The 2.5 and 3.0 liter 24 valve V6 engine has four overhead camshafts and are driven by two timing chains. The engine incorporates electronic engine management with distributorless ignition system, sequential electronic fuel injection. It also has two catalytic converters in the exhaust system which includes two oxygen sensors and two catalytic monitor sensors.
Viewed from the driving position, the right-hand cylinder bank is numbered 1 to 3, from the front of the vehicle and the left-hand cylinder bank are numbered 4 to 6, from the front of the vehicle.
The engines include the following
- Vehicles fitted with 2.5L engine 10.3:1 Compression ratio.
- Vehicles fitted with 3.0L engine 10.5:1 Compression ratio.
- 3 Stage variable geometry intake manifold.
- Lightweight valve gear.
- Unique camshaft lift and duration.
- Twin knock sensor engine management control.
- Fully variable camshaft timing (VCT) system.
- Twin mass flywheel (manual transmission).
