The Kia Carnival has an official combined fuel consumption of approximately 8.3 km/L. For a large MPV measuring over 5.1 metres in length and weighing over 2 tonnes, this fuel consumption figure is considered reasonable. Actual fuel consumption will vary depending on load, road conditions, and driving habits, with city driving consuming more than highway driving.
Kia Carnival 嘅官方綜合油耗約為 8.3 km/L。以一部車長超過 5.1 米、車重超過 2 噸嘅大型 MPV 嚟講，呢個油耗表現算係合理。實際油耗會因載重、路面狀況同行駛習慣而有所不同，市區行車油耗會比高速公路高。
