A number of important engineering changes have been made to transform the ATS into the performance version you see above, with Cadillac adding a Brembo high - performance brake system and Magnetic Ride Control, and increasing structural stiffness by 25 percent to enable the car to
tolerate higher cornering loads.
The car stays planted even during
high - speed
cornering, and the rally - bred sedan's suspension compliance means it can
tolerate a lot, including brushing over curbing, before it loses its composure.
