Cylinder Block

WARNING: This page is about a different variant/trim than selected.

The light alloy cylinder block is manufactured in one piece with press-fit cylinder bores of steel. Passageways for the lubricating system are also drilled inside the block. The main bearing caps are not separate but integrated in a common bed plate. There are two tunnels integrated in the block for the balancer shafts. Loose non-exchangeable bearing bushings are press-fitted for the inner bearing seats.
