On Twitter today, Nintendo of America revealed Link's vehicle in the upcoming Mario Kart 8 DLC — the Master Cycle. The tweet said that it has "plenty of horse power." Because it's shaped like a horse… get it?
Link and the Master Cycle will be part of Mario Kart 8's first DLC, releasing this November. It also includes cat-suit Princess Peach, Tanooki-suit Mario, new tracks, and an F-Zero-inspired Blue Falcon kart. A second DLC is planned for May 2015, and it will include Animal Crossing's Villager, Isabelle from Animal Crossing: New Leaf, Dry Bowser, eight new tracks and four new vehicles.
