The XTS’s standard 3.6L V-6 is rated at 305 horsepower (227 kW) and 264 lb.-ft. of
torque (355 Nm). Lightweight features help reduce overall weight for greater
efficiency and a more favorable front-to-rear weight balance. Examples include a
composite intake manifold that saves approximately 5.5 pounds (2.5 kg) over the
weight of a comparable aluminum intake and an integrated cylinder head/exhaust
manifold design that saves approximately 13 pounds (6 kg) per engine.
The engines are matched with six-speed automatic transmissions with tap-shift
control.
XTS driving experience
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.
