Successful Season Opener

Callaway Competition makes a run to the podium on the first racing weekend

Leingarten, 1 May 2017

Callaway Competition got off to an outstanding start at the ADAC GT Masters kick-off last weekend. Although the Swabian team did not see the checkered flag on Saturday, its performance on Sunday was respectable. The two Callaway drivers, Jules Gounon and Daniel Keilwitz, celebrated their success on Sunday after taking second place on the podium.

Third-fastest on two occasions in qualification training, one second placement, and 18 championship points – that was the successful Callaway balance after the first ADAC GT Masters weekend. The two races of the “league of super sports cars” were a genuine motorsports show and attracted more than 20,000 spectators to the Magdeburg Börde.

Premature exit: Jules Gounon in no-fault collision

The Callaway duo of Gounon/Keilwitz initially took seventh and 15th place in the two training sessions on Friday. But in qualifying on Saturday morning, the young Frenchman Jules Gounon made his mark and positioned the Callaway Corvette C7 GT3/R in third place. Thus the starting situation for the one-hour race was perfect.

Unfortunately, things turned out differently than expected. The 22-year-old was rudely ejected from the race after less than three laps: “The Audi behind me saw a gap where there wasn’t one, leading to unfortunate contact,” says Jules Gounon. The result: Tire damage and consequently a race that could not be finished.

Perfect interplay – Keilwitz/Gounon triumphant on the podium
The frustration of failing to complete the first race had evaporated by Sunday. Competing for the starting position in the second race was up to Daniel Keilwitz. Like his teammate, he burned the third-fastest lap time into the 3.696 kilometer racecourse.

Keilwitz tucked himself behind the second-place Porsche directly off the starting line. Since a chance to pass was not in sight, the team used the mandatory stop. When Jules Gounon took the wheel and came out of the box, he was past the Porsche. The duo was second at the finish line and then celebrated its success on the podium. “We are very pleased with the result,” Daniel Keilwitz exulted. “After we had such bad luck the first day, this really made us happy. It’s a great base. We are very satisfied.” His teammate Gounon agreed: “Daniel did a fantastic job today and the team worked together perfectly. It couldn’t have gone any better.”

Things did not go as well for the sister Corvette of the RWT team. The team had to give up the second race after Sven Barth was in an accident through no fault of his own. “I feel very bad for RWT,” said team leader Giovanni Ciccone, expressing his sympathy. “The incident was unnecessary and could have been avoided.”

Anticipating the second racing weekend on the Lausitzring
Team leader Giovanni Ciccone’s racing summary: “The first race went badly. It was obvious that Jules was not at fault. On Sunday we knew we would make it to the podium if we could keep third place. We were unable to pass the Porsche on the track, but Daniel was very strong on his inlap so we were able to advance to second place when we switched drivers. I am pleased about our second place finish, and do not begrudge BMW the win that they have more than earned after all those hard years. Especially with Philip Eng, who is not only a sensational driver but also a great person.”

Now Callaway is returning home to Leingarten in Swabia, ranked sixth before heading to the Lausitzring in four weeks (May 19-21) for the motorsports festival where the ADAC GT Masters meets the DTM. Callaway once again intends to have its say when it comes to earning points and podium placements.

Heartbreak at Hockenheim

Balance of Performance Adjustments Hinder Callaway Corvette’s C7 Championship Bid
by Walt Thurn –

Callaway Competition’s amazing 2016 ADAC GT Masters season came to a sudden and dramatic end. It happened twenty-two minutes and eleven seconds from the end of Race 2 at Hockenheim. It was at this moment when a damaged Lamborghini refused to let the championship-contending Corvette pass. They came in contact with each other and the Corvette crashed out of the race. This ended Corvette’s quest for the championship.

At the Nürburgring and Zandvoort races, the Corvette was almost two seconds per lap slower than the Audi and Porsche. This reduced performance was due to a total of 65 kilos (143 lbs.) of ballast being added to the Corvette after their multiple victories. Callaway Competition was hoping for a weight reduction before Hockenheim. This did not occur and the team struggled to find a way to improve their Corvette’s performance. Porsche had just won four races in a row and only carried 15 kilos (33 lbs.) of ballast and were the team’s biggest threat. Unfortunately, no competitors received any performance changes. Callaway Competition was hoping for a home field advantage, because they do extensive testing at Hockenheim.

Callaway Competition assembled a large hospitality suite above their pits prior to the race weekend to host and thank their many sponsors and supporters. The second floor transformation was the work of Commpanions (, owned by William J. Hood. Over 500 guests enjoyed excellent food, drink and watching the race. Many guests spent time inspecting a 2017 Corvette Grand Sport and a 2017 export Camaro. Both were supplied by, a Corvette, Cadillac and Chevrolet dealer located near Berlin.

