Sonic Team is integrating extreme sports, high speed racing, and head to head battles in this new Sonic-themed racing title.

Dr. Eggman has thrown down the gauntlet, calling out Sonic and friends to join his World Grand Prix. But, just what is the egg-shaped genius really planning? And who are the legendary riders known as the Babylon Rouges that beat Sonic to the signup? At unparalleled breakneck speeds, you'll catch the turbulence air stream of your board-bound opponents and blaze past them while busting out wild stunts and tricks. Take full advantage of your characters' talents in Speed, Power, or Flight and challenge up to three friends to find out who really is the fastest rider in the world!
