The cylinder block is made of cast aluminum. It has a stiff rib structure for better rigidity and thereby better sound and vibration properties.

The cylinder block has eight cast-iron cylinder liners molded into the cylinder block. They cannot be replaced.

The coolant jacket goes halfway down the cylinders to ensure quicker heating and thereby reduce hydrocarbon emissions. Certain sections of the coolant jacket are deeper to reduce the risk of the cylinder deformation.
