What is the fuel consumption of a Ford Fiesta?
The fuel consumption of a Ford Fiesta varies by engine, transmission and market. In general, modern petrol EcoBoost variants achieve about 4.0–5.0 L/100 km on the combined WLTP cycle, while diesel versions tend to be around 3.0–3.8 L/100 km. In the United States, where the Fiesta was sold until 2019 with a 1.6-liter engine, combined fuel economy was typically in the low 30s mpg (roughly 7–8 L/100 km). Exact figures depend on year, trim and driving conditions.
Engine options and their typical fuel economy
Below is a concise guide to the main Fiesta engines and their approximate combined fuel economy ranges. Figures refer to standard European WLTP testing where applicable, and may differ for other markets or older model years.
- 1.0‑liter EcoBoost petrol (turbocharged three‑cylinder) – typically about 4.0–5.0 L/100 km (roughly 47–58 mpg) on a combined WLTP cycle, with minor variation between manual and automatic versions.
- 1.1‑liter petrol – generally around 5.0–5.5 L/100 km (roughly 42–46 mpg) combined WLTP.
- Diesel 1.5‑liter TDCi – usually about 3.0–3.8 L/100 km (roughly 62–78 mpg) combined WLTP, depending on configuration and drive style.
- United States market (discontinued after 2019) 1.6‑liter petrol – EPA combined typically in the low 30s mpg (around 7.5–8.0 L/100 km), with variations by transmission and year.
These figures illustrate typical ranges; actual consumption will vary with city vs highway driving, loads, tire choices, and maintenance. WLTP numbers are designed to reflect real-world driving more closely than older standards, but real-world results can still diverge from lab figures.
Testing standards and how to compare numbers
Fuel economy figures are published under different testing regimes depending on the market. Europe uses WLTP, while the United States uses EPA testing. Because WLTP and EPA test cycles yield different numbers, always compare figures within the same testing standard and year for accuracy. Also note that newer engines or updates can shift efficiency slightly from one model year to the next.
In practice, if you’re choosing a Fiesta today, diesel variants will offer the best mileage on long highway journeys, while petrol EcoBoost engines provide a balance of performance and efficiency for city and mixed driving. Always consult the official Ford specifications for the exact year and trim you’re considering.
Notes on market status
The Ford Fiesta has largely been phased out in many markets, with production winding down in Europe in the early 2020s. For current purchases or used-car evaluations, rely on the specific model-year data and the local Ford official spec sheets or trusted fuel-economy databases to obtain precise WLTP/EPA figures for that exact configuration.
Summary
Fuel consumption for the Ford Fiesta depends on engine choice, transmission and market. In Europe, expect combined WLTP figures roughly in the 4.0–5.0 L/100 km range for petrol EcoBoost engines and about 3.0–3.8 L/100 km for diesel variants; US-specifications (historical) sit around the low 30s mpg. Real-world results vary with driving style and conditions, so use official spec sheets for the exact year and trim you’re evaluating. Overall, diesel options generally offer the best efficiency, while turbo petrols provide a solid balance of performance and economy.
