The folks over GT Spirit got their hands on a brand-new ALPINA B5 BiTurbo. The new B5 by ALPINA enhances the aggressive look of the current 5 Series by offering its own treatment. Similar to what we have seen on the B7, the new B5 offers a blend of luxurious performance, elegant styling, sporty handling and exclusivity.

To find out how the B5 BiTurbo handles itself and to see more photos, let’s have a look at the GT Spirit review.

“ALPINA B5 represents an alternative to the BMW M5, but will continue to differentiate itself from the M5 with its traditional branded elements, such as the oval four tailpipes or the larger air vents incorporated into the bumper.

The standard power-train setup includes a direct-injected 4.4 liter twin-turbo “N63″ V8 punching out 407 horsepower and a stump-pulling 600 Newton-meter of torque between 1,750 and 4,500rpm, while peak horsepower appears between 5,500 and 6,400rpm. Our test car arrived fitted with the automaker’s new super high-tech, buttery-smooth and lightning fast eight-speed automatic (ZF 8HP70). Stock performance figures? The 550i in its standard form has a maximum speed of 250km/h and 0-100km/h in five seconds.

Generating 507hp at a modest 5,500rpm, and with maximum torque of 700Nm available from 3,000 to 4,750rpm, the V8 power-plant inside the Alpina B5 BiTurbo provides more than enough additional performance, pace and acceleration. Upgrades have been realized by swapping the stock twin-turbo for two Honeywell-Garrett turbochargers, which sit inside the V of the two cylinder banks, working in parallel to force-feed the aluminum engine.

Compared to its super-charged predecessor, this engine configuration delivers more torque over a broader range and improves throttle response at lower revs. This is achieved merely because of the basic setup of the 550i, being more sophisticated it provided a leap forward for possible engine enhancements. Additionally, an optimized indirect inter-cooling system with a short intake and a stainless steel exhaust system featuring two double-ended, polished tailpipes are outfitted to the luxury sedan.”

    well the 550i is a lemonade car and Alpina made it a fresh squeezed lemonade but you pay for it dearly at the cash register.
    Overall the 535i is the better car and with a few modifications that can easily be turned into a much better car then the 550i. I would like to see the Alpina 535i and drive that against the 550i.
    The F10 is a wonerful car but it is a bit softer on the handling and steering then the BMW name would suggest. Even the sport package and active handling does not help as much as you would think.
    It needs the usual tuner tricks which Alpina successfully applied. Shorter and stiffer springs, modified camber/caster alignment, non-run flat tires, and a software upgrade for both engine/transmission/steering.

    A combination of these can be done with Dinan or other tuners, no need to go to Alpina and pay the price to them. Their Wood insert for example is simply disasterous, looks plastick and reminds me of the early 90’s Infiniti/nissan and Mazda models.  Leave the wood out of the cars unless their name is RollsRoyce or Bentley.

    The switchtronic buttons on the steering wheel are an another Alpina “trick” which looks and works less then factory paddle shifters,  but cost is extremely high.

    Alpina really sunk down to a tuner category and it might not be their fault. Simply BMW creates such good cars, that unless they dump a load of money into research and development, they will not be able to create better.  In fact many of their mods are undesirable as the BMW version is better, nicer, works and cheaper.

    At the end of the day, an //M model now is much more desirable then the Alpina Schnitzer or any other tuner modified cars.

    Dinan does not sell a car, rather a mod package with warranty and this makes it much better. I can see their business blooming and Alpina’s business shrinking in a future.

    thats bull,,,I find all alpina cars somewhat better than usual bmw cars…but honestly the truth is neither M nor alpina does it for me…G-power is the real deal….

  3. This B5 alpina sounds OK, but i think this M5 should be a better bang for the buck.
