Three-Quarters of Australia's New Cars Guzzle More Fuel Than Advertised

A recent study by the Australian Automobile Association has uncovered a concerning trend in the fuel efficiency of new vehicles sold in Australia. The testing found that three-quarters of new petrol, diesel, and hybrid cars are using more fuel on the road than the mandatory lab ratings would suggest.

This discrepancy between real-world and advertised fuel consumption could pose a significant challenge for Australia as it tries to reduce transport emissions and meet its climate targets. Vehicles with higher actual fuel usage than expected may contribute to the country's difficulties in curbing greenhouse gas output from the transportation sector.

The latest round of testing by the association confirmed that 76% of new models failed to live up to the fuel efficiency promises made by automakers. This trend has persisted over multiple rounds of testing, indicating an ongoing issue with the accuracy of mandatory lab testing procedures in reflecting true on-road performance.

"Another 10 cars have failed to live up to fuel efficiency promises when tested in the real world, adding to Australia's difficulties in reducing emissions from transport," the report states.

The discrepancy between lab and real-world fuel consumption is not a new phenomenon, but it continues to be a thorn in the side of policymakers and consumers alike. Automakers argue that lab tests provide a standardized way to compare vehicles, but critics contend that these tests fail to account for the complexities of real-world driving conditions, such as traffic, weather, and driver behavior.

As Australia works to curb its transport emissions and transition to more fuel-efficient and environmentally-friendly vehicles, the findings of this latest report underscore the need for more accurate and representative testing methods that better reflect the true fuel usage of new cars on the roads.

The Australian Automobile Association's testing program is an important step in holding automakers accountable and providing consumers with more transparent information about the actual fuel efficiency of the vehicles they are considering purchasing. By addressing this disconnect between lab and real-world performance, policymakers and the industry can work together to develop solutions that help Australia make meaningful progress towards its emissions reduction goals.
