Rafael Acevedo, Group Director for Diet Coke North America, explains the company's thinking behind its largest overhaul since the drink was introduced in 1982. Diet Coke is rolling out four new flavors for 2018.

Acevedo explains the company spoke to over 10,000 people, or "style seekers" as he calls them, who are seeking adventure and bold, new flavors in their lives. Acevedo says all packaging graphics are changing, and so far they're testing significantly better than the older ones.

Acevedo assures customers Diet Coke's original formula will not be changing. The no calorie beverage will be getting four new flavors: Feisty Cherry, Ginger Lime, Twisted Mango, and Zesty Blood Orange.
