This year's featured marque at the Goodwood Festival of Speed (3-5 July) is Audi as the Ingolstadt-based automaker is celebrating its 100th birthday. To commemorate the anniversary, Lord March, who hosts the festival at his back-yard 12,000-acre West Sussex estate, commissioned the creation of massive sculpture that features two cars from Audi's history, the iconic 1937 Auto Union streamliner and the just launched R8 V10 sports car suspended in the air, at either end of the 'swoosh' of tire tracks.

Designed by the Gerry Judah, Lord March's creative collaborator, the sculpture weighs in at a total of 40 tonnes or the equivalent of 40 small family cars and it took two 100-tonne cranes to raise the monument and about four weeks for 12 men to fabricate, build and install it in front of the Goodwood house.

"I drew about 20 ideas and some had elaborate bridges with vaulted arches but somehow they didn't have quite the right style," said Judah. I then had a flash of inspiration and designed this 'swoosh' with a car at either end to represent Audi's 100-year history.

"It's made entirely of steel and although the design looks simple, it's actually extremely complex, because the structure has to be rigid and completely balanced without the need for hundreds of supporting props."
