The 2019 Lexus LX 570 gets 15 MPG combined. This isn’t an economy car. It’s a body-on-frame, full-size luxury SUV engineered for serious off-road capability and unwavering reliability, attributes that prioritize ruggedness over fuel sipping. The LX 570 buyer wants a supremely comfortable, go-anywhere vehicle with the gravitas of the Lexus name, and they understand that this comes with a price at the pump. Fuel efficiency is simply not a primary concern for this demographic.

City and highway performance

The EPA estimates the 2019 Lexus LX 570 achieves 13 MPG in the city and 18 MPG on the highway. These figures reflect the inherent compromises of a large displacement engine powering a heavy vehicle. The 5.7L V8, while producing ample power for both on-road cruising and tackling challenging terrain, is simply not designed for optimal fuel conservation. The eight-speed automatic transmission contributes to smoother shifts and slightly improved highway efficiency compared to older models, but it cannot fully mitigate the engine’s thirst. Stop-and-go city driving will yield the lowest MPG figures, while steady highway cruising might approach, but rarely exceed, the EPA’s 18 MPG estimate.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,850 for the 2019 Lexus LX 570. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s crucial to understand that this is just an estimate. Your actual fuel costs will vary depending on your driving habits, local fuel prices, and the type of driving you do. Someone who primarily uses the LX 570 for short city trips is likely to spend considerably more than $3,850 annually, while someone who does mostly highway driving might spend somewhat less. This annual fuel cost should be a key consideration for potential buyers. For a broader perspective, view all Lexus fuel economy data.

Real-world expectations

Do not expect to consistently match the EPA estimates in real-world driving conditions. Factors such as aggressive acceleration, frequent braking, carrying heavy loads, and using the four-wheel-drive system will all negatively impact fuel economy. The LX 570’s considerable weight and aerodynamic profile inherently limit its efficiency.

Drivers living in hilly or mountainous areas should also anticipate lower MPG numbers. While meticulous driving habits can help eke out slightly better fuel economy, the LX 570 is fundamentally a thirsty vehicle, and managing expectations is key to avoiding disappointment. Anyone considering buying should review LX MPG across all years to get a realistic picture.

How it compares

Compared to its competitors, the LX 570’s fuel economy is generally on the lower end. The Land Rover Range Rover, depending on the engine configuration, achieves combined MPG figures ranging from 16 to 19 MPG. The Cadillac Escalade, with its 6.2L V8, posts a similar combined MPG of around 17. Even the Infiniti QX80, another large luxury SUV, manages a slightly better 16 MPG combined. These differences, while seemingly small, can translate to significant savings at the pump over the lifespan of the vehicle. However, buyers drawn to the LX 570 often prioritize its legendary reliability and off-road prowess over marginal fuel economy gains offered by competitors.

Tips to maximize efficiency

While the LX 570 will never be a fuel-sipping champion, there are steps you can take to optimize its efficiency. Avoid aggressive acceleration and hard braking, as these habits significantly increase fuel consumption. Maintain a steady speed on the highway, and anticipate traffic conditions to minimize unnecessary speed fluctuations.

Ensure your tires are properly inflated to the recommended pressure. Underinflated tires increase rolling resistance, which reduces fuel economy. Regularly check your tire pressure and adjust it as needed, especially with fluctuations in temperature.

Minimize idling time whenever possible. Letting the engine idle for extended periods consumes fuel without covering any distance. If you’re going to be stopped for more than a minute or two, it’s best to turn off the engine.

Reduce the weight you’re carrying in the vehicle. Unnecessary cargo adds to the overall weight, which reduces fuel economy. Remove any items you don’t need to carry on a regular basis, especially heavy objects.

Service your vehicle according to the manufacturer’s recommendations. Regular maintenance, such as oil changes and air filter replacements, ensures that the engine is running efficiently. A well-maintained engine consumes less fuel and produces fewer emissions.
