General information
The V6 petrol engine is a 4.0-litre, 6-cylinder V-engine with a 60-degree cylinder bank angle, 2 valves per cylinder and a single overhead camshaft. The engine's exhaust emissions meet the requirements of the European ECD4 emission standard and the US federal legislation Tier 2 Bin 8; to limit emissions of harmful substances, the engine uses catalytic converters, an electronic engine management system, forced crankcase ventilation and an exhaust gas recirculation system. The engine cooling system has a small volume and a high coolant consumption. The fuel injection system is controlled by the engine control unit (ECM).

The cylinder block is cast iron with a cast aluminum ladder frame and balance shaft bolted to the bottom of the block. The cylinder heads are cast aluminum and feature vinyl ester composite camshaft covers. The one-piece oil pan is stamped steel. The intake manifold is cast aluminum and includes a central receiver with six intake ports. For more information, see Intake Air Distribution and Filtering (303-12A Intake Air Distribution and Filtering - 4.0L) Each bank of cylinders has its own dual-layer stainless steel exhaust manifold. To reduce engine noise, a noise-insulating plastic cover is installed on top of it.
