The Cadillac CT4 is powered by a choice of turbocharged 4-cylinder engines sending power to either the rear-wheels or all-four wheels via an optional all-wheel drive system. The base engine displaces 2.0 liters and makes 237 horsepower and a stout 258 lb-ft of torque. Power is sent to the wheels via a standard 8-speed automatic transmission. Premium Luxury and V-Series models are available with a bigger 2.7L 4-cylinder which makes either 309 horsepower in Premium Luxury trim or 325 horsepower in V trim. Opting for the bigger engine also nets buyers a couple of extra gears as the only transmission choice with the bigger engine is a 10-speed automatic. An 8-inch touchscreen housed in the dashboard is well integrated with the various infotainment and technology systems. A leather-wrapped steering wheel with optional heating offers subtle metallic accents and sharp looking, integrated paddle shifters. Soft touchpoints and a general lack of hard plastics also help to heighten the appeal of the CT4 interior. The CT4 comes in four trims for 2021 including Luxury, Premium Luxury, Sport and V-Series. Standard features on the base CT4 Luxury trim include keyless entry, dual-zone automatic temperature control, a remote engine starter, 2 USB ports, wireless phone connectivity, 4GLTE Wi-Fi hotspot capability, SiriusXM satellite radio, voice activation for the 8-speaker sound system, OnStar turn by turn navigation, an auto-dimming rearview mirror with a built in garage door opener, 8-way power adjustable front seats and leatherette upholstery. Outside, the CT4 comes standard with automatic LED headlights, a rearview camera, automatic wipers, integrated, mirror mounted turn signals, chrome exhaust tips and 17-inch alloy wheels. The Premium Luxury and Sport Trims give buyers access to the bigger 2.7L engine as well as 18-inch wheels. Premium Luxury equipped cars also get leather seating surfaces available in a couple of different colors, while Sport equipped cars get blacked out exterior trim, a rear spoiler, transparent tail lamp lenses and sports seats. The CT4-V is immediately recognizable from the outside thanks to its unique grille and quad-exhaust tips. In addition to the extra power, the CT4-V gets magnetic adjustable dampers, which adjust suspension stiffness at the push of a button. Inside, the V-series gets a Bose premium sound system with 11-speakers. The Diamond Sky Special Edition Package offers up an exclusive exterior and interior finish with unique wheels, Brembo front brakes with blue calipers, alloy pedals and wood trim. The new Technology Package for 2021 adds a 12-inch digital configurable driver cluster with a head-up display. Now on offer for 2021 is the Driver Awareness Plus Package with Super Cruise. It comes with Lane Keep Assist and IntelliBeam with the new semi-autonomous driving system.
