The Ultimate Black Series: 1066 HP AMG GT Black Series R3

THE WORLD'S MOST POWERFUL AMG GT BLACK SERIES IS HERE!

Loaded with motorsport derived solutions, the 2021 AMG GT Black Series is arguably the most track focused road vehicle from Mercedes-Benz AMG since the (homologated) street version of the CLK GTR in 1998.

Continuing the Black Series legacy from where the 2013 SLS Black Series left off, the AMG GT Black Series satisfies the high demand for track-oriented machines built for Club Racing. Lighter and faster, with wider track width, revised body work, larger grille, integrated air extractors within the hood and front fenders, manually adjustable front splitter, and the massive dual-plane rear wing are derived from AMG’s successes with the GT -chassis in GT3 and GT4 racing. 

Track derived performance and racing heritage: AMG GT 3 and CLK GTR at RENNtech 

In Europe the Black Series is offered with track driving options such as a rollbar, four-point seatbelts for driver and passenger, and a fire extinguisher, upgrades that RENNtech has been quick to introduce to the North American market.

RENNtech’s Roll Bar is made to order at their Head Quarters in Stuart, FL, and can be color matched to the vehicle and fitted with Sabelt or Schroth harnesses. The all new RENNtech Track Series forged high-performance aluminum wheels were designed specifically for the AMG GT -series (C/R 190 chassis) and offer owners a track focused and stylish alternative to the OEM wheels.

On the power side, RENNtech’s Hand Held ECU Tuner  instantly produces an additional 99 HP and 95 LB-FT, bumping the AMG GT Black Series up to 843 HP and 739 LB-FT.  If that is not enough, the R3 -upgrade delivers an mind-blowing 1066 HP and 831 LB FT running on 93 octane pump gas, making the AMG GT Black Series RENNtech R3 the most powerful Black Series in the world. 

At the heart of the R3 -upgrade is a set of larger and more capable Turbo’s, a set of Stainless Steel Downpipes, Blow Off Valves, and BMC Airfilters for improved exhaust sound and flow. To control the power increase, RENNtech has developed a TCU- tune (Transmission Control Unit) for faster and more firm shifts while increasing the torque capacity of the Mercedes-AMG 7-speed dual clutch transmission. The addition of the Stainless Steel Downpipes and Electronic Valve Module (EVM) improves the sound of the M178 V8, and fills the cabin with a raw and unrestricted sound punctuated with the occasional down-shift crackle. 

Four generations of RENNtech Black Series; AMG GT, SLS, SL, and CLK

Acceleration and throttle response is fast throughout the entire powerband, restricted only by the amount of open road and grip from 335 wide Michelin Pilot Sport Cup 2 R rear tires.

Launching the R3 from a standstill with ESP off and TC settings dialed in, the car rips at the ground like a beast, roaring to 60 mph in 3 seconds or less. Rolling at 75 mph and flooring it, the R3 makes an immediate downshift and whips the tach toward the 7,200 RPM redline without lag. Hold it, and the AMG GT will hit 150 mph in 5^th gear before continuing a relentless thrust toward the 219 mph (hypothetical) top speed like a fighter jet.

The result is an AMG GT Black Series where all parts have been improved in the name of driving performance. Under normal driving conditions around town the RENNtech R3 handles easy and is as compliant a GT C or GT R. Push it and the power arrives like artillery fire, heightening all senses and delivering an exceptionally engaging driving experience.

The R3 -upgrade is now available through RENNtech and official dealers across the United States, Europe, and Middle East. 

RENNtech is the leading performance tuner of AMG Black Series.

Introducing RENNtech Track Series Forged Wheels

AMG GT R with RENNtech Track Series 19 x 10" front and 20 x 12" rear wheels with Satin Titanium finish.

RENNtech RTS Forged Aluminum Wheels are the latest addition to a legendary line of RENNtech performance wheels.

It all starts with an idea: The right wheel for the right situation. RENNtech Track Series wheels exemplify RENNtech's philosophy of bringing Motorsports Technology to the Streets and were created to be the perfect wheel for performance and track driving.

