The 2010 Jeep Grand Cherokee was the first home for Chrysler's Pentastar V6 engine. As you may recall, the powerplant was codenamed "Phoenix," and it was charged with replacing seven other engines in 11 models in the Chrysler and Dodge lineups. Along with it being a well-regarded piece of engineering, its sheer ubiquity goes a long way toward explaining how in just 18 months the Trenton, Michigan plant that produces it has cranked out a million of them.
