PHEV — plug-in hybrid
A plug-in hybrid carries both a combustion engine and a battery large enough to drive a meaningful distance on electricity alone, with the engine driving the wheels when needed.
The defining feature is that both power sources can drive the car, and the battery can be charged from the grid rather than only by the engine. That distinguishes it from a conventional hybrid, which recharges only from braking and from the engine and cannot be plugged in.
Why it matters when buying
The category has a reputation problem in Europe, earned honestly: company fleets bought them for the tax treatment and a large share were never plugged in, so the real emissions bore no relation to the certified figure. Regulators noticed, and the test procedure has been tightened to weight the results towards how the cars are actually used.
Chinese manufacturers have approached the category differently from European ones, with markedly larger batteries and electric ranges that cover a normal commute without the engine starting. That changes the arithmetic: a plug-in whose battery covers daily driving behaves like an electric car on weekdays and a combustion car on holidays, which is the case the category was originally supposed to serve.
The practical questions are the electric range under the current test cycle, whether the car can fast-charge or only accept alternating current, and how the local tax regime treats the category this year. The last one moves more money than the first two and is market-specific.
