A Test of Power and Performance Quarter Mile – The Drag Strip

On a hot and humid night in May, RENNtech arrived at Palm Beach International Raceway’s drag strip with a brand-new Mercedes-AMG GT 63 S 4-door Coupe. The menacing family “sedan” had left the factory in Affalterbach, Germany, with the AMG developed 4.0L (M177) twin-scroll BiTurbo V8 engine 630 HP and 664 lb-ft of torque, but since arriving in the United States, the car had benefitted from RENNtech’s engineering and know-how for developing some seriously fast Mercedes-Benzes in Stuart, FL.

for SRO America Season Opener

NEW BRAUNFELS, Tex., STUART, FL (February 25, 2019) – After winning the Pirelli World Challenge SprintX Pro/Am title in 2018, 18 year-old champion Parker Chase is returning to the series this week for the season opening event at Circuit of The Americas with RENNtech Motorsports. The season will kick off with a double header race event at the Austin circuit, where Chase, a Texas native, will share the driving duties of the No. 89 Mercedes-AMG GT4 with Reinhold Renger in Pirelli GT4 America‘s East Pro/Am class.

“I’m thrilled to be returning to SRO America this weekend,” said Chase. “I got the call late Friday and the deal came together very quickly. I last raced in the GT4 class in 2017, and it’s been great to watch the competition in that series grow.  RENNtech Motorsports has put a lot of effort into this first event, and I’m looking forward to working alongside with Reinhold to bring them some strong results.”

Chase’s invitation to drive for the team came less than a week before the first practice session, but the young champion aims to quickly get up to speed with the new team and new machinery.

“We were looking for a strong silver to put in the Mercedes-AMG for this first event, and Parker Chase came highly recommended,” said team owner Hartmut Feyhl. “Given his excellent record in the series and being a local to the circuit, he seemed like the natural choice for our first event of the year. We’re proud to have him on board and are excited to get this event started.”

While the 2019 SRO America season is just getting started, Chase kicked off his 2019 race season with the Rolex 24 at Daytona, where he performed well during the IMSA WeatherTech SportsCar Championship season opener, before torrential downpour and hazardous track conditions ended the race early. He gained additional track time last week with a one-day test at Sebring International Raceway in preparation for the next rounds of racing on his 2019 calendar. Chase has yet to announce his race schedule for the full 2019 season, but has held discussions in both IMSA and SRO America, with hopes to make an announcement soon.

With the return to the Circuit of The Americas, RENNtech Motorsports starts their first full Season at the same track where they celebrated their inaugural race in November 2018. Having had a successful first outing at the 24H Series, RENNtech brings a huge Momentum to the first race of the season. Proving to be a serious contender right from the get-go, RENNtech Motorsports was able to set the Pole Position time and finished the race after 24 hours just 50 seconds behind the leader in class.

Teaming up with Parker Chase is veteran driver Reinhold Renger from Rothenburg, Germany. Reinhold is a long-time factory Mercedes-AMG driver and current Chief-Instructor of the AMG Driving Academy. He scored his biggest success at the 2008 24h-Nürburgring, scoring the win in his class. He is the current Blancpain GT Series Asia champion, which he won with the Mercedes-AMG GT4 as part of the Gruppe-M Team. At RENNtech Motorsports the speed and experience of Parker and Reinhold built a dynamic duo, ready to fight for the highest positions.

Official practice sessions for rounds one and two of the Pirelli GT4 America championship at Circuit of The Americas begin Friday March 1^st. The GT4 America series will host an impressive field of 33 competitors on the 3.4 mile, 20 turn, permanent road course, the arguably most prestigious race-track in North America. Race one will begin Saturday, March 2^nd at 1:05PM Central, followed by race two on Sunday, March 3^rd at 10:10AM; both races will air live on www.world-challenge.com.

Sufficient is not enough

The Rolls Royce cars are the epitome of luxury and comfort. For years Rolls Royce did not bother with performance figures, and if you insisted, the answer was sufficient. In 1988 that was 200 hp from a 6.75 L V8 in a 5000 lb car, which is sufficient if you do not accelerate beyond the 25 MPH speed limit on Worth Avenue. In 1985 Grey Poupon advertising campaign featured a man chauffeured in a Rolls Royce searching for more mustard. The ad hit the nail on the head; the best way to enjoy a Rolls Royce was by hiring a chauffeur and enjoying a sandwich in the back seat, because driving the car was not much fun.

RENNtech E63 S – Civil Unrest

Economies of scale give car manufacturers a big incentive to use the same engine across several model lines. However, things are not quite that simple, and while it is true that when you make more of something the unit cost drops, it does not always make sense to use exactly the same components for every application.

RENNtech sets record for fastest Mercedes on the Nordschleife

Flugplatz (“air field”), Schwedenkreuz (“Swedish cross”), Fuchsröhre (“foxhole”), Karussell (“carousel”) – the sections of the legendary Nurburgring-Nordschleife are well known to motorsports fans and track day enthusiasts around the world. No other race-track is more demanding, nowhere else can car and driver reach their limits as on this 20,832 km road-course. Therefore, record breaking attempts are virtually an everyday occurrence. The AMG specialists from RENNtech, conveniently located at the Nürburgring, were now able to set the record for the fastest street-legal Mercedes with their AMG GT R.

Mercedes CLK GTR | A True Supercar Unicorn

What defines a true Supercar nowadays? Exotic Looks, Power, Exclusivity. When Mercedes-AMG set out to succeed in the FIA GT1 class in 1997, they were required to build a road version of their race-car. This led to the creation of one of the most iconic Supercars, often referred to as the ‘Unicorn’.

So, what makes the CLK GTR a true supercar?

Exotic Looks? Mercedes-AMG’s Motorsport specialist HWA (named after AMG Co-Founder Hans Werner Aufrecht), who built the race-car made only slight changes to the road version. A few of the adjustments included; a fixed rear wing, increased ground clearance and an interior equipped with airbags, electronics and an A/C system.

Power? The standard CLK GTR coupe is equipped with a 6.0L V12 Mercedes engine, producing 623 HP and 539 LB-FT. As if this wasn’t enough, HWA released a SuperSport edition where they upgraded to a 7.3L V12 Mercedes-AMG engine. The CLK GTR SS raises the power output to 655 HP and 580 LB-FT. A sprint to 60mph only takes 3.4 sec and runs a ¼ mile in 9.6 sec with a trap-speed of 145mph, all from a standing start. An impressive 320km/h / 199mph is possible in the CLK GTR.

Exclusivity? After Mercedes-AMG initially built two Prototypes (which were later turned into road legal versions) and 7 race cars, they only manufactured 27 road legal vehicles. Six of those were roadster variants, which were built without a roof and two right-hand drive vehicles, both exclusively built for the Sultan of Brunei (one coupe and one roadster). The special SuperSport edition, equipped with the 7.3L Mercedes-AMG engine, was only produced three times. Therefore, you can clearly define the CLK GTR as a true Unicorn.

At the time of the release, the price of the Mercedes-AMG CLK GTR was over $1.5 million, making it the most expensive production car of its time. The Mercedes-AMG CLK GTR is one of the most unique and timeless Supercars to date. RENNtech has been putting one of the three CLK GTR SS through their test, including road course laps at Palm Beach International Raceway. Full performance analysis and video will be released soon. In between testing, the CLK GTR SS is presented at the RENNtech HQ showroom.

If you are lucky enough to ever see one in person, make sure to value the moment. A unicorn does not appear too often.
