The best model for low Citroen DS3 Cabrio running costs is the lower-powered 1.2-litre petrol engine version. This emits 112g/km of CO2 so it’s cheap to tax. Fuel economy is a claimed 58mpg on the combined cycle.

There’s no diesel option available at launch, which is a shame because a sub-100g/km version could significantly lower running costs.
