Internal Material
On July 24, 2020, a vast amount of source code from Nintendo's early consoles surfaced as well as prototypes and assets from games such as Yoshi's Island, Super Mario World, The Legend of Zelda: A Link to the Past and more.
The leak included Super Mario Kart's source code with previously unseen assets, tools and probably everything the development team used back then in the early 90s.

Early Donut Plains 1
These photos were published in a CES '92 article in the October/November 1992 issue of the Italian magazine Computer + Videogiochi (CVG). The layout is very different than the final, and the track is an early version of Donut Plains 1. It should also be noted that the player has 5 lives, which is impossible to have in the final.
The August 1992 issue of the German magazine Video Games showed another shot of the early track, as well as early versions of Bowser Castle 3 and a Ghost Valley track.
Issue 38 of Nintendo Power shows two more shots of the early Donut Plains 1 track as well as an early character select screen, which appears to have a different order than the final, and an early Choco Island 1, which is missing the puddles on the bottom portion of the track.
These screenshots appear to be from the April 13, 1992 prototype.
Seen on the back of the North American and European package for the game is a screenshot showing a later version of Donut Plains 1. The layout appears to be identical to the final, except that the walls inside the track have no diagonal sections. This screenshot appears to be from the May 18, 1992 prototype.
Early Battle Course 3
Issue #12 of the Italian magazine Consolemania shows an early version of Battle Course 3, which is themed after Choco Island rather than Vanilla Lake.
