According to a document posted in the forums of Bimmerpost, the return of the G80 BMW M3 CS eminent. However where the previous CS was rear wheel drive, it looks like this new CS will come with xDrive standard. And if rumors are correct will not be available with a manual.
The document below appears to confirm the 543 hp tune of the S58 along with the ALLR which is code for xDrive. What is unconfirmed is if BMW will offer the manual as they have previously. We know the current manual cannot handle more than 405 lb. -ft which will likely keep it off the options lists for new 2024 BMW M3 CS.
The 2024 BNW CS will likely debut late next year with a spring 2024 market launch. Prices and final specs should be available in the second half of 2023.
