The Fiat Uno is known for its economical fuel consumption, which varies depending on engine type and driving conditions. For example, the 1.1 i (51 Hp) model from 1995–2002 averages around 6.5 l/100 km (36 US mpg, 43 UK mpg, 15 km/l)[4]. Diesel versions such as the 1.7 D (58 Hp) and 1.9 D (60 Hp) typically consume about 6.2 l/100 km (38 US mpg, 46 UK mpg, 16 km/l)[4].
For urban driving, the 1.1 i (51 Hp) can consume about 7.6 l/100 km, while extra-urban consumption improves to roughly 4.8 l/100 km[2]. The smaller 1.0 i.e. (46 Hp) model returns about 6.7 l/100 km in the city and 4.6 l/100 km outside of town[7].
Performance and fuel consumption in real-world conditions may differ. Owner reports suggest an average of around 7.5 l/100 km (37 mpg) for typical around-town driving, though factors like driving style can alter these results[3].
Enthusiasts and upgrade providers also mention that adding specific performance chips may improve fuel efficiency by up to 5 miles per gallon, depending on usage and vehicle condition[5].
