2021 Cadillac XT4 MODEL OVERVIEW


  • Comfortable highway cruising
  • Intuitive infotainment system
  • Sharp, elegant styling


  • Unrefined engine and transmission
  • Forgettable driving dynamics
  • Cheap interior feel

The XT4 is Cadillac's smallest SUV, positioned below the XT5, XT6, and Escalade. It was introduced for the 2019 model year, and size-wise, the little Caddy is somewhere between the subcompact and compact luxury SUV segments. The XT4's closest competitors are the Acura RDX, Infiniti QX50, and Volvo XC40.

What's New

  • Power liftgate now standard
  • Side mirror turn signal indicators standard on Premium Luxury and Sport trims
  • Leather seating now optional on base Luxury trim
  • Driver Awareness package now optional on Luxury trim

What We Think

Even with minor improvements for 2020 and 2021, the smallest of Cadillac's crossover options is still a disappointment. Styling is sharp, but interior design and material quality are lacking. Aside from the easy-to-use infotainment system, the cabin is dominated by plentiful hard plastic, and even the optional leather upholstery looks and feels cheap. It can be loud inside, too, and limited outward visibility makes rear seating feel cramped even if the measurements say otherwise.

The XT4's sole powertrain option is coarse and grainy, making it feel out of place in a luxury car. At least there's a strong surge of torque on boost. Steering is responsive, but navigating the XT4 around a bend exposes excessive body roll. This car is best experienced cruising on the highway, where its stable ride and comfortable front seats shine. That said, its competitors offer those same strengths with superior dynamics, better interior quality, and more refined mechanics.

Performance and Fuel Economy

The XT4 only has one powertrain option: a 2.0-liter turbo-four and nine-speed automatic combination with FWD or optional AWD. The four-pot develops 237 hp and 258 lb-ft of torque that, in our testing, took 7.5 seconds to accelerate to 60 mph. Fuel economy measures 22-24/29-30 mpg city/highway with FWD variants carrying a slight advantage.


The XT4 earns a five-star overall safety rating from the NHTSA, with four-star frontal crash and rollover scores. Automatic emergency braking and forward collision warning are standard on the base model. Stepping up to a Premium Luxury or Sport trim adds rear cross-traffic alert, blind-spot monitoring, front and rear parking sensors, adaptive cruise control, and lane keep assist.

Cargo Space and Interior Room

The XT4 exists as something of a 'tweener vehicle, positioned on the larger end of subcompacts and the smaller side of the compact segment. It offers seating for five with 44.1 inches of legroom up front and 39.5 inches in the back row; that latter number means you'll have more space in the rear of the Cadillac than you would in an Acura RDX, Infiniti QX50, or Volvo XC40. With 22.5 cubic feet of cargo volume behind the rear seat, the XT4 boasts more than the subcompact Volvo (20.7 cubes) but less than the compact Acura and Infiniti which both offer 31.1 cubic feet.


Regardless of trim, every XT4 features an 8.0-inch touchscreen infotainment system that is primarily operated via a rotary dial between the front seats. Apple CarPlay and Android Auto support are standard on all models, and integrated navigation is optional. Higher trims offer a larger 8.0-inch instrument cluster display plus a digital rearview mirror, wireless charging pad, 360-degree camera system, and a head-up display. Seven-speaker audio is standard, and audiophiles can opt for a 13-speaker Bose system.
