According to this article on Active.com sports drinks hydrate you better than water, for three reasons:

1. Fluids are absorbed into the bloodstream faster when their composition closely matches that of body fluids such as blood. Sports drinks do this.
2. Sports drinks contain sodium, and other nutritents which help your body regulate fluid balance.
3. The sodium in the sports drinks simulates thirst, which makes it easier to drink more of it, than water.

Basically the sodium does a lot, and they recommend sports drinks with high amounts of sodium (at least 15 mg of sodium per ounce).
