The 2023 BMW M3 CS may not be one of the prettiest sedans out there, but it's certainly among the fastest. In fact, few other four-door cars dare to go up against Bavaria's latest Clubsport model, at least when it comes to straight-line acceleration. An unmodified example of the sporty saloon was taken to an unrestricted section of the Autobahn where it delivered supercar-like performance. In typical M fashion, it was faster than claimed.
BMW may say the M3 CS does 0 to 62 mph (100 km/h) in 3.4 seconds, but in reality, the limited-run super sedan will do the job in just 3.2 seconds. It needed 10.37 seconds to go from 0 to 124 mph (200 km/h), thus beating the official 11.1-second sprint time provided by the German luxury brand. It went on to complete the quarter mile in 10.86 seconds after doing 62 to 124 mph (100 to 200 km/h) in 10.37 seconds.
