The 2022 Cadillac XT6 with front-wheel drive and the 3.6L V6 engine gets 21 MPG combined. This seven-seater luxury crossover isn’t designed for fuel economy competitions. People buy it for the Cadillac badge, its spacious interior, and its comfortable ride. Fuel consumption is a cost of ownership, carefully considered but ultimately accepted.

City and highway performance

EPA estimates rate the XT6 at 19 MPG in the city and 26 MPG on the highway. The 19 MPG city rating is typical for a vehicle of this size and weight, due to stop-and-go driving. The 26 MPG highway suggests the nine-speed automatic transmission helps, but the 3.6L V6 works to move a significant amount of mass, even at cruising speed. Keep in mind these EPA estimates are achieved under controlled conditions, and aggressive driving will reduce these numbers.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2022 Cadillac XT6 FWD at $2,100. This assumes 15,000 miles of driving per year, a blend of city and highway miles, and the national average fuel price when calculated. Individual fuel costs will vary depending on local fuel prices, driving habits, and the proportion of city versus highway driving. Drivers who spend more time in congested urban areas will exceed this estimate, while those who primarily drive on the open highway may see a slightly lower annual cost. This $2,100 figure is a benchmark for comparing the XT6’s running costs against other vehicles.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy differs. Drivers can expect figures to fluctuate based on several factors. Aggressive acceleration and hard braking negatively impact fuel consumption, as does carrying heavy loads or towing. Properly maintained tires, regular servicing, and avoiding excessive idling all help achieve the EPA estimates.

The XT6’s trip computer provides real-time and average fuel economy data, allowing drivers to monitor their efficiency and adjust their driving habits. Most owners report numbers within 1-2 MPG of the EPA estimates, showing the official figures are representative of normal driving.

How it compares

The XT6’s fuel economy is in the middle of its class. The Acura MDX, in its front-wheel-drive configuration, gets 19 MPG city and 26 MPG highway, matching the XT6. The Lincoln Aviator, with its standard turbocharged engine, offers 18 MPG city and 26 MPG highway. The Volvo XC90 B5 manages 22 MPG combined, but the XC90 is more expensive and has a smaller engine. These comparisons are important because buyers often compare luxury SUVs, weighing fuel efficiency, performance, features, and price.

Shoppers seeking more less gas might consider the Lexus RX 350, which achieves 23 MPG combined, but it lacks the XT6’s third-row seating. For more information, review all Cadillac fuel economy data.

Tips to maximize efficiency

Smooth and steady acceleration helps fuel economy in the Cadillac XT6. Avoid abrupt starts and hard braking because they consume more fuel. Anticipate traffic flow and maintain a consistent speed.

Make sure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressure and inflate them to the recommended level, found on the sticker inside the driver’s side doorjamb. You can also research XT6 MPG across all years to see if there have been improvements.

Reduce unnecessary weight in the vehicle. Excess cargo adds load and decreases fuel economy. Remove items that are not regularly needed.

Minimize idling time. Idling consumes fuel. If you anticipate being stopped for more than a minute, turn off the engine. The XT6 does not have auto stop-start, so minimizing idling is more important.

Use cruise control on the highway to maintain a consistent speed, which can improve fuel economy. Avoid using cruise control in hilly terrain, as the vehicle may downshift frequently to maintain speed.
