The Hockenheimring was built in 1932, conceived by Ernst Christ, a local timekeeper who proposed the project to the Hockenheim town council. The original layout was approximately twelve kilometres long, forming a large triangular course. In 1938 the circuit was shortened to just over seven and a half kilometres, introducing the Ostkurve corner that would define the circuit for decades.
Following World War II, the circuit was repaired and reorganised under the management of Wilhelm Herz, a former DKW and NSU factory rider and world speed record holder, who took charge in 1954. Herz actively promoted the circuit for Grand Prix motorcycle racing, and German motorcycle Grand Prix events were established at Hockenheim, alternating with other venues. During this period the circuit featured two very long, essentially flat straights through forested land on either side of the Ostkurve, connected to a tighter stadium section known as the Motodrom at the other end.
In 1965, construction of the new Autobahn A6 cut through land adjacent to the track, requiring a redesign of the circuit that introduced the Motodrom stadium section, designed by John Hugenholtz, the same architect responsible for Suzuka. This version of the circuit became the configuration most associated with Grand Prix racing at Hockenheim for the following three and a half decades.
The 6.823 km layout in use from 1965 to 2001 was one of the most demanding and controversial on the Grand Prix calendar in any series. It featured four very long straights through forest, each approximately 1.3 km, separated by chicane sequences. This made the circuit extraordinarily fast on the straights but technically challenging through the chicanes, and created a setup dilemma: running low downforce maximised straight-line speed but compromised grip in the stadium section, while running more downforce reversed the compromise.
Following the death of Formula One driver Jim Clark in a Formula Two accident at Hockenheim in April 1968, two fast chicanes were added to the forest section and the track was lined with crash barriers in 1970. Further safety modifications followed after Patrick Depailler was killed at the Ostkurve in 1980, leading to an additional chicane in 1982. The second chicane was subsequently named after Ayrton Senna following his death at the 1994 San Marino Grand Prix.
Grand Prix motorcycle racing moved permanently to the Hockenheimring after the German motorcycle Grand Prix left the Nürburgring in 1980. Hockenheim hosted the German motorcycle Grand Prix in subsequent years, with the long, flat straights rewarding outright top speed while the Motodrom stadium section created close racing that spectators in the grandstands could follow directly.
In the early 2000s, Formula One officials demanded that the circuit be shortened, threatening to remove Hockenheim from the calendar unless major changes were made. The state government of Baden-Württemberg financed a redesign by Hermann Tilke for the 2002 German Grand Prix. The forest section was eliminated entirely — the old straights were torn up and replanted with trees — and the remaining circuit was connected with a new section called the Parabolika, reducing the track length from 6.823 km to approximately 4.574 km.
The redesign was deeply controversial. Many drivers, team principals, and fans considered the new layout a homogenised, character-free replacement for one of the most distinctive circuits in motorsport. The long forest straights that had defined Hockenheim were gone permanently, with no prospect of using the old course for any future events.
By the time of the 2002 redesign, the German motorcycle Grand Prix had already moved to other venues. The Hockenheimring's role in hosting premier-class motorcycle racing belonged to the era of the original long circuit. The last German motorcycle Grand Prix held on the old Nürburgring was in 1980; Hockenheim subsequently served as the German venue for motorcycle racing through the decades that followed, before the event found other homes.
The Hockenheimring's importance to German motorcycle Grand Prix history lies in the era of the long circuit, when the combination of outright straight-line speed and the physically enclosed Motodrom stadium section created a spectacle unlike any other venue on the calendar. The circuit's role in nurturing German motorsport — and its management by a former factory motorcycle racer in Herz — gave it a particular connection to motorcycle racing culture that extended beyond its use as a Formula One venue. The destruction of the forest section in 2002 ended any possibility of experiencing that original character, making the pre-2002 Hockenheimring a purely historical reference in the context of German motorcycle Grand Prix racing.
