A key component of the car’s dual-purpose performance are Michelin Pilot Super Sport tires
developed specifically for the ATS-V. They feature a tri-compound tread that delivers excellent
grip in performance driving situations, but delivers excellent ride quality characteristics and
extended tread wear.
Also, the V-Series models share the same 109.3-inch (2,775 mm) wheelbase as other ATS coupe
and sedan models, but feature wider front and rear footprints that enhance grip, reduce body
motion in turns and contribute to more direct-feeling steering.
Additional contributors to the ATS-V’s dual-mode driving experience include:
•
A revised multi-link double-pivot MacPherson-strut front suspension delivers a quicker
response and increased lateral control, incorporating new ride and handling links, where
traditional elastomeric bushings are replaced with zero-compliance cross-axis ball joints,
higher-rate springs and a stiffer stabilizer bar – for 50-percent greater roll stiffness
•
The ZF Steering Systems Servotronic II variable-ratio electric power steering gear, with
increased system stiffness offering an improved feeling of precision and greater driver
feedback
•
Cadillac’s five-link rear suspension features reduced roll center migration, stronger
lateral control and effective anti-squat geometry, complementing the front suspension
with greater body motion control. Contributing components include stiffer bushings,
new cradle mounts, higher-rate springs and a stiffer stabilizer bar
•
A standard electronic limited-slip differential supports optimal traction and enables
maximum corner exit acceleration
•
Larger prop shafts and greater half-shaft asymmetry (stiffer driver’s side shaft) mitigate
power hop during acceleration
•
A Brembo high-performance brake system provides durability, consistency and the
capability for track-day performance. The system includes 14.5-inch-diameter (370 mm)
front rotors with staggered six-piston calipers and 13.3-inch-diamter (339 mm) rear
rotors with four-piston calipers.
The ATS-V also features third-generation Magnetic Ride Control and Performance Traction
Management. Five driver-selectable settings include the segment’s only competition-level
settings for stability and traction control.
Magnetic Ride Control “reads” the road a thousand times per second, sending data to magneto-
rheological fluid-filled dampers that can independently control the damping characteristics of
all four dampers. Third-generation improvements enable 40-percent faster damping response.
In fact, at 60 mph, the third-generation magnetic ride control system calculates the optimal
damping force for every inch of the road.
