The fuel efficiency performance of Hyundai Sonata depends on the specific engine model and driving mode. Take the 2.0L naturally aspirated version, which is relatively common in Malaysia at present, as an example. Its official fuel consumption is approximately between 6.5 - 7.5L/100km on highways and 8.5 - 9.5L/100km in urban areas. The combined fuel consumption is around 7.5 - 8.5L/100km. Overall, its fuel economy is just average, which is slightly inferior to Japanese sedans in the same class (such as the Toyota Camry or Honda Accord), but still within a reasonable range.
If it's the newer 1.6T turbocharged version (available in some markets), the combined fuel consumption could be optimized to 6.8 - 7.5L/100km, making it more suitable for drivers with higher requirements for fuel efficiency. In recent years, Hyundai has also been promoting the hybrid version of the Sonata (like the Sonata Hybrid). For this type of vehicle, the fuel consumption can be as low as 5 - 5.5L/100km when driving in urban areas, which is more suitable for users who often encounter traffic jams.
The actual fuel consumption is also affected by driving habits, road conditions, and maintenance status. Regularly changing the engine oil and maintaining proper tire pressure can help optimize fuel efficiency. Generally speaking, the Hyundai Sonata isn't the most fuel - efficient model in its class, but its fuel economy can still meet the daily needs of most families.
