The 2.5 D4D (widely known as a 2.5L turbo diesel) typically achieves fuel consumption figures ranging from about 8 to 13 km/L depending on driving conditions, vehicle load, and maintenance[1][3].
On average:
- City driving: 8 to 12 km/L is common[3].
- Highway driving: 10 to 13 km/L can be expected with steady speeds and light loads[3].
- Mixed conditions: Many owners report combined fuel consumption in the range of 9 to 11 km/L[1][3].
Fuel consumption varies due to factors such as driving style, tire pressure, load, and road conditions. Some users report figures as low as 6.5 km/L under heavy or unfavorable use, while others achieve up to 13.9 km/L on long highway trips with conservative driving[1][3]. Specific examples include:
- Factory settings: Typically 8–9.5 km/L, with extremes from 6.5 up to 10.5 km/L depending on use[1].
- Long highway cruise: Up to 6.5 L/100km (approximately 15.4 km/L) at around 90 km/h for some 2.5L turbo diesels, though this can vary by specific model and transmission[2].
- Modern listings: Diesel 2.5L engines across brands generally fall in the 7–10 L/100km (10–14 km/L) range under mixed conditions[7].
While real-world results vary, these figures provide a practical estimate for most 2.5 D4D-powered vehicles under normal usage.
