Study reveals that plug-in hybrid cars are more polluting than expected

SIC Notícias4 September 2026 at 06:20

A study revealed that plug-in hybrid cars are significantly more polluting than official certification tests indicate. The research showed that the average real CO2 emissions of these vehicles were 3.5 times higher than declared values in 2021, rising to 4.6 times above the predicted in 2023. This indicates that the difference between real values and certification values increased considerably over the two years analyzed. The disparity raises questions about the effectiveness of current tests in measuring the real environmental impact of these vehicles.
