The average fuel consumption of a 1.5-litre engine varies depending on vehicle type, technology, and driving conditions, but typically ranges from 5.2 to 6.2 litres per 100 km (L/100 km) under combined driving cycles[2]. This translates to approximately 0.052 to 0.062 litres per kilometer.
For specific models and driving contexts:
- Recent Ford 1.5L EcoBoost engines have combined cycle fuel consumption figures between 5.2 and 6.2 L/100 km, or 0.052–0.062 L/km[2].
- Real-world estimates for 1.5-litre petrol engines generally result in 15 to 20 km per litre, corresponding to 0.05–0.067 L/km[3].
- Highly efficient versions, such as hybrids or modern diesels, can reach as low as 4.4–4.8 L/100 km (0.044–0.048 L/km) in combined cycles[1].
Consumption in urban (city) driving is typically higher, with figures up to 7.8 L/100 km (0.078 L/km), while extra-urban (highway) driving can be as efficient as 4.3–5.2 L/100 km (0.043–0.052 L/km) for 1.5-litre engines[2].
