The 2024 Cadillac XT6 AWD models with the 2.0L turbocharged four-cylinder engine get 23 MPG combined. This isn’t the best in its class, but it’s acceptable. It’s simply what you can expect for those who need a comfortable and stylish three-row SUV with available all-wheel drive, but who may not be focusing on saving the most fuel.

City and highway performance

The EPA estimates the 2024 Cadillac XT6 AWD 2.0L achieves 21 MPG in city driving and 26 MPG on the highway. This difference is typical for vehicles with this engine and purpose.

The 21 MPG city figure reflects the frequent stops in urban commutes, where the engine is constantly accelerating from a standstill. On the open road, the XT6’s nine-speed automatic transmission helps keep the engine in its most efficient range, giving it the higher 26 MPG highway rating. Drivers who travel long distances regularly will appreciate that number, and may even exceed it with careful driving. But around town, expect to see numbers closer to (or even below) the EPA’s city estimate.

Annual fuel cost

The EPA says the annual fuel cost for the 2024 Cadillac XT6 AWD 2.0L is about $2,500. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will change depending on your driving habits, the type of fuel you use, and local gas prices.

If you mostly drive in the city or are aggressive with the accelerator pedal, you can expect to pay more than the EPA estimate. However, if you drive mostly on the highway and use fuel-efficient driving techniques, you may be able to save money on fuel. The XT6 typically calls for premium fuel, which will also increase your overall costs. You can find all Cadillac fuel economy data on this site.

Real-world expectations

The EPA’s estimates are a useful starting point, but real-world fuel economy can change a lot depending on driving conditions and habits. When driven carefully, the 2.0L turbo should deliver acceptable fuel economy. However, fuel economy will suffer if you frequently use the engine’s 258 lb-ft of torque. The XT6 AWD 2.0L isn’t a light vehicle, and the engine needs to work to move it quickly.

Owners who frequently carry passengers or cargo, or who drive in hilly areas, should also expect lower fuel economy. Those considering an XT6 may also want to check XT6 MPG across all years for more information.

How it compares

The 2024 Cadillac XT6 AWD 2.0L is in a competitive class of three-row luxury SUVs when it comes to fuel efficiency. The Acura MDX with SH-AWD gets an EPA-estimated 21 MPG combined, putting it in the same range. The Lexus RX 350L has Lexus’s reputation for reliability, and it gets around 22 MPG combined. The Volvo XC90 B5 AWD is rated at 25 MPG combined, giving it a slight edge in efficiency. Those numbers diminish when you compare the respective models’ base prices and available features. XT6 buyers are often looking for an American luxury experience at a competitive price and are willing to accept slightly lower MPG to get that.

Tips to maximize efficiency

Gentle acceleration and smooth braking are important for getting the best fuel economy in the XT6 AWD 2.0L. Avoid driving aggressively, like hard acceleration and sudden stops, because these actions use more fuel. Watch the traffic flow and maintain a steady speed when you can. The nine-speed automatic transmission is designed to keep the engine in its most efficient range, so let it do its job without unnecessary prodding.

Regular maintenance is key for the best fuel economy. Make sure your tires are properly inflated, because underinflated tires can increase rolling resistance and reduce MPG. Keep up with scheduled maintenance, such as oil changes and air filter replacements. A well-maintained engine will run more efficiently and use less gas.

Remove extra weight from your vehicle. Carrying extra cargo or equipment can hurt fuel economy. Remove any items that you don’t need and avoid using roof racks or cargo carriers unless you have to, because these accessories can increase aerodynamic drag.

Consider using cruise control on the highway. Cruise control helps keep a consistent speed, which can improve fuel economy on long drives.

Be careful on hilly terrain, because cruise control may cause the transmission to downshift frequently, reducing fuel efficiency. In these situations, it may be more efficient to manually control your speed.

Don’t let the engine idle longer than necessary. Idling uses fuel and increases emissions. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, so you won’t be wasting gas by turning it off and on. This is especially important in cities with frequent stops.
