23 MPG combined is an understandable, if unexciting, figure for the 2022 Cadillac XT6 AWD with the 2.0L turbocharged four-cylinder engine. This configuration targets buyers who prioritize Cadillac’s luxury and styling, and the XT6’s three rows of seating but are willing to sacrifice some fuel efficiency compared to the front-wheel-drive model or competitors with hybridized powertrains. It’s a trade-off the typical XT6 buyer likely accepts, recognizing the vehicle’s mission as a comfortable and capable family hauler, not an economy champion.

City and highway performance

The EPA estimates the 2022 Cadillac XT6 AWD 2.0L achieves 21 MPG in the city and 26 MPG on the highway. These figures reflect the realities of driving a vehicle of this size and weight. City driving, with its frequent stops and starts, taxes fuel economy. The 2.0L turbo needs to work a bit to get the XT6 moving from a standstill, especially with the added weight of the all-wheel-drive system. The highway number, however, demonstrates that the XT6 can achieve reasonable efficiency when cruising at a steady speed. The nine-speed automatic transmission helps in this regard, keeping the engine in its most efficient range at higher speeds. However, aggressive passing maneuvers will rapidly diminish highway MPG.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2022 Cadillac XT6 AWD 2.0L will be $2,500. This figure is based on driving 15,000 miles per year and using national average fuel prices. This number provides a reasonable benchmark for budgeting, although individual fuel costs will vary based on driving habits, local fuel prices, and the specific type of gasoline used. The $2,500 figure represents a significant expense for some car buyers, and is a key factor in understanding the overall cost of ownership for an XT6.

Real-world expectations

While the EPA estimates provide a standardized baseline, real-world fuel economy can vary significantly. Factors such as driving style, traffic conditions, weather, and even tire inflation can impact the MPG you actually see. Expect to achieve numbers close to the EPA estimates if you primarily drive conservatively and adhere to posted speed limits.

However, if you frequently engage in aggressive acceleration, spend a lot of time in stop-and-go traffic, or often carry heavy loads, your fuel economy will likely be lower. The all-wheel drive system, while beneficial for traction, also adds weight and increases drivetrain losses, which impacts fuel consumption.

How it compares

Compared to other three-row luxury SUVs, the 2022 Cadillac XT6 AWD 2.0L occupies the middle ground in terms of fuel economy. The Acura MDX, equipped with its standard V6 and SH-AWD, achieves a slightly lower 21 MPG combined. The turbocharged four-cylinder Volvo XC90 B5 AWD boasts 25 MPG combined, outperforming the XT6 while offering similar levels of luxury and practicality. The Lincoln Aviator, a close competitor, with its standard twin-turbo V6, comes in significantly lower, at 20 MPG combined with AWD.

Potential XT6 buyers might also cross-shop the Lexus RX 350L, which returns 22 MPG combined with AWD. These comparisons are important because they highlight the compromises in this segment. Some prioritize power and performance, even at the expense of fuel economy, while others focus on maximizing efficiency without sacrificing too much luxury or space. The XT6 aims for a balance, but leans slightly toward the more luxurious end of the spectrum, understanding your priorities is critical before committing to to this vehicle.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The 2.0L turbo responds well to a gentle foot, and gradually building speed minimizes fuel consumption. Anticipate traffic flow and maintain a steady speed whenever possible; this reduces the need for sudden bursts of acceleration that quickly deplete fuel.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel efficiency. Check your tire pressure regularly and maintain the recommended levels listed on the tire placard, typically found on the driver’s side doorjamb.

Minimize idling time. Letting the engine idle for extended periods, such as when waiting in a parking lot, wastes fuel. If you anticipate being stationary for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, and restarting consumes less fuel than idling.

Reduce aerodynamic drag. Remove any unnecessary items from the roof rack or cargo carrier, as these increase wind resistance and lower fuel economy. Even driving with the windows open at higher speeds can negatively impact fuel efficiency, so use the climate control system when appropriate.
