Is this the future?
"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.
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 its 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 Romeos. That ought to serve as an extra bargaining chip in the vital negotiations between Chrysler LLC and the Fiat Group. Under the pending reciprocal arrangement between Detroit and Turin, the Pentastar could end up motivating several new Alfas, including the replacements to the 159 and Brera
, to name just two, while Chrysler reaps the rewards in the form of Fiat Powertrain Technologies' advanced fours. "
