How the 2026 Citroen C5 Aircross running costs are calculated

Every figure on this page is calculated from official certified data — nothing is estimated, and no figure is carried over from a similar car:

• Consumption and CO₂ are the certified values recorded in UK Vehicle Certification Agency (WLTP), measured on the WLTP test cycle, taken across the 4 configurations held for this model-year.
• Annual cost is consumption × mileage × the market's current average price for petrol, at 12,000 miles a year.
• The roadworthiness test and road tax use the United Kingdom national figures shown above. Road tax is banded by CO₂ in most markets, so the exact rate depends on the variant you buy — the figure here is the market average, not a quote for one registration.
• Deliberately excluded: insurance, servicing, tyres, repairs and depreciation. They depend on the driver, the policy and the individual car, so putting a number on them would mean inventing one.
