2015 Cadillac XTS projects intricate elegance
The Cadillac XTS is one of the most technologically-advanced production cars in the brand’s history. The vehicle delivers space, elegance and a dramatic presence in a unique package that caters to a new generation of luxury customers.
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. A linked H-arm design with “air springs” comprises the rear suspension.
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.
The brake disc rotors are manufactured with a process that protects against rust. It involves super-heating the rotors to more than 560 C for an entire day in a special oven, where the nitrogen-rich atmosphere promotes nitrogen atoms to bond to the rotors’ surfaces, hardening and strengthening them.
