2021 BMW M5 CS’ Output Allegedly Confirmed At 626 HP, Easter Egg Hints At Nurburgring Record

BMW has yet to unveil the M5 CS, yet parts for it have already popped up for sale online.

Not only that, but the more track-focused variant of the super executive sedan was also subjected to a fast lap of the Hockenheim-GP by SportAuto’s Christian Gebhardt, and as usual, the run was filmed from the cockpit.

We’ll get to the lap time in a moment, but first, the YouTube channel claims to know the exact output and torque produced by the twin turbocharged 4.4-liter V8 in this variant of the car, which is 635 PS (626 HP / 467 kW) and 750 Nm (553 lb-ft).

If true, then it is only 10 PS (10 HP / 7 kW) more powerful than the 2021 M5 Competition, which goes from 0 to 100 km/h (0-62 mph) in just 3.4 seconds, as the torque is identical in both models.

Now, let’s get back to the video, which shows the new M5 CS completing the course in 1:53.6, on 20-inch wheels, shod in 275/35 front and 285/35 rear Pirelli P Zero Corsa tires. For reference, the M5 Competition posted 1:54.2 in the hands of SportAuto earlier this year, whereas the Mercedes-AMG GT 63 S did a 1:53.4, according to FastestLaps, one tenth of a second slower than the Porsche 992 Carrera S.

Further down the chart, we find the 991 GT3, 718 Cayman GT4 and Jaguar XE SV Project 8, all of which were clocked at 1:53.9, and the 911 GTS and Chevrolet Corvette Grand Sport, with 1:54.0 and 1:54.1 respectively.

On a different note, the pre-production M5 CS depicted on film below had the Nurburgring Nordschleife map embedded in the headrests – could this mean that the record set by the Mercedes-AMG GT 63 S is already in danger?
