A few weeks ago, OPUS Automotive GmbH became the world’s first tuner of the Mercedes-AMG GT Black Series and have already achieved power levels of up to 1111hp.

OPUS is located close to the Nurburgring racetrack, in the same business park where racing teams and well-known vehicle manufacturers have settled. In fact, OPUS moved into the former test centre of Mercedes-AMG GmbH on Gottlieb-Daimler-Street.

Of course, it is still too early to speculate about lap times of the OPUS-modified GT Black Series. However, it should be noted that this is the fastest, street-legal, unmodified series production car on the Nurburgring Nordschleife. We couldn’t be more excited and can’t wait to hear more about the upcoming laps.

The so-called “OPUS Binary Editions”, with 1111 and 1001 hp, will be released for sale after hard testing on the dynamometer, on the road and undertaking countless laps in the green hell of the Nurburgring and other racetracks. The expected release date is June 2021.

With the currently highest power-stage, the OPUS-modified GT Black Series will surpass the AMG ONE by 57 hp, which has a system output specified as 1054 hp.

One might get the idea that this is a relatively high amount of power for a rear-wheel drive vehicle. But there is a solution:

At all power levels OPUS limits the torque to the “bare minimum” for best traction as well as the drivetrain-longevity. In combination with the ex-works sophisticated aerodynamics, the performance is by no means over-portioned. OPUS also promises characteristics similar to an NA engine with a linear performance curve for all performance levels, i.e. increasing power in parallel to the rpms.

If these numbers seem too high for you, you just have to wait until mid-April, when the performance kits with 825 and 920 hp will be available.

With the exception of the 825 hp stage, which is done purely via a software-remap of the engine and transmission control unit, all performance kits contain further, sometimes very extensive changes to the hardware. These range from modified turbochargers and a gearbox reinforcement to a revised engine including special forged pistons, reinforced connecting rods, machined cylinder heads and a completely modified fuel system.

The packages above will be rounded off in just a few months by super-light wheels and aerodynamic add-ons, but OPUS has decided not to provide further details of this yet.

So much for the information about the tuning components for the true shooting-star GT Black Series.

The name OPUS may raise the question ‘Who is this supposedly new star in the Mercedes tuning segment?’

OPUS is a newcomer only by name. The development team around the managing director, automotive engineer Lukas Domogalla, is one that has been active in the industry for 20 years. The team has worked as a sales representative for a well-known American company as well as an independent development and test centre.

“The already different market requirements demanded an adjustment of the business model of our company with the current global crisis,” says the OPUS managing director. “Last but not least, standing still equals regression and change is the only constant in life. This is why we are very much looking forward to continuing to set benchmarks in the industry after the restructuring.”

Especially with regard to the AMG GT and the GT R, the Nurburgring team probably has the most in-depth expertise in the world and will certainly continue to demonstrate its superiority, not least with the latest top model from Affalterbach.

After all, the team from Meuspath is referred to as the “Home of the AMG GT” for a reason.

“By defining the word ‘opus’ as an artistic, musical and scientific work, the direction of the coming products is predetermined. We are always concerned with the best possible interaction between the individual vehicle components, which result in a ‘symphony’ solely when precisely coordinated with one another,” continues managing director, Lukas Domogalla.

Speaking of music, not only fans of the AMG GT Black Series will have noticed that the new noise regulations allow the new 4.0-liter V8 biturbo with flat crankshaft, internally known as the M178 LS2, to give at most a gentle hiss when delivered from the factory.

For this, too, OPUS has a solution: For the usage on the racetrack or outside of Europe, newly developed downpipes with sport cats will be available from mid-April 2021. The installation of which means that the standard particle filter is no longer required.

To round it off, there is an electronic flap control system called EFC (ExhaustFlapControl) ready for sale, which allows the standard exhaust flaps to be actuated using a remote control as required.
