The 2018 Hyundai Tucson performs above average in fuel economy. For the 2.0 - litre naturally aspirated petrol engine version commonly seen in the Malaysian market, the fuel consumption in city driving is about 8 - 9L per 100km, and it can drop to 6 - 7L per 100km during highway cruising. The 1.6 - litre turbocharged version further optimizes fuel efficiency through more advanced direct - injection technology, making it especially suitable for long - distance driving. The fuel consumption of this SUV is similar to that of its counterparts like the Honda CR - V or Toyota RAV4 in the same class. However, potential owners are advised to note that the actual fuel consumption can be affected by the hot climate in Malaysia and the stop - and - go traffic conditions. Regular maintenance, such as replacing the air filter and using engine oil with the appropriate viscosity, can help maintain the best fuel efficiency. Hyundai's 6 - speed automatic transmission strikes a good balance between smoothness and fuel economy. But keep in mind that there are fewer diesel models in Malaysia and the maintenance cost is slightly higher. Overall, the 2018 Tucson offers a reasonable choice between power and fuel consumption as a family SUV.
