2022 BMW M5 CS: Meet the fastest and most potent M car Alvin Reyes - Jan 27, 2021, 5:29am CST We knew beforehand the 2022 BMW M5 CS will literally blow away the competition. BMW went to Instagram before the new year and unveiled some juicy tidbits on its latest M5 CS ‘Competition Sport’ sedan, promising more power, less weight, and maximum driving enjoyment. The new BMW M5 CS is the fastest and most powerful iteration of the seventh-generation 5-Series. It has the same 4.4-liter twin-turbocharged V8 engine as a standard M5 and M5 Competition model. But with two oil pumps, a liquid-to-air intercooler, and high-pressure direct injection, the M5 CS produces 627 horsepower and a healthy 553 pound-feet of torque, ten horses more than the bonkers M5 Competition.
