilot Sport 2s, or Pilot Super Sports on the final cars) and body control is excellent.

    That trick transmission works well, too; we can't think of many dual-clutch units that beat it on speed and smoothness. The engine has massive urge from beneath 2000rpm, and if you push on it makes a great Nascar-esque soundtrack. It's perfectly docile for everyday use, though; cruise along at 80mph (barely 1900rpm) and it's silent.

    Should I buy one?

    At around £70k, the B5 will sit above the Jaguar XFR on price, but beat it hands down on exclusivity. Even our car - production prototype number one - was beautifully finished, the spec is relatively generous by BMW standards and Alpina can also offer a personal service matched by no mass manufacturer.

    Of course, you could be tempted to wait for the M5, which will offer a more hardcore experience but, almost inevitably, more compromises on ride quality to boot. But if you're more sold on a 5-series than an XF, we'd be sorely tempted to put down a deposit now. Even by Alpina's relatively high standards, this is the firm's most complete package ever.

    Re: First Drive and photos of F10 Alpina B5 BiTurbo Sedan

    Just can't wait to see the new M5. 

    Btw: for those who are afraid that the new M5 is going to have a bad exhaust sound, maybe some good news. Apparently one of the priorities of development is now to achieve a more "appropriate" sound for the M5 compared to it's engine siblings, X5/X6M. Let's just hope that this rumor isn't just the same bag of hot air I got regarding the X5/X6 M exhaust sound software update.  

    Can you imagine ? The M GmbH person I contacted again about it...again...didn't even have the decency to reply.  He actually promised me an answer to my first inquiry.

    RC,

    how do you believe will the F10 M5 fare against the Panamera Turbo (PK)? With this I mean chassis and engine performance.


    Re: First Drive and photos of F10 Alpina B5 BiTurbo Sedan

    I would lie if I'd say I know. I can't even take a guess. My "contact" works for BMW, not for M GmbH, he only has rumors, no facts. The benchmark for the new M5 seem to be Panamera Turbo, Mercedes E63 AMG and Audi RS6. This is all I know. They also want to keep the weight below 2 tons. Not sure if this is possible though. Power should be around 570-580 HP. I also heard that BMW M GmbH is going to offer a Vmax raise to 320 kph.

    Re: First Drive and photos of F10 Alpina B5 BiTurbo Sedan

    So now the Panamera Turbo is lumped into the group with M5, E63 etc and not the big sedans like S class and 7? I am guessing Porsche was the only one thinking Panamera competes with the S-Class.

    Without awd, the new M5 would be hard pressed to match the sheer acceleration of the Panamera Turbo no matter how much power BMW can squeeze from the twin turbo V8. Only saving grace would be M making the car handles much better than the others.


    Re: First Drive and photos of F10 Alpina B5 BiTurbo Sedan

    I'm very curious about the new M5. I don't think it is going to make it into my garage because my wife hates sedans and we need a AWD family car for winter vacations/trips but the new M5 is going to be the hell of a competitor for the Panamera Turbo, especially when it comes to performance, comfort and...important for Germany...public perception (I started to call this "envy factor" ).

    I have same info about power. Also M5 will be will have similar front to 5 series with M package, only center air intake will be fliped upside down - like M3 have. Also rumours are M6 will be a little more powerfull than M5. 

    Thanx temm for photos Smiley

    Re: First Drive and photos of F10 Alpina B5 BiTurbo Sedan

    I think that the new bi-turbo technology BMW M GmbH is using for the X5/X6 M and new M5, is just too new to get a decent sound. It will take some time until BMW learns how to achieve a proper exhaust/engine sound. With modern technology/electronics and clap controlled exhaust systems, this shouldn't be a problem for long.

    I hope you're rightSmiley

     

    Here's the full Alpina B5 pressrelease:

    The finely honed balance between athleticism, comfort and every-day luxury that has defined ALPINA automobiles for decades reaches a new dimension in the BMW ALPINA B5 Bi-Turbo. Five different generations of 5 Series-based ALPINA automobiles have been developed in the last 35 years, revealing to those in the know a unique and exclusive driving experience. The sixth generation draws from the finest ingredients provided by those previous generations to create a mouth-watering palette of characteristics for the most discerning of drivers in the high performance luxury saloon segment.

    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 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'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 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 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 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 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 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 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 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 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'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'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 – Brilliantly Balanced High Performance

    The overall harmony and the accomplished manner with which the B5 Bi-Turbo'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.
