In a brief press release Cadillac announced its lineup for 2010 Detroit Motor Show which includes the production version of CTS-V Coupe, and an all-new concept. Cadillac says this model “advances the brand’s Art & Science philosophy that has included a series of acclaimed concept cars in recent years, such as the Cadillac Sixteen, CTS Coupe Concept and Converj“. The company has only released one not-so-revealing picture of this car you see above, but some say it’s the Caddy XTS, a large luxury saloon rivaling Mercedes S-Class and BMW 7er. Expect more details to be revealed as we approach the motor show.
