25 MPG combined for the 2025 Lexus ES 350 F Sport with its 3.5-liter V6 is a pragmatic concession rather than a compromise for its target demographic. This isn’t a vehicle whose primary mission is to achieve hypermiling records; it’s a front-wheel-drive luxury sedan engineered for impeccable refinement, quiet comfort, and effortless power delivery. The F Sport designation adds a layer of visual aggression and a hint more dynamic intent, appealing to those who appreciate Lexus’s unwavering quality but desire a touch more verve in their daily commute. Those who choose the naturally aspirated V6 over the more efficient four-cylinder hybrid (which significantly boosts fuel economy) do so because they prioritize the smooth, linear acceleration and the time-tested reliability of a potent six-cylinder engine. They understand that this comes with a modest dip in fuel efficiency. The 25 MPG is a respectable figure for a car of this size and capability, a number that quietly affirms its place as a luxury cruiser.

City and highway performance

Looking at the specifics, the ES 350 F Sport achieves 22 MPG in city driving and an admirable 31 MPG on the highway. The city figure, at 22 MPG, is perfectly reasonable given the car’s 3.5-liter V6 and its inherent preference for smooth, unhurried acceleration. This engine, paired with the slick-shifting S8 automatic transmission, avoids the constant engine restarts and low-speed thrashiness that can affect some smaller, turbocharged setups in urban environments. The ES instead delivers a composed experience, and the 22 MPG reflects this refined approach. On the open road, where the V6 can settle into its stride, the 31 MPG highway rating truly shines. This allows for long-distance cruising without frequent fuel stops, aligning perfectly with the ES’s role as an exceptional road trip companion. The engine quietly hums along at highway speeds, demonstrating its impressive efficiency when not constantly accelerating and decelerating.

Annual fuel cost

The EPA estimates an annual fuel cost of $1,750 for the 2025 Lexus ES 350 F Sport. This figure is calculated based on an average driving distance of 15,000 miles per year and prevailing national average fuel prices. For many owners, this estimated cost is readily absorbed into their overall automotive budget, particularly when considering the ES’s competitive purchase price and Lexus’s reputation for stellar long-term reliability and low maintenance costs. The $1,750 per year is a predictable expense, not an unexpected drain, for buyers who value the premium experience and inherent quality that the ES 350 F Sport delivers. It reflects a straightforward cost for the luxury, power, and comfort the vehicle provides, aligning with the expectations of luxury sedan owners.

Real-world expectations

In the real world, owners of the ES 350 F Sport can generally expect to meet or slightly exceed the EPA estimates, particularly on longer highway journeys where the V6 operates most efficiently. The S8 automatic transmission plays a crucial role here, expertly managing gear changes to keep the engine in its optimal efficiency range. Drivers who spend a significant portion of their time in stop-and-go city traffic might see figures closer to the 22 MPG city rating, but rarely significantly below it, unless their driving style involves consistently aggressive starts. The vehicle’s smooth power delivery naturally encourages a more relaxed driving pace, which in turn benefits fuel economy. The ES’s excellent refinement and quiet cabin mean that even at highway speeds, there’s little motivation to push the engine unnecessarily hard, contributing to consistent real-world efficiency that mirrors the EPA’s projections.

How it compares

When placed against its competitive set, the 2025 Lexus ES 350 F Sport holds its own, often prioritizing a distinct luxury experience over outright fuel economy dominance. Consider the Acura TLX A-Spec with its 2.0-liter turbo, which typically achieves around 25 MPG combined, identical to the Lexus but with a less refined four-cylinder engine note and different performance characteristics. The BMW 330i, with its 2.0-liter turbo-four, often hits 28 MPG combined, sacrificing engine displacement for efficiency, catering to a buyer prioritizing a sporty, compact execution. A more direct competitor, the Mercedes-Benz C300, also powered by a 2.0-liter turbo-four, generally hovers around 27 MPG combined. The ES 350’s buyer isn’t cross-shopping a pure performance sedan; they’re evaluating a spacious, comfortable front-wheel-drive luxury cruiser where the V6 smoothness and all Lexus fuel economy data are prioritized. For those individuals weighing the overall package, the slightly lower combined MPG of the ES 350 compared to its smaller-engined German rivals is an acceptable trade-off for its superior cabin space, renowned reliability, and the inherent character of its V6 engine. For buyers primarily concerned with the ultimate fuel savings within the ES lineup, the ES 300h hybrid, which achieves 44 MPG combined, is the obvious alternative, but its audience is distinct from the F Sport buyer who still craves that V6.

Tips to maximize efficiency

Maintaining gentle throttle inputs, especially from a stop, is crucial for preserving the ES 350 F Sport’s city MPG. The V6 delivers its power smoothly, making it easy to avoid sharp acceleration which unnecessarily burns fuel.

Anticipate traffic conditions and coast when possible, allowing the vehicle’s momentum to carry you. This reduces the frequency of hard braking and subsequent hard acceleration, both of which are detrimental to fuel economy.

Regular tire pressure checks are simple yet effective. Properly inflated tires reduce rolling resistance, ensuring the big sedan glides as efficiently as designed on the highway.

Use cruise control on the highway to maintain a consistent speed. The S8 transmission is excellent at optimizing gears, and a steady pace allows the V6 to operate in its most efficient band, contributing to that impressive 31 MPG.

Adhere to the manufacturer’s recommended maintenance schedule. A well-tuned engine, with clean air filters and fresh fluids, simply operates more efficiently than one that is neglected.