The ADAC qualifying format was changed this year. In previous years, this took place on Friday before the two races. Now teams qualify on the day of each race. On Saturday, the grid times were set during a heavy rainstorm. The championship-leading Audi was on the pole with a 1:52.369. The No. 77 Corvette managed a 1:54.427 that was good for a 13th starting position. Jules Gounon had limited time driving the Corvette in the rain, but the team was confident about the young driver’s skills. They were correct. Jules demonstrated excellent driving ability and quickly threaded his way through the field at the start of Race 1. By Lap 5, he was in fifth place, right behind the championship-competing Audi. After the pit stops, the track was still wet but drying. The Corvette’s rain tires overheated and Keilwitz finished sixth. This dropped the No. 77 twelve championship points behind the leading Audi. The No. 69 Corvette of Assemheimer/Schwager was 11th, the Lipps/Barth Corvette was 13th and the Whelen Corvette finished 19th.

Race 2 was dry and sunny and Keilwitz set the sixth fastest time with a 1:40.092. It was no surprise that the lightweight Porsche captured the pole with a time of 1:39.613. 13th position was set by the Lipps/Barth Z06.R GT3 with a time of 1:40.507. In 21st position was the No. 69 Assenheimer/Schwager Corvette with a 1:41.075 and the No. 31 Whelen Corvette was 23rd with a time of 1:41.250. When the green flag fell, Keilwitz quickly moved up into fourth position and tucked behind the green No. 63 Lamborghini. The Lambo received damage to its front splitter and upset its handling. It became unstable but would not allow Keilwitz to pass. On Lap 15, Keilwitz dove into the pits early to give the Corvette to Jules in hopes of getting ahead of the errant Lamborghini. It did not work and the green monster exited the pits a half-second ahead of Jules. A slight bump was all it took to send the Corvette sailing sideways into a concrete barrier right at the driver’s door. The impact was so hard the 4,000 lb barrier broke in half. The race was red flagged and it took the rescue crews 20 minutes to extract Jules from the car and send him to the hospital. After a complete check of his vital signs, Jules was not seriously hurt. He had a deep cut on his lower left leg and a lot of bruising from the impact. It was an unfortunate way to test the crash worthiness of the new C7 GT3/R, but it saved Jules’ life.

The race resumed and the Audi (which had spun earlier) finished eighth won the championship. A third place finish for the Corvette would have given the new C7 its first championship. However, the new car’s potential is very obvious and perhaps next year we will see Corvette win the championship. When the dust settled, Corvette finished third in the Drivers Championship, second in the Team Championship, second in the Junior Championship (Jules Gounon) and first in the Trophy (amateur) Championship. The C7 GT3/R is still a brilliant new GT3 entry. It is clear that drivers Daniel Keilwitz and Jules Gounon driving the C7 GT3/R would have won the championship without the Lamborghini blocking their path. In our opinion, the best team did not win, and that is Team VETTES’ sour grapes statement!

Rollercoaster Weekend at Nürburgring
  • Callaway Competition remains Title Contender
  • Keilwitz/Gounon keep lead in Drivers’ Championship despite DNF
  • Assenheimer/Schwager duo starts 21st, finishes in the Top-10

Old Lyme, Connecticut – August 8, 2016. With last weekend’s ADAC GT Masters round at the Nürburgring, Callaway Competition has entered the all-important decisive phase in the final part of the season. The Leingarten, Germany based race team remains title contender, leading in Teams’ Championship points, despite a rollercoaster ride weekend.

The first free practice sessions confirmed that the shortened 3.2 km Nürburgring layout was not particularly suitable for the Corvettes. In addition, the ADAC’s Balance of Performance imposed a further penalty of 15 kg. Regardless, Jules Gounon and Daniel Keilwitz qualified the #77 ROLLER/Valvoline Corvette C7 GT3/R in an impressive sixth place for the Saturday race. Finishing the race in fifth place was also a great achievement, and extended the duo’s lead in the ADAC GT Masters Drivers’ Championship.

The sister Callaway Corvette, driven by Patrick Assenheimer and Dominik Schwager, displayed a fantastic charge, blasting through the field in Saturday’s race. After a disappointing qualifying, which saw the #69 Corvette C7 GT3/R down in 21st place, the two drivers fought their way back to finish in P10, securing a great Top-10 finish.

The second race on Sunday was a disappointment for Callaway Competition. After starting in 14th position, the Assenheimer/Schwager #69 entry pushed ahead to eighth place – then a move to overtake a Lamborghini ended in a collision and retirement. Plus, Gounon and Keilwitz did not take home any points on Sunday. After starting the #77 ROLLER/Valvoline Corvette GT3/R in 18th position, contact in the very first lap forced an early retirement.

