According to Truckblog and Chrysler's own blog, Dodge has extended its contract with diesel-engine manufacturer Cummins. Cummins, who has been making diesel's for Dodge since 1989, will be expected to produce the 6.7-liter diesel that will be featured in upcoming heavy-duty Rams. This engine is expected to produce 350 horsepower and 650 lb-ft of torque.
The engine will be optional on 2011 Ram 2500 and 3500 models, and standard on 4500 and 5500 Chassis Cab models. The contract to produce these engines is a multi-year deal. It's not known when the deal will expire.
Chrysler says the new engine will make its peak horsepower at 3,000 rpm and its peak horsepower at 1,500 rpm. It also claims it won't need to selective catalytic reduction to meet EPA emissions standards.
This may not be the world's biggest news, but it may make Ram diesel fans happy. Cummins diesels have been powering the trucks for over 20 years, and in heavy-duty truck circles, customers are almost as loyal to an engine as they are to a brand.
650 lb-ft of torque is not a number to sneeze at, even in a heavy truck. Expect a strong towing capacity, especially since GM is claiming up to 20,000 lbs of towing capacity in its upcoming 2011 Chevrolet Silverado HD.
The heavy-duty truck wars continue to heat up, and it will be interesting to see which one of the Detroit Three emerges as the clear front-runner. What is clear is that all three automakers are continuing to fight it out for customers in this very competitive segment.
