The type of heat transfer from the Sun is radiation heat transfer, which is the transfer of heat through electromagnetic radiation
The distance of the Sun to the Earth is several million kilometers away, with the space between being composes of vacuum and the nuclear reaction in the Sun's core generates vast amount of electromagnetic radiation that is transferred all across the universe and reaches the Earth as visible light and radiant energy at the speed of light
The radiant energy transferred from the Sun heats up the Earth, including the car's interior.
