1925–1939: The beginning of the "Nürburg-Ring"

In 1907, the first Eifelrennen race was held on the one-off Taunus circuit, a 117 km (73 mi) made up of public roads starting between the towns of Wehrheim and Saalburg just north of Frankfurt. In the early 1920s, ADAC Eifelrennen races were held on the twisty 33.2 km (20.6 mi) Nideggen public road circuit near Cologne and Bonn. Around 1925, the construction of a dedicated race track was proposed just south of the Nideggen circuit around the ancient castle of the town of Nürburg, following the examples of Italy's Monza and Targa Florio courses, and Berlin's AVUS, yet with a different character. The layout of the circuit in the mountains was similar to the Targa Florio event, one of the most important motor races at that time. The original Nürburgring was to be a showcase for German automotive engineering and racing talent. Construction of the track, designed by the Eichler Architekturbüro from Ravensburg (led by architect Gustav Eichler), began in September 1925.

The track was completed in spring 1927, and the ADAC Eifelrennen races were continued there. The first races to take place on 18 June 1927 showed motorcycles and sidecars, and were won by Toni Ulmen on an English 350 cc Velocette. The cars followed a day later, and Rudolf Caracciola was the winner of the over 5000 cc class in a supercharged Mercedes-Benz "K". In addition, the track was opened to the public in the evenings and on weekends, as a one-way toll road.[1] The entire track consisted of 174 bends (prior to 1971 changes), and averaged 8 to 9 metres (8.7 to 9.8 yd) in width. The fastest time ever around the full Gesamtstrecke was by Louis Chiron, at an average speed of 112.31 km/h (69.79 mph) in his Bugatti.

In 1929 the full Nürburgring was used for the last time in major racing events, as future Grands Prix would be held only on the Nordschleife. Motorcycles and minor races primarily used the shorter and safer Südschleife. Memorable pre-war races at the circuit featured the talents of early Ringmeister (Ringmasters) such as Rudolf Caracciola, Tazio Nuvolari and Bernd Rosemeyer.

1947–1970: "The Green Hell"

After World War II, racing resumed in 1947, and in 1951, the Nordschleife of the Nürburgring again became the main venue for the German Grand Prix as part of the Formula One World Championship (with the exception of 1959, when it was held on the AVUS in Berlin). A new group of Ringmeister arose to dominate the race – Alberto Ascari, Juan Manuel Fangio, Stirling Moss, Jim Clark, John Surtees, Jackie Stewart and Jacky Ickx.

On 5 August 1961, during practice for the 1961 German Grand Prix, Phil Hill became the first person to complete a lap of the Nordschleife in under 9 minutes, with a lap of 8 minutes 55.2 seconds (153.4 km/h or 95.3 mph) in the Ferrari 156 "Sharknose" Formula One car. Over half a century later, even the highest performing road cars still have difficulty breaking 8 minutes without a professional race driver or one very familiar with the track. Also, several rounds of the German motorcycle Grand Prix were held, mostly on the 7.7 km (4.8 mi) Südschleife, but the Hockenheimring and the Solitudering were the main sites for Grand Prix motorcycle racing.

In 1953, the ADAC 1000 km Nürburgring race was introduced, an Endurance race and Sports car racing event that counted towards the World Sportscar Championship for decades. The 24 Hours Nürburgring for touring car racing was added in 1970.

By the late 1960s, the Nordschleife and many other tracks were becoming increasingly dangerous for the latest generation of F1 cars. In 1967, a chicane was added before the start/finish straight, called Hohenrain, in order to reduce speeds at the pit lane entry. This made the track 25 m (27 yd) longer. Even this change, however, was not enough to keep Stewart from nicknaming it "The Green Hell" (German: Die Grüne Hölle) following his victory in the 1968 German Grand Prix amid a driving rainstorm and thick fog. In 1970, after the fatal crash of Piers Courage at Zandvoort, the F1 drivers decided at the French Grand Prix to boycott the Nürburgring unless major changes were made, as they had done at Spa the year before. The changes were not possible on short notice, and the German GP was moved to the Hockenheimring, which had already been modified.

1971–1983: Changes  Relative location of the Nürburgring (around Nürburg, not to scale)

In accordance with the demands of the F1 drivers, the Nordschleife was reconstructed by taking out some bumps, smoothing out some sudden jumps (particularly at Brünnchen), and installing Armco safety barriers. The track was made straighter, following the race line, which reduced the number of corners. The German GP could be hosted at the Nürburgring again, and was for another six years from 1971 to 1976.

