View Full Version : Reinterpreting a classic - how Hockenheim was transformed

Hockenheim first hosted a world championship race in 1970, but even before that it had earned a reputation as a home for the brave, a circuit for the daring. It was a flat-out blast through the forest; a track where, as two-time Hockenheim winner Gerhard Berger put it, "your foot keeps on wanting to come off the accelerator".
Over the decades small modifications were made to the breath-taking blend of long straights and sweeping bends, but the circuit retained its fundamental character up until the turn of the century, when radical revisions were implemented.
The old circuit, while unique and fondly remembered, was not without limitations: its layout was fast and narrow - with limited run-off - and not particularly conducive to overtaking. At 6.8 kilometres, it was felt to be too long - particularly as a small spectator capacity meant it was prohibitively expensive to run. The circuit in general needed to modernise. Bosses were therefore at a crossroads, striving to update the track while also retaining the characteristics which had come to define it as a driver's favourite, and a test not just of machine and skill but also character.
"The Hockenheimring has always been a magnet of attraction for the area," explains the circuit's CEO Georg Seiler. "Having recognised this factor, and the competition of new, modern race tracks - in Germany and abroad - the decision was made to finance a complete modernisation in 2002 and '03.
"The main goals were: to shorten the track from 6.8km to 4.5km, now standard for modern F1 tracks; to improve conditions for overtaking; and to keep the circuit's main characteristics."
There were two prerequisites needed before any construction could be considered - the consent of the citizens of the city of Hockenheim, and the financial support of the state of Baden-Württemberg.
"Both greatly benefited financially from [hosting F1]," Seiler says. Eighty per cent of the populace lent their support, and the decision was therefore made to jointly finance the new enterprise.
The task itself fell to renowned circuit designer Hermann Tilke, who was approached, says Seiler, "for three reasons: experience, expertise and vision."
That vision, however, would change over time as various considerations and restrictions came into play.
"The old Hockenheimring was a fast-lane track with long straights," Tilke explains. "There was something very special about it, about how rare its layout was, so we wanted therefore to keep as much as possible of the old track.
"The original idea was just to broaden the existing track according to current safety regulations, and to keep the track to its original length. At that time the restrictions and possibilities the site offered were not clear however and the idea eventually proved unfeasible.
"Firstly, there was a doctrine to save forests, and to even merge the enclosed section of trees with the adjacent forest, so chopping down trees had to be kept to an absolute minimum. That produced a second constraint: we had to use as little area as possible for the new track. Then of course we had to factor in financial resources and a tight timescale.
"The task became to design something new, on the existing site, and make it more interesting and accessible for visitors, all without impacting upon the woodland. Today's track layout is the result of that intense idea exchange and development process, conducted alongside the Hockenheim management."
The revamp was also the product of extensive simulation work, and consultation with the men who would actually race on the new circuit. Michael Schumacher, who at the time was in the early stages of his record-breaking run of five straight world championship crowns with Ferrari, was among those to have an input.
"We have an in-house simulation programme and therefore conducted virtual tests of our new design, which at that point existed only on paper and as CAD [computer-aided design] files," Tilke explains. "There was also an exchange of views and ideas with drivers including Schumacher, because he was chairman of the Grand Prix Drivers' Association at the time. We mainly discussed safety concerns, but they also had a few inputs into the design phase."

Finally, a plan was settled - the famous
