"The slick nine-speed auto is a big help. The electrically-boosted brakes, however, proved disconcerting -- an uncanny valley of muted feedback made it tough to stop accurately and consistently at a fixed point before a stoplight. And so too did the electrically-assisted power steering, which was a touch too light in all conditions, although admirably accurate. It features a vibration damper to remove unwanted column jitters, which may cause some of the isolation. GM makes some of the best racks in the business, approaching the feel of a good old hydraulic rack in some applications. The XT4's rack is acceptable but not notable. The all-wheel-drive system, available on all trims, is nifty, too. It's a twin-clutch design, able to shift power from side to side the legit way, and paired with a rear axle disconnect system, allowing the driver to lock the car in front-wheel-drive mode for better efficiency.
"The ride, however, is a perfect compromise. Continuously-variable damping is available on Sport models, but the conventional dampers on the Premium Luxury model are well calibrated. The ride is comfortable without being overly coddling –- somewhere, nebulously, between Lexus and BMW. Just as it should be. It's a rigid platform, with some elements solid-mounted to the chassis and some isolated by bushings, like the rear five-link suspension cradle. The only bad handling habit we noticed in a thoroughly typical freeway and suburban drive route was a bit of head-tossing lateral motion when hitting an imperfection going around a corner. Brake dive and other motion sickness-inducing traits are mostly absent."
