Pistons

Pistons







The pistons are designed as recessed pistons made of aluminium alloy. They have an iron coating (Ferrocout) at the sides to improve abradable characteristics.

The pistons are different on cylinder bank 1 and 2 both in the Cayenne S and Cayenne Turbo. Another difference between the pistons in the Cayenne S and Cayenne Turbo is that the combustion cavities have different depths because the compression ratios of both engines are different.

The piston ring packages for the turbo and naturally aspirated engines are the same.
