CURNO, Italy — From its creation way back in 1927, the Nürburgring has been used by the world’s most important manufacturers to put the strengths and flaws of their prototypes to the test. With a length of 20.8 km (19.9 mi) punctuated by 73 turns of every kind as well as many changes in slope and different surfaces, the Nordschleife is the most demanding test bench a car can face.
For good performance on this track – once also used for F1 – you need speed on the straights and the big turns, in changing direction and when braking as well as when accelerating. And you always need the utmost grip, since every tenth of a second lost on a turn can affect the final outcome.

All that explains why every car manufacturer wants to be able to boast of holding the Nürburgring Nordschleife lap record. It long seemed impossible for a road-going car to break the 7-minute barrier, but since the early 2000s it has been broken a number of times, with Lamborghini managing to clock 6’44’’97 in 2018.
Many experts thought that this time was to remain an unbeaten benchmark for a long time to come, but things took a different turn a mere two years later: Mercedes-Benz took to the track with the AMG GT Black Series in the expert hands (not to mention feet) of Maro Engel behind the wheel.
The result was a Nürburgring record time of 6’43’’61, more than 20 seconds less than Mercedes with the same driver in the AMG GT R Pro in November 2018. This fantastic improvement for the German manufacturer came courtesy of the 3982cc twin-turbo V8 engine, which ensures a power of 537 kW (730 HP) and maximum torque of 800 Nm. Mercedes engineers succeeded in packing all this into a weight of just 1,615 kg (1.78 t).
These thrilling figures lent the Mercedes AMG GT Black Series exciting performance on the Green Hell, which also came via tires, front and rear spoilers and of course Brembo brakes, which on the one hand mean shorter braking distances because of their constant performance and on the other improved dynamics and performance from the Mercedes AMG GT Black Series thanks to the low weight.
Innovative technology and solutions were essential to achieving this, such as the Brembo aluminum monobloc front calipers with 6 pistons and new DYATOM™ carbon-ceramic brake discs, developed by Brembo SGL Carbon Ceramic Brakes (BSCCB).
In addition to the characteristic light weight, performance and design that come from choosing aluminum over cast iron, Brembo front calipers can offer cars advantages connected with reduced residual torque, meaning enhanced performance that isn’t limited to braking alone.
Given the high loads generated by pistons pressing on pads, and to ensure the utmost rigidity and less deformation, the calipers are monobloc, billet-machined from a single block of cast aluminum. The use of several opposed pistons also allows for better distribution of force on the pads and more even wear on the friction surfaces.
