Popular Australian models that use up to 35 percent more fuel than claimed

The results of the newest round of the Australian Automobile Association (AAA) of his Fuel and Emissions Real-World Testing Program have been released and it is bad news for various popular vehicles.

In 2022, the Federal Government assigned $ 14 million to the AAA-the peak organ for the state-based autoclubs in Australia, such as the NRMA, RACV and RACQ-OM Real-World tests on 200 vehicles that were previously only tested under Laboratory Conditions .

The AAA has now published the results of 84 vehicles that it has tested, with the newest, sixth round with details about 14 vehicles.

Of these 14 vehicles, only three improved or agreement of fuel consumption of their manufacturer (liters per 100 km).

The Mitsubishi Outlander was the only vehicle that used less fuel than what the car manufacturer achieved in the laboratory tests, which consumed two percent less petrol in the AAA testing.

Nissan’s Patrol and Isuzu’s MU-X 4 × 4 both had negligible differences with their laboratory test claims, but they were among the two thirsty tested vehicles.

However, that left 11 vehicles with Real-World fuel consumption figures higher than those in the laboratory tests, with the Mitsubishi Triton, Nissan X-Trail, Kia Cerato, Ford Everest V6, Toyota C-HR Hybrid, Hyundai i30, Kia Picanto, MG 5, Mazda CX-5, Suzuki Swift Hybrid and Mazda 2 who all exceed their claims.

In the case of the Mazda 2, it turned out to be 35 percent more fuel when it is tested by the AAA compared to what the car manufacturer claims. It was a similar story for the new Suzuki Swift hybrid, which consumed 31 percent more gasoline.

Although the MU -X may have been one of the few vehicles that does not exceed the fuel consumption claim, it was the only vehicle that produced more nitrogen oxide (NOx) emissions in testing than mandatory, with the limit of 180 mg/km/km For diesel vehicles for diesel vehicles for diesel vehicles.

It turned out to be 314 mg/km, although curious this is less than the previously tested MU-X 4 × 2, which used less fuel but higher NOx emissions of 372 mg/km.

The AAA and Isuzu Ute Australia have been contacted for comment.

In contrast to previous announcements of results, the AAA has not included the Baseline Lab test results of the CO2 emissions of each vehicle, only what the tests have found.

This article is updated accordingly when the data becomes available.

All Real-World road tests of the AAA are performed on a 93 km loop in and around Geelong. Test protocols are based on legislation in the European Union, but developed for Australia with consultation between the peak group and local regulators and industry.

“These results show that real tests are needed to help consumers and to prevent the buyers of fleet from buying a vehicle that produces more emissions and higher operating costs than advertised,” said AAA director Michael Bradley in a media statement.

“While some cars perform according to the information at the point of sale, our program reveals that much, if not most, does not.

“Testing cars in real Australian driving conditions will help sort the wheat of the chaff when it comes to cars that deliver fuel consumption that corresponds to their mandatory laboratory test results, and it will act as a supplementary audit regime for the NFS [New Vehicle Efficiency Standard].

“The program cooperates with the NFS to make the national vehicle fleet cleaner and more efficient more efficiently.”

The AAA has not yet released test results for EVs, which must be tested for the test this year.
