20 MPG combined won’t win any fuel economy awards, but the 2020 Cadillac XT5 AWD with the 3.6L V6 isn’t trying to break hypermiling records. This vehicle is designed for confident all-weather capability, premium interior appointments, and effortless power for merging and passing. Fuel efficiency plays a role, but it’s often secondary to the driving experience. Imagine suburban professionals and empty-nesters who want a comfortable ride and a touch of luxury over squeezing every last mile from a gallon.

City and highway performance

The EPA estimates the 2020 Cadillac XT5 AWD at 18 MPG in the city and 25 MPG on the highway. The city rating reflects the XT5’s weight and the demands of stop-and-go driving, where the V6 works harder to move the nearly 4,300-pound SUV. The highway figure is more respectable, showcasing the engine’s ability to cruise efficiently once it’s up to speed. The nine-speed automatic transmission helps here, allowing the engine to operate at lower RPMs at higher speeds. However, the standard all-wheel-drive system adds weight and drivetrain friction, contributing to a slightly lower fuel economy compared to the front-wheel-drive version.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for this specific configuration of the 2020 Cadillac XT5 is $2,200. This figure is based on driving 15,000 miles per year and using the national average fuel prices at the time of calculation. Your actual fuel costs may vary depending on your driving habits, the type of fuel you use, and fluctuations in fuel prices. Luxury vehicles often prefer, if not require, premium fuel, which also increases the cost. Use this figure as a benchmark, not a guarantee.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world MPG often differs based on driving style, traffic conditions, and even tire pressure. Drivers with a heavier foot or those who frequently encounter stop-and-go traffic will likely see figures closer to the city rating, perhaps even slightly below it. Conversely, drivers who primarily use the XT5 for highway cruising and prioritize gentle acceleration might achieve numbers closer to, or even slightly above, the EPA’s 25 MPG highway estimate.

Regularly servicing your car, keeping your tire pressure at the correct PSI and not hauling unnecessary cargo weight, will also impact your real-world fuel economy.

How it compares

In the luxury SUV market, the 2020 Cadillac XT5’s fuel economy is generally on par with its rivals equipped with similar powertrains and all-wheel drive. The Acura RDX SH-AWD with its 2.0L turbo engine typically averages around 23 MPG combined. The BMW X3 xDrive30i, also using a turbocharged 2.0L engine, achieves a similar rating. A Mercedes-Benz GLC 300 4Matic, with their turbocharged 2.0L engine, hovers around 24 MPG combined.

Choosing a model with a smaller engine size, or opting for a hybrid like the Lexus RX 450h (around 30 MPG combined), is the easiest way to significantly improve fuel economy within this segment. Review all Cadillac fuel economy data to see if other vehicles interest you.

Tips to maximize efficiency

The 3.6L V6 under the hood of the XT5 is a smooth and responsive engine, but it also rewards a gentle touch. Avoid aggressive acceleration and hard braking, which can quickly decrease fuel economy. Anticipate traffic flow and maintain a steady speed whenever possible.

The nine-speed automatic transmission is designed to keep the engine in its most efficient operating range. Let it do its job by avoiding the temptation to manually shift gears unless necessary. In normal driving conditions, the transmission’s programming is optimized for less gas.

Ensure your tires are properly inflated to the recommended pressure, which can be found on the driver’s side doorjamb. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy. Check tire pressure regularly, especially during temperature changes.

Minimize the use of accessories like air conditioning and heated seats, as they place an additional load on the engine. Use these features only when necessary to maintain comfort in the vehicle. and ensure regular engine maintenance, such as oil changes, to help fuel economy.

Consider a different trim of the XT5. Examine the XT5 MPG across all years to see if a different drive type or trim will provide the fuel economy that you are seeking.
