The 2011 Cadillac CTS looks marvelous, with comfortable space for four adults, or five in a pinch. It's got lots of go for the performance enthusiast, and all the bells and whistles. It's offered as a four-door sedan, Sport Wagon or new two-door coupe. With three engine choices from strong-but-frugal to incredibly powerful, manual or automatic transmissions and optional all-wheel-drive, there's a CTS for every taste. Any CTS model compares favorably the luxury-class competition from Germany or Japan.