In 1973 the entrance into the dangerous and bumpy Kallenhard corner was made slower by adding another left-hand corner after the fast Metzgesfeld sweeping corner. Safety was improved again later on by removing the jumps on the long main straight and widening it, and taking away the bushes right next to the track at the main straight, which had made that section of the Nürburgring dangerously narrow. A second series of three more F1 races was held until 1976. However, primarily due to its length of over 22 km (14 mi), and the lack of space due to its situation on the sides of the mountains, increasing demands by the F1 drivers and the FIA's CSI commission were too expensive or impossible to meet. For instance, by the 1970s the German Grand Prix required five times the marshals and medical staff as a typical F1 race, something the German organizers were unwilling to provide. Additionally, even with the 1971 modifications it was still possible for cars to become airborne off the track. The Nürburgring was also unsuitable for the burgeoning television market; its vast expanse made it almost impossible to effectively cover a race there. As a result, early in the season it was decided that the 1976 race would be the last to be held on the old circuit.

Niki Lauda, the reigning world champion and only person ever to lap the full 22.835 km (14.189 mi) Nordschleife in under seven minutes (6:58.6, 1975), proposed to the other drivers that they boycott the circuit in 1976. Lauda was not only concerned about the safety arrangements and the lack of marshals around the circuit, he also did not like the prospect of running the race in another rainstorm. Usually when that happened, some parts of the circuit were wet and other parts were dry, which is what the conditions of the circuit were for that race. The other drivers voted against the idea and the race went ahead. Lauda crashed in his Ferrari coming out of the left-hand kink before Bergwerk after a new magnesium component (lighter but more fragile than aluminum used until then) on his Ferrari's rear suspension failed. He was badly burned as his car was still loaded with fuel in lap 2. Lauda was saved by the combined actions of fellow drivers Arturo Merzario, Guy Edwards, Brett Lunger, Emerson Fittipaldi and Harald Ertl.

The crash also showed that the track's distances were too long for regular fire engines and ambulances, even though the "ONS-Staffel" was equipped with a Porsche 911 rescue car, marked (R). The old Nürburgring never hosted another F1 race again, as the German Grand Prix was moved to the Hockenheimring for 1977. The German motorcycle Grand Prix was held for the last time on the old Nürburgring in 1980, also permanently moving to Hockenheim.

By its very nature, the Nordschleife was impossible to make safe in its old configuration. It soon became apparent that it would have to be completely overhauled if there was any prospect of Formula One returning there - the Nürburgring's administration and race organizers were not willing to provide the enormous expense of providing the number of marshals needed for a Grand Prix - up to six times the amount that most other circuits needed. With this in mind, in 1981 work began on a 4.556 km (2.831 mi)-long new circuit, which was built on and around the old pit area.

At the same time, a bypass shortened the Nordschleife to 20.832 km (12.944 mi), and with an additional small pit lane, this version was used for races in 1983, e.g. the 1000km Nürburgring endurance race, while construction work was going on nearby. During qualifying for that race, the late Stefan Bellof set a lap of 6:11.13 for the 20.8 km (12.9 mi) Nordschleife in his Porsche 956, or 199.8 km/h (124.1 mph) on average. This lap held the all-time record for 35 years (partially because no major racing has taken place there since 1984) until it was surpassed by Timo Bernhard in the Porsche 919 Hybrid Evo, which ran the slightly longer version of the circuit in 5:19.546- averaging 233.8 km/h (145.3 mph) on 29 June 2018.

Meanwhile, more run-off areas were added at corners like Aremberg and Brünnchen, where originally there were just embankments protected by Armco barriers. The track surface was made safer in some spots where there had been nasty bumps and jumps. Racing line markers were added to the corners all around the track as well. Also, bushes and hedges at the edges of corners were taken out and replaced with Armco and grass.

The former Südschleife had not been modified in 1970–1971 and was abandoned a few years later in favour of the improved Nordschleife. It is now mostly gone (in part due to the construction of the new circuit) or converted to a normal public road, but since 2005 a vintage car event has been hosted on the old track layout, including part of the parking area.[2]

The new track was completed in 1984 and named GP-Strecke (German: Großer Preis-Strecke: literally, "Grand Prix Course"). It was built to meet the highest safety standards. However, it was considered in character a mere shadow of its older sibling. Some fans, who had to sit much farther away from the track, called it Eifelring, Ersatzring, Grünering or similar nicknames, believing it did not deserve to be called Nürburgring. Like many circuits of the time, it offered few overtaking opportunities.

