Bilster Berg
The Bilster Berg Drive Resort is a private motorsports club for automotive enthusiasts and manufacturers with a  long motor racing circuit in , a district of the village of Bad Driburg in the Teutoburg Forest. The track is built on land formerly used by the British Army as an ammunition depot; it was designed by Hermann Tilke, with input from Walter Röhrl. History
The site was used since the 1970s as an ammunition depot for the British Army of the Rhine. When Great Britain withdrew its forces in 1993 following German reunification, the  site reverted to its previous owner, Count Marcus -Sierstorpff. The Count, a motorsports enthusiast, thought the site would be suitable for a motorsports track; his earlier attempt to build a track there was stymied by the 2008 financial crisis. It was the first track built in West Germany in 80 years, and was designed by Hermann Tilke, who waxed enthusiastically about building a track with a constant gradient. Design
Because of its seclusion and relative anonymity, it was envisioned that it could be used for sensitive driving exercises, including manufacturer testing and advanced driving instruction for bodyguards or special forces. The track features  of elevation change over its  length, with maximum gradients of +21/-26% through 44 crests and dips and 19 turns. In 2019, the driving simulator software RaceRoom added Bilster Berg to its tracks. Lap times
