INTRODUCTION
The Alpina B8 Gran Coupe (G16 LCI) is a high-performance four-door coupe based on the BMW 8 Series Gran Coupe. Introduced in 2022 with a significant facelift, the B8 builds upon the already luxurious and capable 8 Series, injecting Alpina’s signature blend of power, refinement, and exclusivity. The “LCI” designation refers to the Life Cycle Impulse, BMW’s term for a mid-cycle refresh. This variant, equipped with the 4.4-liter V8 engine producing 634 horsepower and an 8-speed automatic transmission, occupies the top echelon of the B8 range. It’s designed for drivers who demand both exhilarating performance and long-distance comfort, offering a compelling alternative to traditional super-sedans and grand tourers.
Powertrain & Engine Architecture
At the heart of the B8 Gran Coupe GT lies Alpina’s version of the BMW N63 engine – a 4.4-liter twin-turbocharged V8. While based on the BMW unit, Alpina extensively modifies the engine, including bespoke pistons, connecting rods, and turbochargers. These changes, along with a revised cooling system and exhaust, contribute to the increased power output of 634 hp and 850 Nm (626 lb-ft) of torque. The engine utilizes direct fuel injection and features Alpina’s signature Double-VANOS and VALVETRONIC variable valve timing and lift systems for optimized efficiency and responsiveness. The 8-speed automatic transmission, dubbed “Switch-Tronic,” is also heavily modified by Alpina. It features a unique software calibration for faster, more precise shifts, and includes a dedicated Sport+ mode for aggressive driving. The transmission is designed to work seamlessly with the engine’s power delivery, providing smooth acceleration and effortless cruising.
Driving Characteristics
The B8 Gran Coupe GT delivers a driving experience that is both exhilarating and refined. The substantial torque output, available from 3500 rpm, provides effortless acceleration in any gear. The 0-60 mph sprint is dispatched in just 3.1 seconds, and the car continues to pull strongly to its electronically limited top speed of 205 mph. The Switch-Tronic transmission contributes to the smooth and responsive feel, with quick shifts and intelligent gear selection. Compared to the standard 8 Series or even the M8, the B8 offers a more relaxed and compliant ride, thanks to Alpina’s suspension tuning. While still capable in corners, the B8 prioritizes comfort and stability over outright track performance. The all-wheel-drive system provides excellent traction in all conditions, enhancing both acceleration and handling.
Equipment & Trim Levels
The B8 Gran Coupe is exceptionally well-equipped as standard. Interior appointments include Lavalina leather upholstery, Alpina-specific interior trim, and a premium sound system. Standard features also include a comprehensive suite of driver-assistance systems, such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. Optional extras include a panoramic sunroof, upgraded leather options, and a bespoke Alpina interior design package. The B8’s interior is designed to be a luxurious and comfortable space, with a focus on high-quality materials and meticulous craftsmanship.
Chassis & Braking
The B8 Gran Coupe utilizes a modified version of the BMW 8 Series chassis, with Alpina-specific suspension tuning. The suspension features adaptive dampers and a rear air suspension system, providing a comfortable ride while maintaining excellent body control. The braking system consists of ventilated discs at all four corners, with large calipers for powerful stopping performance. Alpina also incorporates a 4-wheel steering system, which enhances agility at low speeds and stability at high speeds.
Market Reception & Comparison
The Alpina B8 Gran Coupe has been well-received by automotive critics, who praise its blend of performance, luxury, and exclusivity. It is often compared to the BMW M8 Gran Coupe, with the B8 generally being favored for its more comfortable ride and more refined interior. Compared to other high-performance sedans, such as the Porsche Panamera Turbo S, the B8 offers a unique combination of German engineering and bespoke craftsmanship. Fuel economy, while not a primary concern for buyers in this segment, is respectable for a vehicle of this performance, achieving around 19.9 US mpg in combined driving.
Legacy
The Alpina B8 Gran Coupe (G16 LCI) represents a continuation of Alpina’s tradition of creating unique and high-performance automobiles. The N63 engine, in its Alpina-tuned form, has proven to be a reliable and durable powerplant. While long-term reliability data is still emerging, early indications suggest that the B8 will hold its value well in the used car market, appealing to collectors and enthusiasts who appreciate its exclusivity and performance pedigree. The B8 Gran Coupe stands as a testament to Alpina’s commitment to automotive excellence, offering a compelling alternative to mainstream luxury performance vehicles.
