Pentastar V6 starts productionby David Zatz on March 17, 2010 at 2:14 pm EDT While the start date for the Jeep Grand Cherokee which is to be its first home is still reportedly months away, the Pentastar V6 has entered production in the Trenton (Michigan) Engine Plant. Sources say the plant has been operating slowly for quality reasons, producing mere dozens of the engines each week and sending them to intensive testing areas. Chrysler is replacing its entire V6 engine lineup with the Pentastar series, starting with a 3.6 liter version with a listed 280 horsepower, making its reputation for (and actual) quality critical for Chrysler’s future. A ceremony including Governor Granholm will be held at the Trenton Engine Plant on Friday to celebrate its launch. Share me!RedditFacebookTwitterMorePrintTumblrLinkedInGoogle
