It looks like buyers of heavy-duty Dodge Ram trucks will be Cummins-powered for a long time to come if they check the box for the diesel engine option.
To have true credibility in the heavy-duty truck segment, automakers almost have to offer the option of a diesel engine. These workhorse engines with their astronomical torque output and relatively lower maximum horsepower ratings tend to provide gobs of torque, better fuel economy, and longer service lives than comparable gasoline power plants. While GM has seen its Duramax diesel relationship with Isuzu on the rocks, and Ford's tumultuous past with Navistar over the PowerStroke diesel, it looks like Dodge and Cummins might be able to give the other two of the Detroit three some long-term relationship tips.
Our colleagues at Autoblog recently reported that Chrysler's relationship with Cummins, which began over twenty years ago (1989), has just been extended. The two companies will reportedly extend their cooperation on diesel powertrain development on a "multi-year basis." Autoblog gave no specifics on how long the Ram-Cummins tie-up is expected to last, but it looks like diesel Ram buyers will be hauling with a Cummins engine for the foreseeable future.
