W he Alpina thinks, thinks dignified, luxurious and comfort-oriented . All those for whom the in-house automobiles of the white-and-blue large corporation are too little special or noble will be given the best alternative in Buchloe under the sign of the propeller.

If you think Alpina, you can also think racing. Last year, the small series manufacturer, which works closely with BMW, secured the title in the ADAC GT Masters with a B6 GT3 under the direction of Andreas Bovensiepen. Reason enough to celebrate and to break new ground in terms of product policy.

Limited BMW Alpina B3 special model GT3

As long as the new three-seater BMW in Alpina dress is still a long time coming, it will be fans of the Bavarian mid-range model series sweetened life in a very special way: with a deliberately sporty small series of the B3 limited to 99 pieces. Then spring fever is also announced in the cockpit. The interior trim strips, which are normally black in Alcantara, are replaced by bright green lacquered ones and then harmonize perfectly with the always blue-green Alpina stripes of the standard Recaro sport seat shells.

The newcomer baptized B3 GT3 is optionally available in the three solid colors sapphire black metallic, mineral white metallic or alpina blue metallic or exclusively foiled. In the latter case, the 408 hp rear-wheel drive car has the distinctive color scheme of the GT Masters racer and, if required, even its start number and sponsor logos.

Racing feeling in the BMW Alpina B3 GT3

By the way As standard: The 89,899 euro road racer BMW Alpina B3 GT3 has it all. In addition to exotic equipment items such as dive plates on the front apron and the associated front splitter made of carbon, a rear spoiler made of the same material is also part of the aerodynamically effective overall package.

The voice of the real biturbo, which has now been phased out at BMW in the three series -In-line six-cylinder helps in this uncompromisingly sporty environment, a titanium rear silencer supplied by Akrapovic. In terms of driving dynamics, the BMW Alpina B3 GT3 benefits from the Drexler lock, which has been tried and tested in racing, a coilover suspension that can be adjusted in height, rebound and compression, as well as camber, and a high-performance braking system.

Their fixed calipers (six pistons at the front, four pistons at the rear) take generously dimensioned brake discs of 380 and 355 millimeters in diameter at the front andin the back of the pliers. Painted in bright blue, they peek out from behind standard Michelin Pilot Sport 2 mixed-tire, gray multi-spoke forged wheels. We saved the wheelset with Michelin Pilot Sport Cup + tires (5,950 euros surcharge), which is optionally available for the BMW Alpina B3 GT3, as well as the chassis setup optimized for the racetrack with greater camber values ​​for the super test.

During the first test In Hockenheim, the sporty top model of the B3 series should first show what it's made of in road trim. This allows a direct comparison with the values ​​presented by the civil brothers B3 (360 HP) and B3 S (400 HP) in 2009 and 2010. Both cars started with identical tires. And surprisingly, both cars were almost equally fast on the short circuit. Due to the comparatively strong tendency of the S-model to understeer, the lap times on the small circuit in Hockenheim were almost identical at 1:16.1 and 1:16.2 minutes.

The chassis of the BMW Alpina B3 GT3 requires a sure instinct

The BMW Alpina B3 GT3, which has been fundamentally modified on the chassis side, obviously does not fit into the lockstep. The significantly rougher rolling and suspension behavior compared to the series B in everyday life shows a lasting positive effect on the small course. Anyone who brakes corners in good time, turns at a moderate pace and thus minimizes the understeer that is recorded at too high input speeds, will be rewarded for their restraint with a really brisk lap time of 1.14.2 minutes.

A certain amount of getting used to the BMW Alpina B3 GT3 already requires in road configuration. The brightly colored Alpina wants to be understood from the already mentioned circumnavigation of the understeer at the entrance to the curve via the power oversteering when accelerating out of the accelerator pedal, which must be noted in the case of an all too inexperienced stepping on the accelerator, to the braking behavior deliberately designed for greater stability. The ABS tuning itself has only been fine-tuned, but not completely revised. Therefore, the average deceleration values ​​in the test in the standard brake test with an average of 10.4 m /s² are a tad more restrained than in the previously measured standard B3. That is why it is advisable to stay outside the ABS control range in order to achieve the best possible lap time while chasing the times. The extremely precise response of the brake pedal makes it easy to handle.

Good acceleration and excellent handling

During the elasticity values ​​of the BMW Alpina B3 GT3 in the test do not deviate significantly from the level of the series brothers, the acceleration capacity of the minimally performance-enhanced andThe slimmed-down and aerodynamically upgraded B3 and the average speed achieved with normal road tires in the 18-meter slalom are worthy of all honor.

At 69.8 km /h, the Sport-B3 is already very close to that 70 km /h h, which describe the measure of all things when it comes to racing cars with sports tires - and from which the maximum number of points is awarded in the sport auto rating. However, a little driving know-how is also required in this discipline. The conscious use of the accelerator is in fact very popular when the 1,583-kilo athlete has to wag his hat quickly.

Constancy and equanimity tend to slow the BMW Alpina B3 GT3 down. Only those who understand their car as a playmate and sensitively raise and lower their right foot will be rewarded with best times. All sports equipment.
