The 2021 Cadillac XT4 FWD, with its 2.0L turbocharged four-cylinder engine, gets a combined fuel economy rating of 26 MPG. This positions it competitively in the compact luxury SUV segment, but it’s not the leader. Instead, this MPG reflects a balance by Cadillac: efficiency, style, and a comfortable driving experience.

City and highway performance

The EPA breaks down the XT4’s fuel efficiency to 24 MPG in the city and 30 MPG on the highway. The city rating shows the engine’s power for urban driving. Stop-and-go traffic hurts fuel economy, but the XT4’s nine-speed automatic transmission helps reduce that. The highway figure is more appealing, suggesting a comfortable and economical experience for road trips. Many XT4 owners are empty-nesters or couples who use their vehicle for commuting and weekend trips, so the highway MPG is important.

Annual fuel cost

The EPA says the annual fuel cost for the 2021 Cadillac XT4 FWD is $2,250. This is based on driving 15,000 miles per year and using national average fuel prices. An owner’s actual fuel cost will vary depending on their driving, the fuel they use (premium is recommended, but not required), and where they live. The $2,250 estimate is a benchmark when budgeting or comparing running costs.

Real-world expectations

While the EPA estimates offer a standard for comparison, real-world fuel economy often differs. A driver who frequently uses the XT4’s Sport mode or accelerates quickly will likely see lower MPG. Someone who primarily drives on the highway gently can exceed the EPA’s 30 MPG rating. Due to the XT4’s small fuel tank, drivers might refuel frequently on long trips, even with decent MPG figures.

How it compares

The luxury compact SUV segment has many competitors, each with different fuel efficiencies. The Lexus NX 300h hybrid gets 31 MPG combined, making it a clear winner for less gas use. The NX’s driving isn’t as engaging as the XT4’s, which some buyers care about. The Acura RDX gets 24 MPG combined, slightly below the XT4’s. The BMW X1, known for its sporty handling, gets around 28 MPG combined. These differences can lead to savings over the vehicle’s life. Potential buyers should weigh the XT4’s fuel economy against its other features, like its Cadillac styling and interior, to see if it fits their priorities. For those interested in comparing all Cadillac fuel economy data it is possible to make an easy and informed decision. Further comparisons can be made when considering the XT4 MPG across all years.

Tips to Maximize Efficiency

Keep a steady speed on the highway to get good fuel economy in the XT4. The turbocharged engine works best when not constantly accelerating. Using cruise control on long drives can improve your MPG a lot.

Make sure your tires are inflated to the right pressure. Underinflated tires create rolling resistance, which lowers fuel efficiency. Check your tire pressure often, especially when the temperature changes.

Don’t idle unnecessarily. The XT4 burns fuel even when stopped with the engine on. If you’ll be stopped for more than a minute, turn off the engine.

Use accessories like air conditioning less, especially on short trips. These put a load on the engine, decreasing fuel economy. Open windows when possible instead of using the A/C.

Regular maintenance is important for optimal fuel efficiency. Have your XT4 serviced routinely, including oil changes, air filter replacements, and spark plug maintenance, as recommended. A maintained vehicle works better and delivers better fuel economy.
