THE S ute's 3.8-litre cast-iron, pushrod V6 engine is the same as used on Commodore sedans. It produces 152kW at 5200rpm and 305Nm of torque at 3600rpm. It uses 12-valve, cross-flow cylinder-heads and low friction technology on moving parts including pistons, rings and the valvetrain. The engine uses 'hot wire' air mass metering and sequential fuel injection as well as high energy distributorless ignition and twin knock control sensors, plus an electric cooling fan. A sophisticated engine management system with computer diagnostics maximises efficiency. A die cast inlet manifold improves air flow and helps increase power, while a stainless steel exhaust prolongs the system's life expectancy. A dual fuel petrol/LPG version is available with automatic versions of the V6.
