The Sonata's combined fuel consumption is 5.6-6.9L/100km. Currently, there are 5 models of the Sonata available for sale. The GL Leading Edition and GLS Elite Edition have a combined fuel consumption of 5.6L/100km. The GLS Luxury Edition and GS Edition have a combined fuel consumption of 6.8L/100km. The TOP Flagship Edition has a combined fuel consumption of 6.9L/100km. The above figures are the NEDC combined fuel consumption, which is the data measured under the NEDC test procedure for combined driving conditions. The actual fuel consumption is higher than these values, ranging from 8.1-8.8L/100km. When driving, the following 5 tips can help reduce fuel consumption: When starting the vehicle, use a low gear, gently press the accelerator, and gradually increase speed. Avoid suddenly flooring the accelerator, as this can multiply fuel consumption. Light acceleration, light braking, and early braking: While driving, press the accelerator lightly to avoid sudden increases in engine RPM and prevent the car from shaking during operation, thereby making the vehicle more fuel-efficient. By anticipating road conditions and applying slow, even acceleration or braking, fuel economy can be improved by up to 20%. Maintain proper tire pressure: Keep tire pressure at the level recommended by the manufacturer. For every 2 PSI below the recommended value (approximately 0.2 in metric units relative to the standard pressure of 2.4), fuel consumption increases by 1%. Regular vehicle maintenance or inspections: Timely oil changes can reduce carbon buildup (carbon deposits can cause ignition issues, sluggish acceleration, increased fuel consumption, and in severe cases, even cylinder misfires). Regularly check and replace the air filter if dirty, and clean or replace the fuel injectors, spark plugs, and throttle body as per the recommended mileage. Close windows while driving. Driving with windows open increases wind resistance, which in turn increases the resistance the car faces, requiring more power and thus increasing fuel consumption.

















I've been driving a Sonata gasoline version for almost half a year, mainly for city commuting. During the morning and evening rush hours, the traffic is terrible, and the fuel consumption is usually around 10 liters per 100 kilometers. It's much better on weekends when driving on the highway, dropping to about 7 liters. There are many factors affecting fuel consumption, such as slower engine warm-up in cold weather leading to higher fuel usage, and the added burden of using air conditioning in summer. I prefer to maintain a gentle driving style, avoiding sudden acceleration and braking, which helps a lot with fuel efficiency. Additionally, the vehicle's load and road conditions are crucial; fuel consumption is lower when the car is empty. If you often drive on hilly roads or in windy areas, fuel consumption may fluctuate more. Regular maintenance like timely engine servicing can also optimize fuel efficiency, but I haven't paid much attention to these aspects and feel it's still reasonable.

The hybrid version of the Sonata is truly impressive. My friend drove it and measured the city fuel consumption at just 5.5 liters per 100 kilometers, staying around 6 liters on the highway. The key is its efficient electric system, which works in tandem with the gasoline engine to reduce energy consumption, making it both eco-friendly and cost-effective. Nowadays, many cars promote environmental concepts, and the Sonata hybrid saves over 30% more fuel than the regular gasoline version. In terms of driving style, smooth driving maximizes its advantages by reducing sudden stops and starts. I think with rising fuel prices, such low-consumption cars are particularly practical and offer great long-term value. Plus, with Hyundai's reliable technology, you don't have to worry much about charging habits.

I often drive the Sonata for long-distance trips, such as from Shanghai to Nanjing, with an average fuel consumption of 7 liters per 100 kilometers. Maintaining a steady speed of 90-100 km/h on highways is the most economical, while consumption slightly increases to 8 liters on hilly terrain. Engine temperature and wind speed are influencing factors, so it's advisable to warm up the engine before long journeys. The Sonata's lightweight design aids in fuel efficiency, but its taller body can reduce efficiency in strong winds. Overall, I'm quite satisfied, and it's suitable for family trips.

The fuel consumption of the Sonata varies depending on the engine model. The gasoline version averages around 8L/100km, slightly lower than the Passat but a bit higher than the Toyota Camry's 7.5L. Based on the data I've reviewed, the difference in fuel consumption is more noticeable in congested city driving. When choosing a car, it's important to pay attention to the official standard tests, as real-world driving conditions may vary. Models with higher fuel consumption typically offer stronger performance, while those with lower consumption are more economical. If you're buying a new car, comparing specifications is crucial to avoid regrets.

Managing the Sonata's fuel consumption effectively to avoid exceeding limits is not easy, but through gentle driving, I've kept the gasoline version at around 7 liters per 100 kilometers. Key tips include timely oil changes and cleaning the air filter to prevent excessive engine strain. Driving with windows closed and using cruise control can also save fuel. Based on experience, fuel consumption issues often stem from aging components, such as faulty oxygen sensors.
