Official timing by the Nürburgring Along with races and timing events under the rules of their respective
sanctioning bodies, the operators of the track have instituted official rules as of 2019 that govern the measurement and certification of lap time on the Nordschleife, with measurement over the full length of the track timed with a flying start. Timekeeping is supervised by a notary and the vehicles are scrutineered with regard to their series-production state.
Timing by media The German magazine
sport auto publishes its "Supertest" of cars, in which the lap time (usually driven by editor-in-chief
Horst von Saurma) at the Nordschleife is the most discussed result. The magazine also runs a challenge for the fastest lap time driven with a car that is road legal (
TÜV) and registered in Germany. The road legality rule also applies for the tyres. British motorcycle magazine
Performance Bikes began testing their bikes in a regular feature at the Nordschleife in March 2007 and finished in December 2007. Bikes were tested by Dale Lomas and Brendan Keirle (then known only as "The Baron"). As with
sport auto, all machines tested are road-legal (
MOT) and shod with road-legal
Bridgestone BT002 Pro Race tyres. To date there are 28 lap times published in the regular feature. As motorcycles are forbidden to participate in industry pool sessions and after-hours test sessions,
Performance Bikes were forced to test during quiet mid-week tourist sessions, where speed limits apply in some sections. This means their lap times are measured from bridge to gantry (see below) and are approximately 22 seconds shorter than a full Nordschleife lap. Nordschleife runs are conducted or observed by various other media outlets, such as the British
Evo Magazine or
Auto Bild from Germany.
Timing by manufacturers Manufacturers, especially those of
sports cars, conduct their own timing runs and publish these for varying purposes. Manufacturers also lend support to private entities or media outlets.
Timing by private drivers Some lap times are even claimed to have been done during
tourist driving sessions. It is forbidden to race on tourist days. Additionally, there are two speed limits (one in Breidscheid, and one on "Döttinger Höhe") on tourist days. ==Controversies==
