In mixed use driving mainly Town and Motorway the Computer tells me I get 11.3L/100Km. On a recent gentle run with the family (2 adults and 2 children plus luggage) to Oman this improved to 9.5L. Hardly Great.
oops. Right, "hardly great". Especially considering onboard computers tend to display "optimistic" values. So much to contemporary (2009) cars as considered to a 1999 model with an engine that was developed in the early 70s. (And yes, the 166 is equipped with all contemporary gimmicks and weighs 1550 kg empty, so it's not a lightweight vehicle)
