This mammoth missile is seriously fast.
The BMW M5 has always been the subtle, supercar-slaying sedan that you can take to a business meeting, but when the boys and girls in Munich released the M5 CS, a lot of that tact went out of the window. With pumped-up bodywork and a 4.4-liter twin-turbo V8 tuned to deliver 627 horsepower and 553 lb-ft of torque, it's an absolute monster. Inside, its seats bear a graphic of the Nordschleife's outline, suggesting that Munich would be chasing a record at the Nurburgring. We've seen a prototype go around the track but are yet to learn if the super sedan has made an attempt at the record, but Sport Auto couldn't wait and decided to set its own time. Below is the timed lap, completed by the publication's test driver.
The M5 CS completed the course in 7:29.57, which is short of the Mercedes-AMG GT 63 S. That car currently holds the record (the Jaguar XE SV Project 8 doesn't really count in our book) at the Green Hell with an official time of 7:23.009 for the 12.8-mile layout and 7:27.8 for thee 12.944-mile layout.
However, it's worth noting that Mercedes-AMG's time was set by its own driver while the M5 CS here was piloted by Sport Auto's Christian Gebhardt, and it's safe to assume that a bona fide BMW test driver would be quicker thanks to being more familiar with the car. We can also see that the run was completed without the traction control turned off, and it's possible that a more confident, focused driver that doesn't take his or her hands off the wheel could get more out of the car.
With that being said, the difference between the M5 CS and the GT 63 S is still almost two seconds for the longer layout of the track, a big difference. As such, we wonder if BMW M has not posted a time around the Ring because it has egg on its face and can't beat AMG. Alternatively, it could be that BMW simply added the Nurburgring graphic as a throwback to the E34 Nurburgring Edition. Either way, Mercedes wants to assert its dominance in this segment and seems to be working on a hardcore version of the E-Class, called the E 73. Either way, we really want to know just how fast the M5 CS can get around the circuit and hope BMW releases its own attempt soon.
