2021 BMW M5 CS confirmed! V8-powered super sedan scores more power, less weight to take down Mercedes-AMG E63 S and Audi RS7

BMW has officially confirmed a CS version of its M5 super sedan, which will bump power from its 4.4-litre twin-turbo petrol V8 engine from 460kW in the M5 Competition to 467kW.

Due to be revealed in full later this month, BMW Australia is still yet to confirm whether the top-dog M5 will land in local showrooms, but given the CS grade of the M2, M3 and M4 were available Down Under, we expect the latest ‘Competition Sport’ model will arrive sometime in 2021.

Torque remains steady at 750Nm in the M5 CS, but weight is down 70kg thanks in part to the use of a carbon bonnet and front bucket seats, as well as a four-seat layout.

Other changes include bespoke Pirelli P Zero Corsa tyres measuring 275/35 up front and 285/35 in the rear, which should provide better grip in the corners and could launch the M5 CS from zero to 100km/h quicker than the M5 Competition’s 3.3-second figure, and a retuned suspension set-up.

Though not yet confirmed, the eight-speed torque converter automatic transmission and rear-biased xDrive all-wheel-drive system should carryover from the M5 Competition to M5 CS.

From the outside, the M5 CS adopts gold-bronze highlights to contrast against its matte-grey paintwork, which is applied to the front grille surround, 20-inch wheels and fender strakes.

The M5 CS also adopts carbon ceramic brakes and red-painted brake callipers, eschewing the signature M blue.

Also, as a nod to its motorsport ambitions, the M5 CS will score yellow headlights and a more pronounced bootlid spoiler.

If the M5 CS does land in Australian showrooms, expect it to wear a higher price than its M5 Competition sibling, which starts at $246,900 before on-road costs.
