Owners of the 2024 Cadillac XT5 with its front-wheel-drive configuration and strong 3.6L V6 engine can expect 21 MPG combined. This figure isn’t going to win any awards for lower fuel costs, but it accurately reflects the trade-off Cadillac’s target demographic makes; they get power, luxury, and a comfortable ride, and in return, they don’t get leading-edge fuel efficiency. People who choose this specific XT5 aren’t hyper-focused on squeezing every last mile from a gallon. They value the smooth and responsive performance of the V6 and the relaxed cruising experience it provides on longer trips.

City and highway performance

The EPA estimates the 2024 Cadillac XT5 FWD at 19 MPG in the city and 26 MPG on the highway. The city figure reflects the engine’s need to work harder during stop-and-go driving, especially given the vehicle’s weight and the engine’s 310 horsepower output.

The highway figure, however, is more respectable. The 9-speed automatic transmission allows the engine to settle into a more efficient range at cruising speeds, contributing to the more favorable highway rating. Regular highway travelers will appreciate both the fuel economy and the quiet, composed ride, making long journeys less taxing.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2024 Cadillac XT5 FWD is estimated at $2,100. This figure is based on driving 15,000 miles per year and using the national average fuel price at the time of calculation. Individual fuel costs will vary based on driving habits and regional fuel prices.

This $2,100 figure provides a standardized benchmark for comparing the XT5’s running costs against other vehicles in its class.

Real-world expectations

While the EPA provides valuable estimations, real-world mileage can often deviate. Aggressive driving, frequent short trips, and prolonged idling all negatively impact fuel economy. Consistent highway driving at higher speeds might yield slightly lower results than the EPA’s 26 MPG estimate. Drivers who prioritize smooth acceleration, anticipate traffic, and maintain consistent speeds can likely achieve figures close to the EPA’s estimates, even exceeding the 21 MPG combined rating under ideal conditions. Refer to XT5 MPG across all years for real world trends from drivers.

How it compares

The Cadillac XT5’s fuel economy positions it mid-pack within its competitive set. The Lexus RX 350, another common comparison, achieves a slightly better 25 MPG combined. However, opting for the RX’s all-wheel-drive system nudges the MPG down to a similar level to the XT5. Acura’s MDX, while offering more space as a larger three-row SUV, typically lands around 19-22 MPG combined, making it similar to the XT5 given its size.

On the other hand, a BMW X3 xDrive30i offers a slightly better combined MPG of 25, but with a possible trade-off in ride comfort, depending on configuration. The slightly diminished fuel economy of the XT5 relative to these competitors is a cost many find acceptable to maintain the V6 engine’s smooth power delivery and the uniquely Cadillac driving experience.

Tips to maximize efficiency

The 3.6L V6 is responsive, so be mindful of hard acceleration, particularly from a standstill. Gently increasing speed allows the engine to operate more efficiently, minimizing fuel consumption. The XT5’s 9-speed automatic transmission is designed to shift smoothly and efficiently; letting it do its job without aggressive inputs will help maximize fuel economy.

Regularly check tire pressure. Under-inflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Maintaining the recommended tire pressure, found on the driver’s side door jamb, is a simple way to improve fuel efficiency.

Limit idling time. The XT5 consumes fuel even when stationary with the engine running, like all gasoline vehicles. Avoid prolonged idling, especially in situations like waiting in parking lots or drive-thrus. Turning off the engine and restarting it is more efficient than idling for extended periods.

Reduce unnecessary weight. Excess cargo in the trunk or on the roof rack increases the vehicle’s overall weight, impacting fuel economy. Remove any items that aren’t essential for your regular driving, especially heavier items, to improve efficiency.

Consider using cruise control on the highway. By maintaining a consistent speed, cruise control helps the engine operate more efficiently, reducing fuel consumption. Be mindful of traffic conditions and adjust speed as needed for safety.
