Diet Coke
Diet Coke does not use a modified form of the Coca-Cola recipe, but instead an entirely different formula. The controversial New Coke, introduced in 1985, used a version of the Diet Coke recipe that contained high fructose corn syrup and had a slightly different balance of ingredients. In 2004, Coca-Cola introduced Coca-Cola C2, which it claims tastes much closer to Coca-Cola but contains half the carbohydrates. In 2005, the company introduced Coca-Cola Zero (replaced by "Coca-Cola Zero Sugar" in 2017), a sugar-free variation of regular Coca-Cola.
Jolt Cola
In 2005, Jolt Cola revamped its product line. Jolt Cola changed its logo, and came in "battery bottles" (that resemble the shape of a AA battery) which make a loud popping sound when opened. The cans are resealable aluminum bottles; the body of the bottle was similar to that of a standard aluminum can, but the top had a twist-off aluminum cap with a plastic gasket liner, and in smaller "Quick Fix" cans ( single-use pull-tab aluminum cans, similar to those used for Red Bull) and "battery" cans ( resealable aluminum cans with the same twist-off top as the battery bottles). The Jolt Cola website claimed that the "Quick Fix" sizes were available at establishments that serve "adult beverages," for use as a mixer. The flavors of Jolt offered were also changed. Flavors offered were Cola, Blue Raspberry, Cherry Bomb (cherry cola), Silver (lemon-lime), Wild Grape, Orange Blast, Passionfruit (featuring a yellow can) and Ultra (a diet drink with Splenda as its artificial sweetener alongside guarana, ginseng, taurine, and vitamin B complex).
