Are Extended-Range EVs a Game Changer or a Dead-End Technology? - CleanTechnica

The article from CleanTechnica critically examines the role of extended-range electric vehicles (EREVs) in the evolving electric vehicle (EV) market, questioning whether they represent a breakthrough technology or a dead-end. EREVs combine a battery with a combustion engine that acts solely as a generator once the battery is depleted, differing from plug-in hybrids (PHEVs) where both engine and motor can drive the wheels. Despite recent growth in China—where EREV sales surged 79% in 2024 to about 1.2 million units, supported by government incentives—the technology remains niche in Europe, with only two models available. However, the touted benefits of EREVs, such as long total driving ranges and low CO₂ emissions, are misleading because much of the range relies on the combustion engine. Real-world data show these vehicles consume fuel at rates comparable to conventional petrol SUVs once the battery is drained. The article highlights that EREVs share the same fundamental shortcomings as PHEVs:
