DALLAS – At the recent Texas state fair, Dodge revealed more details about the 2007 Dodge Ram Heavy Duty’s new 6.7L Cummins turbo-diesel engine, which replaces the current 5.9L engine. Producing 350 horsepower at 3,000 rpm and 650 lb.-ft. of torque at 1,500 rpm, the 6.7L engine features an all-new, six-speed, automatic transmission that delivers improved fuel economy and performance. The engine will be available in 2007 Dodge Ram 2500 and 3500 models beginning Jan. 2007. A commercial-use 6.7L Cummins turbo-diesel engine was introduced in early-2006 with the all-new Dodge Ram Chassis Cab, which is available now. The new 6.7L engine is 50-percent quieter and retains more than 40 percent of its components from the 5.9L engine and shares more than 80 percent of its components with the new Dodge Ram chassis cab. The high-performance 408-cubic-inch, inline-six, intercooled, turbo-diesel meets all 2007 U.S. federal and state emission requirements, which require a 90-percent reduction in particulate matter and 50-percent reduction in NOx. Offered for the first time in Dodge Ram Heavy-Duty trucks are features including an integrated exhaust brake, standard Electronic Range Select (ERS), and ‘smart’ tow/haul controls that provide customers flexibility and increased safety when towing heavy loads.
