Here is literally everything in the first Mario Kart 8 DLC pack

A lengthy video explains it all

We’ve seen clips of the Mario Kart 8 DLC, but this new walkthrough video from Nintendo shows off everything in all its glory. All three characters (Tanooki Mario, Cat Peach, Link), four vehicles (Blue Falcon, B Dasher, The Master Cycle, and Tanooki Buggy), and eight tracks.

The video really shines in explaining every single stage, and gives you a great look at the entire layout, as well as some of the track gimmicks. When all is said and done, I think this may be my most played Mario Kart game ever.
