RENNtech returns to GT4 America for 2024 Season

 Michael Auriemma Returns to RENNtech
Partners with IndyCar’s Matheus Leist
for Championship Chase! 

STUART, FL - After his debut season with RENNtech Motorsports in 2023, Michael Auriemma returns to race the #89 RENNtech AMG GT4 in SRO’s GT4 America.

The RENNtech #89 will move up to the Pro-AM class with Michael’s new codriver, Matheus Leist, for the 7-round, 13-race season. Making his GT debut at the age of 25, Leist comes with an impressive racing resume. Matheus previously raced two seasons in IndyCar as well as Daytona Prototypes in the IMSA Sportscar- Challenge. His invaluable experience at the highest levels of American racing elevates the team to championship contention. 

Michael Auriemma, Driver #89:
“Last year was a great experience after a ten-year hiatus. Now I feel like I’ve got the rust off and I’m ready to take a step forward. I’m excited to be back in the RENNtech car with a crew that feels like family and to be moving up to Pro-AM with a super talented co-driver.” 

Matheus Leist, Driver #89: 

“Last year I had the pleasure to work with Michael and RENNtech as a driver coach, and this year I’ll be stepping into the driver’s seat once again. I’m very excited to work with such a great group of people. I’m looking forward to 

the challenge and I can’t wait for the first race of the season.” 

Also under the RENNtech tent for 2024 is the previously announced addition of the OnlyFans #43 P1 Groupe AMG GT4. After one season in GT America, Alex Vogel joins the team to pair up with Matt Bell in the Pro-AM class of GT4 America. 

After two successful test at Sebring International Raceway during the Off-Season, RENNtech will start its two-car 2024 season effort with pre-season testing 
in Sonoma before the season opener in April. 

Hartmut Feyhl, Owner: 
“After only one podium in 2023, we as a team are fully committed and ready to make the needed investments to bring race wins and championship aspirations back. Having Michael back and pairing him up with a talent like Matheus is a big step in the right direction.” 

The 2024 season opener is once again at Sonoma Raceway in California on April 6. RENNtech’s hometown race has been moved to early May, before traveling to Austin, Texas. The round-three race at COTA is the endurance debut for GT4 America. Instead of the usual two one-hour races per weekend, a single three-hour race will determine the winner.
After the summer break, racing will start back up at VIRginia International Raceway and Wisconsin’s Road America. The September slot previously filled by Sebring has been taken over by Barber Motorsports Park. 2024 will mark the first time since 2016 that SRO-America races in Birmingham, Alabama.
The season finale will be held once again in Indianapolis in early October. 

2024 GT4 America Schedule:  April 5-7 Sonoma Raceway  May 3-5 Sebring International Raceway  May 17-19 Circuit of The Americas  July 19-21 VIRginia International Raceway  August 16-18 Road America  September 6-8 Barber Motorsports Park  October 4-6 Indianapolis Motor Speedway

RENNtech Builds World Record AMG GT63 S Edition 1

Is there a better way to celebrate the 35th Anniversary year than setting a new record?
Not if you are RENNtech.

The AMG GT63S Edition 1 is back - and faster than ever.

Early February 2024, the owner of Graphite Magno Edition 1 AMG GT63S that we first wrote about in June of 2023, sent us pictures of his new yellow graphics and custom magnesium wheels along with a enthusiastic note.

“👍WOW, this car you did for me is different than anything I’ve ever owned. I just took her out for a run and it did a 4.92 second 60-130 time. That’s more than a second faster than last May.”

The email came from long-time owner who prides himself on buying high end Mercedes vehicles, customizing their look and maximizing their performance. He chose RENNtech with the goal to own the fastest AMG GT63S on the planet, and the attached screen captures proved it. Mission accomplished.

The attached image contained Dragy results showing a ¼ mile time of 9.79 seconds. This was .20 tenths quicker than the run recorded last May crushing the prior ¼ mile record of 9.99 seconds. The new time is the fastest time published and recorded for the Mercedes-AMG GT63S 4-door (X290).  To top it off, looking at the Dragy we noticed a "lift" towards the end. Why? “I just didn’t want to push it too hard.”

Dragy results show a 9.79 second 133.11 mph quarter mile time - even with a lift of throttle at the end.
The 4.92 second 60 - 130 mph is equal to the fastest supercars in the world.


While the 9.79 time is a record shattering and the fastest ¼ mile on record, the 4.92 second time from 60 mph to 130 mph matches the speed of supercars.  Compare what we have to work with…so we did. Lining it up to a rolling 60 – 130 mph vs. a Ferrari SF90 (4.97 seconds), or the LaFerrari (5 seconds) and they will find how fast it really is. Very Fast.

The results would have been even better from a rolling start, but due to the owner driving the car sparingly, we will have to wait for additional results from his next outing.

So how did we get here? With over four decades dedicated to developing the fastest MB's on the planet, RENNtech leads the field in engineering and development of the highest grade in performance upgrades for Mercedes-Benz AMG and European performance vehicles. The considerable investment of time and resources dedicated to engineering and design delivers rock solid reliability beyond other tuners, at a level that owners of AMG vehicles expect from the factory.

“This car deserves to get the credit for its record setting results, but RENNtech deserves the accolades for the 100's of hours of customized tuning & engineering to get it there. This summer the car was producing over 1000 HP at the wheels even with all the heat and humidity of South Florida. I did not remove any seats, no roll cages, and don’t use E85, methane, nitrous bottles, drag slicks, or any other tricks of the trade to improve times, so I knew it could go even faster when the weather cooled off." 
Said Owner (@ed1t1ongt63s)

AMG GT 63 Edition 1 - DYNO Pull

The all-out AMG GT63 S Edition 1 (X290), that is a one-of-a-kind 1000 WHP family rocket ship with the daily comfort and reliability of a M.B. AMG. During the initial development stage in June, this beast set the record of highest power output measured on RENNtech’s dynometer (video), the first sub 10 second ¼ -mile time, and most powerful AMG GT63 S at that time.

How much faster?

“Good question. I really don’t know.. I have no intention on pushing the limits. Maybe that is question for the next owner, but my hat is off to RENNtech for building this amazing machine for me”.

Said Owner

 


The underpinnings of the AMG GT63 include RENNtech Stage II Turbo’s, ECU tuning, Carbon Fiber Air Intakes, Intercooler, Downpipes with 200 Cell Catalytic Converters, Stainless Steel Mufflers, High Pressure Fuel system, Transmission (TCU) and Drivetrain (CPC) upgrades. In addition, the custom DYNO tuning in order to optimize the car for ¼ mile runs and launches were done by RENNtech – making this rare AMG GT63S Edition 1 the fastest in the world.
