The BMW M3 CS will share many components with the M4 CS
According to the German luxury marque, the BMW M3 CS will share many components with the M4 CS including the carbon front splitter, rear diffuser, lip spoiler, GTS's seriously cool OLED tail lamps as well as some tweaks of the cabin. Particularly, we must mention the 454 hp version of the well-known twin turbo 6-cylinder S55 engine. With this figure, the M3 CS would be the most powerful series production M3 of all time.

Some reports claim that the BMW M3 CS is able to lap the Nürburgring Nordschleife in less than 7 minutes and 40 seconds with the help of ultra-high-performance Michelin Pilot Sport Cup 2 tires and a new chassis.
The BMW M3 CS is expected to enter the market in the spring of 2018 and it will be the last version of the existing F80-generation M3.
