What is the fuel consumption of the 2018 Lexus LX 570?
The 2018 Lexus LX 570's EPA-rated fuel economy is 13 mpg city, 18 mpg highway, and 15 mpg combined. In metric terms that's roughly 18.1 L/100 km city, 13.0 L/100 km highway, and 15.7 L/100 km combined.
This article explains what those numbers mean, how they apply to daily driving, and how real-world mileage can vary for this full-size luxury SUV powered by a 5.7-liter V8.
Official EPA estimates
These figures reflect the U.S. Environmental Protection Agency's published ratings for the 2018 LX 570 with standard drivetrain. Variations in wheel size, tires, and equipment can affect the numbers.
EPA estimates for the 2018 LX 570 are as follows:
- City: 13 mpg
- Highway: 18 mpg
- Combined: 15 mpg
Note: Real-world mileage often falls short of the EPA figures, with urban driving (stops and starts) typically producing lower results than highway cruising.
Real-world performance and factors
What drivers typically see
In everyday use, many LX 570 owners report real-world mileage generally in the mid-teens, commonly around 14–17 mpg depending on traffic, terrain, payload, and driving style. The weight of the vehicle, its large V8 engine, and luxury features all contribute to higher fuel consumption compared with mid-size SUVs.
Influencing factors
Several variables influence actual performance, including:
- Wheel size and tires (larger wheels can reduce economy slightly)
- All-wheel drive vs. rear-drive configurations
- Payload and towing load
- Terrain, elevation, and climate control usage
- Maintenance condition and fuel quality
Understanding these factors helps explain why real-world numbers can diverge from EPA estimates for the LX 570.
Practical tips to maximize efficiency
Even within a luxury SUV framework, small changes can yield incremental mpg gains. Consider the following guidance when driving or purchasing an LX 570.
- Keep tires inflated to the manufacturer’s recommended pressure for optimal rolling resistance.
- Schedule regular maintenance (air filters, spark plugs, oxygen sensors) to maintain engine efficiency.
- Avoid roof racks or heavy luggage when not needed, as roof drag increases fuel consumption.
- Use cruise control on highways and drive at steady speeds to minimize fuel use.
- Plan routes to reduce idling time and unnecessary stops.
Following these steps can help you extract better efficiency from the LX 570 without compromising its luxury and capability.
Summary
The 2018 Lexus LX 570 is a large, powerful luxury SUV with EPA ratings of 13 mpg city, 18 mpg highway, and 15 mpg combined. Real-world mileage typically lands in the mid-teens and is influenced by wheel size, load, driving style, and terrain. While not a fuel-efficient vehicle by modern standards, understanding the factors at play and applying practical driving habits can help maximize efficiency without sacrificing comfort and capability.
Is the 2018 Lexus LX 570 reliable?
Reliability. The 2018 Lexus LX 570 has a 4 years / 50,000 miles basic warranty and 2 recalls. RepairPal gives it a reliability rating of 4 out of 5, ranks it #6 out of 48 among Luxury Fullsize Cars. Below you'll find our owner reviews.
What is the fuel consumption of Lexus LX 570?
The guzzler consumes 16.7 L/100KM but compensates by providing sufficient power to accelerate well and travel off roads.
How many miles per gallon does the LX 570 get?
The Lexus LX 570's MPG is approximately 12 city / 18 highway / 14 combined for recent model years like 2020 and 2021, though it varies slightly by year and conditions. Older models, such as the 2017 and 2018 versions, have slightly different ratings but are also around 13 city / 18 highway / 15 combined. Real-world mileage can be lower, depending on driving habits and conditions.
EPA estimated MPG by model year
- 2021: 12 city / 16 highway / 14 combined
- 2020: 12 city / 16 highway / 14 combined
- 2019: 13 city / 18 highway (combined not specified but typically 15)
- 2018: 13 city / 18 highway / 15 combined
- 2017: 13 city / 18 highway / 15 combined
- 2014: 12 city / 17 highway / 14 combined
Important considerations
- Real-world vs. EPA: Actual mileage will vary. For example, a 2021 test saw an average of 13.6 mpg, and a 2017 trip netted 15 mpg, while other reports mention even lower figures in certain conditions.
- Engine: The LX 570 is equipped with a large 5.7L V8 engine, which contributes to its lower fuel economy.
How many miles per gallon does a 2018 Lexus LX 570 get?
13 mpg city and 18 mpg highway
The full-time four-wheel drive and six-speed automatic transmission are standard as well. As with the 460, the compromise between power and fuel economy is even bigger here as the 570 only gets 13 mpg city and 18 mpg highway.