“The weekend did not go as planned, but we are pleased to have kept the lead in both championship standings”, said Giovanni Ciccone, Team Principal – Callaway Competition. “There are two very interesting and challenging tracks coming up with Zandvoort and Hockenheim, but we are positive we’ll be competitive in the next race and extend our points lead. It was once again a great performance by Patrick Assenheimer and Dominik Schwager this weekend.”

Driver Quotes:
Daniel Keilwitz – #77 ROLLER/Valvoline Corvette C7 GT3/R:
“We knew that it would be a hard race given the 30kg Balance of Performance ballast. It played in our hands that the other teams were fighting each other. It went well, we have kept the lead and extended it after the first race, which was our goal. We were not able to win at Nürburgring, but we took home the points we were given.”

Jules Gounon – #77 ROLLER/Valvoline Corvette C7 GT3/R:
“I knew the track was not the issue. But our Corvette did not run as well as it did at the Red Bull Ring. It did not look too good on Friday, but the team prepared the car great for qualifying. We finished in P5 coming from sixth. We missed the podium but we kept the lead in the Championship. Therefore we are happy with the weekend.”

Patrick Assenheimer – #69 Corvette C7 GT3/R:
“We did not have an easy weekend, but the race on Saturday proved the potential of the new Corvette. We started from a weak 21st place on the grid to finish in 10th, which was a great result for the whole team. Unfortunately, we were not able to repeat this on Sunday as I am sure another Top-10 result could have been possible.”

Dominik Schwager – #69 Corvette C7 GT3/R:
“This was an up and down weekend. The tenth position on Saturday was a strong performance by Patrick and myself and the whole team. We could have improved on that on Sunday. We are all looking ahead to the remaining rounds now. Zandvoort and Hockenheim should be good tracks for us and we’ll do everything possible to help the team win the title this year.”

Callaway Competition Takes Championship Lead
in ADAC GT Masters Series


  • First Place in Drivers’ Championship
  • First Place in Teams’ Championship
  • First Place in Trophy Classification
  • First Place in Junior Classification

Old Lyme, Connecticut – July 29, 2016. After a one month break, Callaway Competition fielded three Corvette C7 GT3/R’s in last weekend’s round of the ADAC GT Masters Championship series at the Red Bull Ring in Spielberg, Austria. With a win at the Red Bull Ring (Spielberg, Austria), and following two podium finishes at last month’s Lausitzring race, the #77 Roller/Valvoline Corvette team of Jules Gounon and Daniel Keilwitz has taken over the lead in the ADAC GT Masters Drivers’ Championship. And they placed Callaway Competition in the lead for the ADAC GT Masters Teams’ Championship. On top of that, Callaway driver, Remo Lips, holds first place in the Trophy Classification and Jules Gounon is leading the Junior Classification.

At the Red Bull Ring, all three Callaway C7 GT3/R’s qualified in the Top-15 in the first qualifying session. For the Saturday race, the Gounon/Keilwitz team qualified third and finished on the podium in third place. Then, in Sunday’s qualifying session, Keilwitz put the #77 Callaway C7 GT3/R into Pole Position. He was able to remain in the lead during the Sunday race until just before his pit-stop. When Keilwitz went into a turn slightly wide, Laurens Vanthoor capitalized on the opportunity, driving his Audi R8 LMS past the Corvette. In a thrilling ending that saw two Safety-Car periods, Gounon put pressure onto front-runner Florian Stoll and his Audi, but Jules had to settle for a second place finish. The Stoll/Vanthoor team’s R8 LMS failed the post-race technical inspection, however, so the Callaway C7 GT3/R secured the race win after all.

The two Americans piloting the Whelen Corvette, Boris Said and Eric Curran, had a very strong weekend as well. At their premiere at the Red Bull Ring, the Said/Curran team qualified the #31 Callaway C7 GT3/R in 14th and 9th position. In the race on Saturday, the duo finished in the Top-10.

