Callaway Competition Wins Both Saturday and Sunday Races at the Red Bull Ring!
Both Callaway drivers start on the Pole and win both races; Callaway now leads both Teams’ and Drivers’ Championship Points Standings.
This weekend, in the picturesque town of Spielberg, Austria, Callaway Competition completely dominated the ADAC GT Masters’ Red Bull Ring event. Corvette drivers, Marvin Kirchhöfer and Daniel Keilwitz, enjoyed a spectacular outing, each capturing Pole Position for the Saturday and Sunday races and then winning both races. Saturday’s Race 1 was Kirchhöfer’s first ADAC GT Masters victory while, on Sunday, Keilwitz got his 8th career Red Bull Ring win in a mostly-rainy Race 2, finishing 4.2 seconds ahead of a charging, second-place Lamborghini Huracán GT3.
Following this weekend’s performance, Kirchhöfer and Keilwitz have a 25 point advantage over second place in Drivers’ Championship standings, and Callaway Competition is 12 points ahead of second place in the Teams’ Championship race.
The next race weekend on the ADAC GT Masters circuit is scheduled for August 3-5, at the Nürburgring in Nürburg, Germany. The time-honored racetrack is considered to be Callaway Competition’s “home-track”, but they’ll have to bring their A-game as, once more, they’ll be competing with the world’s fastest GT3 race cars: Audi, BMW, Ferrari, Honda NSX, Lamborghini, Mercedes-AMG and Porsche.

Marvin Kirchhöfer: “We weren’t expecting to win twice. I’m all the more delighted now that we’ve achieved that. It was a perfect weekend for us, with a maximum points yield. Next on the itinerary are some tracks where it’s going to be harder for us to compete at the front.”

Callaway Double Victory
Race #1: Saturday, June 9
Race #2: Sunday, June 10
A note from Reeves following the Double Victory . . .
The goal of every race team is to have a weekend like this. Overall, this is the eighth win for the team at Red Bull Ring. The track clearly suits the strengths of the car. And as you can see, wet or dry.
This victory is a testament to not only our remarkable drivers, but especially to the men in the team from a mechanical, engineering and strategy points of view. I would like to take just a moment to relate several details at this point in the season.
The Callaway team is responsible for the design and construction and campaigning of the Corvette GT3 race cars, worldwide. This is unique among the teams competing. The other cars, Porsche, Ferrari, Mercedes, BMW, Lamborghini, Audi, Honda, are constructed by the OE factories. Our authorization from GM is to be responsible for the design, build, sales, and Homologation with the FIA. As such, you are witnessing the final proof of the efforts of a small group of very talented men who truly stand out among other first-class constructors and first-class race teams. The Callaway team does all of those functions.
It is important to remember that funding is the fuel of motorsport. Callaway Competition GmbH secures its own sponsorship from companies in Europe, and operates on less of a budget than the other factories. General Motors does not fund the program. Our revenues are generated by sales of race cars. The GT3 class is raced in every country of the world, so the potential market is large.
A comment about the competition: There are 37 cars on the grid. In qualifying, the field is separated by only 1.4 seconds. I know of no closer form of automotive competition. Each manufacturer has the possibility of a win at each race. This is what keeps everyone coming back. This is what keeps the highest level of driver talent seeking a place in ADAC GT Masters competition. Callaway values competing against the most difficult competition.
Ironically, Callaway was not able, on short notice, and even being the 2017 Champions, to raise sufficient funds to compete in the USA in 2018. For 2019, we hope to rectify that situation by selling cars into US competition, and supporting them with engineering and parts support similar to Audi, Mercedes, and Porsche.
We now have a 25 point lead in the season championship. The ADAC GT Masters series resumes at Nürburgring in August.

Callaway Competition: An International Effort
- Commercially available race cars for FIA GT3 competition worldwide.
- Designed, constructed and homologated by Callaway Competition GmbH, under exclusive authorization by Chevrolet Division, GM.
- Configurable for all GT3 racing series.
- Incorporates experience gained by Callaway Competition GmbH during 20+ years of international sports car racing.
Motorsports has always played a crucial role at Callaway. The marque possesses a legendary record at many of the world’s great race tracks: Spa, Suzuka, Paul Ricard, Nurburgring Nordschleife and GP courses, Monza, Vallelunga, Hockeheim, Daytona, Lime Rock, Road Atlanta, Sears Point, Laguna Seca, Charlotte, Texas World Speedway, Watkins Glen and Mugello.
Currently, Callaway Competition – Germany campaigns its own GT3 race team and sells Corvette GT3 race cars and support parts and equipment to leading race teams throughout Europe. Since GM has expanded Callaway’s exclusive authorization to homologate, construct and sell Corvette GT3 race cars worldwide, including North America, a new organization, Callaway Competition – USA, also constructs and sells the Corvette race cars.
The first Callaway Corvette C7 GT3-R’s were constructed by Callaway Competition in Leingarten Germany, setting new standards in the league of GT3 race cars. Development of the Callaway Corvette C7 GT3-R began in mid-2014 on CAD, under the supervision of Ernst Wöhr and Giovanni Ciccone, with technically-relevant parts designed by Mike Gramke and Uwe Hoffmann.
The body and dashboard were CAD-designed by Paul Deutschman, Callaway’s designer of over 30 years, of Deutschman Design – Montreal, Canada. By the end of 2014, vehicle design was established and, in the spring of 2015, prototype construction commenced at Callaway’s German facility.
Callaway Competition supplied dimensional data for specialist suppliers who milled forms for body parts. The carbon fiber parts from these forms were chiefly manufactured in Leingarten, with some produced by friendly firms.
The only stock components retained from the Corvette C7 are the chassis, which is reinforced with the roll cage, the lower control arms, the upper half of the rear bumper and the tail lights. The naturally aspirated 6.2-liter engine was carried over from the Callaway Corvette Z06.R GT3 with minor changes. Other parts were newly developed and manufactured, with the major part of the technical components from aluminum and carbon fiber hand-built in Leingarten.
The front spoiler, diffuser and rear wing aerodynamic components were developed and implemented in CAD (Paul Schreiber and Alex Koppe). The shape and the profile of the rear wing corresponds to all the latest developments in aerodynamics.
Callaway Competition General Manager Ernst Wöhr and Team Manager Giovanni Ciccone utilized all their race car building experience in the construction of the Corvette C7 GT3-R.