RENNtech's product development team set out to deliver a track-oriented, light weight forged aluminum wheel featuring innovative technology and sophisticated design. Engineered for rigorous track use, RTS wheels are packed with functional design elements for improve structural integrity and maximum weight reduction. The refined design aesthetic follows the current Mercedes-AMG design language with visual cues to pre-merger AMG, making the RTS a perfectly balanced wheel for driving on track and the streets.

Initial Design Concept: Inspired by AMG heritage

Design Development: 3d CAD model

Design Review: 3d printed prototype

Engineering: Finite Element Analysis (FEA)

After confirming the technical viability, several design concepts were explored, refined, and translated into CAD to create the first 3D printed prototypes for visual reviews. From these prototypes, combined with stringent engineering analysis of the CAD models, including Finite Element Analysis (FEA) software validation before the final production version emerges for fitment and real-world testing.

Rigid Spoke Tracers were incorporated into the spoke profile for improved structural integrity while reducing the overall weight of the wheel. A Reinforced Inner Rim Flange was integrated to better withstand wheel deflection / deformation under high load situations, resulting in improved driving performance and consistency on track.

Aluminum Wheel Casting vs. Flow Formed vs. Forged

RENNtech has strategically partnered with industry leaders Titan 7 Wheels for development and production of the RTS wheel.

"Titan 7's extensive experience in manufacturing track focused wheels combined with their forging expertise and their complete in-house production gives us a high degree of control in the production process. This way we can deliver a wheel of the highest quality and consistency that RENNtech is known for, and our customers have come to expect." said Hartmut Feyhl, President RENNtech Inc.

Each wheel starts out as a solid cylinder of aircraft grade 6061 aluminum. These cylinders are pressurized with 10,000 tons of pressure to improve the grain structure and overall properties of the aluminum to obtain the wheels initial shape and dimensions. The result is a CNC machine ready forging which features no porosity and a densely organized micro structure for an incredibly strong and lightweight wheel.

RENNtech Motorsports on Podium in 2022 SRO Season Opener

Chirs Gumprecht finishes 2022 SRO GT America Sesaon Opener with a 2nd Place in the GT4 class.

Sharing track time with the NTT Indy Car series at the St. Petersburg Grand Prix, RENNtech Motorsports fielded two Mercedes-AMG GT4 racecars on the narrow streets of St. Petersburg, FL.

Chris Gumprecht returned to GT4 racing behind the wheel of the C.G. Racing #79 AMG GT4, and new to the RENNtech Motorsports Team, Custodio Toledo, making his GT4 racing debut in the RENNtech #89 AMG GT4.

Starting P7 in class for Race 1 on Friday, Chris Gumprecht avoided a multi car crash on lap one and moved into P4. Gumprecht was able to hold his position until the eventual race winner, Marko Radisic, in the BMW M4 GT4 made an overly aggressive passing attempt. Taking a hit to the left rear corner, Gumprecht spun around and subsequently lost several positions. After settling back into the race Gumprecht recovered for a P8 finish.

Cutodio Toledo delivered an impressive performance in his sportscar racing debut. Racing in the RENNtech #89 AMG GT4, Toledo was unfazed by the multi car crash while avoiding faster GT3 traffic, settling into the race and consistently improving his lap times, finishing his first GT4 race in P11.

Starting P8 in Race 2 on Saturday, Chris Gumprecht was poised to make up for the mishap in Race 1. With a great start, Gumprecht leaped into P3 by Turn 2 and settled into a great race rhythm. Continuously improving his lap times, Gumprecht set his fastest lap time on Lap 23 of 30 while closing the gap to Derek DeBoer's Porsche Cayman GT4 sitting in P2. With relentless pursuit Gumprecht was able to capitalize on DeBoer's mistake in Turn 1, moving into P2 on Lap 25. Gumprecht defended his position finishing the race behind the safety and claiming his first podium of the 2022 season.

After Friday's successful debut race, Custodio Toledo continued to impress in the second race of the weekend. Starting P12 in GT4, Toledo avoided the starting mayhem in Turn 1, skillfully handling the AMG GT4 through the tight streets of St. Petersburg. Constantly improving on his laptimes, Toledo drove a mistake free race finishing his debut weekend in P11.

RENNtech Motorsports will be back in action at the second round of the SRO - North American season in Sonoma, California, April 15 -17, 2022. Sonoma Raceway will also host the season opener of the highly competitive Pirelli GT4 America season. The race weekend will feature two races in the one-driver 40 minute Sprint style an two races in the two-driver 60 min SprintX class.