The #69 AutoArena Callaway C7 GT3/R experienced a weekend of ups and downs. Qualifying P10 in the first session, Patrick Assenheimer and Dominik Schwager drove to a solid fourth place and secured a top-finish for the third time in a row. Unfortunately, the #69 retired in the second race having qualified in a strong P5.”I’m very pleased to see the development of this season, that all our hard work and our efforts are paying off and that all this is being reflected in us leading the championship now”, says Giovanni Ciccone, Team Principal, Callaway Competition. “Daniel Keilwitz and Jules Gounon did a great job this weekend. But all our other drivers impressed with top performances as well and we can be proud of the whole team’s performance. But we should not rest on our laurels now, but come back at the Nürburgring strong again in two weeks.”The next ADAC GT Masters race takes place from August 5th to August 8th at the Nürburgring. Driver Quotes:Daniel Keilwitz – #77 Roller/Valvoline Corvette C7 GT3/R:
“Our goal was to take the lead in the championship and that is what we have done. It was not an easy race with the extra ballast of 30 km from the second race at Lausitzring. We tried to stay clear of everything. Other teams had to fight quite hard. During the pit-stop phase, we lost a position, but in the end it was not tragic. Our race ran as planned: I had a good start and was able to set the pace from the front. We are pleased with the result and have extended our lead in the championship.”Jules Gounon – #77 Roller/Valvoline Corvette C7 GT3/R:
“Another race track that was new to me, but I found a good rhythm early on and I really liked the atmosphere and nature here. We are very happy about having taking over the lead in the championship. Big thanks to my team-mate Daniel (Keilwitz), who drove a fantastic race. P3 on Saturday was the best we could achieve. Both Porsche and Bentley were very strong. Now it is half-time and we are leading, it feels great. But the season is still long and we have to focus race by race.”Patrick Assenheimer – #69 Corvette C7 GT3/R:
“To start from 10th and finish in fourth is a great result. The car is great. We had a good start and did not lose a position. We managed to make up some ground during the race, also thanks to a few accidents of our competitors. Dominik (Schwager) drove a really good race.”Dominik Schwager – #69 Corvette C7 GT3/R:
“P4 was the best we could achieve. We were not quicker than the ones running in front of us in the end. Every team had a little off during the race. We took advantage of that and drove through the field. A great result for Callaway Competition. The team did a great job.”Boris Said – #31 Whelen Corvette C7 GT3/R:
“We really enjoyed the weekend, the track is great and the team did a really good job. It was a good feeling to finish in the Top-10 and, overall, the whole weekend was a fantastic result for the whole team.”Eric Curran – #31 Whelen Corvette C7 GT3/R:
“All in all, it was a good weekend, it was just a shame that we did not finish in the second race. We started from P9 and we could have had an even better result than in the race on Saturday.”Sven Barth – #13 RWT Racing Z06‐R:
“Today we can show in particular, what we are capable of. The car drove well, there were no problems, so it is not a big surprise for me, because of the upward trend we have shown since the two races at Lausitz.”Remo Lips – #13 RWT Racing Z06‐R:
“A big compliment to RWT Racing. The today was really fun. The car was just fantastic and I am very happy about the initial result. It is a shame that such a thing happened (infraction) and I’m extremely sorry, especially for the team.” Click on images for high resolution downloads

Nürburg, Germany – June 5, 2016.   The Callaway Competition team traveled to the Nürburgring, planning to get some experience in VLN racing in preparation for next year’s 24 hour race. Unfortunately, a series of obstacles ultimately resulted in the team’s withdrawal from competition.

Team management decided to concentrate on competing with a single car instead of two cars. Callaway driver Eric Curran was not able to comply with licensing requirements, so the Whelen Engineering No. 31 Corvette would be piloted by GT3 champion Daniel Keilwitz, his ADAC GT teammate Patrick Assenheimer and veteran American driver Boris Said.

Foggy, rainy weather limited practice sessions and postponed qualifying several times. When the Callaway C7 GT3/R finally got out to qualify, the track was still very wet. In fact, exiting the Fuchsröhre, there was so much water on the track that the car hydroplaned, spinning into the guardrail and damaging body and suspension parts. Since handling was severely affected and suspect axle components could not be checked quickly or reliably, Callaway team management reluctantly decided to withdraw.

It was especially disappointing, considering the generous support from Whelen Engineering and the driving talent that the team brought to the racetrack. Now Callaway Competition looks forward to ADAC GT Masters racing at the Redbullring in Austria on July 24 and 25, and returning to the Nürburgring in September.

Corvette C7 GT3/R finish P1 and P2 in Race 2 of third 2016 ADAC GT Masters race weekend.
Lausitzring 2016 Race 2 - Finish


Lausitzring, Germany – June 5, 2016.   Callaway Competition finished first and second in today’s Race 2 of ADAC GT Masters’ third race of the 2016 season. The #77 Callaway Corvette C7 GT3/R with Jules Gounon and Daniel Keilwitz finished first with teammates Patrick Assenheimer and Dominik Schwager #69 Corvette C7 GT3/R coming in second, after qualifying on the Pole. The #31 Whelen Motorsport Corvette driven by Hezemans and Said had continuing power steering problems and no qualifying laps; however, the pair stormed to a great tenth place in the second race despite not having much track experience at the Lausitzring.In Saturday’s Race 1, Patrick Assenheimer and Dominik Schwager finished third in #69 Corvette C7 GT3/R while the #77 Callaway Corvette C7 GT3/R with Jules Gounon and Daniel Keilwitz finished fourth. Renauer and Ragginger’s Precote Herberth Motorsport Porsche 911 GT3 finished in P1, with runners-up GRT Grasser Racing’s Lamborghini Huracán driven by Ineichen and Engelhart.

