1932–1938

Originally called "Dreieckskurs" (triangle course), the Hockenheimring was built in 1932. The man behind it is Ernst Christ, a young timekeeper who felt that a racing track should be built in his hometown of Hockenheim. He submitted the plans to the mayor and they were approved on Christmas day, in 1931. This first layout of the track was around twelve kilometres long and consisted of a large triangle-like section, a hairpin in the city and two straights connecting them.

1938–1965

In 1938, the circuit dramatically shortened, from twelve kilometres down to just over seven and a half, and the Ostkurve corner, which lasted until 2001, was introduced for the first time. In that year, the track was also renamed to "Kurpfalzring". The track was damaged by tanks during World War II. After the war, the track was repaired, and renamed to "Hockenheimring". Former DKW and NSU factory rider and world record setter Wilhelm Herz became the manager of the track in 1954 and promoted the track successfully; Grand Prix motorcycle racing events were held, with the German motorcycle Grand Prix alternating between the Hockenheimring and other tracks. This version of the circuit was just over seven and a half kilometres long and consisted of the original two long straights, with the Ostkurve in the forest and the original hairpin inside Hockenheim joining them together.

1965–2001

In 1965, when the new Autobahn A 6 separated the village from the main part of the track, a new version of Hockenheim circuit was built, with the "Motodrom" stadium section, designed by John Hugenholtz, who also designed Suzuka. After Jim Clark was killed on 7 April 1968 in a Formula 2 racing accident, two fast chicanes were added and the track was lined with crash barriers in 1970. A small memorial was placed near the first chicane (which was named after him), at the site of his accident. In 1982, another chicane was added at the Ostkurve (east curve), after Patrick Depailler was killed there in 1980, and the first chicane was made slower as well. For the 1992 German Grand Prix, the Ostkurve was changed yet again, from a quick left turn into a more complex right-left-right chicane, after Érik Comas crashed there in 1991. The second chicane was renamed after Ayrton Senna, after his death at the 1994 San Marino Grand Prix.

This version used to be quite large, with a very long and very fast section going through forests essentially consisting of four straights of roughly 1.3 km (0.81 mi), separated by a chicane sequence, followed by a more tight and twisty "stadium" section (so called because of all the grandstands situated there) named Motodrom. This made the setting up of racing cars difficult, since a choice had to be made – whether to run low downforce to optimize speed through the straights and compromise grip in the stadium section, or, run more downforce to optimize grip through the stadium section and compromise speed on the straights. The long track length also meant that a typical Formula One race had only 45 laps, limiting the spectators' experience of the race to only that many passes through the stadium.

During the mid-1980s "turbo era" of Formula One where fuel was restricted to either 220 (1984–1985), 195 (1986–1987) or 150 (1988) litres for races for the turbo powered cars, Hockenheim also saw drivers, including World Champion Alain Prost, at times fail to finish due to simply running out of fuel near the end of the race. Prost ran out at the end of the 1986 race, pushing his McLaren towards the line before giving up. He was placed 3rd when he ran dry and was eventually classified 6th, gaining a valuable championship point that would help him with his second World Championship.

Many problems came to light during the 2000 German Grand Prix, which was won by Brazilian driver Rubens Barrichello from having started 18th on the grid. The race finished in changeable weather conditions, with pouring rain in the stadium sector and almost completely dry forest straights. All the overtaking moves that took place during the race were in the chicanes of the forest sector, meaning hardly any spectators saw most of the best action. Midway through the race, a former Mercedes-Benz employee, who had been dismissed, breached the track's security barriers on the first forest straight, showing vulnerable security facilities in the forest and leading to the deployment of the safety car that neutralized a comfortable lead for the two Mercedes-powered McLarens. Later on, French driver Jean Alesi collided with Brazilian Pedro Diniz in the braking zone for the third chicane and his car spun uncontrollably down the track, which caused him to suffer dizziness for three days.

These events prompted much protest from the FIA to greatly improve spectator viewing, safety, and security at the track, claiming that the track was no longer suited to modern Formula One racing.

2002 redesign

In the early 2000s, F1 officials demanded the 6.823 km (4.240 mi) track be shortened and threatened to discontinue racing there, threatening to relocate to other tracks such as the EuroSpeedway Lausitz and sites in Asia. The state government of Baden-Württemberg secured the financing for the redesign by Hermann Tilke for the 2002 German Grand Prix. The stadium section remained mostly intact, despite a new surface and a tighter Turn 1 ("Nordkurve"). However, the circuit was dramatically shortened, with the long, forested straights section chopped off in favour of more tight corners. More than half of the first straight and almost all of the straight between the Ostkurve and Senna chicane were cut and the rest was connected with a new long straight called the "Parabolika", with a small kink being added between the first straight and the new one. A small right-left-right complex was added to the remaining part of the final straight, with a new grandstand overlooking it. In an extremely controversial move, the old forest section was torn up and replanted with trees, eliminating any chance of using the old course either for future F1 events or for historic car events.

There was and still remains a great deal of criticism of the track redesign, in terms of ruining the previous unique technical challenges of the old Hockenheim circuit and delivering a new homogenised "assembly line" circuit without the character of the previous layout, whilst being beset by the perceived problems of other Tilke circuits.^[3] Several drivers and team principals, including Ron Dennis, Jarno Trulli and Juan Pablo Montoya, criticised the changes and stated their preference for the old circuit.^[4]

The change in the track layout also saw the installation of a new memorial to Jim Clark. This is located at the outside of the current track's turn 2, where the old track continued out into the forests, and the new shortened track turns to the right.^[5]

The new track has a seating capacity of 120,000, due to new large grandstands sponsored by Mercedes-Benz. The complex also features a quarter-mile track for drag racing. It hosts one of the largest drag racing events in Europe, known as the NitrOlympx, and was one of the last Top Fuel circuits to race to 0.25 mi (0.40 km) before the FIA switched the nitro categories to the now-recognised 1,000 ft (300 m) distance in 2012.
