25 MPG combined isn’t going to win the 2024 Cadillac XT4 AWD any fuel efficiency awards, but it’s an acceptable number when you consider what this compact luxury crossover is trying to be: a stylish, comfortable, and capable urban vehicle with a premium badge. This isn’t a Prius competitor; it’s for buyers who value the elevated driving position, available all-wheel drive, and advanced design more than squeezing every last mile from a gallon of premium gasoline. They’re willing to trade a few MPG for the image and features Cadillac provides.

City and highway performance

The EPA estimates the 2024 Cadillac XT4 AWD will achieve 23 MPG in the city and 28 MPG on the highway. The city figure is where many owners will likely spend most of their time, navigating urban environments and stop-and-go traffic. The 28 MPG highway figure is fine for longer road trips, but it’s not a standout number in this segment. The 9-speed automatic transmission tries to keep the 2.0L turbocharged four-cylinder engine in its best range, but its priorities often lean towards responsiveness rather than outright fuel conservation. Cadillac understands that these buyers also prioritize driving experience.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2024 Cadillac XT4 AWD is $2,300. This figure is based on driving 15,000 miles per year and assumes current national average fuel prices for premium gasoline, which is the recommended fuel for optimal performance. Your individual fuel costs may vary depending on your driving habits, the type of driving you do (city vs. highway), and local fuel prices. This $2,300 estimate provides a useful benchmark for comparing the XT4’s operating costs to other vehicles in its class. To save money, you can also choose to purchase regular fuel, though XT4 performance is somewhat reduced in that case.

Real-world expectations

While the EPA estimates provide a standardized benchmark, real-world fuel economy can vary significantly. Aggressive driving, frequent short trips, and cold weather can all negatively impact fuel consumption. Careful driving, gentle acceleration, and consistent highway speeds may allow you to exceed the EPA estimates. Owners who live in hilly or mountainous areas should also expect lower fuel economy numbers overall.

The XT4’s all-wheel-drive system, while beneficial in inclement weather, also adds weight and parasitic loss, which further influences fuel efficiency. Be sure to monitor your average fuel economy via the infotainment system’s trip computer, and adjust driving habits accordingly.

How it compares

The Acura RDX SH-AWD, a key competitor to the XT4, manages 23 MPG combined. The BMW X1 xDrive28i achieves 28 MPG combined, a significant advantage. The Lexus NX 350h AWD hybrid boasts 39 MPG combined, making it a far more fuel-efficient choice for those prioritizing economy. The Audi Q3 quattro comes close to the XT4 with 25 MPG combined, but the Cadillac has a unique position with many buyers for its styling and brand cachet. The Volvo XC40 B5 AWD also lands at 26 MPG combined. For those cross-shopping, XT4 MPG across all years should be part of the decision-making.

Tips to maximize efficiency

Avoid aggressive acceleration. The XT4’s turbocharged engine delivers ample power, but using it frequently will decrease fuel economy. Gentle starts and smooth acceleration will help you get the most out of each gallon. Plan errands efficiently to minimize cold starts. Cold engines are less efficient than warm ones, so combining multiple errands into a single trip can save fuel.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended pressure listed on the driver’s side doorjamb. Proper tire inflation also improves handling and extends tire life.

Minimize idling. Idling for extended periods consumes fuel without covering any distance. If you’re stopped for more than a minute or two, turn off the engine. The exception is instances that require climate control or accessory power.

Use cruise control on the highway. Maintaining a consistent speed using cruise control can help improve fuel economy on long highway drives. Avoid sudden speed changes, which can waste fuel. The XT4’s adaptive cruise control makes this easier, although its sensors work best in clear weather.

Keep up with scheduled maintenance. Regular oil changes, air filter replacements, and other maintenance items can help ensure that your engine is running efficiently. Neglecting maintenance can lead to decreased fuel economy and other problems. Consider visiting all Cadillac fuel economy data for a broader perspective based on vehicle type.
