Most 2016 Lexus LX 570 owners report real-world fuel economy between 12 to 14 mpg in the city and 17 to 19 mpg on the highway, with combined driving averaging 14 to 16 mpg. The EPA officially rates this model at 13 mpg city, 18 mpg highway, and 15 mpg combined, but actual owner data shows slightly lower city performance.
How Real-World MPG Compares to EPA Estimates
| Driving Type | EPA Rating | Typical Owner Results | Difference |
|---|---|---|---|
| City | 13 mpg | 12.1 mpg | -0.9 mpg |
| Highway | 18 mpg | 17.6 mpg | -0.4 mpg |
| Combined | 15 mpg | 14.3 mpg | -0.7 mpg |
One owner reported 15 mpg during mixed city and highway driving between Detroit and Toronto. Another owner who drives mostly city got about 12.5 mpg combined with a heavy foot. Highway driving with cruise control tends to come closer to EPA estimates.
What Affects Your Fuel Economy
Several factors impact how many miles per gallon you'll actually get. Driving habits matter most: aggressive acceleration and frequent braking hurt efficiency. Heavy modifications like aftermarket bumpers and winches reduce fuel economy. Taller tires and winter blend fuel also pull down your numbers. Vehicle maintenance keeps your engine running efficiently.
The LX 570 uses a 5.7-liter V8 engine with 383 horsepower. It's one of the least efficient vehicles in its luxury SUV class. For comparison, the Cadillac Escalade with a larger 6.2-liter engine gets 15 to 21 mpg, while the Range Rover Supercharged achieves 13 to 18 mpg.
Take Action
Track your fuel consumption for a few fill-ups to establish your baseline. Use cruise control on highways to boost highway mileage toward EPA estimates. Keep your tires properly inflated and stay on top of maintenance. Avoid carrying unnecessary weight. Remove roof racks when not in use. These habits won't transform the LX 570 into a fuel sipper, but they help you get closer to those highway numbers.
