Technical data comes from official manufacturer materials and we do our best to verify it, but a manufacturer can change a specification without notice and mistakes do happen. Confirm the figures with a dealer before you buy — we accept no liability for decisions made on the basis of this data. Full disclaimer
Range, consumption and weight are given for the base configuration: manufacturers homologate them as a band of values that depends on wheels and equipment (e.g. 533–592 km), and we take the lightest variant, on the smallest wheels — i.e. the most favourable. The same model on larger wheels will travel a shorter distance.
