In just 18 months Chrysler workers have cranked out 1 million of their new Pentastar V-6 engines. The engines are produced at their Trenton, Michigan and Saltillo, Mexico assembly plants. There are 1,300 workers at these plants. Two shifts at each plant send these engines out at break-neck speed.
The state-of-the-art engine is the most advanced six-cylinder engine ever produced by Chrysler. It's now available in 11 models across the Chrysler, Jeep and Dodge lineup. It's used in front, rear and all-wheel-drive configurations.
The 60 degree, all aluminum V-6 engine is tuned for specific applications with horsepower ranging from 283 to 305 horsepower. Years ago you were lucky to get 115 horsepower out of a V-6 or inline 6-cylinder engine. The Pentastar has replaced six engines from 2.7-liters to 4.0-liters.
The engine is losing weight. Chrysler's Powertrain organization has reduced major components from 189 to just 32 parts by directly casting parts such as the exhaust manifolds directly into the cylinder head. Previously they had 32 different exhaust manifolds used on a variety of V-6 engines. Previously they used 21 different upper and lower intake assemblies and now there are two upper and two lower assemblies. Additionally, camshaft variations have dropped from 14 to four and just two fuel-rail assemblies are now required. The engine weights about 42 pounds less than the old 3.5-liter V-6 engine and 94 pounds lighter than the old 3.7-liter engine.
All of the new technology built in the Pentastar engine has enabled the manufacturer to remove the exhaust gas recirculation valve and related ports and plumbing. With all the changes this engine meets Ultra-low emission standards plus many more emission standards worldwide.
