    A double turbine torsional damper with centrifugal pendulum which adapts to engine speed helps to minimise vibrations in four-cylinder operation and enhances the impression of comfort experienced by the vehicle occupants. With its own unique shape, black diffuser insert with three fins as well as the two chrome-plated twin tailpipes of the AMG sports exhaust system, it gives a distinctive finishing touch to the vehicle. Very Similar from Car-Revs-Daily In all other operating modes a combination of onboard network and generator management enables the generator to be kept at a low voltage.

    Its newly developed AMG 5. Its fuel consumption of Forming part of the third-generation of the SLK launched in March, the new top-of-the range AMG model already demonstrates its individuality even at first glance: Key figures at a glance: In line with its "AMG Performance " strategy, with the new V8 unit Mercedes-AMG is meeting its promise to continue to reduce both the fuel consumption and emissions of new models over the next few years — while reaching new heights with the central brand claim of "Driving Performance".

    At the same time, AMG is also demonstrating its social responsibility with the M Distinguishing features versus the M include the new intake air ducting, new cylinder heads, the modified valve drive, an adapted oil supply system and an optimised crankcase. Exclusive combination of advanced technologies The high-tech M powerpack enthrals with a combination of advanced technologies which is unequalled anywhere in the world.

    No other petrol engine features direct injection at a pressure of bar, spray-guided combustion and piezo injectors, all in conjunction with map-controlled cylinder shut-off, an all-aluminium crankcase with "spectacle" honing, four-valve technology with continuous camshaft adjustment, a high compression ratio of All of these measures lead to high thermodynamic efficiency, which is a precondition for high fuel efficiency and low exhaust emissions.

    In similar form this technology is also used in the approx. As efficiency also plays a major role at the pinnacle of motor racing, two or four of the eight cylinders are cut off e. With a fuel consumption of The cylinder shut-off function is available over a wide engine speed range from to rpm if the driver has selected transmission mode "C" — Controlled Efficiency.

    The AMG main menu in the instrument cluster informs the driver whether cylinder shut-off is active, and whether the engine is currently running in four or eight-cylinder mode. No less than Nm of torque is still available in four-cylinder mode — enough power to ensure plenty of acceleration in most driving situations. As soon as the driver has a need for more power and leaves the partial load range, cylinders two, three, five and eight are activated.

    The switch from four to eight-cylinder operation is immediate and imperceptible, leading to no loss of occupant comfort whatsoever. At an engine speed of rpm the activation process takes no more than 30 milliseconds. Valves closed, fuel delivery and ignition deactivated This is made possible by intelligent interaction within the highly effective engine management system, with 16 hydraulically compensating elements and a complex oil supply system in the cylinder head.

    The compensating elements are integrated into the cylinder head, and keep the intake and exhaust valves of cylinders two, three, five and eight closed when cylinder shut-off is active. At the same time their fuel supply and ignition are deactivated. This not only enables the load-change losses of the four deactivated cylinders to be reduced, but also increases the efficiency of the four remaining cylinders. This is because the operating point is transferred to the higher load range.

    The compensating elements are compact and lightweight, allowing taut valve train operation and engine speeds up to 7, rpm. The low dry engine weight of just kilograms is the result of uncompromising lightweight construction methods. The bearing covers for the main crankshaft bearings are of grey cast iron, and are bolted to the crankcase, as well as on the sides, for high rigidity.

    The piston rings are carbon-coated to minimise internal friction and optimise the wearing characteristics. Cast-in Silitec cylinder liners ensure low friction for the eight pistons. So-called "spectacle" honing is another measure to reduce friction and therefore fuel consumption: As honing would no longer be possible with the cylinder head installed, a jig resembling spectacles is bolted to the crankcase. The cylinder liners distort as if the cylinder head were in place, and are only then given their mechanical surface treatment.
