Are you ready for a steady wave of Cadillacs? Parent automaker GM intends to roll out a new vehicle every six months through the next three years, and they're dropping hard cash toward the first two. The Cadillac Lansing Grand River assembly plant in Michigan has received a total $175 million toward the production of the next Cadillac sedans.

The currently unnamed sedans will likely act as replacements for the CTS, ATS, and XTS. According to a GM representative, the automaker is already installing new tools and equipment at the Lansing plant in preparation for the new production line. At the moment, the same plant builds the ATS, CTS, and the Chevrolet Camaro.

While the ATS sedan will discontinue after the 2018 model year, the ATS coupe will still be produced. It'll stick around until Cadillac announces a new line of coupes, at least. We won't see such an idea until 2020, most likely.

This is about two years before this, GM invested $211 million in the plant for new gear, equipment, and even a 32,000-foot addition to the structure, all for future sedan development.

As for what kind of sedan we will actually see come out of this plant, that will be determined in due time. More information on that as it becomes available.
