The Citroën C3 offers a range of fuel-efficient powertrains, including petrol, mild-hybrid, and diesel options. Official figures for the latest petrol models indicate a combined consumption of around 52 mpg (Hybrid, 110 Hp, automatic), and up to 56.5 mpg (Petrol, 100 Hp, 6-speed manual)[5]. Independent tests and broader model-year data show real-world fuel economy typically ranging between 46 and 59 mpg, with older diesel engines achieving even higher figures, up to 70 mpg depending on driving conditions and model year[3].
Older diesel variants, such as the 1.4 HDi models, are noted for their low running costs and often return between 62 and 70 mpg in typical use[4]. Real-world user-reported efficiency places new petrol-powered C3 models at 13–15 km/l (approx. 36–42 mpg US, 43–50 mpg UK) in city driving, and 20–22 km/l (approx. 47–52 mpg US, 56–62 mpg UK) on the highway[6].
The all-electric Citroën e-C3 offers a 199-mile official range (likely translating to about 180 miles in everyday conditions) from its 44kWh battery[1]. For the crossover-styled C3 Aircross, the petrol version achieves around 48 mpg, while the hybrid delivers approximately 53 mpg[2].
