New Engines Deliver Performance and Power

The 3.0 CRD engine is a "next-generation" power unit from DaimlerChrysler producing class-leading levels of power and torque - giving it immense towing ability - with efficient fuel economy. Based on the latest Mercedes-Benz technology, Bosch high-pressure fuel injection (1600+ bar), a variable geometry turbocharger and four valves per cylinder, the new V-6 engine meets Euro 4 emissions standards. Additionally, the Jeep Commander's diesel emission system is equipped with a standard diesel particulate filter.

Maximum power is 160 kW (218 hp DIN) and peak torque is 510 Nm (376 lb.-ft.) from just 1600 to 2000 rpm. The accelerator pedal is modified to reduce transmission kick-downs during normal driving but still allow for full pedal travel when quicker acceleration is demanded by the driver.

For customers requiring maximum performance, the 5.7-litre HEMI engine delivers class-leading power and torque: 240 kW (326 hp DIN) and 500 Nm (369 lb.-ft.). Ninety percent of peak torque is available over a broad rev-band (from 2400 to 5100 rpm) for excellent performance while trailer towing or travelling off-road, as well as during regular city and highway driving. To boost fuel economy, the engine is fitted with the Multi-displacement System that deactivates half the cylinders during cruising and light acceleration to increase fuel economy by up to 20 percent, depending on driving conditions.

The 4.7-litre V-8 engine was fitted with numerous improvements and refinements for its application in the new Jeep Grand Cherokee, and these are carried over to the Jeep Commander. An improved exhaust gas recirculation calibration delivers better fuel consumption, and the cast oil pan now provides better noise, vibration and harshness (NVH). Maximum power is 170 kW (231 hp DIN) at 4500 rpm, and maximum torque is 410 Nm (302 lb.-ft.) at 3600 rpm.
