The eight-cylinder engines from BMW stand out thanks to their supreme performance and excellent driving qualities, not to mention their reduced fuel consumption and emissions values: just as consumption is fourteen percent lower, so performance is fourteen percent higher.
These high-tech engines are enhanced further by fully variable valve lift control (Valvetronic), variable camshaft control (double-Vanos), four-valve technology, map-controlled ignition, and highly efficient, variable engine cooling.
The result is silken-smooth refinement plus outstanding power reserves at all times. The fully-variable intake system (DIVA) and its innovative regulation mechanism ensure that the length of the intake manifold can be adjusted perfectly to suit power requirements even at low engine speeds.
The Electronic Differential Lock (EDL) applies brake force with the utmost precision to a rotating drive wheel up to a certain speed and then transfers the torque to the other wheel.
An additional hydraulic pump is responsible for this transferral: if a pre-determined torque value for the wheels is exceeded, the pressure is rerouted via a magnetic valve to a faster-turning wheel, thereby braking it.
