The 2979 cm³ straight-six cylinder engine with direct fuel injection and Bi-Turbo charging produces an impressive 301 kW (410 hp) between 5500 and 6250 rpm and delivers a maximum torque of 600 Nm at 3000 rpm. This enormous pulling power combined with the excellently matched 8-speed sport automatic transmission means that engine response is instantaneous and effortless at all times - a central ingredient for the ALPINA typical driving experience.

A prerequisite for this is the concept of twin turbocharging. This offers the advantage of fast response due to a low mass inertia of the turbochargers (as opposed to a single, large turbocharger) while at the same time allowing for the necessary air throughput required for maximum power output. Engine response and power delivery is sharpened even further by an electronically controlled by-pass valve system. Specially designed and dethrottled induction ducts guide the air with minimum losses from the air intake via the air filter housing to the turbochargers. Optimal utilisation of the power potential is guaranteed by a high-performance cooling package including large-volume intercooler with flow-optimised boxes made from aluminium.

Specific NGK spark plugs as well as a forged steel crankshaft are among the internal engine measures incorporated in the specially cast aluminium crankcase. The engine, equipped with Auto Start Stop function and fully variable valve timing, has a combined fuel consumption in accordance with the ECE norm of only 7.6 to 8.0 l/100 km and emissions of 177 to 186 g/km CO2, depending on model.


The all-wheel drive system uses the technical possibilities of the BMW xDrive system, whose intelligent and dynamic control system distributes output smoothly and fully variably between the front and rear axles in milliseconds, thereby ensuring maximum traction and superior performance in all driving situations. The torque distribution control system, which is interconnected with the engine management and chassis control systems, is performance-oriented. It significantly increases driving dynamics and agility, particularly during high lateral acceleration and guarantees sporty and neutral handling. Besides ensuring optimal traction during acceleration by preventing slip-related losses, the system also permanently monitors the driving conditions and actively distributes torque to always ensure a high degree of propulsion and safety at all times, e.g. on snow or road surfaces with abrupt changes in the friction coefficients.



Exhaust System

The construction and design of the stainless steel exhaust system, developed in cooperation with Akrapovič, guarantees an elegant look and a very emotional soundtrack. The silencer volume is reduced to a minimum in order to optimise the flow of exhaust gases and to save weight - along with other measures the intended result is also a powerful, baritone sound. An intelligent exhaust valve makes it possible to successfully achieve the balancing act between audible pleasure and long-distance comfort. The exhaust valve is closed when the Dynamic Performance Control is set to Comfort mode and opens depending on load and engine speed. In contrast, it is permanently open in Sport mode, generating an exciting sound experience especially under acceleration.
