2023 BMW Alpina XB7 Packs 630-HP Twin-Turbo 4.4-Liter V-8

• The BMW Alpina XB7 2023 gets the same front-end revision as the lower-end X7, while also increasing output from the twin-turbo 4.4-liter V-8 to 630 horsepower.
• BMW claims the XB7 can reach 60 mph in 3.9 seconds and a top speed of 180 mph.
• The XB7 also gets a luxurious interior with an illuminated gear selector and an Alpina steering wheel with blue and green stitching. The starting price is $145,995.

A mid-cycle update to BMW’s biggest SUV, the X7, earlier this year brought a more powerful and efficient engine and a revised front end with slimmer headlights flanking the broad front grille. Now BMW has revealed the most expensive and high-performance version of the X7, giving the Alpina XB7 2023 the same visual upgrades and the most powerful engine in the X7 lineup.

The XB7 continues to use a tuned version of the twin-turbocharged 4.4-liter V-8 found in the X7 M60i, but while the pre-facelifted XB7 makes 612 horsepower, the new version increases it to 630 horsepower. Torque remains the same at 590 pound-feet—a 37 pound-feet advantage over the M60i—and BMW says peak torque arrives 200 rpm earlier, at 1800 rpm, and lasts up to 5600 rpm. The new V-8 X7 also includes a 48-volt hybrid assist that improves engine response and efficiency, and the 4.4-liter Alpina version also gets a unique cooling system.

The motor is mated to an eight-speed automatic transmission that includes a 48-volt starter generator, and the XB7 has all-wheel drive with an electronic limited-slip differential at the rear axle. BMW claims the XB7 can hit 60 mph in 3.9 seconds and run the quarter mile in 12.4 seconds, impressive numbers for a vehicle weighing around 6000 pounds. Top speed is said to be 180 mph if the XB7 is equipped with a package of performance tires and 21-inch alloy wheels, which can be added at no extra cost.

The XB7 uses air suspension with unique Alpina dampers, and the SUV can increase its ride height by 1.6 inches at under 19 mph. Putting the vehicle in Sport mode or driving at more than 100 mph lowers the XB7 by 0.8 inches, while Sport + mode or breaking the 155 mph barrier lowers it by 1.6 inches, though we’re not sure where American Alpina owners will reach these speeds in the colossal they. SUVs.

BMW also says that the Alpina gets reinforced torsion struts for increased rigidity, while stiffer rear axle bushings and the M60i electromechanical anti-roll bars are said to reduce body roll. Rear-wheel steering, also found on the M60i, can move the rear wheels by up to 2.3 degrees in either direction. Braking power is provided by fixed four-piston Brembo calipers mounted on 15.5-inch discs at the front and floating calipers with 15.7-inch discs at the rear. The calipers are painted blue with the words “Alpina” in white.

The XB7 is available with two wheel options. The 21-inch Dynamic Rims can be had with summer rubber or 285 wide rubber at all four corners. Classic 20-spoke, 23-inch alloy wheels are standard and are wrapped in Pirelli summer tires, with tire settings measuring 285 at the front and 325 at the rear. Other design changes for the XB7 include a new front bumper with sculpted air intakes and a body-colored rear bumper.

Inside, the XB7 is adorned with a glass Alpina infotainment control dial, a blue illuminated gear selector, illuminated door frames, and a unique steering wheel upholstered in Lavalina leather with blue and green stitching. The gauges are accented with Alpina blue, change to Alpina green when in Sport or Sport+ mode, and there are three trim options—Myrtle Luxury wood, Piano lacquer, or Natural Walnut Anthracite.

Pricing for the Alpina XB7 will start at $145,995, with shipping set to begin in early 2023.