RENNtech Engineering
Stratasys F770 3D Printer - First in Florida

RENNtech Engineering has utilized 3D printers to create prototypes, jigs, and parts for over two decades. Our most recent addition to the printer lineup is the Stratasys F770, which is capable of printing large parts over 3 feet in length / width and is the first one of its kind in the State of Florida.

The use of 3D printing helps lowering cost and lead time of production parts though verifying concepts and fitment, and shortens the time-to-market for new products. This allows RENNtech to introduce new products to the market at competitive prices without compromising design, quality or time.

“3D printing has always been a great tool for rapid prototyping, but there’s a common problem of build volume being too small. With the F770 is capable of producing large parts in one or two pieces instead of five or six. This will enable us to design, and prototype printed parts we have not attempted before; like hoods, widebody kits, and doors. The upcoming years will be very imaginative and exciting, I cannot wait to see what we come up with. “ – Connor Salley, Engineer RENNtech

The Stratasys F770 uses the highest quality ABS and ASA materials which can be used for large size prototypes or lightweight production pieces. The first production piece from the Stratasys F770 will be the Eurostyle Bumper Plate designed for the C257 CLS -chassis.

Designed in house, the Eurostyle Bumper Plate is designed to eliminate the unsightly American “bumperette”, replacing it with a form-fitting insert for a sleek look. After printing, the part will be test-fitted and then finished in either primer or gloss black before made available for our customers.

Other performance products that benefit from 3D printing at this scale include our carbon fiber Aero products. With prototype Aero parts we can test fit and visually inspect parts designed in CAD before moving to carbon fiber manufacturing, a valuable pre-production feature of 3D printing which benefits the end user – the Mercedes-AMG Performance enthusiast.

2015 SEMA AMG GT S RENNtech : The foundation for AMG GT performance.

 

2015 SEMA AMG GT S RENNtech:

The foundation for AMG GT performance.

Since we converted our first customer car into an official AMG vehicle back in 1989, our development vehicles have represented the pinnacle of contemporary automotive engineering, design, and customization. Over the past 33 years, dozens of these historically significant vehicles have been featured on magazine covers, news articles, videos, blogs, and documented in the RENNtech 30^th Anniversary Limited Edition Calendar.  Among these is the one-off custom 2015 AMG GT S which served as RENNtech’s development vehicle for most of the AMG GT -series performance upgrades. 

1991 RENNtech E60                                                       2008 GLK Pikes Peak Concept                                      2011 C74 Konzept Widebody

Performance development begins with our Engineering team recognizing a deficiency and presenting ideas on how to improve the performance of the vehicle. From that point on the vehicle typically undergoes several stages of R&D and thousands of hours of engineering, design, testing, and marketing. 

After winning the Mercedes-Benz Mission: Metris Van Challenge at the 2014 SEMA Show with the DJ Van, RENNtech was invited to compete in the Optima Ultimate Street Car Invitational at the 2015 SEMA Show in Las Vegas.

With an extremely short timeline of only 7 months from receiving the GT S, RENNtech's engineering team unveiled the fully RENNtech'd AMG GT S in November. With a remapped ECU tune, Downpipes with Sport Cats, Coil-over Suspension, 3pc Forged RPS-10 Wheels, and a RENNtech designed all-around aerodynamic package, consisting of Splitter, Diffuser with Exhaust Tips, Rocker Panels and Adjustable DTM-Style Wing. With this spectacular feat of speed and execution, the RENNtech GT S stunned enthusiasts, the automotive media, and the Mercedes-AMG Tuning Industry.

Subsequently the GT S continued to serve as RENNtech's development car pushing the limits of power and performance of the AMG GT / S -series, resulting in the 731 HP & 633 TQ R3 -upgrade and hatching production performance upgrades for the global Mercedes-AMG GT Performance aftermarket.

Once the development vehicles have reached maturity, we make them available to the RENNtech community through our website. Many of our prior development cars have found their way into private collections, museums, and promotional vehicles for Mercedes-Benz. The one-off AMG GT S recently found a new owner on Bring A Trailer who will get to enjoy the fruits of our labor while we continue to develop the next era of Performance Without Compromise.
