A-Class; The crankcase of the new diesel engines is made of grey cast iron; the crankshaft is forged steel. In the cylinder head are two overhead camshafts, each of which controls two intake and two exhaust ports via roller cam followers. A chain drives the camshaft on the intake side, which is linked to its counterpart on the exhaust side.

A-Class; The state-of-the-art, lightweight crank assembly in the petrol engines consists of an aluminium crankcase with cast-iron cylinder liners. Valve timing is taken care of by a hollow-bore camshaft made from induction-hardened forged steel and low-friction roller cam followers. A timing chain with a hydraulic tensioner and rubber-coated sprockets drives the camshaft. Hydraulic valve clearance compensation takes place automatically.
