~$143,000
Engine: 4.4L twin-turbocharged V8
Torque: 800 Nm
0–100 km/h: ~3.5 s
The ALPINA B7 xDrive was one of the fastest production sedans in the world at its debut, achieving a 0–100 km/h sprint in just 3.5 seconds and a top speed of 330 km/h (205 mph). Its 4.4-liter bi-turbo V8 was meticulously re-engineered by ALPINA for increased boost pressure, cooling capacity, and torque spread, delivering immense, refined acceleration at any speed. Throttle response was immediate and smooth, reinforcing the B7’s ability to combine supercar performance with executive-class composure.
Despite its long-wheelbase format, the B7 handled with surprising agility thanks to ALPINA-specific suspension tuning, active roll stabilization, and rear-wheel steering. The bespoke calibration of the air suspension allowed it to lower automatically at speed, improving aerodynamics and stability. Steering was precise, weighted appropriately, and free from the numbness often associated with large luxury sedans. xDrive all-wheel-drive ensured maximum traction in all conditions without compromising the rear-biased feel cherished by driving enthusiasts.
What made the B7 unique was its dual personality. While it offered silent, limousine-like cruising and unmatched ride quality, a simple tap of the throttle could unleash devastating acceleration and a subtly aggressive V8 soundtrack. It was never showy or loud—performance came dressed in restraint. This made the ALPINA B7 a genuine alternative to the M760Li or AMG S63 for buyers who valued rarity, craftsmanship, and dignified speed over brute force and ostentation.
Body Styles
The ALPINA B7 was offered exclusively as a long-wheelbase four-door luxury sedan. Built on the G12 extended architecture, it combined stately proportions with a dynamic silhouette enhanced by ALPINA-specific aerodynamic enhancements such as a front spoiler, rear lip, and diffuser. The elongated rear doors, wide shoulder line, and low stance emphasized elegance over aggression. Its flowing roofline, chamfered trunk lid, and signature multi-spoke wheels gave the car unmistakable presence, whether gliding through city streets or cruising on the Autobahn.
Model Name Meaning (Manufacturer)
In ALPINA nomenclature, the "B" denotes a gasoline-powered model, while the "7" aligns with its position atop the 7 Series range. The B7 badge reflects its role as the flagship performance sedan of ALPINA’s lineup—emphasizing effortless speed, advanced engineering, and understated luxury rather than track-focused aggression.
Body & Interior Colors and Rims
The ALPINA B7 was offered in a curated range of exterior colors, including exclusive ALPINA Blue and ALPINA Green metallics, alongside BMW Individual finishes such as Dravit Grey, Tanzanite Blue, and Frozen Arctic Grey. Chrome or Black Shadowline exterior trim packages gave the B7 either a classic or modern appearance. ALPINA-specific aerodynamic elements were body-colored, preserving the car’s cohesive and elegant profile.
The cabin featured extended Merino leather as standard, with optional full leather packages including instrument panel and door trim. Lavalina leather from ALPINA was also available in select markets. Interior colors included classic schemes like Cognac, Mocha, Ivory, and Tartufo, with contrast stitching and ALPINA logos embroidered into the headrests. Trim options ranged from piano black and fine wood veneers to brushed aluminum and ceramic controls, emphasizing craftsmanship and detail.
Signature 20- or 21-inch forged ALPINA Classic or Dynamic wheels completed the look, finished in silver or anthracite and mounted with high-performance tires developed in collaboration with Michelin. The wheels were engineered to reduce unsprung mass and featured hidden valve stems behind the lockable center caps—an ALPINA tradition. Blue brake calipers with ALPINA logos added a restrained performance touch.

vs Competitors
The ALPINA B7 went head-to-head with performance flagships like the Mercedes-AMG S63, Porsche Panamera Turbo Executive, and BMW M760Li xDrive. While those competitors leaned heavily into aggressive styling or brute-force dynamics, the B7 charted a unique course—delivering similar or better acceleration and top speed while preserving serenity and sophistication. It offered a less flashy, more bespoke experience with a level of chassis finesse rarely found in this segment. Unlike the V12-powered M760Li, the B7’s twin-turbo V8 delivered superior efficiency and sharper responsiveness. In many ways, it was the true connoisseur’s choice in the world of ultra-luxury speed.
