19 MPG combined. That’s the number that often causes a double-take when discussing the 2016 Lexus LS 460 L. It’s not offensive for a large sedan with a strong V8, but it’s also a number that acknowledges this isn’t about squeezing every last mile from a gallon. The LS 460 L appeals to a specific buyer: someone who prioritizes a plush ride, a whisper-quiet cabin, and the unwavering reliability Lexus has built over decades. They may run a business, entertain clients in the back seat, or simply demand quiet comfort on longer journeys. For them, fuel economy is a secondary consideration, a necessary trade-off for the LS 460 L’s unique blend of attributes.
City and highway performance
The EPA estimates of 16 MPG in the city and 24 MPG on the highway reflect the LS 460 L’s personality. Stop-and-go traffic demands a lot from the 4.6L V8, forcing it to repeatedly accelerate its considerable mass. This takes a toll on efficiency. On the open road, however, the eight-speed automatic transmission allows the engine to settle into a relaxed cruise. The relatively low RPMs at highway speeds contribute to a quieter cabin and improved fuel consumption. However, even at speed, overcoming the inherent aerodynamic challenges of a large luxury sedan necessitates a consistent level of engine power, and thus, fuel use.
Annual fuel cost
The EPA estimates that the annual fuel cost for the 2016 Lexus LS 460 L is $3,050. This figure is calculated based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. The calculation also incorporates the national average fuel price at the time of estimation. Keep in mind that this annual fuel cost is simply an estimate.
Your actual expenses will vary depending on your driving habits, the type of fuel you use, and changes in gas prices.
Real-world expectations
While the EPA provides a standardized benchmark, real-world fuel economy often deviates. Aggressive driving, frequent short trips, and prolonged idling can all negatively impact MPG. Conversely, careful throttle control, anticipatory braking, and prioritizing highway miles can help you achieve figures closer to the EPA’s ratings. A well-maintained vehicle is also crucial, ensure the tires are properly inflated, the engine is regularly serviced, and the air filter is clean. These factors will all have an effect on fuel efficiency.
How it compares
Compared to rivals, the 2016 Lexus LS 460 L’s fuel economy places it predictably in the middle of the pack. A similarly equipped BMW 750i from the same year, boasting a turbocharged V8, managed around 17 MPG city and 25 MPG highway, albeit with greater overall performance. The Mercedes-Benz S550, another V8-powered competitor, hovered around similar numbers.
Meanwhile, something like a Genesis G90 with the optional V8 offered comparable luxury at potentially a slightly lower fuel cost of approximately 16/24 MPG city/highway. These comparisons matter to the LS 460 L buyer because although fuel economy isn’t important, it’s still a factor weighed against the Lexus’s reputation for reliability and lower maintenance costs.

Tips to maximize efficiency
Drive smoothly and avoid aggressive acceleration. The LS 460 L’s V8 provides ample power, but pressing hard on the accelerator pedal will significantly reduce fuel economy. Smooth, gradual acceleration allows the engine and transmission to operate more efficiently, saving fuel without sacrificing meaningful progress.
Maintain a steady speed on the highway. Using cruise control when appropriate helps minimize speed variations, which consequently minimizes fuel consumption. The LS 460 L is most efficient when cruising at a consistent speed, using its high gear ratios and relaxed engine RPMs.
Keep your tires properly inflated. Low tire pressure increases rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressure regularly and inflate them to the recommended level, which is typically found on a sticker inside the driver’s side doorjamb. Properly inflated tires also improve handling and extend tire life.
Minimize idling time. Idling consumes fuel without covering any distance. If you’re waiting for someone or stopped for an extended period, turn off the engine. Modern engines start easily and quickly, so restarting is generally more fuel-efficient than idling for more than a minute. Lexus has considerable all Lexus fuel economy data for you to compare.
Consider using Top Tier gasoline. Top Tier gasoline contains additives that help keep your engine clean, which can improve fuel economy over time. While the LS 460 L doesn’t strictly require premium fuel, using higher-quality gasoline may contribute to better engine performance in the long run.
