👉 Volvo's "fumes" refer to the company's historical and ongoing issues with air quality and emissions, particularly stemming from its diesel engines. In the early 2000s, it was revealed that some Volvo diesel vehicles emitted significantly higher levels of particulate matter (PM) than legally allowed, leading to public health concerns and regulatory scrutiny. This was partly due to the use of "clean diesel" technology, which, while reducing nitrogen oxide emissions, could still produce harmful particulates under certain conditions. Over time, Volvo has worked to address these issues through improvements in engine technology, exhaust aftertreatment systems, and stricter adherence to emission standards. However, the legacy of these past practices continues to influence public perception and regulatory oversight of the brand.
