The Cadillac ATS-V Sedan and Coupe track-honed design, chassis and suspension elements complement the twin-turbocharged powertrain, providing true track capability, performance and driver control without modifications or special procedures.
With more than a decade of V-Series production models and the Cadillac Racing program experience, Cadillac has engineered the first-generation Cadillac ATS-V Sedan and Coupe to deliver an agile feel, while maintaining excellent ride quality. The ATS-V incorporates unique performance elements, components from world-class performance automotive suppliers and segment-leading, company-exclusive technology.
The Cadillac ATS-V 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. The ZF Steering Systems electric power steering features greater system stiffness for a feeling of precision and greater driver feedback.
Eighteen-inch wheels wrapped with specially developed Michelin Pilot Super Sport summer-only tires give the Cadillac ATS-V its footprint and enable nearly 1g in lateral acceleration. The lightweight, forged alloy wheels – measuring 9 inches wide in the front and 9.5 inches wide in the rear – are constructed of a low-mass forging that helps reduce un-sprung weight for greater agility and a more direct feel to steering inputs.
In fact, the wheels are 45-percent stiffer than previous generation Cadillac CTS-V wheels, while the Michelin tires feature a tri-compound tread that delivers excellent grip in performance driving situations, excellent ride quality characteristics and extended tread wear.
A Brembo 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.
Segment-best, third-generation Magnetic Ride Control “reads” the road up to one 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.
Segment-exclusive Performance Traction Management (PTM) software was derived from the championship-winning Cadillac Racing program for the V-Series and implements appropriate measures of electronic assistance, matched for driver skill or road condition. Five driver-selectable modes specifically for the track – Wet, Dry, Sport 1, Sport 2 and Race – provide progressive levels of electronic assistance, adjusting traction and stability controls. The standard electronic limited-slip differential translates the PTM software to optimal traction and enables maximum corner exit acceleration. Automatically activated in all five PTM modes, Launch Control manages tire spin to optimize full-throttle acceleration from a standing start.
Cadillac ATS-V specific structural enhancements include:
- Unique shock tower-to-plenum brace
- Strengthened rocker bulkhead
- Stronger rear cradle-to-rocker braces
- A unique aluminum shear panel at the front of the chassis
- V-braces for the engine compartment
The result is 25-percent greater structural stiffness than non-V models, which contributes to more precise handling and more direct steering responsiveness.
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.
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.
Larger prop shafts and greater half-shaft asymmetry (stiffer driver’s side shaft) mitigate power hop during acceleration.
