All of the CTS drivelines are smooth, quiet and powerful, with the latest technology and advanced electronic controls throughout. Most buyers opt for the automatic, which features a manual shift feature in all models for the first time. Yet the manual is remarkable for its smooth shifting and easygoing clutch. Those who want a true four-door sports car that will run with Porsche 911 can try the CTS-V, a hot rod that looks like a CTS but sounds and accelerates like a Corvette. The CTS-V is a great hot rod, but the other CTS models are far more pleasant for daily driving. We love the CTS's balance of good ride quality and fine handling. We haven't been happy with its austere interior, but Cadillac has tried to soften it a bit and make it more inviting. The CTS is the first GM vehicle with XM NavTraffic, which can deliver continuous, real-time traffic information straight to the navigation screen. The Cadillac CTS is a sophisticated car that belies its sporting potential until you mash down the gas and attack the corners. It has helped reacquaint the world with Cadillac's century-long tradition of technology and design innovation. In short, the CTS presents a real, uniquely American alternative to traditional class leaders like the BMW 3 Series and Audi A4.
