General Motors will unveil a wagon version of its successful Cadillac CTS this fall. It will compete with the BMW 3 series and Mercedes C-class wagons. The wagon will go on sale next year and is destined for global sale. Also the coupe version will debut next year.

The SRX crossover will be replaced by a production version of the Provoq concept crossover as a 2010 model. If SRX has disappointed the sales, GM expects that the production version of the Provoq to be sold at around 60,000 to 70,000 units annually.

The current SRX is built on the Sigma architecture, also used for the CTS and STS. The next-generation SRX will be on a new architecture that is a blend of two GM front-wheel-drive architectures, Theta and Epsilon, and will likely be powered by a V-6 engine. In size it would be between the Saturn Vue and GM's Lambda-based crossovers such as the Buick Enclave.
