21 MPG combined isn’t going to win any fuel efficiency awards, but for the 2023 Cadillac XT5 AWD with the 3.6L V6, it’s a reasonable compromise. This isn’t a hypermiling hybrid; it’s a luxury SUV designed for comfort, confident all-weather performance, and a certain level of prestige. Owners seeking the XT5 often prioritize a smooth ride, a well-appointed interior, and the Cadillac badge, fuel economy is often a secondary concern, balanced against the benefits the V6 and AWD system provide.

City and highway performance

The EPA estimates suggest 18 MPG in city driving and 25 MPG on the highway. The city figure reflects the realities of stop-and-go traffic, where the XT5’s weight and the demands of the 3.6L V6 extract their penalty. The highway estimate, however, is more respectable. The 9-speed automatic transmission helps optimize engine speed at cruising velocity, contributing to that 25 MPG rating. While not class-leading, this highway figure is adequate for comfortable long-distance travels, a typical use case for XT5 owners who might regularly drive between suburban homes and vacation properties.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2023 Cadillac XT5 AWD 3.6L is $2,100. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Keep in mind that your actual fuel costs can vary significantly depending on your driving habits, the type of fuel you use (premium fuel is recommended, though not required), and local fuel prices. Aggressive driving, prolonged idling, and consistently driving in city traffic will all increase your annual fuel expenditure.

Real-world expectations

While the EPA estimates offer a useful baseline, real-world fuel economy often deviates. Drivers who frequently engage the XT5’s all-wheel drive system, particularly in inclement weather or on unpaved roads, can expect to see a drop in observed MPG. Similarly, using the vehicle for towing, while possible, will negatively impact efficiency. Overall, while some drivers might achieve close to the EPA estimates, others, depending on driving style and conditions, could see average fuel economy closer to 19-20 MPG. Owners can explore XT5 MPG across all years to compare.

How it compares

The Cadillac XT5’s fuel economy positions it amidst a competitive landscape. The Lexus RX 350 AWD, a perennial rival, manages around 22 MPG combined, showcasing a slight edge in efficiency. The Acura MDX with SH-AWD achieves similar figures, around 21-22 MPG combined. The BMW X3 xDrive30i delivers comparable numbers as well, hovering around 24 MPG combined. The Audi Q5 45 TFSI quattro gets around 25 MPG combined, making it a slightly more efficient choice. For the typical XT5 buyer, these variations might not be deal-breakers. They recognize that the Cadillac offers a distinct blend of American luxury, styling, and features that outweigh a marginal difference in fuel consumption. See all Cadillac fuel economy data here.

Tips to maximize efficiency

Proper tire inflation is critical for maximizing fuel economy. Regularly check your tire pressure and inflate them to the recommended levels specified on the door jamb sticker. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel.

Avoid aggressive driving habits such as rapid acceleration and hard braking. Smooth and consistent driving not only improves fuel efficiency but also reduces wear and tear on your vehicle’s components. Anticipate traffic flow and maintain a steady pace whenever possible.

Minimize idling time. If you anticipate being stationary for more than a minute or two, turn off the engine. Excessive idling wastes fuel and contributes to emissions. The XT5 doesn’t have a standard auto start/stop system, so manually shutting off the engine is a more efficient approach.

Consider limiting AWD usage when conditions don’t require it. While the XT5’s AWD system primarily engages when needed, continuously driving in AWD mode can slightly decrease fuel economy. If you’re driving on dry pavement, the system may still send some power to the rear wheels. If available, explore driving modes that prioritize fuel efficiency when possible.
