The internal combustion engine remains a significant source of emissions, particularly during cold starts and high-load conditions. Additionally, the production of batteries for HEVs carries its own environmental impact, including the extraction of raw materials and energy-intensive manufacturing processes.

One of the key limitations of current HEV technology is the relatively small battery capacity, which restricts the vehicle's ability to operate in pure electric mode for extended periods. This limitation results in more frequent engagement of the internal combustion engine, leading to higher emissions compared to fully electric vehicles. Furthermore, the complexity of HEV powertrains can lead to increased vehicle weight, potentially offsetting some of the efficiency gains.

Emission control systems in HEVs, while more advanced than those in conventional vehicles, still struggle to completely eliminate harmful pollutants such as nitrogen oxides (NOx) and particulate matter. The intermittent operation of the internal combustion engine in HEVs can also pose challenges for maintaining optimal catalyst temperatures, potentially reducing the effectiveness of emission control systems.

As global emission targets become increasingly stringent, the limitations of current HEV technology become more apparent. Many regions are implementing zero-emission vehicle mandates or setting aggressive targets for fleet-wide CO2 reductions that may be difficult to achieve with HEVs alone. This has led to a growing focus on plug-in hybrid electric vehicles (PHEVs) and fully electric vehicles (EVs) as potentially more viable long-term solutions for meeting emission targets.

To address these limitations and better align with global emission targets, HEV technology must evolve. This may include the development of more efficient engines specifically designed for hybrid applications, larger battery capacities to extend electric-only range, and advanced materials to reduce vehicle weight. Additionally, improvements in power electronics and thermal management systems could further optimize the overall efficiency of HEV powertrains.
