The 2021 Cadillac XT6 luxury midsize 3-row SUV/crossover is modern, capable, arguably attractive, relatively affordable, and comes with many great features. That’s the good news. The bad news is that XT6 is not exceptional, which is a bit of a disappointment considering Cadillac had a lot of time to check out the competition before launching it last year.
It shares a platform with the Buick Enclave, Chevrolet Traverse, and GMC Acadia. And that’s fine. These vehicles all have plenty of passenger space. The XT6 represents the highest level. And even though its range only consists of three versions, each one has its own particular appeal.
What’s New for 2021?
A new Luxury trim becomes the XT6’s entry-level model, bringing the total number of trims to three. Wireless Apple CarPlay/Android Auto smartphone integration is fitted as standard throughout the range. A new design of 20-inch alloy wheel is available for the top Sport trim. Dark Moon Blue Metallic, Wilder, and Infrared Tintcoat are fresh exterior paintwork choices. See the 2021 Cadillac XT6 models for sale near you

In entry-level Luxury trim, the 2021 XT6 has a turbocharged 2.0-liter 4-cylinder engine making 237 horsepower and 258 lb-ft of torque. This engine is linked to a 9-speed automatic transmission. Front-wheel-drive (FWD) is the standard setup, all-wheel drive (AWD) is optional.
The Environmental Protection Agency (EPA) estimates fuel consumption at 21 miles per gallon in the city, 27 mpg on the highway, and 23 mpg in combined driving (FWD) or 21 mpg city/26 mpg highway/23 mpg combined (AWD).
Premium Luxury and Sport versions have a naturally aspirated 3.6-liter V6 engine developing 310 horsepower and 271 lb-ft of torque. Once again, a 9-speed automatic transmission is in the picture.
Premium Luxury has front-wheel drive as standard and all-wheel drive with a single-clutch rear axle as an option. Sport trim has a model-specific torque-vectoring all-wheel-drive system with an electronic twin-clutch rear axle as standard.
EPA fuel consumption estimates for this engine are 19 mpg city/26 mpg hwy/21 mpg combined (FWD) or 18 mpg city/25 mpg highway/21 mpg combined.
Towing capacity is 1,000 pounds with the 4-cylinder engine, 4,000 pounds with the V6.

Behind the Wheel
Some other luxury midsize crossovers also kick off their ranges with turbocharged 4-cylinder engines, like the Audi Q7 and Mercedes-Benz GLE 350. However, both of those examples are more powerful than the XT6’s and still don’t exactly set the tarmac alight. The XT6’s 3.6-liter V6 delivers decent power and the 9-speed automatic transmission does a good job of keeping the engine in the right rev range.
On dry public roads at speeds below 45 mph, it’s hard to tell the difference between the top two trims’ all-wheel-drive systems. Higher speeds and more challenging conditions like rain and snow give an edge to the Sport version.
Sport trim’s adaptive suspension delivers a stiffer ride than the Premium Luxury’s regular setup. Styling differences between these two trim levels and the contrasting driving experiences will be a matter of taste and budget, but the Sport would still be the enthusiast’s choice.
With either engine, the cabin is quiet, even under heavy throttle. The interior is more than pleasant and has some clever storage spots. There’s plenty of room in the second row for adults, and the third row is accessed easily by a one-handed flip of the second row.
The center console has an ingenious slot that houses a wireless device charger. A jog/shuttle rotary controller in the center console is for the infotainment system and the 8-in color touchscreen on the dash.
There are 12.6 cubic feet of luggage space behind the third row, not much compared with the competition. But folding down the second and third seating rows reveals a considerable 78.7 cubic feet of maximum cargo volume.

Questions You May Ask
How does the 2021 Cadillac XT6 compare with the Lincoln Aviator?
The Lincoln Aviator costs a bit more than the XT6 in Luxury trim, but it has more horsepower as standard. There’s also a plug-in hybrid model. However, the XT6 has a larger 3rd-row seat. Both vehicles offer similar levels of active and passive safety features, most as standard equipment.
Where is the 2021 Cadillac XT6 built?
At General Motors’ plant in Springhill, Tennessee.
Is there a V performance version of the XT6?
No. The closest the 2021 XT6 comes is the Sport trim, with a sport-tuned active suspension, quicker steering, and a torque-vectoring all-wheel-drive system for optimum cornering ability.
Although the Premium Luxury version is tempting, it’s approaching the price territories of more desirable alternatives. The Luxury trim is the most affordable, yet still has all the XT6 style. Find a Cadillac XT6 for sale
