Cars driven by Australians are consistently consuming more fuel than their marketed efficiencies, investigations have found, with the latest tranche of “real-world” testing finding one car used 31% more petrol than its advertised rate.
The Australian Automobile Association testing – funded by the federal government – found that eight of the 21 cars examined in its latest round of testing consumed more petrol in real road driving conditions compared with the efficiency rates calculated by their manufacturers in laboratories.
