Hybrids, petrol cars and BYD EVs caught short on range and fuel efficiency claims

Recent tests conducted by the Australian Automobile Association have revealed that several popular hybrid, petrol, and electric vehicles fall short of their manufacturers’ advertised fuel efficiency and range claims. The association tested 17 vehicles under real-world driving conditions along a 93km route in Victoria, finding that seven models consumed more than 10 per cent extra fuel compared to their laboratory figures. Notably, the GWM Jolion Hybrid exceeded its official fuel consumption by 27 per cent, while the Audi Q5 mild hybrid and GWM Haval H6 Hybrid also used significantly more petrol than expected. The findings also highlighted discrepancies in electric vehicle range, with BYD’s Dolphin hatchback and Sealion SUV both failing to meet their advertised distances by around a quarter. The Dolphin managed 313km against a claimed 410km, and the Sealion covered 469km instead of the promised 576km. These shortfalls come amid rising fuel prices and supply concerns linked to geopolitical tensions in the Middle East, as well as a surge in low-emission vehicle sales, intensifying the importance of accurate consumer information. Michael Bradley, managing director of the Australian Automobile Association, urged consumers to approach manufacturer claims with caution and seek independent data before purchasing. He emphasised the critical need for buyers to understand the true running costs and performance of vehicles, given the widespread discrepancies uncovered. Bradley’s comments reflect ongoing concerns about the reliability of official fuel consumption figures, especially in light of the 2015 Volkswagen emissions scandal that exposed widespread manipulation of laboratory test results. While most vehicles tested underperformed relative to their official figures, there were exceptions. The Subaru Forester AWD and Chery Tiggo 8 Pro both demonstrated slightly better fuel consumption than advertised, using one and two per cent less petrol respectively. However, the broader trend remains concerning, with more than three-quarters of petrol, diesel, and hybrid vehicles failing to meet lab test results, and none of the electric cars achieving their claimed range. The association’s Real-World Testing Program, launched in 2023, continues to provide crucial transparency for consumers navigating the evolving automotive market.
