Diesel Bad is the new masculine fragrance from Diesel, coming out mid-2016, announced as a daring and sophisticated, addictive and fresh woody fragrance. It is apparently the first one that combines notes of tobacco and caviar, discovering the fresh salty side of the woody scents territory.

Perfumers Anne Flipo and Carlos Benaim made Bad to be "a game of seduction" that begins with an "exciting rush" of citrus and cool spice top notes. Pungent bergamot "bites" with freshness, revived by cardamom and lavender. Caviar gives a provocative and erotic touch “like a trickle of sweat on a man’s chiseled body.” Masculine and rough notes of tobacco and orris root facilitate the heat of the composition.

The face of the perfume is American actor and model Boyd Holbrook. The bottle design evokes a typical "bad boy" image, recalling the biker leather jacket. The texture that looks like leather is actually micro-engraved glass, using a technique developed by Pochet du Courval. The transparent "Bad" logo reveals the copper color of the liquid.
