Ladies and gents, feast your eyes upon the all-new BMW M5 CS, the newest and baddest 5 Series in (M)town. But it isn’t just another M5 variant, oh no. Because the M5 CS is now the most powerful and fastest-accelerating production BMW vehicle ever made.
Joining the BMW M2 CS in the ranks of models carrying the coveted “Clubsport” title, the all-new M5 CS super-sedan turns its performance dial all the way up to 11, probably obliterating any sense of comfort and day-to-day liveability at the same time. We’re not complaining, though.
So how does BMW make the already-incredible BMW M5 Competition even faster? Well, the answer, as always, is more power and less weight, plus a little dusting of motorsports-inspired styling elements for good measure.
On the “more power” front, the BMW M5 CS gets treated to a reworked 4.4-litre twin-turbocharged V8 engine, now generating 635 hp (+10 hp) and 750 Nm of torque, the latter unchanged from before.
Pair that to the eight-speed Steptronic M automatic gearbox and a reprogrammed M xDrive all-wheel drive system, and the M5 CS completes the 0-100 km/h sprint in just 3.0 seconds. Continue to keep your right foot pinned to the floor, and you’ll arrive at 200 km/h in 10.3 seconds, onward to a top speed of 305 km/h.
Alongside increased performance, the BMW M5 CS also gets a redesigned oil pan with an additional sump and indirect charge air cooling, as well as more rigid engine mounts, which helps achieve a smoother transmission of power to each wheel, according to BMW’s performance division.
The suspension has also been fitted with firmer dampers and 10% stiffer springs which reduces the ride height by 7 mm, working in conjunction with the stiffer tow-link ball-joint mounts, stiffer rear sway bar, standard 20-inch wheels and a no-cost option Pirelli P Zero Corsa tyres, as well as standard M carbon ceramic brakes to further slice away lap times. There’s no need to explain why the M5 CS has the Nordschleife etched onto the seats.
Thanks to an intense weight-loss programme, the BMW M5 CS weighs 70 kg less than the Competition variant. BMW says that this was done by reducing the amount of sound-deadening material, alongside an ostentatious amount of carbon fibre parts all round. And we mean that quite literally – there’s carbon fibre almost everywhere.
The roof, bonnet, splitter, spoiler, diffuser, and mirror caps have all been replaced with carbon fibre parts, and even the M Sports seats have been jettisoned in favour of the lighter M carbon fibre bucket seats. Heck, even the gearshift paddles are made of carbon fibre. Other lightweighting measures include the deletion of the rear middle seats (replaced with two individual seats), and a reworked centre arm rest without a stowage compartment.
To distinguish the all-new BMW M5 CS from its “regular” counterparts, the super-sedan gets a special “Gold Bronze” finish on its kidney grilles, badging, gills surrounds, as well as the 20-inch staggered M forged wheels. The massive brake callipers can also be optioned with the same bronze finish, but comes as standard with a coat of red paint.
The carbon fibre bonnet gets two additional hood scoops dressed with exposed carbon fibre and a power bulge, while the light signature within the BMW Laserlight headlights gets a yellow tint as a nod to BMW’s GT race cars.
In addition to the normal selection of M5 colours, the CS will also be offered in three unique BMW Individual colours: Brands Hatch Grey metallic, Frozen Brands Hatch Grey metallic and Frozen Deep Green metallic, the latter of which is can be seen in these photos.
The BMW M5 CS will go on sale in spring of 2021 for EUR180,400 (RM886k) in Germany and other large markets, with production slated to begin around March, limited to one year only.
