BMW’s M Division is allegedly working on a more track-focused version of the F90 M5 LCI, which will be dubbed the M5 CS and will sit at the top of the range above the M5 Competition.

Prototypes have been seen testing at the Nurburgring and on the streets of Germany ever since last year, and if we were to take an educated guess, we’d say that it will premiere before the end of 2020.

This is also BMWBlog’s opinion, which claims to know other things about the car, such as the output and torque numbers, which should be in the region of 640 HP (650 PS / 478 kW) and 590 lb-ft (800 Nm). That would make it 25 HP (25 PS / 18 kW) and 37 lb-ft (50 Nm) more powerful than the M5 Competition, which does the 0-62 mph (0-100 km/h) in 3.3 seconds and maxes out at 189 mph (305 km/h) with the optional M Driver’s Package.

To enhance the tail-happy nature of the car, which will still pack the rear-biased xDrive all-wheel drive system tuned by the M Division, a tweaked limited-slip differential is expected to be offered. High-performance ceramic brakes with drilled discs should be optional extras, and the M5 CS is also understood to feature a CFRP roof and several aerodynamic upgrades, such as the deeper front apron, bigger boot lid spoiler and redesigned bumpers. Exclusive colors and wheels, as well as ‘M5 CS’ badges inside and out, will also be part of the offering.

The German car maker is thought to limit the production number of the model, although it’s unknown yet how many will be made.

As far as the pricing is concerned, expect to pay more than $111,1000, which will be the official MSRP of the 2021 M5 Competition in the U.S., when it launches in August, with the quoted website stating that it will start at more than $120,000.