The weekend’s results puts Callaway’s Gounon/Keilwitz team in second place with 80 points, and the Schwager Assenheimer team is in sixth place in the ADAC GT Masters standings. Callaway Competition’s Whelen Motorsport Corvette C7 GT3/R team of Hezemans and Said, with Hezemans replacing driver Eric Curran in certain races this season, is now in tenth place in the ADAC GT Masters standings.

Drivers’ Quotes, courtesy of ADAC:
Jules Gounon (Callaway Competition, Corvette C7 GT3/R), winner in general classification, P1 Junior classification:
“I have to admit, things are going really well for us. As a rookie, however, I’m not looking at the championship table but rather focusing on each race as it comes. I’m getting more accustomed to the new Corvette with each outing. My thanks to the team who, as always, have done such a great job. The race was a lot of fun. This is a highly competitive field of entrants.”

Daniel Keilwitz (Callaway Competition, Corvette C7 GT3/R), winner:
“Clearly, we’re very happy with this victory. The start went well for me. On the run-in to the first corner, I briefly got ahead of the second Callaway Corvette driven by Dominik [Schwager], but I then drifted wide of the racing line on the second corner and didn’t have enough traction. That allowed him to counter the move. So for the moment, I just slotted into place and followed behind. When the pit stop window opened, I stayed out a bit longer and went as fast as I could. That was the decisive factor in us coming out ahead after the change of drivers.”

Patrick Assenheimer (Callaway Competition, Corvette C7 GT3/R), P2 in the general classification, P2 in the Junior classification:
“What a perfect weekend! Two races and two podium finishes. Of course, we could have won the second race as well. Dominik [Schwager] handed over the car to me in the lead – but then there was an incident with a Lamborghini – apparently the Lambo had undercut the minimum 65 seconds in the pit lane and was driving very slowly in the outer pit lane. That slowed me down, and I lost the lead to our Callaway teammates. What a pity.”

Dominik Schwager (Callaway Competition, Corvette C7 GT3/R), P2:
“If you’d told me before the weekend that we’d get two podiums, I would have said, bring it on! The Lausitzring really suits our Corvette. Starting from pole position, I was initially able to defend the lead. We were unlucky during the pit stops in that the Lamborghini blocked our path. That cost us two places to start with, but I’m satisfied at the end of the day.”

Corvette C7 GT3/R victorious in second 2016 ADAC GT Masters race weekend


Leingarten, Germany – May 2, 2016.   Callaway Competition executed their plan perfectly yesterday at the Sachsenring in Saxony, Germany, culminating with a win in the Sunday race. German driver Daniel Keilwitz and Frenchman Jules Gounon (above) piloted the Callaway-built #77 Roller/Valvoline Corvette C7 GT3/R to victory on only the second weekend of the ADAC GT Masters season.

Race Summary:

Saturday 4/30, Race 1 –

  • Jules Gounon drove the #77 Roller/Valvoline Corvette C7 GT3/R to second place; however, the race was interrupted repeatedly. Then, several positions were lost during a safety car deployment while the #77 Corvette made its mandatory pit stop/driver change. After pitting, Daniel Keilwitz was able to regain several positions, ultimately finishing fourth.
  • The #69 AutoArena Corvette C7 GT3/R qualified and started 17th, but earned a drive-through penalty following a collision, resulting in a 19th place finish.

Sunday 5/1, Race 2 –

  • Piloting the #77 Roller/Valvoline Corvette C7 GT3/R, Daniel Keilwitz blasted from P9 to third place right at the start. In the second lap, he maneuvered past Laurens Vanthoor’s Audi R8 into second place. Four laps later, Keilwitz got around pole-sitter Luca Ludwig’s Mercedes AMG to take the lead. Then Daniel increased the margin to more than seven seconds before the mandatory pit stop and driver change.
  • When Jules Gounon took over, he maintained the lead. The #77 Corvette was 1.5 seconds per lap faster than the competition. Then the safety car was deployed for a Bentley Continental GT that spun off the track. After the restart, Jules extended his lead again and, at the end of the race, crossed the finish line four and a half seconds ahead of second place. The Frenchman also won the Junior Class in only his fourth race in the ADAC GT Masters series.
  • Dominik Schwager and Patrick Assenheimer drove the #69 AutoArena Corvette C7 GT3/R from a P18 start to a solid 13th place finish after several hard-fought battles and a subsequent drive-through penalty.


Giovanni Ciccone – Callaway Team Manager and Callaway Competition Co-Owner:
“We are really proud of our drivers. Sunday was absolutely perfect! Daniel had an incredibly good start and then Jules controlled the last stint without any trouble. It is simply awesome to score this first victory with the new Corvette. All the hard work over the winter has now paid off.”

