Pepsi Max was renamed Pepsi Zero Sugar in the United States in 2016.
Pepsi Max was introduced internationally as a no-sugar cola, and the brand used that name in many markets. In the United States, PepsiCo changed the name to Pepsi Zero Sugar in 2016, presenting it as a zero-calorie cola with a stronger connection to the company’s Pepsi identity.
The product is different from Diet Pepsi, which remains a separate reduced-calorie cola with its own formula and branding. The naming change therefore did not mean that Diet Pepsi was discontinued or renamed.
Names vary by country, which can cause confusion when comparing Pepsi products internationally. “Pepsi Zero Sugar” is the U.S. name, while “Pepsi Max” continues to be used in several other markets.
