What is the fuel consumption of Lexus ES 300h/L/100km?
The Lexus ES 300h typically uses about 4.5–5.0 litres of fuel per 100 kilometres in mixed driving. Official figures vary by testing cycle: WLTP around 4.4–4.8 L/100 km, while US EPA ratings are about 5.0–5.3 L/100 km.
This article explains how those numbers are measured, what they mean for everyday driving, and how real-world results can differ across markets and conditions.
How fuel consumption is measured in the ES 300h
Fuel economy figures for the ES 300h come from different standardized tests used around the world. The most common are:
Before the list, note that the values below come from two main testing cycles used globally. They are not identical, but together they provide a basis for comparing efficiency across regions and trims.
- WLTP combined: approximately 4.4–4.8 L/100 km (used in Europe and many other markets).
- EPA combined (US): approximately 5.0–5.3 L/100 km (roughly 44–46 mpg US).
- Variations by drivetrain and trim: some variants may show slightly different results within these ranges.
Real-world driving often yields higher fuel use than the official test figures, due to factors such as city stop-and-go traffic, climate-control usage, and battery charging behavior in hybrid mode.
What affects the ES 300h’s fuel economy?
Fuel consumption in the ES 300h is influenced by how the hybrid system manages power between the petrol engine and electric motor, as well as how you drive and operate the vehicle.
Hybrid-system behavior
The ES 300h blends a 2.5-liter petrol engine with electric motors and a battery. Fuel efficiency is maximized when the system can rely on electric propulsion at low speeds and efficient engine operation during cruising, with regenerative braking helping to recharge the battery.
Drivers and conditions
City driving with frequent stops, high-speed highway cruising, weather extremes, payload, and even tire pressure can all shift real-world numbers. Gentle acceleration, steady speeds, and proper maintenance help approach the published figures.
Practical tips to improve fuel economy
To maximise efficiency in daily use, consider these approaches that align with the ES 300h’s hybrid design.
- Plan smoother, gradual acceleration and minimize rapid throttle inputs.
- Utilize the eco driving mode if available, and anticipate ahead to reduce braking.
- Keep tires inflated to the recommended pressure; underinflated tires increase rolling resistance.
- Use climate control conservatively; at lower speeds, the hybrid system can offset some comfort-system load.
- Maintain regular service intervals, especially spark plugs, air filters, and battery health checks.
- Lighten payload where possible; remove unnecessary roof racks or heavy items when not in use.
While these tips can help you approach the official figures, actual mileage will vary with driving style, road conditions, and climate.
Summary
The ES 300h’s fuel economy sits in the mid-range for modern hybrids. Official WLTP figures typically fall around 4.4–4.8 L/100 km, while EPA numbers in the United States are about 5.0–5.3 L/100 km. Real-world results depend on driving behavior, terrain, weather, and how the hybrid system is used. For buyers comparing models, consider both WLTP and EPA figures, and gauge how your daily routes might influence actual consumption.
