The CSL is still happening too.
BMW M cars are some of the most capable performance cars around, and have earned a reputation amongst car lovers as fierce performers. BMW's current range of proper M cars is the most diverse it has ever been, and the G80 BMW M3 and G82 BMW M4 are two of the best. BMW loves coming out with hardcore versions of its already capable M cars, with the M5 CS being one of our favorites at the moment. There have already been reports that BMW will revive the CSL nameplate for the M4, which will be lighter, lower, faster, and RWD only. But that isn't all that's planned. According to BMW Blog, the CSL will soon be joined by CS versions of both the M3 and M4 as soon as 2023.
The M3 and M4 CS are expected to follow in the footsteps of the currently available M2 CS and M5 CS, both of which are slightly more powerful, weigh less, and offer more precise handling. There's currently very little info on the two new CS models, but according to BMW Blog, both cars will be all-wheel drive and will be exclusively available with automatic transmissions. This might come as a disappointment to some, but we needn't remind BMW fans of how good the automatic M3 is, and how deliriously fun the AWD M5 CS can be in the bends.
The CS versions will likely have more power than the current 510 horsepower of the M3/4 Competition, but less than the rumored 550-hp outputs of the CSL.
These two cars will most likely share the exact same specs, with weight and stiffness only differing as a result of the two- and four-door layouts of the donor 3 and 4 Series. In the same vein as the M2 CS and M5 CS, these models will likely be the best distillation of what these cars can achieve with a road-biased nature. Their availability will be limited, too, as has been the case with all CS models previously, which were only produced for a single model year.
