Reiter Engineering GmbH & Co Kg is a German racing team founded in 1994. The company is named after engineer and founder Hans Reiter. In 2000, Reiter entered a Lamborghini in the FIA GT Championship with its own Diablo GT built by the team. In 2003 the Diablo GT was replaced by the newer Lamborghini Murciélago R-GT, with increased development from Audi Sport, before also becoming the constructor of the Gallardo and Camaro GT3s for the FIA GT3 European Championship and later the ADAC GT Masters. Besides running the factory squads in their respective championships Reiter also builds and sells its cars to other teams for various uses.
Currently Reiter Engineering produces the KTM X-Bow GT4, the Reiter Gallardo R-EX and the SaReNi Camaro GT3.
In 2016 Hans Reiter launched his latest concept ''Reiter Young Stars'' a championship designed to help propelle the futures of young drivers and engineers hoping to climb the motorsports ladder.
In 2000, Reiter debuted its custom-built Diablo GT in the international FIA GT Championship, with backing from Lamborghini. The car was a variant of the Diablo GTRs used in the Lamborghini Supertrophy one-make series, adapted to better compete in FIA GT. Following a short 2000 season, Reiter managed to score their first points in 2001 with a fifth-place finish in the season finale.
A points-scoring finish would not come again for the Diablo GT until it was replaced by the newer Murciélago R-GT at the end of 2003. This new car would earn points on its debut in 2004, with a third place at Valencia. The following year, Reiter managed another point at its home round in Oschersleben.