Daniel Keilwitz – #77 Roller/Valvoline Corvette C7 GT3/R:
“I was on the gas at the right time (at the beginning of the race) and that was crucial. Of course, I was also lucky that there were enough openings and I decided for the outer rail. The plan came together just as I had envisioned it. With new tires, we could get a good head start in the first laps. Jules did a great job at the finish. It’s a deserved payoff for the whole Team for the hard work throughout the entire winter and a great birthday gift for Giovanni (Ciccone).”

Jules Gounon – #77 Roller/Valvoline Corvette C7 GT3/R:
“It was really great! I don’t know how to describe it, but Daniel’s start was incredible. He also gave me the perfect car with very good tires and that made my job easier, of course. Then I could really gas and drive away in the lead, and then I saw the Safety-Car and had to do the whole work again. My strategy in the first three laps was to push carefully and then to take control of the race and this was exactly according to plan. I am very pleased to drive with Daniel this year, as I still have a lot to learn from him.”

Patrick Assenheimer – #69 AutoArena Corvette C7 GT3/R:
“Unfortunately, we pitted almost one second too soon and got penalized. But I think if you look at the laps over the weekend, then we’ve demonstrated decent performance. We held a Top-10 pace and without the penalties we could have continued to do better. I had today (Sunday), as well as yesterday, seven or eight passes and a lot of fun. We must simply see to it that, through Qualifying, we get a better starting position, so we can get further ahead right from the start of the race.”

Dominik Schwager – #69 AutoArena Corvette C7 GT3/R:
“It was a difficult weekend for us. Unfortunately, both Patrick and I didn’t perform quite right in Qualifying. We had two good races but, unfortunately, we didn’t do enough. On Saturday, we were a little unlucky and, from our point of view, we were pretty severely punished. The penalty on Sunday was very exasperating and a pity. But I am very pleased that the other car (#77) could get the victory, because they really did a great job.”

  • Corvette C7 GT3/R shows potential in first milestone
  • Turbulent weekend for Callaway Competition

Leingarten, Germany (April 18, 2016) – Callaway Competition experienced a turbulent weekend at the ADAC GT Masters season opener at Oschersleben last weekend. With one car crashing in the first turn, an unexpected pit stop problem with the second car, and an unexplained power glitch in the third car, Oschersleben proved to be quite challenging. However, the Callaway team was still able to demonstrate the tremendous potential of the new Corvette C7 GT3/R and it is looking forward to the upcoming races.

Callaway Competition brought three Corvette C7 GT3/R’s to Oschersleben. After a shortened development period and limited test sessions prior to the season opener, it was the first time the new cars’ performance was actually measured against the competition.

Patrick Assenheimer, who finished in 9th and 11th Place with his new teammate, Dominik Schwager, was probably the driver who found his way around Oschersleben best with the new AutoArenA C7 GT3/R. It would have been possible for them to advance to fourth place in Sunday´s race, but a problem during the pit stop spoiled their chances for a better finish.

Teammate Daniel Keilwitz did not have luck on his side either. Starting from a great P2 on the grid in the #77 Roller/Valvoline C7 GT3/R for Sunday´s race, he had a terrific start. However, he was taken out in a collision in the very first corner.

Piloting the #31 Whelen Engineering C7 GT3/R, Boris Said and Loris Hezemans were suffering with performance issues since the free practice sessions on Friday. A problem, which could not be located or fixed throughout the weekend resulted in 10km/h less top-speed on the straights.

“In general, we are fairly happy with the weekend, but I would have liked to drive home with three cars”, say Giovanni Ciccone and Ernst Wöhr, Callaway Competition Team Principals. “It was unfortunate that we had to retire right at the start of the second race, but accidents like this one do happen. We know of the potential of the Corvette. All we need are more test kilometers to improve performance and resolve the last details.”

The next ADAC GT Masters race will take place at the Sachsenring in two weeks.

Driver Quotes –

Daniel Keilwitz:
“The accident at the start was totally unnecessary and very frustrating for us. The driver took out three cars at once. This should not happen. We could have achieved a really good result. But, all in all, we are happy with our weekend. The potential of the Corvette C7 GT3/R is great and we are looking forward to the races at Sachsenring.”

Patrick Assenheimer:
“Ninth position is not ideal. But big compliments to my teammate Dominik (Schwager), who handed me the car in P6. We are on the right way with our speed and the next races will be better.”

Dominik Schwager:
“I think the weekend was positive. I would have been happy with a position between 10th and 15th looking at the strong starting grid. We must do more tests; the car is new. We should look better at race tracks that offer faster passages. We are on the right way and I am excited about the next races.”

