The automaker is putting an extra $200 million into the Cadillac brand and plans to launch at least two new models this year.
The Detroit News first reported on the plans Monday.
Cadillac is also making some other major changes, like expanding its partnership with Tesla, expanding the range of its premium luxury models, and expanding its presence in emerging markets.
The automakers announced the investments in late January and the new investments in February, with the first two models being unveiled in 2019 and 2020.
The Cadillac brand is already one of the most recognizable brands in the world.
The brand is still owned by Chevrolet, but GM is buying a 49 percent stake in the company.
The investment will make Cadillac the second largest automaker in the U.S. behind General Motors.
The company’s share of the auto industry is about 12 percent.
Cadillac will be using some of the money to develop its performance cars and to further develop the brand, said Tom Hall, president of global sales and marketing at Cadillac.
Cadillac has a growing presence in the premium segment of the car market, with sales growing more than 12 percent last year.
Hall said the company plans to expand its offerings with more high-performance models, like the XTS, the SLS and the Cadillac CT6.
Cadillac, which is based in the northern French region of Brittany, has made the XS and CT6 premium sedans available to customers in the United States.
In addition, Cadillac has announced a new crossover SUV, the CTS-V, which will debut this summer in the market that includes the United Kingdom, Germany, Sweden, Italy and Mexico.
The XS, CT6 and XTS are expected to be available this fall.
Cadillac also plans to debut an all-electric crossover, the GX, which has been rumored for several years.
Cadillac said it plans to introduce a new compact sedan, the XPS, in 2020.
