How many miles per gallon does a 2015 LX570 get?
In brief, the 2015 LX 570 averages about 15 miles per gallon combined, roughly 13 mpg in city driving and 18 mpg on the highway.
The 2015 Lexus LX 570 is a large, 5.7-liter V8 SUV designed for power and capability, not just efficiency. With standard all-wheel drive and a heavy curb weight, its official fuel-economy figures reflect a baseline rather than a typical suburban commute. Real-world mileage depends on driving style, terrain, climate control use, and maintenance.
Engine and drivetrain basics
Powertrain details
The LX 570 uses a 5.7-liter V8 engine paired with an eight-speed automatic transmission and standard full-time four-wheel drive. This setup delivers strong towing and off-road capability, but it also places 1-ton-plus weight and drivetrain losses on fuel economy.
Weight and aerodynamics
With a substantial weight and a boxier SUV silhouette, the LX 570 isn’t optimized for low drag. These factors contribute to lower efficiency at highway speeds compared with lighter, more aerodynamic crossovers.
EPA fuel economy figures
Official government estimates provide a baseline for comparison across model years and configurations. For the 2015 LX 570, the EPA ratings reflect its standard AWD setup and 5.7-liter V8.
Before we list the numbers, note that EPA figures are published as city, highway, and a combined figure derived from testing under standardized conditions.
- City: 13 mpg
- Highway: 18 mpg
- Combined: 15 mpg
These figures serve as a baseline; real-world results typically vary based on how the vehicle is driven, road conditions, and environmental factors.
Real-world performance factors
Several variables influence actual fuel economy beyond the EPA numbers for the LX 570.
- Vehicle weight and payload: carrying passengers and cargo increases energy use.
- Terrain and climate: hilly roads and active climate control reduce efficiency.
- Driving style: aggressive acceleration and high-speed cruising lower MPG.
- Maintenance and condition: clean air filters, spark plugs, and proper tire pressure help preserve efficiency.
- Tire state and gearing: underinflated tires and non-original or wide tires add rolling resistance.
In practice, owners often report mpg in the mid-teens, with values around 12–16 mpg in mixed city and highway use depending on conditions.
Tips to maximize mpg
Implementing fuel-saving habits and keeping the LX 570 in good condition can help squeeze more efficiency from every mile.
- Keep tires inflated to the recommended pressure and use the correct size tires.
- Limit heavy cargo and remove roof racks when not in use to reduce aerodynamic drag.
- Drive smoothly: gradual acceleration, steady cruising speeds, and minimizing quick stops.
- Use cruise control on highways to maintain steady speeds and fuel use.
- Schedule regular maintenance: air filters, spark plugs, and oil changes as recommended by Lexus.
- Avoid prolonged idling and unnecessary auxiliary loads like running A/C excessively in stop-and-go traffic.
Following these practices can help achieve closer to the EPA combined figure under typical conditions, though the LX 570’s size and powertrain inherently cap its efficiency compared with smaller SUVs.
Summary
The 2015 Lexus LX 570 generally delivers about 15 miles per gallon combined (around 13 mpg in the city and 18 mpg on the highway). Real-world results vary with weight, terrain, and driving style. The vehicle trades fuel economy for V8 power and off-road capability, but thoughtful driving habits and proper maintenance can help maximize efficiency within its performance envelope.
What is the best year of the Lexus LX 570?
The best year for a Lexus LX 570 depends on your priorities, but the 2013-2015 model years are often cited for a good balance of reliability and features, while 2016-2021 models offer the newer eight-speed transmission and enhanced safety features. If you prioritize the most modern features and safety systems, a later model is ideal, whereas earlier models may be less expensive and have a more robust feel to some enthusiasts. All LX 570s are known for durability and longevity, especially if well-maintained.
2013-2015
- Pros: Considered by some as a sweet spot for reliability, with a 6-speed transmission that some may find simpler, and a comfortable ride. The styling was revised in 2013, introducing the spindle grille.
- Cons: Lacks the 8-speed transmission and the latest advanced safety features of later models.
2016-2017
- Pros: Introduced the 8-speed automatic transmission, improving fuel economy slightly. The 2017 model year made Lexus Safety System Plus standard, adding features like forward-collision mitigation and adaptive cruise control.
- Cons: The 8-speed transmission may be more complex than the older 6-speed.
2018-2021
- Pros: These models are essentially the same as the 2016-2017 in terms of powertrain and major features, offering the benefits of the 8-speed transmission and standard safety tech. They are the final years before a redesign.
- Cons: Potentially higher price points compared to earlier models.
Overall considerations
- Reliability: All LX 570s (from 2008-2021) are based on the highly reliable Toyota Land Cruiser platform and are known for their extreme durability and longevity with proper maintenance, even at high mileage.
- Maintenance: Regardless of the year, regular maintenance, particularly the 30,000-mile service and ensuring the hydraulic suspension fluid is flushed, is crucial for long-term reliability.
- Technology: Features like Apple CarPlay were not standard, so you may need to budget for an aftermarket upgrade to get that functionality.
