The redesign of the karting circuit is close to completion.
This is Skye from Koni Entertainment. I have been working on this car model for the last few hours, about 2 hours have passed. It's modeled after a Volvo S60-R from 2001. The car in the game is a GT2 class car, with MEDIUM handling.
Furthermore, a classic racing circuit (my first ever circuit, a remake of it, pictured below) is in the works. It won't be featured in the story, it will be featured as a bonus stage.
If you complete the story mode, you get access to a new stage, simply titled BONUS. BONUS stage includes bits that are silly, such as racing airport vehicles or bits that couldn't fit in the story, such as tributes to other video games, racing drivers, etc.
