GENERAL
The V6 petrol engine is a 4.0 liter, 6 cylinder, 60 degrees 'V', unit, with 2 valves per cylinder, operated by a single overhead camshaft. The engine emissions comply with ECD4 (European Commission Directive) and USA Tier 2 Bin 8 legislative requirements and employs catalytic converters, electronic engine management control, positive crankcase ventilation and exhaust gas recirculation to limit the emission of pollutants. The cooling system is a low volume, high velocity system. The fuel injection system is controlled by the Engine Control Module (ECM).

The cylinder block is of cast iron construction with a cast aluminum ladder frame and balance shaft assembly bolted to the bottom of the block. The cylinder heads are cast aluminum with vinyl ester composite camshaft covers. The single piece oil sump is formed from pressed steel. The intake manifold is manufactured from cast aluminum and incorporates a central chamber with six inlet port tracts . The dual wall stainless steel exhaust manifolds are unique for each cylinder bank and a molded plastic acoustic cover is fitted over the upper engine to reduce engine-generated noise.
