Jordie pointed out that Dodge’s “body builder” documentation now includes a CNG (compressed natural gas) Hemi, available on Ram 2500 pickups. While none of Detroit’s Big Three are new to CNG, having made it available to fleets numerous times in the past, this may be a first for the Hemi.
The engine, coded EZF, is available only with the 66RFE automatic transmission, long bed, crew cab, and 3:373 axle ratio, in ST and SLT trim; the GVWR is 8,800 lb, the same as with the standard Hemi, but the payload is reduced due to a higher base weight (the system appears to add around 780 pounds, most likely due to the tank weight).
