GM confirmed Wednesday that the next-generation Cadillac SRX will be produced at the GM plant in Spring Hill.

The Cadillac SRX is scheduled to begin production late next year and come to market as a 2016 model.

GM announced last August that it would spend a total of $350 million and create or retain at least 1,800 jobs at Spring Hill to support expansion of the once-shuttered vehicle assembly line, adding two new midsize vehicles.

Those vehicles for Spring Hill were included in negotiations with the UAW for a new contract in summer 2011. This is the first of the planned vehicle announcements.

In addition, the company announced it will invest $185 million to make small gas engines at its Spring Hill manufacturing complex, retaining 390 jobs.

The investment supports GM's all-new Ecotec engine family that will be used by five GM brands in 27 models by the 2017 model year, powering many of the company's high-volume small car and compact-crossover vehicles.

Spring Hill is among six manufacturing locations around the globe that will produce the new engine.

"The new Ecotec engine family represents the most advanced and efficient small displacement gasoline engines in GM's history," said Arvin Jones, GM North America manufacturing manager
