The 2020 Lexus LX 570 gets 14 MPG combined. This vehicle isn’t purchased for its fuel efficiency. It’s a body-on-frame SUV, a status symbol, and a capable off-roader whose owners prioritize space, prestige, and reliability over trips to the gas station. Understanding this is key to understanding the LX 570’s appeal.

City and highway performance

The EPA estimates the LX 570’s city fuel economy at 12 MPG. Stop-and-go traffic, the vehicle’s weight, and the naturally aspirated 5.7L V8 engine all contribute to this figure. Highway driving fares slightly better, achieving 16 MPG according to the EPA. Even on the open road, the LX 570’s aerodynamics and full-time four-wheel-drive system keep fuel consumption high. The difference between city and highway MPG is small, so sustained high-speed cruising doesn’t offer a significant efficiency advantage.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2020 Lexus LX 570 at $4,150. This is based on driving 15,000 miles per year and using national average fuel prices. Factors that determine this annual fuel cost can change rapidly, but $4,150 is a measure of how expensive it is to fuel the LX 570. This number will likely be even higher for owners who drive more or find themselves consistently paying above-average fuel prices.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy can vary based on driving habits, terrain, and vehicle maintenance. Aggressive acceleration, frequent off-roading, and neglecting routine maintenance can all negatively impact fuel consumption. Gentle driving, proper tire inflation, and timely servicing can help to achieve figures closer to the EPA estimates. Understanding your own driving style and its impact on fuel consumption is critical for managing expectations with the LX 570. Owners are generally not hypermiling in this vehicle; the LX 570 is designed for long distance comfort and not prioritizing fuel consumption.

How it compares

The LX 570’s fuel economy is lower than many of its competitors among large luxury SUVs. The Land Rover Range Rover (specifically the P360 trim) manages around 19 MPG combined. Even the V8-powered Cadillac Escalade achieves approximately 17 MPG combined. The Infiniti QX80, another large SUV, is rated at 15 MPG combined. These comparisons highlight the LX 570’s relative inefficiency, a factor that some buyers may overlook given the Lexus’s reputation for reliability and strong construction, elements that contribute to its appeal and justify its positioning relative to all Lexus fuel economy data.

Tips to maximize efficiency

The LX 570 isn’t known for its fuel economy, but owners can take steps to minimize fuel consumption, even if modestly. Start by ensuring your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate them to the manufacturer’s recommended levels.

Avoid aggressive acceleration and braking. Sudden bursts of speed and hard stops will use more fuel than smooth and gradual driving. Anticipate traffic flow and maintain a steady speed to reduce unnecessary fuel consumption. Looking at LX MPG across all years can inform how your specific model compares within the LX family.

Minimize idling time. Idling wastes fuel, especially in a large-displacement engine like the LX 570’s. If you anticipate being stationary for more than a minute, turn off the engine. Modern vehicles restart quickly and efficiently, making this a practical way to conserve fuel.

Keep up with regular maintenance. Routine maintenance, such as oil changes, air filter replacements, and spark plug replacements, ensures that the engine is running at its optimal efficiency. A well-maintained engine burns fuel more efficiently than one that is neglected.

Lighten the load. Carrying unnecessary weight in your vehicle reduces fuel economy. Remove any items you don’t need from the cargo area. The less weight the engine has to move, the less fuel it will consume.
