2025 cars from Toyota, Chery, Hyundai, Kia, and MG exceed advertised fuel use and emissions in real driving, AAA finds.

The Australian Automobile Association (AAA) found that many 2025 vehicles, including models from Toyota, Chery, Hyundai, Kia, and MG, fall short of advertised fuel economy and emissions claims in real-world driving, with some showing up to 21% higher fuel consumption and increased CO2 emissions. The Toyota Camry and Chery Tiggo 4 Pro had the largest gaps, while the BMW X5 and Mercedes-Benz GLA performed better than lab results. The AAA’s government-funded real-world testing program aims to improve transparency amid rising fuel costs and stricter regulations, though industry groups criticize the method for variability due to traffic, weather, and driving style. Detailed results are available on the AAA’s website.
