In what's no great surprise to anyone who's been following Chrysler lately, Automotive News is reporting that production of the 3.7-liter SOHC V-6 will end in September. The engine served as the base engine in the Ram 1500 since 2002 and as the upgrade engine in the Jeep Liberty since 2001. The engine also served as the base engine in the 2005-2010 Jeep Grand Cherokee and the recently discontinued Dodge Dakota.
2013 Ram 1500
will feature the company's new 3.6-liter Pentastar V-6 as the base engine, producing substantially more power than the 3.7 with much better fuel economy, aided by a new eight-speed automatic transmission.
The Liberty will be redesigned soon, and is expected to get a 3.2-liter version of the Pentastar among its engine options. Although 200 of the employees of the Mack II plant that made the 3.7-liter V-6 received layoff notices, they will be redeployed to other plants in the Detroit area. Production of the 4.7-liter V-8 built at the adjacent Mack I plant will continue for the time being. However, with output from the new Pentastar coming so close, and continued popularity of the Saltillo, Mexico-built 5.7-liter Hemi V-8, we have to wonder if the days of the 4.7 are numbered as well.
