Powertrain & Engine Architecture
At the heart of the B8 Gran Coupe lies the Alpina-tuned version of BMW’s 4.4-liter N63B44T3 V8 engine. This engine benefits from significant enhancements over the standard BMW unit, including specially designed pistons, a revised cooling system, and larger turbochargers. These modifications result in an impressive output of 621 horsepower and 800 Nm (590 lb-ft) of torque. The engine employs direct fuel injection, twin-scroll turbocharging, and BMW’s Valvetronic and Double-VANOS technologies for optimized efficiency and responsiveness. The eight-speed Switch-Tronic automatic transmission, also sourced from BMW, is specifically calibrated by Alpina for quicker shifts and a more engaging driving experience. This transmission features a unique selector lever and steering wheel-mounted shift paddles.
Driving Characteristics
The B8 Gran Coupe delivers a remarkably refined yet exhilarating driving experience. The combination of the potent V8 engine and the all-wheel-drive xDrive system provides exceptional traction and acceleration. The 0-60 mph sprint is dispatched in just 3.3 seconds, and the car boasts a top speed of 201.32 mph. While the engine delivers immense power, it’s the way that power is delivered that sets the B8 apart. The torque curve is exceptionally flat, providing effortless acceleration in any gear. The Switch-Tronic transmission is smooth and responsive, and the Alpina-specific calibration ensures that gear changes are both quick and seamless. Compared to the standard 8 Series or even the M8 Competition, the B8 offers a more comfortable ride and a greater emphasis on effortless performance.

Optional extras include bespoke interior customization options, carbon fiber trim, and upgraded braking systems. The B8’s interior is designed to be both luxurious and driver-focused, with a comfortable and ergonomic layout.
Chassis & Braking
The B8 Gran Coupe features a sophisticated chassis designed to deliver both comfort and handling precision. The suspension system utilizes adaptive dampers and air springs to provide a smooth and controlled ride. The car is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The xDrive all-wheel-drive system is tuned for a rear-biased torque distribution, enhancing driving engagement. The B8 also features an active steering system that can adjust the steering ratio based on speed and driving conditions.
Market Reception & Comparison

Legacy
The Alpina B8 Gran Coupe (G16 LCI) represents a significant achievement in high-performance automotive engineering.
