In English there are no masculine or feminine forms. English uses gender specific nouns for male or female such as male and female.
The noun 'automobile' is a neuter noun, a word for something that has no gender.
Auto and automobile are feminine nouns in French.
Feminine
Objects are not feminine or masculine, specific words are. If there's more than one word for the same object, they don't necessarily have to have the same gender. So you'd need to specify which particular word you meant. The ones I know of (voiture and automobile) are feminine, but there could be a masculine one I'm unaware of.
