Prototypes for the updated 2018 Ram Heavy Duty with the 6.7-liter Cummins inline-six cylinder diesel engine have been spied testing.
The most interesting aspect of the prototypes is the presence of different looking catalytic converter and exhaust system. Automakers are currently in a torque war in regards in HD pickups and a large part of being able to produce big torque numbers is being able to control the excess emissions that may come along with it.
It’s likely that the new 6.7-liter Cummins diesel engine will produce at least 930 lb-ft of torque seeing as the current leader in the torque race, the Ford Super Duty and its 6.7-liter Powerstroke V8, make a sizeable 925 lb-ft. Knowing FCA’s penchant for big power figures, even 950 to 1,000 lb-ft doesn’t seem out of reach, emissions levels pending, of course.
You can view the spy photos of the 2018 Ram HD diesel prototypes over at TFLTruck. The pickups should debut sometime later this year, perhaps as early as the 2017 New York International Auto Show in early April.
