The standard 2.0L Twin-Scroll Turbocharged 4-cylinder produces a vivacious 237 hp and 258 lbs.-ft. of torque, paired with a smooth-shifting 8-speed automatic transmission.
Premium Luxury and Sport trims offer the 2.7L Dual-Volute Turbocharged engine that amps output up to 310 hp and 350 lbs.-ft. of torque. This engine is paired with a 10-speed automatic transmission and allows for a 0-to-60 mph sprint in just 4.8 seconds.

The Luxury trim establishes the CT4's premium character with 17” alloy wheels, LED lighting inside and out, Pitch Dark Night Inteluxe® seating and surfaces with heated front seats and steering wheel, and an available Sun and Sound Package. That adds a power sunroof and an upgraded Bose® premium sound system. Wireless phone charging, dual-zone automatic climate control, and an 8” HD infotainment display all come standard. All-wheel drive can also be chosen in lieu of the standard rear-wheel setup.
Premium Luxury builds upon that strong foundation, and upgrades with larger alloy wheels, rain-sensing wipers, LED interior Radiance Lighting™, 12-way power adjustable front seats in genuine leather, aluminum center console trim, and heated, power-adjustable mirrors. This trim also unlocks the option for the 310-hp 2.7L Dual-Volute Turbocharged engine and Super Cruise®, as well as a Sky Glass™ roof and advanced driver assistance packages.
The Sport trim takes on a more aggressive personality through a unique performance-styled front fascia, black mesh grille, 18” Pearl Nickel-finished wheels, and gloss black exterior accents from window moldings to rocker extensions. Inside, alloy sport pedals, a thick rim steering wheel with paddle shifters, and supportive 18-way performance front seats complete its athletic feel. Available Brembo® V Performance front brakes with red or blue calipers, additional wheel designs, Super Cruise®, and premium technology packages make the Sport trim the most engaging CT4 for enthusiastic drivers.

The CT4's rear-wheel-drive architecture delivers balanced handling and responsive steering, while you stay in control using the standard Driver Mode Selector. You can switch between Tour, Sport, Snow/Ice, and customizable My Mode settings to adjust your CT4’s behavior to the road ahead.
Available Brembo® V Performance front brakes provide stronger stopping power, and the Sport model's suspension and steering enhancements create a noticeably sharper driving experience to go with its assertive looks and feel.

The CT4 seats up to 5 passengers and blends driver-focused ergonomics with premium craftsmanship that stands out in its segment. With 42.4” of front legroom and 33.4” in the 2nd row, everyone rides comfortably.
The Premium Luxury and Sport trims indulge front passengers with leather seating and available 18-way sport seats with heating, ventilation, and power lumbar massage. Touches like sophisticated aluminum trim, a cabin humidity sensor, and a power Sky Glass™ roof result in an environment that feels unmistakably Cadillac.

An 8” HD infotainment display, wireless phone charging, and a premium 8-speaker audio system come standard in the CT4, while available upgrades include a 12” reconfigurable digital instrument cluster, Bose® 14-speaker surround sound, embedded navigation that responds to voice commands, and Super Cruise® hands-free driver assistance.
These technologies combine intuitive connectivity with effortless long-distance comfort.

Every 2026 CT4 includes a robust list of driver assistance features that monitor the road and help prevent collisions whenever possible. Lane Keep Assist with Lane Departure Warning and Lane Change Alert with Side Blind Zone Alert work together to keep you aware of vehicles on the highway that you may have missed and gently steer you away when you need it. Following Distance Indicator, Forward Collision Alert, and Automatic Emergency Braking similarly work in tandem, notifying you of possible hazards and braking automatically if collision is imminent. These are but a few standard systems, while available enhancements like HD Surround Vision with Surround Vision Recorder, Front and Rear Park Assist, and a Head-Up Display instill extra confidence throughout Sacramento and beyond.
