NLS — the Nürburgring Langstrecken-Serie, formerly known as the VLN — is a long-running endurance championship raced entirely at the Nürburgring in Germany, now run under the ADAC RAVENOL banner.
What sets it apart is the track. Every race uses the combined layout of the modern Grand Prix circuit joined to the legendary Nordschleife ("North Loop"), making a lap of more than 24 kilometres — one of the longest circuits in the world.
NLS is famous as amateur-friendly, club-style endurance racing. A single enormous grid — often 100-plus cars — mixes professionals and amateurs across many classes at once, from GT3 machinery at the front through GT4, prototypes and production-based cars down to near-standard touring cars. Because every class runs together, faster and slower traffic constantly share the road.
It also serves as the traditional proving ground for the Nürburgring 24 Hours, though it is a separate championship from that standalone event. For how a round actually unfolds, see how an NLS race weekend works.
