The 2019 Lexus ES 300h 2.5L 4-cyl achieves 44 MPG combined, an impressive number considering it delivers traditional Lexus luxury, comfort, and quiet in a stylish, spacious sedan. This is a genuine Lexus, blending efficiency with the brand’s core values. Buyers seek a refined driving experience and a reputation for reliability, and the ES 300h delivers both without sacrificing fuel economy.

City and highway performance

The EPA numbers show remarkable consistency between city and highway driving. With 43 MPG in the city and 45 MPG on the highway, the ES 300h’s hybrid powertrain demonstrates its versatility. This is because the electric motor handles much of the low-speed propulsion in stop-and-go traffic. On the highway, the Atkinson-cycle 2.5L 4-cylinder engine takes over, aided by the electric motor to maintain efficiency during cruising and acceleration. The automatic (AV-S6) transmission further optimizes fuel consumption by selecting the most efficient gear for any given situation. Drivers who spend a lot of time in suburban environments, with a mix of city and highway driving, will likely see fuel economy very close to the official combined number.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Lexus ES 300h at $1,000. This figure is based on driving 15,000 miles per year, using national average fuel prices. This is a helpful standardized metric to compare running costs with other vehicles, though your personal fuel expenses may vary based on your driving habits and location.

Real-world expectations

While EPA estimates provide a standardized benchmark, real-world fuel economy can fluctuate depending on driving style, traffic conditions, and even weather. Because the ES 300h is a hybrid, it tends to perform closer to its EPA estimates than many non-hybrid vehicles. Aggressive acceleration and high-speed cruising will decrease fuel economy. Drivers who adopt a smoother, more deliberate driving style will likely see results very close to the official 44 MPG. Regular maintenance, including tire inflation and oil changes, also plays a role in maintaining optimal fuel efficiency.

How it compares

The ES 300h occupies a sweet spot in the luxury hybrid sedan market. The Acura TLX Hybrid (discontinued after 2015) could never match the ES 300h’s MPG. The Lincoln MKZ Hybrid, offered around the same time, achieved around 40 MPG combined, making the ES more appealing to those seeking maximum efficiency. Even within the Lexus family, the ES 300h stands out. Looking at all Lexus fuel economy data, it’s significantly more efficient than larger Lexus sedans like the GS and LS hybrids, catering to buyers who prioritize fuel savings alongside the luxury experience. If you look at ES MPG across all years, you will see consistently above-average fuel economy for the given vehicle class. For those considering other brands altogether, the Toyota Avalon Hybrid is similarly efficient, but it lacks the cachet and opulence of the Lexus.

Tips to maximize efficiency

Smooth acceleration is key to maximizing fuel efficiency in the ES 300h. Avoid sudden bursts of speed and try to maintain a steady pace. The hybrid system operates most efficiently when transitions between electric and gasoline power are gradual rather than abrupt.

Use the “Eco” driving mode, which modifies throttle response and climate control settings to prioritize fuel economy. While it might slightly reduce performance, the difference is often negligible in everyday driving, and the fuel savings can be significant over time.

Proper tire inflation is critical for optimal fuel efficiency. Check your tire pressure regularly and inflate them to the recommended level, which can be found on a sticker inside the driver’s side doorjamb. Underinflated tires create more rolling resistance, increasing fuel consumption.

Reduce unnecessary weight in the vehicle. Carrying extra cargo in the trunk or backseat adds to the vehicle’s load, requiring more energy to accelerate and maintain speed. Remove any items you don’t need to carry on a regular basis.

Anticipate traffic conditions and avoid hard braking. By paying attention to the road ahead and planning your stops, you can minimize the need for sudden deceleration and allow the regenerative braking system to capture energy and recharge the battery, further improving fuel efficiency.
