The Toyota Quantum 2.5 diesel (D-4D) typically achieves an average fuel consumption of about 9.0 to 10.4 litres per 100km under mixed driving conditions, depending on load and driving style[5]. This translates to an average of around 9.7 km/l, or approximately 10.3 litres/100km in ordinary use[5].
This figure is considered economical for a vehicle of its size and purpose, especially with its robust 2.5L D-4D common rail turbo-diesel engine designed for efficiency and reliability[1].
