2019 BMW M3 CS - Its release also signaled the end of the line for the current generation of the 3 Series, code name F30, soon to be replaced by an all-new car, code name G20, to be introduced at the 2018 Paris Auto Show. That qualifies the M3 CS as one last brilliant flash of speed, as it is the fastest and most dynamic as well as the last variant of the F30 3 Series.
