The 2016 Lexus LS 460 L AWD gets 18 MPG combined. If you’re shopping for maximum miles per gallon, you’re in the wrong showroom. This isn’t about squeezing every last drop from a gallon of premium fuel; it’s about experiencing unparalleled smoothness, quiet comfort, and unwavering reliability, hallmarks of the Lexus flagship. People who buy a long-wheelbase, all-wheel-drive LS understand this tradeoff. They prioritize a luxurious and insulated journey over hyper-efficiency.

City and highway performance

The LS 460 L AWD gets EPA estimates of 16 MPG in the city and 23 MPG on the highway. The city figure reflects stop-and-go traffic where the 4.6-liter V8 has to work to move the car’s weight. On the open road, the eight-speed automatic transmission helps keep the engine at an efficient RPM for cruising, contributing to the higher highway rating. Spirited acceleration will change these figures quickly, but the LS is more about effortless power than outright speed.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Lexus LS 460 L AWD at $3,200. This calculation is based on driving 15,000 miles per year and using the national average price of fuel at the time of testing. Your personal fuel costs will vary depending on your driving habits, local fuel prices, and the number of miles you actually drive each year. Driving aggressively and high fuel prices will increase that $3,200 figure.

Real-world expectations

The EPA provides a standardized baseline, and real-world fuel economy often differs. LS 460 L AWD owners often report figures that fluctuate around the EPA estimates, but often a little lower in combined driving. Aggressive driving, prolonged idling, and short trips can negatively impact fuel consumption. However, careful driving with steady acceleration and highway cruising can bring you closer to, or even slightly above, the EPA’s numbers.

How it compares

The 2016 Lexus LS 460 L AWD is in a segment with similar cars with similar, if not slightly better, fuel economy. The BMW 750i xDrive, for example, gets 19 MPG combined and has more horsepower. The all-wheel-drive Mercedes-Benz S550, with its turbocharged V8, also gets around 19 MPG combined. Even the Audi A8, praised for its efficiency, gets around 21 MPG. These small differences rarely sway a buyer in this class. Decision-making comes down to brand loyalty, preferred driving dynamics, and interior appointments. You can compare LS MPG across all years to see how this model compares.

Tips to maximize efficiency

Gentle acceleration is key. The LS 460 L’s V8 offers ample power, so there’s no need to stomp on the accelerator. Gradual increases in speed will minimize fuel consumption.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tires regularly and inflate them to the recommended pressure. This can make a noticeable difference.

Avoid excessive idling. Letting the engine run wastes fuel. If you’re stopped for more than a minute, turn off the engine to conserve fuel. Modern cars are designed to restart quickly and efficiently.

Use cruise control on the highway. Maintaining a consistent speed minimizes unnecessary acceleration and deceleration, which can improve fuel economy on long drives. Set your speed and let the car manage the throttle.

Lighten the load. Carrying unnecessary weight in the trunk or cabin reduces fuel economy. Remove any extra items that you don’t need regularly. The lighter the car, the less energy it takes to move.
