Heat the oven to 350 degrees. (Since I use metal loaf pans I prefer to bake at 325 degrees to avoid overbrowning)
Grease two 8x4 loaf pans. (I had 9x5 loaf pans, which is fine. My baking time was around 45 minutes.)
Combine the sugar, oil, eggs, and vanilla in a bowl.
Stir in the grated zucchini.
In a separate bowl combine the flour, salt, baking powder, baking soda, and cinnamon.
Add the dry mixture to the wet mixture and stir until combined. Don't overmix.
Pour the batter into prepared pans, dividing equally.
Bake for 50-60 minutes or until done (a toothpick comes out clean).
