Mountain Dew Kickstart will come in two flavors, Orange Citrus and Fruit Punch, and will be available in stores starting February 25, 2013.
The new morning soda contains relatively low calories versus a regular can of soda at 80 calories per 16-ounce can. The 16-ounce can size is more commonly found in energy drinks rather than soda, which might be what they're going for.
The concept is similar to Mountain Dew A.M., which is offered at Taco Bell restaurants that serve breakfast.
