The CT4 lineup begins with the Luxury trim, which establishes the model’s character with a 2.0L twin-scroll turbo engine, rear-wheel drive, and a composed chassis. It rides on 17” alloy wheels and delivers a clean, understated exterior matched to a well-appointed cabin focused on comfort and clarity.

Premium Luxury builds on that foundation with a more expressive presentation. Larger 18” wheels, LED ambient interior lighting, and leather seating surfaces elevate the atmosphere. This trim introduces advanced driver-assist technologies through its Driver Assist and Climate Packages and is the gateway to the available 2.7L dual-volute turbo engine for drivers seeking greater output.

Sport is the most visually assertive CT4. A performance-styled front fascia, black mesh grille, gloss black exterior accents, and Pearl Nickel 18” wheels distinguish it immediately. Inside, the Sport trim features heavily bolstered 18-way front seats, alloy pedals, and steering-wheel paddle shifters, reinforcing its driver-focused intent.

Standard motivation comes from a 2.0L twin-scroll turbocharged 4-cylinder producing 237 hp and 258 lbs.-ft. of torque, paired with an 8-speed automatic transmission. For Premium Luxury models, Cadillac offers a 2.7L dual-volute turbocharged engine generating 310 hp and 350 lbs.-ft. of torque, transforming the CT4 into a compact sedan with genuine straight-line authority.

Rear-wheel drive is standard, with all-wheel drive available for added confidence during Mid-Atlantic winters.

The CT4 balances athleticism and daily composure with carefully tuned suspension geometry and near-ideal weight distribution. Available Brembo® V Performance front brakes enhance stopping confidence, while the Driver Mode Selector allows drivers to tailor throttle response, steering feel, and transmission behavior.

The available AWD system adds traction without muting the car’s rear-drive character, making the CT4 equally capable on winding Maryland back roads and highway runs toward Baltimore or Washington, DC.

Inside, the CT4 emphasizes craftsmanship and intelligent ergonomics. Available 18-way power front seats with heat, ventilation, and lumbar massage create a first-class driving environment, particularly on longer trips. Premium trims add leather seating surfaces, textured aluminum trim, and subtle ambient lighting.

Passenger accommodations are thoughtfully proportioned for a compact sedan, while the trunk provides practical cargo space for daily errands or weekend travel. Optional Bose® 14-speaker surround sound transforms the cabin into an intimate concert hall.

An 8” HD infotainment display anchors the dashboard, complemented by an available 12” reconfigurable digital instrument cluster and a full-color Head-Up Display that projects key information directly into the driver’s line of sight. Wireless charging, Wi-Fi® hotspot capability, and available in-vehicle apps keep occupants connected.

For extended highway travel, available Super Cruise® hands-free driver assistance brings cutting-edge convenience to compatible roads.

The 2026 CT4 comes standard with Forward Collision Alert, Automatic Emergency Braking, Lane Keep Assist with Lane Departure Warning, and an HD Rear Vision Camera. Available technologies expand protection with HD Surround Vision, Adaptive Cruise Control, Reverse Automatic Braking, Rear Cross-Traffic Alert, and a Safety Alert Seat that communicates warnings through tactile feedback.

Together, these systems create a comprehensive safety net designed for modern driving demands without intruding on the experience behind the wheel.
