7 February 2002
At the Chicago Auto Show, Dodge unveiled the new Cummins Turbo Diesel engine for the 2003 Dodge Ram Heavy Duty 2500/3500 series pickup trucks. The inline six cylinder, 5.9-liter engine produces a 555 lb-ft of torque at 1,400 rpm and 305 hp at 2,900 rpm.
The new Cummins Turbo Diesel incorporates a high-pressure, common-rail fuel system. This system injects a small pilot injection of fuel, which results in reduction of engine noise. The use of pilot injection also provides starting capability similar to gasoline engines.
The new engine has an average major overhaul interval of 350,000 miles and trailer towing rating of 23,000 lbs.
The new Cummins Turbo Diesel engine will be available in the all-new 2003 Dodge Ram Heavy Duty which will begin production in the summer of 2002 at the Saltillo, Mexico and St. Louis North Assembly Plants.
Since 1989 the Cummins Turbo Diesel engine option has been sold with nearly 75% of Dodge Ram 2500 and 3500 pickup trucks, selling over 860,000 to date.
