Alpina’s first SUV for the U.S. market is
here and it comes in the most excessive form possible. We’re talking about the
Alpina XB7, the closest thing you’ll get to a semi-official BMW X7 M. It packs
a 4.4-liter twin-turbo V8 gasoline engine that produces 612 hp at
5,500 – 6,600 rpm and 800 Nm of torque available from 2,000 to
5,000 rpm.
Needless to say, the XB7 is capable of
tremendous performance for an SUV of this size. Namely, it will do 0-100 km/h in 4.2 seconds, cover the quarter-mile in 12.6
seconds and top out at 290 km/h. These figures are achieved with the
standard 21-inch alloys shod with 285/45 R21 performance tires.
Responsible for these impressive specs is
the same 4.4-liter twin-turbo V8 that powers the Alpina B7 Sedan, though
engineers tweaked it further to unleash 12 extra horsepower. The engine is hooked
to the ZF-sourced 8-Speed Sport Automatic Transmission featuring a “complete
redesign of the electronics and mechatronics” by Alpina. More specifically, the
shift points are optimized for driving performance and gear shifts are
considerably more dynamic in Sport and Sport+ modes.
The BMW Alpina XB7 also features an
electronically-variable active limited slip differential on the rear axle, with
a locking torque of up to 1,997 Nm. This is said to improve
traction during dynamic driving by minimizing slip-induced losses and
distributing torque effectively to the wheel with the most grip at any given
time. As with the transmission, the LSD is specifically calibrated to suit the
dynamic character of the BMW Alpina XB7.
Alpina’s engineers also worked on the
xDrive AWD system by adapting the torque distribution to maximize traction and
neutral driving dynamics in all conditions. In addition, the Integral Active
Steering (rear-wheel steering) is standard on the XB7, offering direct steering
response, exceptional feedback and improving overall agility.
Another area Alpina put its mark on is the
standard two-axle air suspension with specific damper and kinematic set-up that
allows for a 1.6-inch (40.6-mm) change in ride height, depending of driving situation
and mode selection. In the sportiest setting, the Alpina XB7 sits 1.6-in
(40.6-mm) closer to the ground for a lower center of gravity.
Also improving handling is the revised
suspension geometry with increases in negative camber. Additionally, the Alpina-specific
dome-bulkhead strut and reinforced torsion struts increase body rigidity while
the electromechanical anti-roll bars of the Active Roll Stabilization system
and stiffer rear axle bushings are said to reduce body roll substantially.
Rounding out the mechanical upgrades are the Brembo four-piston fixed brake
calipers with 15.5 x 1.4-in front brake discs and floating brake calipers with
15.7 x 1.1-in rear brake discs. The calipers are finished in Alpina Blue with
white Alpina logo.
In the looks department, the Alpina XB7
adopts a sharp yet understated body kit featuring a new front bumper with large
air intakes, new rear bumper with stainless-steel sport exhaust system and
small diffusor fins, as well as signature Alpina elements. Those include the
brand lettering in the front bumper and Alpina Classic 20-spoke wheels which
are optionally available in 23 inches.
Inside, the Alpina XB7 features exclusive
details like the ‘Crafted Clarity’ glass application on the blue illuminated
gear selector switch, iDrive controller in Alpina design, Alpina production
plaque, illuminated Alpina door sills and Alpina sports steering wheel
hand-finished in Lavalina leather with trademark Blue/Green stitching. The
performance SUV also comes fitted as standard with the Alpina Myrtle Luxury
Wood interior trim.
Considering that the 2021 BMW Alpina XB7
starts at US$ 141,300 (plus Us$ 995 destination), it comes equipped with pretty much
every option available on the X7. Highlights include the Merino Leather
upholstery, heated Multicontour Seats, Soft-Close Doors, Alcantara
Headliner,Leather Instrument Panel, three-part panoramic glass sunroof, and a
full suite of driver assistance systems. The Alpina XB7 can be ordered in the
U.S. from May 2020, with the first deliveries scheduled for September. It will
be built at BMW’s Spartanburg plant in South Carolina.
