Citroën C3 hatchback - MPG, running costs & CO2
Diesels are the most efficient, but petrol Citroen C3s cost much less to buy and are nearly as cheap to run
Despite the current trend for more and more manufacturers to go for hybrid or electric powertrains, Citroen has stuck to proven petrol and diesel engines for the C3, keeping it as affordable as possible. They’re all impressively efficient and shouldn’t cost too much to run. Meanwhile, purchase prices are pretty low and Citroen dealers are renowned for generous discounts. This could, however, have a negative impact on the car’s residual values.
Citroen C3 MPG & CO2
As frugal as the diesels are likely to be, the petrols are also pretty impressive. The least powerful petrol is the most efficient; the 82bhp version manages over 50mpg but emits 130-131g/km of CO2, giving it a middling BiK rating. The other 1.2-litre PureTech engine with 109bhp isn't much thirstier, and it's this engine that we recommend if you can afford it as the extra power makes it much easier to keep up with tra
The 99bhp diesel engine in the Citroen C3 is the star of the economy show. Go for the 1.5-litre four-cylinder diesel engine and you should get some impressive figures, as Citroen claims up to 67mpg - similar figures to a Toyota Prius hybrid. The diesel's CO2 output and BiK band are also quite low (117-118g/km), and it occupies a lower BiK band than petrol versions. Diesel buyers have a smaller choice of trim levels - the engine can’t be chosen on the Feel trim lev.
The Citroen C3’s three-year/60,000-mile warranty is pretty standard for the class, matching the likes of the Ford Fiesta, Skoda Fabia, SEAT Ibiza and Volkswagen Polo, while the Honda Jazz has a 90,000-mile limit on its three-year cover.
It is, however, slightly behind some other rivals. For example, both the Toyota Yaris and the Hyundai i20 come with a five-year warranty, but the Toyota is limited to 100,000 miles, whereas the Hyundai has no mileage limit. Finally, the Kia Rio gets a very impressive seven-year/100,000-mile warranty.
The 82bhp PureTech model is cheapest to insure, in group 13, while the 109bhp petrol is in group 22. The diesel BlueHDi is also in group 22, which is a similarly broad spread to rivals like the outgoing Peugeot 208, but still fairly high for a supermi
