New Pentastar V-6 Engine to Improve Fuel Efficiency
AUBURN HILLS, MI - Chrysler Group's new Pentastar V-6 engine lineup will contribute to an overall fuel-efficiency improvement across the Chrysler, Ram Truck, Jeep, and Dodge product lineup, according to the automaker. More refined and fuel-efficient, the Pentastar engine will ultimately replace seven current Chrysler Group V-6 engines and utilize advanced technologies from the Fiat alliance such as Multiair, direct-injection, and turbocharging.
The engine will first be offered in the all-new 2011 Jeep Grand Cherokee, launching this year.
In the all-new 2011 Jeep Grand Cherokee, the all-new 3.6L Pentastar V-6 engine will deliver 290 horsepower (216 kW) at 6,350 rpm and 260 lb.-ft. (353 N•m) of torque at 4,300 rpm - an increase of 38 percent in horsepower and 11 percent in torque over its predecessor - while providing an 11-percent fuel economy improvement.
The advanced oil-filter system eliminates oil spills and contains an incinerable filter element for more efficient disposal than typical oil filters. The use of long-life spark plugs and a high-energy coil-on-plug ignition system also helps to reduce maintenance costs.
The Pentastar V-6 is designed to run on regular gasoline, offering a 10-percent reduction in fuel cost compared with premium fueled engines. The engine also is flex-fuel capable, offering users the choice of gasoline or E-85 fuel.
