Our test CTS had the optional performance suspension, and the car felt as firm as one of the high-performance V-Series versions that Cadillac sells, with harsh, jarring responses over bumps. It's not far removed from the suspension tuning on Mercedes' AMG models, like the C63 AMG, which is a firm-riding sport sedan.

The payback, however, is minimal body roll, which is welcome when the road bends. The performance suspension includes thicker front and rear stabilizer bars — as well as a limited-slip differential if you opt for summer tires — but the steering prevents the car from being as engaging as it might otherwise be; steering effort is light and steering feedback expectations remain unmet.

Tires play a significant part in the ride and handling equation, which is why it was unfortunate that our rear-wheel-drive CTS arrived with Bridgestone Blizzak winter tires on its 19-inch wheels. With temperatures in the 50s, spring was well under way when we drove the car. The summer tires that are normally part of the optional Performance Package would have been a better match for the conditions.
