Reports are coming in that Ram Truck is doing early testing on a turbo-diesel engine for the Ram 1500, but a proper diesel model isn't likely to happen for several years. Earlier reports suggested that a smaller Cummins or other branded diesels may be an option, but it looks like the small Fiat-owned VM high-tech V-6 is the obvious front-runner.
In an article posted Monday, Allpar.com said it has sources saying that early one-off models have been made with the 3.0-liter V-6 VM Motori turbo-diesel engine (named the VM A630), which already sits inside the new Jeep Grand Cherokee sold in several global markets (and will also come to the U.S. market).
The engine can be tuned to produce more than 400 pounds-feet of torque, and, in a truck platform, it is likely to be able to tow as much as 10,000 pounds.
These early pre-production vehicles could show up in some spy photos if photographers keep their eyes on the tailpipes and fuel-filler caps. We hope to have more soon.
