* - Difference between advertised and user reported fuel economy has been calculated taking into account only those car versions for which information is available both on the fuel consumption specified by the manufacturer and reported by users.
User-reported fuel consumption may not accurately represent all users' experiences due to variables such as driving conditions, driving style, technical condition of the vehicle, and other circumstances. Thus, it should not be relied upon as a representative indicator.
