BMW has lifted the veil on its most powerful M model yet produced claiming a powerput of 631bhp for the new BMW M5 CS.

That’s around 10 more horses compared to the outgoing model from a 4.4-liter gasoline V8 with M TwinPower Turbo developing maximum power at 6,000rpm and peak torque of 553ft-lbs is produced between 1,800rpm to 5,950rpm. Thanks to the automaker’s motorsport experience, the engine can rev safely to 7,200rpm.

Also engine characteristics can be altered at the touch of a button from the basic EFFICIENT mode to SPORT and SPORT+, the latter two further quickening the engine’s response to accelerator movements. Equipped with the M Steptronic transmission with Drivelogic, the BMW M5 CS claims a 0 to 62mph sprint time in 3 seconds. The special edition needs just 10.4 seconds to reach 124mph from rest and is electronically limited to a top speed of 189mph. Despite the hypercar performance, the car claims combined fuel consumption of 25mpg (21mpg US) and CO2 emissions of 257g/km.

To cope with the power output, the BMW M5 CS will be sold with carbon ceramic disc brakes as standard. The six-piston fixed-caliper units at the front and single-piston floating calipers at the rear sport the M logo and are painted in Red with a Gold finish available as an option. These ceramic brakes are 50.6lbs lighter than the M Compound brakes on the BMW M5 Competition model and claim better performance, further improved fade resistance and still higher thermal stability. UK prices start from around £140,780 ($191,678) including taxes.
