All that power has to come from somewhere, and now its time to talk about the Mercedes-built 3.0-liter Common-Rail Diesel, originally designed for the Mercedes-Benz Groups luxury sedans and SUVs, and now making its first appearance in a Chrysler Group product in North America. This V6 promises efficient, uncompromised power with an expected 30 percent improvement in fuel economy over an equivalent gas-powered engine. Its one of the first new-generation European diesels to hit North America, combining technologies like high-pressure piezo injectors, four valves per cylinder with dual overhead cams and two camshafts per cylinder, intake-port swirl control and variable geometry turbochargers.
