While the 2011 Jeep Grand Cherokee continues to wow the crowds, what lies beneath the hood could be the key to Chrysler's future. The all new 3.6-liter, called Pentastar after the conpany's five pointed star logo, replaces 7 of Chrysler's engines and stands as the outcome of several years of development!
The all-aluminum DOHC Pentastar V6, as applied in the new Jeep, offers a 33% increase in power and 11% improvement in the torque department over the engine it replaces, for a husky 280 horsepower and 260 lb-ft, all while returning 11% better fuel economy and helping Chrysler trim it's overall, range-wide CAFE emissions by two miles per gallon by 2015. But the key to the engine's success could be its flexibility: not only is it designed as a flex-fuel engine, burning either gasoline or E85 ethanol with no effect on either output or emissions (no mean feat in and of itself), but the new Pentastar will find its way into a wide variety of vehicles, including Chryslers, Dodges and Jeeps, but also Alfa Romeros.
