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 – with an electronic limited-slip differential that splits torque between the rear wheels – complements an advanced HiPer Strut front suspension and standard Magnetic Ride Control real-time damping to give the XTS sure-footed, confident and comfortable ride and handling traits. The rear suspension comprises a linked H-arm design with “air springs.”
HiPer 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 five milliseconds. It replaces conventional mechanical-valve shocks with electronically controlled shocks filled with a magneto-rheological 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 to the driving experience. Like Magnetic Ride Control, XTS borrows the Brembo braking technology from Cadillac’s V-Series of high-performance models.
