Experts believe the heightened risk comes from combining an internal combustion engine with battery packs and electric motors. This mix makes the vehicle more complex to manage and, as a result, raises the chance of a fire. In practice, more components also mean more interfaces that must work together flawlessly—a demanding setup even for well‑engineered hybrids.

The article emphasizes that first responders need dedicated training and equipment to put out fires in hybrid vehicles effectively. As noted in the report, in March 2025 Ford announced a recall of several thousand Ford Kuga plug-in hybrids after identifying a serious short-circuit risk that could significantly increase the likelihood of a fire.

Specialists also point to the greater mass of hybrid cars as an added hazard. The extra weight of batteries and electric motors affects how a vehicle behaves and how energy is distributed in a crash—factors that can influence outcomes when something goes wrong.
