New York, New York – Chrysler has introduced an all-new line of V6 engines that will improve fuel efficiency across the Chrysler, Jeep and Dodge lineup by an average of eight per cent compared with previous V6 engines. The new 3.6-litre V6, named Pentastar, will ultimately replace seven current Chrysler V6 engines.

The new engine will first be offered in the all-new 2011 Jeep Grand Cherokee, unveiled at the New York International Auto Show.

“Chrysler’s all-new 3.6-litre Pentastar V6 engine will offer our customers improved fuel economy, refinement and increased performance across the Chrysler, Dodge and Jeep vehicle lineup,” said Frank Klegon, executive vice-president of product development. “At the same time, replacing seven current engines with one engine will result in increased flexibility, more efficient operations, and significant cost savings to the company.”

The Pentastar is an all-new design, featuring double-overhead camshafts and a high-pressure die-cast aluminum cylinder block in a 60-degree configuration. In the 2011 Grand Cherokee, it will deliver 280 horsepower and 260 lb-ft of torque, an increase of 33 per cent in horsepower and 11 per cent in torque over its predecessor, while providing a fuel economy improvement of 11 per cent.

The new engine is designed to run on regular gasoline and is fully flex-fuel capable for E85. The company’s new engine plant in Trenton, Michigan will be the lead facility for production, followed by a duplicate new facility in Saltillo, Mexico that will ramp up for the 2012 model year.
