21 MPG combined won’t win any awards for fuel efficiency, but it accurately reflects what buyers of the 2019 Cadillac XT5 AWD 3.6L are willing to accept. This isn’t a vehicle purchased to save on gas; it’s a luxury crossover bought for its style, comfort, and all-weather capability. The 3.6L V6 provides ample power, and the all-wheel-drive system delivers confident traction in challenging conditions. For the target demographic, the fuel consumption is an accepted cost of entry into this segment.

City and highway performance

The EPA estimates the XT5 3.6L AWD at 18 MPG in the city and 25 MPG on the highway. The city figure reflects the realities of stop-and-go driving, where the engine spends more time at lower speeds and idling. The highway number is more palatable, as the 8-speed automatic transmission allows the engine to cruise at lower RPMs, maximizing fuel efficiency. However, even on the highway, aggressive acceleration and higher speeds will quickly reduce that 25 MPG figure. The all-wheel-drive system adds weight and complexity and is a significant selling point for buyers in colder climates, further tempering concerns about optimal fuel economy.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2019 Cadillac XT5 AWD 3.6L is $2,100. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. It also assumes the use of regular unleaded gasoline at the national average price. Individual costs will vary based on driving habits, local fuel prices, and the actual number of miles driven each year. A driver who primarily uses the XT5 for short city trips will likely spend far more than $2,100 on fuel annually, while someone who mainly uses it for highway cruising may spend less.

Real-world expectations

While the EPA provides a standardized testing method, real-world fuel economy can vary significantly. Factors like driving style, traffic conditions, and even tire pressure can impact MPG. Drivers who accelerate quickly will undoubtedly see lower numbers than those who drive conservatively. Most XT5 owners will likely see figures somewhere between the EPA’s city and highway estimates, depending on their typical driving. Staying on top of maintenance like air filter replacements and proper tire inflation can also help maintain optimal fuel economy.

How it compares

The 2019 Cadillac XT5’s fuel economy places it in the middle of its competitive set. The Lexus RX 350 AWD, a perennial rival, achieves a slightly better 22 MPG combined. The Acura RDX SH-AWD comes in at 23 MPG combined thanks to its turbocharged 2.0L engine. The Mercedes-Benz GLC 300 4MATIC is rated at 24 MPG combined. The BMW X3 xDrive30i nets a combined 24 MPG too. These small differences may not be a deciding factor for most buyers; style, features, and brand perception often play a more significant role in the purchasing decision. Potential buyers can review all Cadillac fuel economy data to compare the XT5 to other Cadillac models too. You can also find XT5 MPG across all years.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The 3.6L V6 in the XT5 provides plenty of power, making it tempting to accelerate quickly. However, smooth and gradual acceleration will significantly improve fuel economy, especially in city driving. Anticipate traffic flow and avoid sudden stops whenever possible.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate your tires to the recommended pressure listed on the sticker inside the driver’s side door. A simple tire pressure gauge can save you money at the gas pump.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long highway trips. However, avoid using cruise control in hilly terrain because the transmission may downshift frequently, negating any potential fuel savings.

Reduce unnecessary weight. Excess weight puts a strain on the engine, reducing fuel economy. Remove any unnecessary items from the trunk and back seat. Even small amounts of extra weight can add up and impact MPG over time.

Consider using synthetic oil. Synthetic motor oil can reduce friction within the engine, potentially leading to a slight improvement in fuel economy. While the gains may be small, synthetic oil also offers superior protection and can extend oil change intervals.
