26 MPG combined is a perfectly acceptable figure for the 2023 Lexus ES 350, especially considering this car: a supremely comfortable, effortlessly smooth luxury sedan powered by a naturally aspirated V6. This isn’t a hybrid, nor does it pretend to be. The ES 350 buyer prioritizes refinement and a proven powertrain over outright efficiency, likely swayed by Lexus’ reputation for bulletproof reliability and a quiet driving experience. They’re willing to trade a few MPG for the immediate, lag-free response of a traditional engine, coupled with a luxurious cabin and a plush ride.

City and highway performance

The EPA estimates the 2023 Lexus ES 350 achieves 22 MPG in city driving and 32 MPG on the highway. The spread between these numbers reveals where the ES 350 performs best. The 32 MPG highway figure is respectable for a V6-powered sedan of this size, reflecting the effectiveness of its eight-speed automatic transmission (S8) in optimizing fuel consumption at cruising speeds. In stop-and-go city traffic, however, the larger engine uses more gas, resulting in the lower 22 MPG rating. Drivers who frequently navigate congested urban environments should be mindful of this difference.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2023 Lexus ES 350 is $1,700. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use (the ES 350 only requires regular unleaded), and where you live, as fuel prices can fluctuate considerably from state to state. But this figure provides a useful benchmark for comparing the ES 350’s running costs to those of other vehicles in its class.

Real-world expectations

While the EPA estimates provide a standardized measure, real-world fuel economy can change based on individual driving styles and conditions. Aggressive acceleration, frequent hard braking, and consistently exceeding speed limits will all negatively impact your MPG. By employing smooth driving techniques, anticipating traffic flow, and adhering to posted speed limits, you can achieve figures closer to, or even exceeding, the EPA estimates. Many owners report averaging around 28 MPG in mixed driving conditions, showing that the 26 MPG combined rating is a realistic expectation for careful drivers. See ES MPG across all years.

How it compares

The Lexus ES 350’s fuel economy positions it competitively within the mid-size luxury sedan segment, though some competitors offer more efficient alternatives. For example, the Acura TLX, when equipped with its standard 2.0L turbocharged engine, achieves a combined EPA rating of 25 MPG, slightly behind the ES 350. The BMW 530i, with its 2.0L turbocharged four-cylinder, manages 27 MPG combined. The ES 350 has a smoother, more refined driving experience that some buyers value more than a marginal gain in fuel efficiency. The hybrid ES 300h is more frugal, at an impressive 44 MPG combined, and has a different driving character. Those chasing ultimate fuel economy within the Lexus family should review all Lexus fuel economy data.

Tips to maximize efficiency

Gentle acceleration is key to optimizing fuel economy in the ES 350. Avoid abrupt starts and try to maintain a steady pace. The V6 engine delivers plenty of power, and using it carefully will translate to fuel savings over time.

Proper tire inflation plays a critical role in fuel efficiency. Check your tire pressure regularly and inflate them to the recommended settings, which can be found on the sticker inside the driver’s side doorjamb. Underinflated tires create more rolling resistance, which reduces MPG.

Minimize idling whenever possible. If you anticipate being stopped for more than a minute or two, it’s more fuel-efficient to turn off the engine. Modern engines are designed to restart quickly and reliably, and the fuel saved by avoiding unnecessary idling can add up over the long run.

Regular maintenance is essential for optimal fuel economy. Ensure that your ES 350 receives scheduled oil changes, air filter replacements, and spark plug maintenance according to the manufacturer’s recommendations. A well-maintained engine runs more efficiently.
