I inquired and according to a company rep, the brown sugar is added to the chain's pepper bacon in each restaurant before cooking.
The three new sandwiches are the Brown Sugar Bacon BLT, the Brown Sugar Bacon & Roast Beef, and the Brown Sugar Bacon & Pit Smoked Ham.
The Brown Sugar Bacon BLT (pictured above) features three strips of brown sugar bacon plus three strips of pepper bacon, tomatoes, lettuce, and mayo on a King's Hawaiian bun.
