Chrysler recently filed a trademark on the name, and logo for EcoDiesel. No where does it explicitly say that it is for the Jeep, but because we know that the Grand Cherokee will run with a 3.0-liter diesel, it seems like the only logical option.
To sell the diesel over other fuel efficient choices such as hybrids, Jeep has tacked on the Eco prefix to highlight the engines fuel economy.
In European markets, the Grand Cherokee is already available with a 3.0-liter diesel V-6 making 224 hp and 406 lb-ft of torque, and we expect the U.S. version will get the same engine.
