Report: Caddy serious about CTS coupe, wagon; Sixteen won't happen

General Motors is "seriously considering a plan" to expand its CTS lineup to include a coupe and wagon, according to Automotive News. GM has long been known to be mulling a CTS coupe, but this latest report suggests the automaker is ready to make it a reality.

The 2008 sedan -- due at the Detroit auto show -- will remain the volume leader in the CTS line, with niche coupe and wagon models targeting consumers with different needs. A wagon could help increase the popularity of the CTS in Europe, where Cadillac is struggling to establish itself.

Auto News also says Cadillac might dump either the STS or the DTS sedan. Executives reportedly feel the company only needs one $50,000 sedan. A competitor to the Mercedes S-Class is not likely any time soon, and a production version of the Cadillac Sixteen won't happen, the report said.
