Cadillac considering CTS coupe, crossover

General Motors is seriously considering building coupe and crossover versions of its forthcoming 2008 CTS, which will go on sale next year. The proposed plan is designed as an answer to BMW's 3-series which is offered in sedan, coupe, convertible, and wagon variants. GM previewed concept versions of the coupe and crossover to top dealers recently, according to Automotive News. Cadillac General Manager Jim Taylor confirmed new CTS-based models were in the works. One source told the trade publication a third variant -- a convertible, perhaps -- was also possible, though none of the spinoffs had been approved so far. Cadillac is expected to unveil the production 2008 CTS sedan in the near future, and possibly related concept cars, too. In April, GM offered a teaser of what appeared to be a concept version of a new CTS during a 60 Minutes documentary.
