What's the difference between a sunroof and a moonroof? Well, "Moonroof" is a term coined by Ford Motor Co. in the 1970s to describe a specific type of sunroof. Traditionally, sunroofs were not made of glass but rather metal, just like the rest of the roof. They had handles and could pop up or slide back on tracks. Moonroofs are made of glass and have motors to slide them back and forth, and have a cardboard visor below them to shut out all light and give the interior a continuous feel, as if the hole in the roof wasn't there at all.
Today, the terms "sunroof" and "moonroof" appear to be used interchangeably.