Boris Said:
“The handling felt good in the second race and we made great progress. However, we never could solve the power loss issue at the racetrack. Anyway, I’m sure we’ll be in attack mode for the next race.”

April 6, 2016 – “Look! Corvette GT3 2nd Quickest at Oschersleben, Germany”

Oschersleben Shakedown

Whelen Callaway Corvette C7 GT3/R

The 2016 ADAC GT Masters Championship season begins on April 15-17 at Motorsport Arena Oschersleben in Oschersleben, Germany. The tight, twisty 2.29-mile facility is a great place for fans to watch the action. Large berms and grandstands allow spectators to view the event from high vantage points. The German sports car series is preparing to celebrate their 10th anniversary when the green flag falls for race one on Saturday. The event is packed with 34 GT3 cars from eight manufacturers in two classes: GT and Gentleman. Sixty-four drivers will compete to win the 2016 ADAC championship.

Callaway Competition, headquartered in Leingarten, Germany, is the only constructor of Corvette GT3 race cars, but they do not race in the U.S. per an agreement with GM. They brought three 2016 Callaway Corvette C7 GT3/R’s to the preseason ADAC test session at Oschersleben and one C6-based Z06.R GT3 Corvette.

The No. 77 Callaway Corvette C7 GT3/R driven by 21-year-old Jules Gounon set the second quickest time on the first day of testing at 1:27.758, only 0.46 seconds behind the leading Audi R8. Jules will be co-driving his Corvette with 2013 ADAC Driver Champion Daniel Keilwitz. Keilwitz was fourth quickest on the second day of testing.

U.S. drivers Boris Said and Eric Curran tested their No. 31 Whelen Engineering C7 GT3/R. Due to Eric’s busy schedule (he co-drives the No. 31 Whelen Motorsports Daytona Prototype in the IMSA WeatherTech United Sports Car Championship series), Loris Hezeman will be Boris’s co-driver. The young, 18-year-old Loris comes from a family with extensive racing heritage. His older brother Mike won the 24 Hours of Spa driving an ex-Pratt & Miller C6R Corvette.

The third Callaway entry is the No. 69 C7 driven by Patrick Assenheimer and Dominik Schwager. RWT Racing’s ITK Engineering-sponsored C6 Z06.R GT3 driven by Sven Barth and Remo Lips will compete in the Gentleman Championship category.
The season opener will be held at the same circuit as this preseason test. Fourteen additional races will take place at tracks in Germany, Austria and the Netherlands. All of the races will be broadcast live on the TV SPORT1 channel in Europe. The ADAC GT Masters adheres to the FIA GT3 rules format that requires driver changes during each 1-hour event. Pit stops must be no quicker than 70 seconds, with quicker stops incurring a 30-second stop-and-go penalty. The starting field is extensive and varied. Twenty teams, including eight newcomers, have registered 34 cars from eight different manufacturers for the opening race. This includes six new or upgraded models: Audi R8, BMW M6, Corvette C7, Lamborghini Huracán, Mercedes-AMG and Porsche 911—which will be up against last year’s debutants, Bentley Continental and Nissan GT-R. There are not only eight new teams on the ADAC GT Masters grid in 2016 but also a lot of drivers who are new to the series.

“The 2016 ADAC GT Masters goes into its anniversary season with a distinguished field of competitors,” says ADAC Sports President Hermann Tomczyk. “The ADAC GT Masters has long been regarded as one of the top GT series in Europe. When we first came up with the concept in 2007, we certainly didn’t expect this level of success. In recent years, the ADAC GT Masters has also established a reputation as a springboard for youngsters embarking on a career in professional motorsport.” Callaway Competition has been an ADAC GT Masters regular since the inception of the series. As in previous years, RWT Racing will be pinning their hopes on the predecessor model: the Corvette Z06.R GT3. The team is highly competitive and well managed. Daniel Keilwitz holds the record for the most ADAC GT Masters race wins and claimed the driver title in 2013. He is beginning his sixth season with the Callaway Competition GT3 Corvette team. Let’s hope another Callaway Competition championship is in the near future. Stay tuned.

Callaway Corvette C7 GT3/R Team Partners with Whelen Engineering

– Eric Curran and Boris Said to Pilot Callaway Competition Racer

Old Lyme, Connecticut – Callaway is proud to announce that Whelen Engineering Inc. will be the primary sponsor for the brand new Callaway Corvette C7 GT3/R. Beginning in 2016, the Callaway Competition-built racer will compete with the world’s fastest GT cars in a variety of racing series worldwide.

Founded in 1952, Whelen Engineering designs and manufactures premium quality audio and visual warning equipment for the Automotive, Aviation, and Mass Notification industries. With facilities in Connecticut and New Hampshire, Whelen products are designed, manufactured, and assembled in the USA.


