Fiat Chrysler Automobiles announced today that it will be investing $1.48 billion to retool its Sterling Heights Assembly Plant in order to produce the next generation body-on-frame version of the Ram 1500.

As part of the announcement, FCA indicated that production of the Chrysler 200 sedan will end in December to allow the company to proceed with the changes.

Ram 1500 production is slated to move from Warren Truck Assembly to Sterling Heights Assembly once the retooling efforts are completed. The Warren Truck plant will then be configured to produce the Jeep Wagoneer and Grand Wagoneer SUVs.

Through the first six months of the year, Ram pickup sales have risen 9 perecent while Jeep deliveries are up 17 percent.
