Many car models have significantly higher real-world fuel consumption rates than the manufacturer’s advertised numbers

The results published by AAA showed that many of the models had significantly higher fuel consumption than what the manufacturers had claimed.

In particular, the organization stated that 7 out of the 13 models had fuel consumption deviations within the allowed range (less than 5%), while the remaining 5 models had deviations of 9-20% between the stated figures and the actual test results.

The BMW X3 2021 had the largest discrepancy, with fuel consumption exceeding the manufacturer’s claims by over 20%. The MG3 2023 had a deviation of 19%, the Audi Q5 2022 consumed over 17% more fuel, and the Toyota Yaris Cross Hybrid 2021 had a fuel consumption that was 12% higher than the factory test results.

In contrast, the Kia Carnival 2023 and Toyota Camry 2022 had lower results, with deviations of -7% and -1%, respectively, compared to the manufacturer’s claims.

In addition to fuel consumption testing, AAA also measured the emission levels of the aforementioned models and compared them to the figures provided by the manufacturers. As a result, 3 models from South Korea, namely the Kia Carnival, Hyundai Staria, and Kia Sportage, had nitrogen oxide emissions exceeding the regulated limit.

Notably, the MG3 not only had higher fuel consumption than the manufacturer’s claims but also had carbon monoxide emissions that were 85% higher than the limit.

The emission tests conducted by AAA were sponsored by the Australian government and began following the infamous “Dieselgate” scandal involving Volkswagen. The tests were carried out in Victoria, Australia, and strictly adhered to the regulations set by the European Union.

This is the second independent testing conducted by AAA since its inception in 2017. According to Carscoops, in this round of testing, AAA focused on medium-sized and small SUVs and MPVs.
