The Chrysler Group is investing nearly $300 million at a Michigan engine plant to support production of 4.0-liter V6 engines and redesigned 3.8-liter V6 engines. The company is putting $155 million into the Trenton, Mich., engine plant for the 4.0L engine line and $142 million to upgrade the plant's 3.8L engine line. Both lines will feature new tooling, equipment, and quality-control systems. According to Chrysler, 100% of engines coming off the line will be tested for noise, vibration and hardness, and verification of oil circuits by state-of-the-art cold-test stations. Advanced hot-test stations will also be added and workstations redesigned. In addition, the Trenton plant is adopting new workplace practices, in cooperation with the United Auto Workers, to foster creativity and innovation on the plant floor.
