Crankcase

Crankcase

The proven closed-deck design of the aluminum crankcase is used for the V6 models like on the V8 models. In this construction, the housing and coolant ducts form a closed system around the cylinders. This creates a very rigid engine assembly, minimizes cylinder distortion and results in low oil consumption as well as a reduction in the amount of combustion gases that pass by the piston rings into the crankcase (blow-by gases). The lightweight, rigid engines therefore ensure lower fuel consumption and a long service life. The water jacket ensures that the cooling system has sufficient reserves even in the cylinder head, which is subject to substantial thermal loads.

Lightweight construction

The use of aluminum screws for all magnesium parts, e.g. timing-case cover, for screwing together the top and bottom parts of the crankcase and for connecting the engine and transmission, also contributes to a further weight reduction. The new generation of V6 engines also features a fully aluminum, lightweight camshaft adjuster. The timing-case and valve covers, which cover the timing drive mechanism and camshafts respectively, as well as the oil guide housing of the Panamera are manufactured entirely from magnesium.
