Fuel Efficiency of the 2017 Toyota AQUA

Hello everyone,

I wanted to share my experience regarding the fuel efficiency of my recently purchased 2017 Toyota AQUA. A few weeks ago, my driver took the car on a trip covering a total distance of 1,300 kilometers between Islamabad and Lahore. To my surprise, the calculated fuel average was only 16 kilometers per liter.

Ive heard that its common for the AQUA to achieve averages of 20 to 22 kilometers per liter, regardless of driving style. During the journey, the average speed ranged from 130 to 150 km/h on the motorway, and we used high-octane fuel while keeping the Eco mode activated. Additionally, all oil filters and fluids were recently updated.

Given these circumstances, do you think I should have the vehicle checked?

It sounds like the fuel efficiency of your 2017 Toyota Aqua is lower than expected, especially considering that you were using high-octane fuel, driving in Eco mode, and maintaining the car well. Here are a few factors that could explain the lower fuel average:

High-Speed Driving: The average speed of 130-150 km/h is quite high, and while the Aqua is a fuel-efficient vehicle, high-speed driving typically reduces fuel efficiency. Driving at higher speeds increases wind resistance and engine load, which can significantly lower the fuel economy.

Fuel Efficiency at High Speeds: The Aqua is designed for optimal efficiency at lower speeds typically between 50-80 km/h. On highways o r motorways, the fuel economy tends to when driving at speeds above 100 km/h.

Eco Mode: While Eco mode helps optimize fuel efficiency by adjusting throttle response and air conditioning use, it doesn’t drastically improve efficiency at high speeds, especially on long trips.

Other Factors to Consider:
Tire Pressure: Ensure the tires are inflated to the recommended pressure. Under-inflated tires can lower fuel efficiency.
Driving Conditions: If there were any inclines, heavy traffic, o r frequent braking, it could also impact fuel consumption.
Hybrid Battery Health: If the hybrid battery is not functioning at its optimal capacity, it might reduce fuel efficiency. Regular diagnostics using apps like Dr. Prius could help assess battery health.

Should You Get the Vehicle Checked?

While a fuel average of 16 km/l is lower than expected, it’s likely due to the high-speed driving. However, if youre concerned about it o r if the fuel efficiency doesnt improve at lower speeds, it would be a good idea to:

Check the hybrid battery health.
Inspect tire pressure and condition.
Ensure there are no engine issues like clogged air filters o r malfunctioning sensors.
Consider getting the vehicle diagnosed by a professional to rule out any potential issues.

In short, its not uncommon for the fuel economy to at high speeds, but if the issue persists, it’s worth getting the car checked to ensure everything is functioning as it should.
