The Cadillac CTS is a family of mid-size premium sport sedans (or coupes, or wagons) that is somewhat closer in size to the BMW 5-Series and Audi A6 but competes more with the 3-Series and A4 families--as well as the INFINITI G37. Compared to most of these other models, the CTS has a different, uniquely American style inside and out that really sets it apart in the market. It's also very competitive with other luxury models when it comes to pricing and features. And while it doesn't yet offer Cadillac's CUE interface that's in the ATS sport sedan and XTS luxury sedan, it offers a very well-designed pop-up navigation system and top-notch premium audio.
Meanwhile the CTS-V models are fully competitive with the likes of the BMW M3 or M5, the Jaguar XFR-S, and the Mercedes-Benz C63 AMG. Cadillac boasts that it was the first production 4-door model using street tires to break the 8-minute barrier on Germany's Nurburgring test track.
