BMW M5 CS with 626bhp is the most powerful M car to date
Powering the BMW M5 CS is the same 4.4-litre M TwinPower Turbo V8 that's been tuned to develop 626bhp @ 6,000rpm and 750Nm of torque between 1,800 – 5,950rpm. While the torque output is the same, it develops 9bhp more than the 2021 M5 Competition and 35bhp more than the standard M5.

The first-ever, limited-run BMW M5 CS will make its commercial debut in Europe sometime in Spring 2021.
When the 2021 BMW M5 & M5 Competition were unveiled in June last year, BMW was rumoured to be working on the first-ever and a more hardcore CS version of the M5. Those rumours have finally been laid to rest as the M5 CS has been revealed, with a colossal 626bhp on tap. Not only is it more powerful than the M5 Competition (617bhp), but it's also officially the most powerful BMW M model produced to date!
Powering the M5 CS is the same 4.4-litre M TwinPower Turbo V8 that's been tuned to develop 626bhp @ 6,000rpm and 750Nm of torque between 1,800 – 5,950rpm. While the torque output is the same, it develops 9bhp more than the 2021 M5 Competition and 35bhp more than the standard M5. An eight-speed M Steptronic transmission with Drivelogic, the M xDrive all-wheel-drive system with a full-rear bias '2WD' mode, a quad-pipe stainless-steel sports exhaust system and M Carbon ceramic brakes all are part of the standard kit.
To ensure the chassis can withstand the additional power, all four dampers and bearing springs of the front & rear axles have been re-tuned. Thanks to the extensive diet, the M5 CS can cross the 100km/h mark in just 3 seconds, 0.3 of a second quicker than the M5 Competition.
Coming to the changes under the skin, the M5 CS has lost up to 70kgs over the M5 Competition. This has been achieved by using super lightweight carbon-fibre-reinforced plastic (CFRP) for the M5 CS' bonnet, engine cover, intake silencer, ORVM caps, front splitter, rear spoiler and the rear diffuser. Inside, a new, fixed armrest cover replaces the conventional opening lid to save weight.
The M5 CS also comes with a couple of visual updates to set it apart from the rest of the M5 versions. The kidney grille housing, the 'M5 CS' badges on the grille and the 'M' gills on the front fenders and the boot lid are all finished in a bespoke 'Gold Bronze' shade, and so are the unique 20‑inch Y-spoke M forged wheels. Another big change is the revised bonnet that's sculpted and features twin air intakes. Plus, the L-shaped tubes of the BMW Laser headlights glow yellow instead of the standard white, a change that harks back to the GT race cars of yesteryear. Inside, there's plenty of 'CS' badging that can be found on the dashboard, the seats and the door sills (illuminated).
As of now, the M5 CS will make its commercial debut as a special-edition, limited-run model. However, it is likely to join BMW's CS model line-up as a series-production version 2022 onwards.
