Corvette C7 GT3-R PkT Sprint

The all-new Callaway Corvette C7 GT3-R follows on from the famous Corvette Z06.R GT3 with even more power and improved aerodynamics. This amazing race car was developed by Callaway Competition, based in Leingarten (Heilbronn, Germany). It has a V8 engine with 6.2 litres under the bonnet that produces up to 600 hp, making it the fastest race-optimised C7 version to date.

The company Callaway Competition based in Leingarten (Heilbronn, Germany), 151 kilometers south of Frankfurt and 10 kilometers west of Heilbronn. Callaway Competition was established-one in 1985 under the name “Woehr & Ciccone” company that has specialized since its foundation on body manufacturing, vehicle repairs and racing modifications. In 1988, the company “Woehr & Ciccone” expanded to take over the distribution of Callaway in Europe. The racing department Callaway Competition got its name in 1994.

The Callaway Project C15, was originally known as Corvette Z06.R GT3, a competition version of the Corvette C6 Z06 built to compete in FIA GT3 category GT racing. The cars are built at Callaway Competition's facility in Leingarten, Germany and raced in the FIA GT3 European Championship. With Chevrolet's 2014 Corvette model change, Callaway Competition began development of the C7 GT3-R racecar. The new car made its debut at the Hockenheimring, in Germany, in October 2015. Chevrolet Division of General Motors granted exclusive authorization to construct, homologate and sell Corvette C7 GT3-R's worldwide, except North America where Cadillac Racing campaigned in GT3. For the 2018 racing season, Chevrolet expanded their exclusive authorization to include North America, as the Cadillac Racing program was terminated.

The first three Z06.Rs were built for Callaway Competition themselves, followed by the rest for privateers. As of 2007, ten have been built to compete in FIA GT3 as well as the ADAC GT Masters and Belcar series.

In 2007, the Callaway Competition team, competing under the Martini-Callaway title in the FIA GT3 European Championship earned three race victories and three second-place finishes and won the Teams Championship. Drivers Luca Pirri and Jürgen von Gartzen took the runners-up in the GT3 Driver’s Championship.

In 2010, Callaway drivers Christian Hohenadel and Daniel Keilwitz finished the season as FIA GT3 champions, taking four victories to secure the title with a round to spare. The knowledge and experience learned from the race program is used in the Callaway C16 series of road-going sports cars.

Except for 2011, Callaway Competition has been competing in the ADAC GT Masters series. Callaway Corvette C6 and C7 racecars have also been active in other series. For the 2017 race season, Callaway and its drivers captured the ADAC GT Masters Teams Championship, Drivers Championship, Junior Championship and second place in the Trophy Championship.
