"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 V6 will first be offered in the 2011 Jeep Grand Cherokee producinge an output of 280HP at 6,400 rpm and 260 lb.-ft. (353Nm) of torque at 4,800 rpm from a displacement of 3.6-liters. Chrysler supports that the new V6 offers an increase of 33% in horsepower and 11% bump in torque over its predecessor while providing an 11% fuel economy improvement.
The six-cylinder unit has been designed to run on regular gasoline, offering around 10 percent reduction in fuel cost compared with premium fueled engines.
