Rumoured LEGO Racing game is a collaboration with 2K called LEGO 2K Drive
The LEGO Group has apparently joined forces with 2K Games to produce a LEGO-based racing game. The game is apparently titled LEGO 2K Drive and is being developed by Visual Concepts. LEGO 2K Drive is said to be an open-world racer and probably came about due to the success of the Forza Horizon 4: LEGO Speed Champions expansion which launched in 2021 on Xbox and PC.
The LEGO Group hasn't confirmed the project, but it sounds as though they are on the cusp of an announcement.
