The 2018 Lexus LX 570 gets 15 MPG combined. Owners who choose this reliable vehicle aren’t prioritizing lower fuel costs. Instead, this figure reflects the price of capability, opulent features, and the confidence of driving a well-known SUV. It’s not about maximizing miles per gallon, it’s about demanding off-road performance and Lexus refinement.

City and highway performance

The EPA’s combined rating breaks down to 13 MPG in the city and 18 MPG on the highway. The city figure isn’t just about stop-and-go driving, it’s about the LX 570’s weight, which is over 6,000 pounds, fighting its own inertia at every stop. The highway number offers a little improvement, but maintaining that 18 MPG requires a light foot; rapid acceleration will decrease your fuel consumption. The 5.7L V8 is powerful and thirsty.

Annual fuel cost

The EPA estimates the 2018 Lexus LX 570 will have an annual fuel cost of $3,850, based on driving 15,000 miles per year and using national average fuel prices. Potential owners should consider this carefully. The LX 570 is a significant investment that exceeds the initial purchase price. Budgeting for this annual expense is critical, and changes in fuel prices could raise this figure. Individual driving habits will influence the actual amount spent on fuel.

Real-world expectations

Don’t expect to match the brochure numbers. Drivers often report numbers lower than the EPA estimates, often around 12-14 MPG in mixed driving. This difference comes from aggressive driving, frequent towing, four-wheel drive, and the weight of aftermarket accessories. If you plan on using the LX 570 for off-roading, hauling cargo, or navigating rough terrain, expect even lower fuel economy. Owners often accept this as the cost for the vehicle’s capabilities.

How it compares

Few direct competitors offer the same luxury and off-road capability as the LX 570. The Land Rover Range Rover, another luxurious off-roader, achieves a slightly better 18 MPG combined with its supercharged V6. The Mercedes-Benz GLS 450 manages around 20 MPG combined with its turbocharged inline-6. However, neither of these vehicles mirror the Toyota dependability that underpins the LX 570. The Cadillac Escalade, with its 6.2L V8, is closer to the LX 570’s fuel consumption, at around 17 MPG combined, though its off-road abilities aren’t as strong. This decision isn’t just based on MPGs; it’s about choosing the right vehicle for a specific purpose, and the LX 570 is built for those who demand performance.

Tips to maximize efficiency

Don’t constantly accelerate quickly. The LX 570’s V8 delivers power, but using it often will use fuel fast. Accelerate gently and anticipate traffic flow.

Ensure your tires are properly inflated and consider using low rolling resistance tires when you replace them. Tire pressure greatly affects fuel economy, especially given the LX 570’s weight. Low rolling resistance tires can reduce fuel consumption without compromising safety.

Reduce unnecessary weight inside the vehicle. Carrying heavy cargo adds strain to the engine and reduces fuel efficiency. Remove unnecessary items and don’t use the LX 570 as storage.

Avoid using four-wheel drive unless you need it. Operating in 4WD on dry pavement puts stress on the drivetrain and increases fuel consumption. Leave it in 2WD unless you encounter slippery conditions or venture off-road.

Maintain the vehicle based on the schedule. A well-maintained engine runs efficiently. Regular oil changes, air filter replacements, and spark plug maintenance will ensure the 5.7L V8 runs at its best, increasing fuel mileage.
