INTRODUCTION
The Alpina B7 (G12, facelift 2019) builds upon the BMW G12 7 Series platform, a generation known for its technological advancements and luxurious appointments. Alpina Buchloe, a relatively small manufacturer, hand-assembles each B7, differentiating it from standard BMW production models. The facelift introduced in 2019 brought subtle styling updates, enhanced technology, and refinements to the already potent powertrain. This iteration of the B7 is positioned as a direct competitor to high-performance luxury sedans like the Mercedes-AMG S 63 and the Porsche Panamera Turbo, offering a unique blend of German engineering, bespoke customization, and exhilarating performance.
Powertrain & Engine Architecture
At the heart of the B7 lies Alpina’s version of the BMW N63 engine, specifically the B58H variant. This 4.4-liter twin-turbocharged V8 benefits from extensive modifications by Alpina, including bespoke pistons, connecting rods, and turbochargers. These enhancements contribute to the engine’s impressive output of 608 horsepower and 800 Nm (590 lb-ft) of torque. The engine utilizes direct fuel injection and BMW’s VALVETRONIC variable valve timing system for optimized efficiency and responsiveness. The SWITCH-TRONIC eight-speed automatic transmission, co-developed with ZF, is specifically tuned by Alpina for quicker shifts and enhanced driving dynamics. This transmission features a torque converter lockup clutch that engages earlier and more frequently, improving efficiency and reducing slippage. The long-wheelbase configuration and all-wheel-drive system contribute to stable and confident handling.
Driving Characteristics
The B7 delivers a driving experience that is both remarkably refined and undeniably potent. The combination of the powerful V8 engine and the all-wheel-drive system results in blistering acceleration – 0 to 60 mph in just 3.4 seconds. The SWITCH-TRONIC transmission provides smooth and precise gear changes, whether in automatic mode or when utilizing the steering wheel-mounted paddle shifters. While the B7 is capable of aggressive driving, it also excels as a comfortable grand tourer. The long wheelbase and sophisticated suspension system absorb road imperfections effectively, providing a smooth and composed ride. Compared to the standard BMW 7 Series, the B7 offers a more engaging and dynamic driving experience, with sharper steering and more responsive throttle.
Equipment & Trim Levels
The Alpina B7 comes standard with a comprehensive array of luxury features. Interior appointments include premium leather upholstery, wood trim, and Alpina-specific detailing, such as a unique steering wheel and illuminated door sills. Standard equipment also includes a panoramic sunroof, adaptive LED headlights, a premium sound system, and a suite of advanced driver-assistance systems. The long-wheelbase configuration provides ample rear legroom, enhancing passenger comfort. Optional extras include individual leather customization, rear-seat entertainment systems, and a variety of exterior styling enhancements. The B7 is not offered in traditional trim levels; instead, customers can personalize their vehicles through a wide range of bespoke options.
Chassis & Braking
The B7’s chassis is based on the BMW 7 Series platform but features several Alpina-specific modifications. These include stiffer springs, revised dampers, and reinforced stabilizer bars, resulting in improved handling and reduced body roll. The B7 utilizes a multi-link suspension system at both the front and rear axles. Braking performance is provided by large-diameter disc brakes with multi-piston calipers. The front brakes measure 395 mm, while the rear brakes measure 398 mm. The B7 is equipped with ABS (Anti-lock braking system) and other advanced braking technologies for enhanced safety and control.
Market Reception & Comparison
The Alpina B7 has been well-received by automotive critics, who praise its blend of performance, luxury, and exclusivity. Reviewers consistently highlight the engine’s power and responsiveness, as well as the B7’s comfortable ride and refined interior. Compared to other high-performance luxury sedans, the B7 offers a unique proposition – a more understated and sophisticated alternative to the more overtly aggressive styling of some competitors. Fuel economy, while not a primary concern for B7 buyers, is respectable for a vehicle of this size and performance, averaging around 21.2 US mpg in combined driving. Reliability is generally considered to be good, benefiting from the robust engineering of both Alpina and BMW.
Legacy
The Alpina B7 (G12, facelift 2019) represents a high point in the brand’s history, showcasing its ability to create truly exceptional automobiles. The combination of a powerful engine, sophisticated chassis, and luxurious interior has cemented its reputation as a desirable and collectible vehicle. On the used car market, these models command a premium price, reflecting their exclusivity and performance capabilities. The B7’s powertrain, while complex, has proven to be relatively reliable with proper maintenance, making it a viable option for discerning buyers seeking a high-performance luxury sedan.