Prior to the 2013 German Grand Prix both Mark Webber and Lewis Hamilton said they liked the track. Webber described the layout as "an old school track" before adding, "It's a beautiful little circuit for us to still drive on so I think all the guys enjoy driving here." While Hamilton said "It's a fantastic circuit, one of the classics and it hasn't lost that feel of an old classic circuit."[3]

To celebrate its opening, an exhibition race was held on 12 May. The 1984 Nürburgring Race of Champions featured an array of notable drivers driving identical Mercedes 190E 2.3–16's: the line-up was Elio de Angelis, Jack Brabham (Formula 1 World Champion 1959, 1960, 1966), Phil Hill (1961), Denis Hulme (1967), James Hunt (1976), Alan Jones (1980), Jacques Laffite, Niki Lauda (1975, 1977)*, Stirling Moss, Alain Prost*, Carlos Reutemann, Keke Rosberg (1982), Jody Scheckter (1979), Ayrton Senna*, John Surtees (1964) and John Watson. [Drivers marked with * won the Formula 1 World Championship subsequent to the race]. Senna won ahead of Lauda, Reutemann, Rosberg, Watson, Hulme and Jody Scheckter, being the only one to resist Lauda's performance who – having missed the qualifying – had to start from the last row and overtook all the others except Senna.[4][5] There were nine former and two future Formula 1 World Champions competing, in a field of 20 cars with 16 Formula 1 drivers; the other four were local drivers: Klaus Ludwig, Manfred Schurti, Udo Schütz and Hans Herrmann.

Besides other major international events, the Nürburgring has seen the brief return of Formula One racing, as the 1984 European Grand Prix was held at the track, followed by the 1985 German Grand Prix. As F1 did not stay, other events were the highlights at the new Nürburgring, including the 1000km Nürburgring, DTM, motorcycles, and newer types of events, like truck racing, vintage car racing at the AvD "Oldtimer Grand Prix", and even the "Rock am Ring" concerts.

Following the success and first world championship of Michael Schumacher, a second German F1 race was held at the Nürburgring between 1995 and 2006, called the European Grand Prix, or in 1997 and 1998, the Luxembourg Grand Prix.

For 2002, the track was changed, by replacing the former "Castrol-chicane" at the end of the start/finish straight with a sharp right-hander (nicknamed "Haug-Hook"), in order to create an overtaking opportunity. Also, a slow Omega-shaped section was inserted, on the site of the former kart track. This extended the GP track from 4.556 to 5.148 km (2.831 to 3.199 mi), while at the same time, the Hockenheimring was shortened from 6.823 to 4.574 km (4.240 to 2.842 mi).

Both the Nürburgring and the Hockenheimring events have been losing money due to high and rising Formula One license fees charged by Bernie Ecclestone and low attendance due to high ticket prices;[6][7][citation needed] starting with the 2007 Formula One season, Hockenheim and Nürburgring alternated in hosting the German GP.

In Formula One, Ralf Schumacher collided with his teammate Giancarlo Fisichella and his brother at the start of the 1997 race which was won by Jacques Villeneuve. In 1999, in changing conditions, Johnny Herbert managed to score the only win for the team of former Ringmeister Jackie Stewart. One of the highlights of the 2005 season was Kimi Räikkönen's spectacular exit while in the last lap of the race, when his suspension gave way after being rattled lap after lap by a flat-spotted tyre that was not changed due to the short-lived 'one set of tyres' rule.

Prior to the 2007 European Grand Prix, the Audi S (turns 8 and 9) was renamed Michael Schumacher S after Michael Schumacher. Schumacher had retired from Formula One the year before, but returned in 2010, and in 2011 became the second Formula One driver to drive through a turn named after them (after Ayrton Senna driving his "S for Senna" at Autódromo José Carlos Pace).

Alternation with Hockenheim

In 2007, the FIA announced that Hockenheimring and Nürburgring would alternate with the German Grand Prix with Nürburgring hosting in 2007. Due to name-licensing problems, it was held as the European Grand Prix that year. In 2014, the new owners of the Nürburgring were unable to secure a deal to continue hosting the German Grand Prix in the odd-numbered years, so the 2015 and 2017 German Grands Prix were cancelled.

In July 2020, it was announced that after seven years, the race track would be an official Formula One Grand Prix with the event taking place from 9 to 11 October 2020. This race was called the Eifel Grand Prix in honour of the nearby mountain range, meaning the venue held a Grand Prix under a fourth different name having hosted races under the German, European and Luxembourg Grands Prix titles previously.[8] That race was won by Lewis Hamilton, who equalled Michael Schumacher's record of wins.

Fatal accidents

While it is unusual for deaths to occur during sanctioned races, there are many accidents and several deaths each year during public sessions. It is common for the track to be closed several times a day for cleanup, repair, and medical intervention. While track management does not publish any official figures, several regular visitors to the track have used police reports to estimate the number of fatalities as between 3 and 12 in a full year.[9] Jeremy Clarkson noted in Top Gear in 2004 that "over the years this track has claimed over 200 lives".[10][unreliable source?]
