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.
While the 2011 Jeep Grand Cherokee wowed the crowds in New York, what lies beneath could be a key to Chrysler's recovery. The new 3.6-liter V6, called Pentastar after the company's five-pointed-star logo, replaces seven – count 'em, seven – of Chrysler's aging engines, and stands as the outcome of several years of development.
