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 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.

The disclosed fuel consumption and CO2 emissions are measured according to WLTP (Worldwide Harmonized Light-Duty Vehicles Test Procedure) and converted to NEDC (New European Driving Cycle) for comparison purposes. Depending on your country, vehicle related taxes or other duties may be based on fuel consumption and CO2 emissions data which differs from that shown here.
Further information on specific fuel consumption and specific CO2 emissions of new passenger cars is given in „Leitfaden über den Kraftstoffverbrauch, die CO2-Emissionen und den Stromverbrauch neuer Personenkraftwagen” which can be obtained free of charge at all points of sale and from the Deutsche Automobil Treuhand GmbH (DAT), Helmut-Hirth-Str. 1, 73760 Ostfildern-Scharnhausen.
Determined on the basis of the measured CO2 emissions taking into account the mass of the vehicle.
