15 MPG combined. Those three words, attached to the 2016 Lexus LX 570, won’t scare away its target demographic. This isn’t a vehicle purchased for its frugality. It’s a fortress on wheels, a statement of capability and luxury, and its owners prioritize those attributes far above saving a few dollars at the pump.

City and highway performance

The EPA estimates the 2016 Lexus LX 570 achieves 13 MPG in the city and 18 MPG on the highway. That city figure, in particular, reflects the LX’s weight and the demands placed on its 5.7L V8 engine when navigating stop-and-go traffic. The highway number, while still not impressive, is more palatable; at least the engine operates in a more consistent range where it doesn’t have to constantly accelerate from a standstill. These figures are derived from a standardized testing procedure, meaning that in the real world, results will vary widely depending on driving style, terrain, and load.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Lexus LX 570 to be $3,850. This figure is calculated based on driving 15,000 miles per year and using national average fuel prices. For owners who put significantly more miles on their LX, or those who live in areas with higher fuel costs, the real annual expenditure will be substantially higher. For those who tend to drive less and own the vehicle more for its stature and all-weather capability than for racking up highway miles, the number may be a little lower. Regardless, anyone considering an LX should budget accordingly.

Real-world expectations

Consistently hitting the EPA estimates in the real world will be a challenge for most LX 570 drivers. The vehicle’s weight, combined with the naturally aspirated V8, means a heavy right foot will be punished severely. Expect to see numbers closer to the low end of the range in mixed driving. Towing, off-roading, or frequently hauling heavy loads will further decrease fuel economy. Drivers who prioritize smooth acceleration and consistent highway speeds can potentially get closer to the 18 MPG highway figure.

How it compares

The LX 570 doesn’t exist in a vacuum. Competitors like the Land Rover Range Rover, particularly the supercharged V8 models, offer similar levels of luxury and off-road prowess, but at the expense of similar fuel economy, around 16 MPG combined is what you might expect in a Land Rover. Another competitor, the Cadillac Escalade, offers slightly better MPG around 17MPG, but with a different character and driving experience. Those seeking to stay inside the Toyota/Lexus family can explore all Lexus fuel economy data and may consider the GX 460 or the new TX. Ultimately, the LX buyer is rarely swayed by slight MPG differences; they are drawn to the LX’s specific blend of ruggedness, reliability, and Lexus refinement.

Tips to maximize efficiency

The LX 570 responds well to a gentle touch. Avoiding rapid acceleration and hard braking will significantly improve fuel economy. Anticipate traffic conditions and maintain a consistent speed whenever possible. Using cruise control on the highway can help prevent unnecessary fluctuations in speed and improve your MPG.

Ensure your tires are properly inflated. Low tire pressure increases rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate them to the recommended specifications listed on the driver’s side doorjamb.

Reduce unnecessary weight. Every extra pound carried in the vehicle contributes to lower fuel economy. Remove any items from the cargo area that are not essential, as well as roof racks and cargo carriers when they are not in use. Consider how often you actually need all three rows of seats up.

Regular maintenance is key. A well-maintained engine operates more efficiently. Follow the recommended maintenance schedule for oil changes, air filter replacements, and spark plug inspections. Address any mechanical issues promptly to prevent them from negatively impacting fuel economy.

Be mindful of idling. Letting the engine idle for extended periods consumes fuel without moving the vehicle. If you anticipate being stopped for more than a minute or two, turn off the engine. This is especially important in city driving, where idling is more common.
