Powertrain & Engine Architecture
At the heart of the B7 (F01) lies Alpina’s meticulously tuned version of the BMW N63B44 engine. This 4.4-liter twin-turbocharged V8 benefits from significant upgrades over the standard BMW engine, including bespoke engine management software, larger turbochargers, a revised cooling system, and a stainless-steel exhaust system. These modifications boost output to 540 horsepower and 538 lb-ft of torque. The engine utilizes direct fuel injection and double-VANOS variable valve timing for optimized performance and efficiency. The transmission is an 8-speed automatic, also sourced from BMW, but recalibrated by Alpina for quicker shifts and more responsive behavior. This transmission is crucial for managing the engine’s substantial torque output and delivering smooth acceleration.
Driving Characteristics
The B7 (F01) delivers a driving experience that is both refined and exhilarating. The increased power and torque, combined with the optimized transmission, result in a 0-60 mph time of approximately 4.4 seconds and a top speed electronically limited to 193.87 mph. Compared to the standard 750i, the B7 offers a more immediate throttle response and a more aggressive power delivery. While the 750i prioritizes comfort, the B7 strikes a balance, providing a firmer suspension setup and more direct steering feel. The 8-speed automatic transmission is programmed for both comfortable cruising and rapid downshifts, making it well-suited for both highway driving and spirited back-road excursions. The weight distribution is near perfect, contributing to balanced handling.

Optional extras included a rear-seat entertainment system, a premium sound system, and a variety of bespoke interior customization options. Alpina offered a high degree of personalization, allowing customers to tailor the B7 to their individual preferences. The exterior featured unique Alpina aerodynamic components, including a front spoiler, side skirts, and a rear diffuser, along with distinctive 21-inch alloy wheels.
Chassis & Braking
The B7 (F01) features a modified chassis compared to the standard 7 Series. Alpina engineers revised the suspension geometry and fitted stiffer springs and dampers to improve handling and reduce body roll. The car also benefits from a more robust stabilizer bars. The braking system consists of large, ventilated discs at all four corners, providing ample stopping power. The rear brakes are discs, unlike some base 7 Series models which utilized drums. The steering system is a variable-assist rack-and-pinion setup, offering precise control and feedback.
