The interior of the STS is superb, with comfortable but supportive seats that are infinitely adjustable, ample storage space, and superior sound systems. State-of-the-art occupant safety comes standard as well. Entertainment systems include 15-speaker Surround Sound.
The STS is unmistakably a Cadillac, but it's also a four-door performance sedan for people who like to drive. The STS offers a choice of suspensions, from the standard setup designed for smooth, comfortable commuting to an active performance suspension that instantly adjusts to any driving situation, whether cruising through a sea of potholes or accelerating around a sweeping turn. Rear-wheel drive provides the balance and control that serious enthusiasts demand, while all-wheel drive can be very beneficial in bad weather.
