The Nürburgring is a race track named after the Nürburg castle in the Eifel region. Today, the Nürburgring is best known for the Nordschleife , the longest permanent race track in the world.
The 24-hour race for touring cars is held annually on the Nordschleife. The NLS (formerly VLN) and RCN racing series are held exclusively at the Nürburgring.
In addition, many vehicle manufacturers test their vehicles on the Nürburgring.
