Why DPF/GPF Remains Essential: Hybrid vehicles have surged in popularity thanks to their increased fuel efficiency, reduced emissions, and reduction in range anxiety when compared to EVs. Hybrid vehicles (combined full and plug‐in models) accounted for about 21.9% of new car registrations, compared to 19.6% for pure EVs in 2024.
However, did you know that your hybrid vehicle still relies on an advanced exhaust filtration system such as a Diesel Particulate Filter (DPF) for diesel engines and Gasoline Particulate Filter (GPF) for petrol engines?
Why Hybrid Cars Still Need DPF/GPF
Even though hybrid vehicles benefit from an electric motor’s support, the combustion engine still operates intermittently or under load. This means:
- Emissions are inevitable: Any internal combustion process produces particulate matter.
- Regulatory compliance: Governments continue to enforce strict emissions standards, making these filters a necessity.
- Long-term engine health: Keeping particulates in check can prevent long-term engine wear and maintain overall vehicle performance.
What is a Gasoline Particulate Filter (GPF)
Unlike diesel engines, traditionally petrol engines were not required to be fitted with particulate filters. This changed with the introduction of direct-injection petrol engines and new hybrid engine models. GPFs have become increasingly common to ensure that even petrol engines comply with current emissions standards and contribute to cleaner air by trapping the fine particulate matter.
So, both diesel and petrol hybrid vehicles are fitted as standard, with modern, intelligent emissions control systems called DPFs and GPFs to meet EU environmental regulations and maintain engine efficiency. While hybrid technology does reduce the overall emissions released and fuel used the combustion process still produces particulate matter that these filters are designed to capture.
Keeping your GPFs and DPFs clean is essential for optimal performance, improving fuel economy, and your long-term vehicle health.
By following DPF Fixer’s advice and best practices such as regular driving under proper conditions, monitoring engine performance, using high-quality fuels, and scheduling professional maintenance, you can ensure that your hybrid’s emission control system remains efficient. It is important to stay proactive with your hybrid’s maintenance so you can continue to enjoy the benefits of advanced technology combined with responsible driving
