The Hyundai i10 is known for its strong fuel efficiency, with the most efficient 1.0-litre petrol manual achieving up to 53.3 mpg (UK) under official combined cycle tests[1]. Versions with the automatic gearbox are slightly less efficient, typically a few mpg lower[1]. Real-world averages for most models are commonly reported between the low to mid 40s mpg (UK) range[2], although efficient driving can improve these figures.
The officially rated WLTP combined fuel economy for recent Hyundai i10 petrol versions typically falls between 49.6 and 56.5 mpg (UK), depending on engine and trim[2]. For reference, the automatic 1.0 16V (67 Hp) from earlier model years delivered an average of about 5.1 l/100km (about 55.4 mpg UK)[3].
Real-world user experiences sometimes show a wide range of results: some drivers of the 1.25 manual have reported around 50 mpg (UK) in mixed driving conditions[5], while others using older automatics have seen lower values, with claims near 10 km/litre (about 28.2 mpg UK) under less optimal conditions[5]. A recent fuel consumption test of the latest 1.0L manual reported impressive results as low as 3.9–5.5 l/100km (about 51–72 mpg UK) depending on driving style and conditions[4].
