The new CTS shares platforms with the slightly smaller ATS. Weight and balance were critical, so the new sedan utilizes lots of high strength steel, alloy suspension components and the automaker's first application of aluminum doors to save weight. All told, the new car has shed 244 pounds compared to the base 2013 3.0-liter base model, and it boasts a near 50/50 weight balance like its European rivals. While most cars are loading down the scale, the curb weight of the lightest CTS model is 3,649 pounds (for comparison, the BMW 528i tips the scales at 3,814 pounds while the Mercedes-Benz E350 is 4,012 pounds).
Underpinning the CTS is an independent MacPherson-type front suspension, while the rear is an independent five-link setup. Standard models have fixed damping, but Magnetic Ride Control (MRC), GM's excellent active damping system, is standard on vehicles with 18- and 19-inch wheels. The steering is a ZF rack-mounted electric system with variable assist, and front four-piston aluminum Brembo brakes are standard in all models (the rear brakes are single-piston sliding iron calipers). Wheel sizes, meanwhile, range from 17- to 19-inches, depending on the powerplant and options.
