2020 Cadillac XT5 vs. 2020 Cadillac XT6: What’s the Difference?

  • Cadillac now has three crossovers, two of which — the XT5 and the XT6 — are closely related
  • The Cadillac XT5 bowed for 2019, while the XT6 arrived for 2020
  • The XT5 seats five and the XT6 can accommodate up to seven

Over the course of just two years, Cadillac went from a car-heavy lineup to one loaded with crossovers and SUVs. Its XT4, XT5, and XT6 models share a lot more than just the first two letters of their names.

The XT5 was first on the scene, and it was initially called the Cadillac SRX. A 2017 remake saw the rename to XT5 plus big upgrades inside, outside and underneath. For 2020, the XT5 spawned the XT6, which is largely the same vehicle underneath, but the length stretches the better part of a foot farther and comes with three rows of seats.

Let’s take a look some more differences between the 2020 Cadillac XT5 and the 2020 Cadillac XT6.

2020 Cadillac XT5 vs. 2020 Cadillac XT6 exterior


At first glance, the two crossovers share some cues but appear quite different. The XT5 was recently updated with a mesh-looking grille, and it’s flanked by vertical headlights that are echoed with a similar design at the rear. The crossover’s rakish profile includes a roofline that slopes rearward from the passenger compartment into the cargo area and a big rearmost roof pillar that accentuates the sporty effect. See the 2020 Cadillac XT5 models for sale near you

By contrast, the XT6 has a similar grille surrounded by narrow, small headlights. Tall LED running lamps are perched at the corners of the front bumper. From the side, the XT6’s additional length — about 8 inches longer than the XT5 — is obvious, especially in its more conventional SUV-like roofline. At the rear, the XT6 uses taillights shaped similarly to those on the XT5, though the bigger Caddy’s are tinted in traditional red rather than the clear lenses of the XT5. See the 2020 Cadillac XT6 models for sale near you

The two crossovers are less distinguishable inside. Both make use of an 8-inch touchscreen that takes center stage on the dash. Identical climate control panels sit below, and most audio and infotainment functions are handled by two knobs and a handful of buttons located on the center console next to the cupholders. The XT5’s steering wheel is loaded with big buttons, while those on the larger XT6’s wheel appear better integrated.

Cadillac offers a wide array of interior hues for both, though the XT5 has a slightly wider palette of available leather and leatherette shades depending on the trim level.

The smaller, lighter XT5 comes standard with a turbocharged 4-cylinder and it offers a more powerful and smoother V6 as an option. That V6 is the only powerplant available on the XT6, which makes sense given the larger SUV’s heavier curb weight. Predictably, the XT6 is also less fuel-efficient, since its V6 is tasked with moving around more vehicle.

Both crossovers come standard with front-wheel drive and offer all-wheel drive as a $2,000 option. The crossovers’ AWD system can be switched into FWD mode to save fuel, though drivers will need to remember to reactivate the AWD system for slippery conditions.

  • 2.0-liter turbocharged inline-four rated at 237 horsepower, 258 lb-ft of torque; 21 miles per gallon in the city and 28 mpg on the highway (FWD)
  • 3.6-liter V6 rated at 310 hp, 271 lb-ft of torque; 18 mpg city/26 mpg hwy (FWD)

Both the XT5 and the XT6 show their close relation when it comes to safety and technology features. The two crossovers come standard with a basic automatic emergency braking system as well as parking sensors, lane-departure warnings, and a system that can help center the crossovers in their lane. Optional features include an upgraded automatic emergency braking system that can see farther ahead and apply the brakes earlier as well as adaptive cruise control, a head-up display, and a 360-degree camera system.

An 8-in touchscreen handles most infotainment and audio functions. The screen is bright and responsive, though it’s on the smaller side compared to those of similarly priced luxury crossovers. Additionally, a control knob, volume knob and several buttons on the center console provide secondary control and may also provide a more natural position for some drivers.

The XT6’s standard third-row seats offer seating for two additional passengers, though it’s best for children or smaller adults. The seats are power-folding in higher-specification models. Front-row and second-row space and comfort are nearly identical between the XT5 and the XT6.

2020 Cadillac XT5 vs. 2020 Cadillac XT6 pricing


The base XT5 Luxury trim level starts at $45,090, while the Premium Luxury that serves as the gateway to far more options and features runs $49,790 to start. The XT6 bypasses the Luxury trim and starts as Premium Luxury for $53,690, which means the XT6 is just shy of $4,000 more than the XT5 when it’s similarly equipped.

2020 Cadillac XT5 vs. 2020 Cadillac XT6 conclusion


The XT5 and XT6 may present a conundrum for some shoppers given their similarities. The third-row seats on the XT6 should be considered occasional-use, though the longer body increases cargo volume by nearly 50 percent over the XT5. If space is your priority, go for the XT6. If not, the XT5 delivers similar refinement, features and even styling for thousands less than its big brother. Find a Cadillac XT5 for sale or Find a Cadillac XT6 for sale
