Citroen is refreshing its C1 city car with a facelift, an engine upgrade and a posher interior for 2009. A cleaner, more efficient version of the 68bhp 1.0-litre petrol engine will be on offer which, Citroen claims, returns 62.8mpg (compared with 61mpg before) and emits 106g/km CO2 (previously 108g/km).Exterior changes will bring the C1 into line with newer models in Citroen’s range. An altered front end features a larger grille and redesigned headlights, echoing the city car’s recently facelifted big sibling, the C2. Sharp new alloys complete the makeover. Inside the updated C2, new cabin materials and upholstery are intended to boost quality. Full details on UK trim, equipment and prices won’t be confirmed until the revised C1 is launched early next year. We expect a slight increase over the current model, which starts from £7545.
