Auburn Hills, Michigan – A new 3.0-litre turbocharged V6 Common Rail Diesel (CRD) engine will debut in the 2007 Jeep Grand Cherokee, announced DaimlerChrysler.

The new diesel has more torque than most eight-cylinder engines and equal acceleration and fuel economy of a small six-cylinder gasoline engine, says the company.

The 3.0-litre CRD diesel produces 218 hp @ 3800 rpm and 376 lb-ft of torque @ 2000 rpm. Built in Berlin, Germany, the new V6 CRD engine offers 33 percent more power and 28 percent more torque than the 2.8-litre predecessor previously offered in Europe.

“Advanced diesel technology has improved over the last several years: engines are quieter and cleaner due to electronic controls, higher fuel pressures and improved after-treatment systems,” said Bob Lee, Vice President, Powertrain Product Team, Chrysler Group.

The common rail direct-injection system has been refined, achieving greater progress in fuel consumption, exhaust emissions and combustion noise. Newly developed Piezo injectors operate more rapidly than the previous solenoid injectors, ensuring a precisely metered fuel supply to the cylinders. Piezo injectors are controlled for load and engine speed. Five injections per power stroke are now possible at a peak pressure of up to 24,000 psi.
