BMW has proclaimed the 2022 M5 CS Sedan, with 627 horsepower and 553 lb-ft of torque, to be the quickest and most powerful BMW production vehicle ever produced, with a claimed 0-60 time of 2.9 seconds and a top speed of 190 MPH. It will arrive in the U.S. in the second half of 2021.
Having recently updated the M5 for 2021, the M5 CS adds more power, performance, and all-important interior appointment exclusivity, and is 230 pounds less than the M5 Competition. Liberal use of CFRP materials boosts the power-to-weight ratio of an already-high M5, since the M5 CS’ S63 4.4-liter M TwinPower turbo V8 only netted 10 HP more than the M5. The torque band is more impressive, with 553 lb-ft from 1,800 to 5,950 rpm, wider than the M5 Competition by 90 rpm. Redline is 7,200 rpm, with high-pressure, direct fuel injection, liquid-to-air intercooling for the twin turbos, and an oil system with two pumps.
