Gas ovens pretty much exclusively these days, and that’s a cost cutting thing for anyone wondering. On cheap models, the manufacturer uses the same burner for both broiling and baking so they don’t have to pony up to include two separate burners, valves, and igniters. In broil “mode,” you just put the food item immediately below the burner in the drawer so it’s much closer to the source of the heat which is now also conveniently above it rather than below it.
