How do PHEVs heat the interior?

Do modern PHEVs use the ICE motor to heat the cabin?

Asked on 23 January 2024 by Keith Moat

Answered by David Ross
Most modern PHEVs will heat the cabin using whatever energy supply is being used to power the vehicle at the time, whether this is the drive battery or the internal combustion engine, but typically extended running in EV mode and the heater on wlil cause the engine to kick in earlier.
