The 2022 Cadillac XT5 with the 3.6L V6 gets 21 MPG combined, a detail that may not be the primary concern for buyers. This Cadillac prioritizes a comfortable ride, elegant styling, and a respectable dose of power for effortless cruising. Fuel economy is a factor, but it’s secondary to the luxury experience and the V6 engine’s performance.

City and highway performance

The EPA estimates the front-wheel-drive, 3.6L V6-powered XT5 achieves 19 MPG in the city and 26 MPG on the highway. The city number reflects stop-and-go driving, where the larger engine consumes more fuel. However, the highway figure is competitive, demonstrating the engine’s capability to deliver acceptable mileage when cruising at steady speeds, thanks to its nine-speed automatic transmission, which helps keep the engine in its sweet spot for efficiency at higher speeds.

Annual fuel cost

Based on EPA estimates, the annual fuel cost for the 2022 Cadillac XT5 FWD 3.6L is $2,100. This calculation assumes 15,000 miles driven per year, with a mix of city and highway conditions, and national average fuel prices. Your actual fuel costs may vary based on your driving habits, the type of roads you frequent, and fluctuations in gasoline prices. The $2,100 figure provides a ballpark estimate to factor into the cost of ownership.

Real-world expectations

While the EPA provides standardized ratings, real-world fuel economy often differs. Aggressive acceleration, frequent short trips (where the engine doesn’t reach optimal operating temperature), and carrying heavy loads negatively impact fuel consumption. XT5 drivers who prioritize a spirited driving experience will likely see figures below the official estimates. Conversely, those who adopt a smooth driving style, minimize unnecessary idling, and adhere to posted speed limits may find their actual MPG closer to, or even slightly above, the EPA numbers. Checking owner forums and fuel log websites can provide further insights into what drivers are experiencing. You may find more XT5 MPG across all years, too.

How it compares

The Cadillac XT5’s fuel economy is typical for its class. Some competitors offer alternatives that use less gas. The Lexus RX 350 mirrors the XT5’s overall mission, but comes in at 23 MPG combined, a noticeable advantage.

The Acura RDX, with its turbocharged four-cylinder, boasts 24 MPG combined, appealing to those who want a luxury SUV with a bit more frugality. Then there’s the Lincoln Corsair, a domestic competitor, which achieves 25 MPG combined with its base engine. The all-wheel-drive versions of these competitors often see a slight dip in MPG, but for buyers who prioritize fuel savings, these alternatives are choices to consider. Keep in mind that when cross-shopping, looking at all Cadillac fuel economy data can show how the model compares to the entire brand lineup.

Tips to maximize efficiency

Take advantage of the Cadillac’s drive mode selector. The XT5 often includes a “Tour” or “Eco” mode that optimizes engine and transmission settings for improved fuel efficiency. Engaging this mode softens throttle response and encourages earlier upshifts, promoting a more relaxed and economical driving style. Experiment with the different drive modes to find the balance between performance and efficiency that best suits your needs.

Monitor your tire pressure regularly. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tires at least once a month and inflate them to the pressure recommended on the door jamb sticker. This simple maintenance task can have a significant impact on your fuel economy and also extends tire life.

Minimize idling time as much as possible. Idling consumes fuel without covering any distance. If you anticipate being stopped for more than a minute or two, turn off the engine. The restart is quick and efficient, saving fuel in the long run. Modern starters and battery systems are designed to handle frequent restarts without causing premature wear.

Practice smooth acceleration and braking. Avoid sudden bursts of speed and hard braking, as these actions waste fuel. Accelerate gradually and anticipate traffic flow to maintain a steady pace. Gently ease off the accelerator and allow the vehicle to coast when approaching stoplights or slowing down for traffic.

Consider using cruise control on long highway drives. Maintaining a consistent speed helps to optimize fuel efficiency. Cruise control minimizes unnecessary speed fluctuations, resulting in steadier fuel consumption. Just be sure to disengage cruise control when driving in heavy traffic or inclement weather conditions.
