The Chrysler Group announced the specifications for the new 6.4L Hemi V8 that will serve as a middle of the road engine for the 2014 Ram Heavy Duty lineup – confirming long-running rumors that the SRT Hemi would end up in a Ram truck. The announcement that the Ram HD didn’t come as much of a surprise but the power ratings did…as the Ram HD 392 cubic inch Hemi offers substantially less power than the similar engine featured in the various SRT8 vehicles.
The 2014 Ram HD 2500 and 3500 will feature a specially designed version of the 6.4L Hemi that has been designed and tuned specifically for heavy duty truck use. The result is a 6.4L Hemi that offers more power than the standard 5.7L Hemi V8 with internal features that will allow this engine to face the rigors of truck use while also offering impressive fuel economy. The problem is that this specially designed truck version of the 392 Hemi offers quite a bit less power than the SRT version with “only” 410 horsepower and 429lb-ft of torque. While this is enough power to give the Ram HD the bragging rights of having the most powerful gas motor in the heavy duty truck segment, it ruffled the features of some Mopar lovers who were fully expecting a 392 Hemi powered Ram with 470 horsepower and 470lb-ft of torque. Of course, ruffled features lead to controversy and that brings about our question of the week.
The output of the new Ram HD 6.4L Hemi makes it the most powerful gas truck in the segment but many Mopar diehards believe that there could have been an even bigger advantage. Does the 2014 Ram HD 6.4L Hemi have enough power? Should the Chrysler Group have tried to preserve more of the power from the SRT model when tuning the engine for truck use?
