The range of electric cars in colder temperatures is, on average, 29.9 per cent less than advertised,an investigation by What Car magazine has found.

No. Heating a gas/diesel powered vehicle simply takes heat that is produced by running the engine. You don't use more fuel by running the heater, than by not running the heater.

Electric heat in an EV is very different.

If you have a car that heats the interior exclusively on “bleed air” from the engine, your car would never become warm in sub freezing conditions.

Extra energy is always needed to heat the car, but an ICE is a bit more efficient because it can use spare heat from the engine.

So, where does an ice get the extra heat?

By either fuel or electricity.

My Volvo V90 has an extra heater in the right wheel arch that takes fuel from the tank and heats the engine and interior if it’s too cold outside, or to preheat/cool the car when parked. I can hear the extra heater kicking into action as soon as it’s below 5 c(40F), and it will stay on for about 30 minutes. On long trips it will kick in now and then to be able to keep the interior temperature at around 20c.

I know that Volvo in different (warmer) markets have replaced the fuelburner with an electrical one.

From the homepage (using google translate):

The heater has two sub-functions which in different situations help to heat the passenger compartment or the engine. The heater has two sub-functions: Parking heater – heats the passenger compartment if needed when the parking climate preconditioning is activated. Additional heater – heats the passenger compartment and the engine while driving if necessary
