Mercedes-AMG is not messing around. The German automaker's Formula 1 team is currently dominating every race it enters, so it is about time that the road cars achieve the same level of dominance. Enter the 2021 AMG GT Black Series, the most hardcore entrant into the AMG lineup since the SLS Black Series from 2014. According to Fastabast Taxi Experience, a Nurburgring taxi service, the AMG GT Black Series can do more than just sit in collectors' garages. It will soon claim the Nurburgring production car lap record.

Fastabast previously told CarBuzz several key statistics about the car before it was revealed, including the price, power, and rarity. The company will have a GT Black Series in its fleet so you can book a ridealong with a professional racecar driver.

As previously reported, the AMG GT Black Series clocked a six-minute 58-second time in the final stages of testing, which is much quicker than the AMG GT R's time of 7:10:92. Not content with this lap time, AMG then went on to tweak the aerodynamics of the car, as seen in these photos. There is some non-production bodywork, including a wider, GT3-style splitter that was fixed and supported by two belts.

With the more aggressive aero and non-production accessories, the GT Black Series allegedly lapped the Nordschleife in around 6:40. And according to Fastabast, the stock 4.0-liter twin-turbo flat-plane crank V8 can be tweaked to produce an additional 120 to 150 horsepower, increasing output from 730 to around 850 hp.

If accurate, AMG could steal the lap record crown away from the Lamborghini Aventador SVJ, which set a time of 6 minutes, 44.97 seconds. A lap time under 6:40 could be entirely possible and would be a staggering achievement for a front-engined car with rear-wheel-drive, taking the record away from a mid-engined supercar with all-wheel-drive. Of course, it is unclear if AMG's changes to the prototype will be made available on the production car, so it remains to be seen if this lap record can be official.

Perhaps Mercedes could eventually offer these aero and power upgrades as part of a track pack or Ring Edition, which would legitimize the lap time. If these minor changes to the car are enough to take a Nurburgring lap record, we see no reason why the company wouldn't offer them to customers.
