Their superiority is the result of the perfect interplay of their individual components.
They possess four-valve technology with a central spark plug unit, a feature which enables the cylinders to fill to best effect and thereby establishes the basis for increasing power and torque.
The Digital Motor Electronics (DME) regulate and monitor all important functions such as ignition and fuel injection, and they guarantee the best possible performance.
Double-Vanos, double variable camshaft control, delivers optimum valve regulation and fuel dosing, and it sees to it that torque values are impressive at all engine speeds.
Needless to say, fuel consumption and emissions drop considerably thanks to these engineering innovations.
