BMW's super sedan is getting the hardcore CS treatment for the first time.
The BMW M5 was recently given a refresh for the 2021 model year with updated styling and improved tech. As part of the update, the M5 was fitted with a larger kidney grille, albeit nowhere near as massive as the grille gracing the new BMW 4 Series and the next-generation M4, which will debut this month.
BMW didn't extract any more power from the M5's 4.4-liter twin-turbo V8, but then this super sedan is hardly underpowered. In the range-topping M5 Competition, the twin-turbo V8 generates 617 hp and 553 lb-ft of torque - that's supercar levels of power in a family-sized sedan.
If, however, you want more power to play with, spy photos and videos have confirmed that BMW is cooking up a hotter M5 CS. This will be the first time the M5 has been given the hardcore CS treatment, joining its smaller M2 CS, M3 CS, and M4 CS siblings.
In this new spy video, two M5 CS prototypes can be seen getting a thorough workout at the Nurburgring. BMW has tried to disguise the front and rear fascias with familiar camouflage, but there are some noticeable differences that set the track-focused CS model apart including a unique grille and a new front lip spoiler. Unlike previous prototypes, the M5 CS has been fitted with a unique trunk spoiler, suggesting that development has progressed since our last sighting.
It also sits lower to the ground and rides on track-tuned suspension for even sharper handling, helping it remain composed during its run at the Green Hell. Naturally, the M5 CS will have more power and less weight than its standard siblings. Nothing is official yet, but BMW is expected to extract 641 hp from the twin-turbo V8, which is 24 more ponies than the M5 Competition.
With the new M3 and M4 debuting this month, there's a good chance the M5 CS will break cover later this year. Also expect production to be extremely limited since the M2 CS is limited to just 2,200 units. As for pricing, the hardcore CS will inevitably have a higher price tag than the M5 Competition, which starts at $110,000.
