Engines

All BMW ALPINA models feature high-tech, state-of-the art engines. Regardless of whether diesel or petrol, six or eight cylinders – every engine impresses with high power output and torque as well as exceptional efficiency.

BMW, an engine builder par excellence, delivers the basis in form of outstanding power units equipped with the latest technological refinements, plenty of output potential and class-leading features for the reduction of fuel consumption and emissions. Building on the experience and know-how of more than forty years of drivetrain development, the engineers in the ALPINA manufactory leverage the freedom and flexibility that a small series production offers to develop exceptional and exciting engines for a wide range of models.

As a manufacturer of exclusive automobiles, ALPINA has its own ultra-modern development and test centre as well as a large team of developers, engineers and specialists. As a result all engines and in fact every drivetrain component of every BMW ALPINA model is developed and stringently tested to ensure that it withstands the toughest demands placed upon it and that it delivers its full potential in every situation. Naturally all engines comply with the latest and strictest exhaust and emission regulations worldwide, no matter whether in Europe, Japan or California.

8-Cylinder BITURBO Petrol

Cutting-edge BMW engine technology and comprehensive development work carried out by ALPINA, means output and torque are raised to a whole new level.

The new 4.4 litre 8-cylinder engine with Bi-Turbo charging, petrol direct injection and Valvetronic delivers an impressive output of 447 kW (608 hp) between 5750 and 6250 rpm, while the maximum torque of 800 Nm is available from 3000 rpm.

The power output of this high-tech engine unfolds smoothly and with impressive vigour across the entire rpm range. Excellent throttle response and high torque ensure that even at low engine speeds driver inputs are immediately transformed into forward acceleration. In every situation there is a fascinating surge to the car‘s power delivery. In addition to the depth of ALPINA’s engineering expertise a number of significant technical details are responsible for the engine’s power output and performance characteristics – specifically the air intake system, the intercooler / turbocharger configuration and the high-performance cooling system.

The Bi-Turbo charging system comprises two specially developed turbochargers with twin-scroll turbines and large compressor wheels, which are positioned in the V of the 8-cylinder engine. This configuration ensures highly effective use of exhaust gas energy even at low engine speeds resulting in a quick power build-up and more torque at low engine speeds for overall exceptional engine response. All components of the ALPINA air intake system - from the so called raw air intake ducts to air filter housings and clean air intake manifold - have been constructed to maximum effectiveness. Similarly, the high-performance cooling system utilises large volume radiators and optimised piping designed for maximum throughput. An indirect inter-cooler system (air/water/air) facilitates the implementation of short charge-air intake paths – with a main intercooler supplying the two large volume engine-near intercoolers. Together with additional external radiators the system ensures the thermodynamic stability of the V8 Bi-Turbo engine at all times even under the highest loads and ambient air temperatures.

6-Cylinder BITURBO Petrol

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.
