: Good vehicle. Decent, but not quite the best. Often affordable, but lacking key features found in vehicles of the same class.

What's New

The 2021 Cadillac CT4 enters its second year as the luxury band's compact sedan offering. Standard equipment now includes SiriusXM 360 L satellite radio and wireless Apple CarPlay and Android Auto compatibility. The Teen Driver system gains a Buckle to Drive feature that delays starting up to 20 seconds when the driver's belt isn't fastened.

The optional Technology Package adds a 12-inch HD gauge cluster. The mid-level Premium Luxury trim gets a new Diamond Sky design package. Cadillac's SuperCruise semi-autonomous driving system is available on the AT4 for the first time.

Choosing Your Cadillac CT4

The CT4 continues in four trim levels: Luxury, Premium Luxury, Sport, and V-Series. Pricing starts at $34,390 including destination and reaches $45,890 for the V-Series before options.

Engine Choices

A turbocharged 2.0-liter four-cylinder engine is standard on the Luxury, Premium Luxury, and Sport. A 2.7-liter turbo four-cylinder is available on the Premium Luxury for $3,900. A high-output version of the 2.7-liter is exclusive to the V-Series.

Engine TypeHorsepowerTorqueFuel Economy (Combined)
2.0L Turbo 4-Cylinder237 hp258 lb-ft27 mpg
2.7L Turbo 4-Cylinder310 hp350 lb-ft25 mpg
2.7L Turbo 4-Cylinder325 hp380 lb-ft25 mpg

The 2.0-liter runs with an eight-speed automatic transmission, while the 2.7-liter gets a 10-speed automatic.

All models start out with rear-wheel drive. All-wheel drive costs $2,000 with the base engine, and $3,200 with the 2.7-liter available on the Premium Luxury. Adding AWD to the V-Series costs just $500.

Passenger and Cargo Capacity

The Cadillac CT4 can seat five, but its interior dimensions suggest that four will be more comfortable. The trunk is on the small side at 10.7 cubic feet.

Safety Features

The entry-level Luxury comes with forward collision warning with pedestrian detection and automatic braking. While that's a key safety technology, it's the only one available.

The other trims provide rear parking sensors and access to three option groups. The Driver Awareness Plus Package ($800) includes blind-spot monitoring with rear cross-traffic alert, active lane keeping assist, a following distance indicator, and automatic high beams. Buyers can also add a Driver Assistance Package ($900) with adaptive cruise control, rear automatic emergency braking, and radar-enhanced front automatic braking. The $1,350 Technology Package throws in a 12-inch configurable gauge cluster, a head-up display, and a cabin air ionizer.

Finally, the SuperCruise semi-autonomous driving system ($3,100) is available on Premium Luxury models equipped with the 2.7-liter engine and every V-Series. All three of the preceding package must be in place to add SuperCruise.


The standard infotainment system for all trims offers an 8-inch touchscreen, eight speakers, SiriusXM 360 L and HD radio, wi-fi capability, and wireless Apple CarPlay and Android Auto capability.

The Sun and Sound Package ($2,200) for the Luxury trim includes a 14-speaker Bose surround-sound system, navigation, wireless device charging, and a sunroof. Elsewhere in the lineup, this bundle is called the Navigation and Bose Premium Audio Package because the sunroof isn't included – it's a $1,050 standalone option. The package costs $1,400 on the Premium Luxury and Sport, and just $500 on the V-Series.

CarsDirect Tip

The 2021 Cadillac CT4 Luxury trim carries a very attractive price, but not enough equipment to compete in this league. The Premium Luxury covers all the bases, and transforms into a strong performer with the optional engine. Since the Sport's upgrades are cosmetic, buyers looking for real thrills must advance to the V-Series.
