The Atlanta-based company says it will test a "Sprite Select" and "Fanta Select" this summer that will have about half the calories of regular. The drinks will be made with a blend of sugar and other sweeteners, including Truvia and erythritol. The tests will take place in a limited number of stores in Atlanta, Detroit, Louisville, Ky., and Memphis, Tenn.

Scott Williamson, a spokesman for Coca-Cola, noted that there are no plans for a national rollout yet.

The new formulas will both have 70 calories per a 12oz. can. A can of regular Sprite by contrast has 140 calories and a can of regular Fanta has 160 calories.

Coca-Cola and PepsiCo have tried mid-calorie drinks in the past. In 2001, Coke rolled out "C2" and Pepsi in 2004 introduced its "Pepsi Edge." Both were taken off the market because of poor sales.