Sonny Whelen elaborates on the Callaway-Whelen association: “I’m very excited about working with the Callaway team in Europe next year. They have produced an amazing Corvette that will be a perfect way to promote the Whelen brand. Our objective is to penetrate deeper into European markets with our all-American made emergency lighting and siren products. We believe that Callaway’s presence in motorsports along with their commitment to quality and success will be an excellent fit and help us to expand our sales efforts in the European marketplace.”

Distinguished racers Eric Curran and Boris Said are set to pilot the first Callaway Corvette C7 GT3/R. Boris has driven for the Callaway team since the 1990’s, and Eric is a prominent racer with an impressive winning record. Among their other achievements, Boris has captured pole position at Le Mans in a Callaway Corvette and Eric recently celebrated major victories at Detroit and Road America in the IMSA Tudor Prototype Series in a Whelen Corvette.


Curran looks forward to 2016: “It’s really exciting to be entering into yet another program with Whelen Engineering. Sonny Whelen has been a close friend, sponsor, and teammate of mine for nine years, so to be venturing into a new program combined with Callaway Cars is a really big deal. All the guys at Callaway have been good friends for over 15 years and I’ve done a lot of work with the Callaway Car Company. Boris and I have been teammates for many years in the Whelen Engineering GT Corvette. It’s exciting to be teammates with Boris again and to combine all these things made in America.”

Boris adds, “I’m excited to be back in a Corvette with Whelen and Eric. We had many great years together in the past and to do it all over again with my good friends at Callaway is the perfect fit. I’ve always said that Corvette teams should all have American drivers and an American sponsor. This is how it should be. This Whelen Callaway GT3 Corvette is the coolest looking race car I’ve ever seen and we get to drive it!”

The Callaway Corvette C7 GT3/R was unveiled on October 3 at a packed presentation during the ADAC GT Masters Season Finale at the legendary Hockenheimring in Germany. The new car replaces Callaway’s Z06.R GT3, one of the most successful cars in the history of ADAC GT Masters with 23 victories.

Reeves Callaway stated, “We look forward to fielding this worthy effort: A quintessential American Brand. With American Drivers. Fueled by an American Company’s sponsorship. In a premier European series and settings… we could not be more proud.”

Callaway Corvette C7 GT3/R World Debut at Hockenheim

Hockenheim, Germany – This weekend’s ADAC GT Masters Season Finale was the backdrop for the unveiling of Callaway Competition’s new Callaway Corvette C7 GT3/R. Following a brief presentation to media and invited guests, the successor of the C6-based Callaway Z06.R GT3 was displayed to the public for the first time on October 3, 2015 at the Hockenheimring in Germany.

Constructors of GT race cars since 1990 and based in Leingarten Germany, Callaway Competition possesses a wealth of experience, technical know-how and a broad network of specialized professional partners. These elements were crucial to conduct such a large undertaking.

After nearly two years of comprehensive planning, intensive development and expert fabrication of vehicle components, Callaway Competition completed the first C7 GT3/R just a few weeks ago. Its striking design comes as a result of the collaboration between Canadian designer Paul Deutschman and team owners Giovanni Ciccone and Ernst Wöhr. Mike Gramke, Uwe Hoffmann, Florian Möhring and Andre Zanke were also heavily involved in the vehicle’s development. Rüdiger Geckler coordinated the delivery of all components and the detailed assembly work was taken on by Herbert Schürg. All of these people played a key role and are acknowledged for their hard work and dedication.

The result is a GT3 racer built to meet all FIA rules and regulations. Powering the Callaway Corvette C7 GT3/R is a Chevrolet-based 6.2L V8 engine producing 600 horsepower, mated to an X-Trac 6-speed sequential gearbox with paddle-shift technology. Having put the C7 GT3/R through its paces, the development team is proud to report that it surpasses its predicted performance.

The new Callaway Corvette C7 GT3/R’s will take to the track starting in 2016, competing with the world’s fastest GT cars in a variety of racing series worldwide. The first C7 GT3/R to be campaigned by Callaway Competition’s in-house race team is sponsored by Whelen Engineering of Chester, Connecticut, manufacturers of premium quality warning and signaling devices.

Ernst Wöhr and Giovanni Ciccone, managing partners of Callaway Competition, stated: “We wanted to set another milestone in our company’s history with our new design, developing and constructing a future-proof vehicle that will be produced from 2016 and used for many years to come. As a small, privately owned team lacking the finances and human resources of the big automotive groups, we knew from the outset that approaching a project of this magnitude would be very daring. Therefore, first and foremost, we have to thank our employees and partners who have made it possible to finally set the C7 GT3R on its wheels. Everyone has given more than 100% and we truly can’t thank them enough. We can be proud of our performance to date and are confident we will be rewarded with good results in the many races ahead.”
