The newly updated chassis has revised tire designs for both 19- and 20-inch tires, improving ride comfort while reducing outside noise for a quieter and more comfortable cabin. The XTS can be equipped with Magnetic Ride Control and Rear Air Leveling for extra-sharp handling.
A layered approach to the driving experience relies on new and established technologies, all rooted in a stiff structure. The body is infused with strategically placed, ultra-high-strength steel for strength and crash protection and serves as the foundation for the advanced chassis system.
A smart all-wheel-drive system with Haldex technology splits torque between the rear wheels complements an advanced high-performance strut front suspension and available Magnetic Ride Control real-time damping to give the XTS sure-footed, confident and comfortable ride and handling. The rear suspension comprises a linked H-arm design with air springs.
High Performance Strut is based on the MacPherson strut front suspension design and features dual-path top mountings that separate the transfer of spring and damper loads to the body structure. It improves ride and handling characteristics in four significant ways:
- Provides more linear and communicative steering through improved camber control
- Improves impact isolation on bumps and rough surfaces
- Reduces torque steer
- Improves vehicle sensitivity to tire irregularities and wheel imbalance.
Magnetic Ride Control delivers precise body motion control, "reading" the road every millisecond and changing damping in just 5 milliseconds. It replaces conventional mechanical-valve shocks with electronically controlled shocks filled with a magnetorheological fluid containing minute iron particles. Under the presence of magnetic charge, the iron particles align to provide damping resistance almost instantly.
A premium electric, variable-assist power steering gear is employed with all front-wheel-drive models. It is designed to deliver excellent response and on-center characteristics while enhancing efficiency by drawing energy only when the wheels are turned.
StabiliTrak electronic stability control is standard on all models, along with variable-effort steering and four-wheel disc brakes (front Brembo brakes) with four-channel anti-lock brakes, all features that add important layers of control. Like Magnetic Ride Control, XTS borrows the Brembo braking technology from Cadillac’s V-Performance models.
