It was created to mark 70 years since the first production Porsche was introduced.
Released in 1948, the two-door Porsche 356 was the first car manufactured by the German company. This historic car is placed on one of the tips of the seven-pointed star, with five other Porsches from the past 70 years attached to other tips.
The sculpture features two other notable historic Porsches: the 917, an endurance racer driven by Steve McQueen in the film Le Mans, and the 959, which was a winner of the 1987 Paris Dakar rally.
Alongside these vehicles are three modern Porsches: the 918 Spyder, which is a hybrid road car made in 2015; the 919 Le Mans Prototype from 2015; and the 911R, a road car introduced in 2016, which is included to represent up-to-date Porsche design.
Weighing six tonnes in total, the cars are all supported on the narrow pylon, which is only 98 millimetres wide at the ground. This 21-tonne structure is constructed from hexagonal tapered tubes that are fabricated from laser-cut steel plate.
"The geometry is based on a regular truncated octahedron – this shape giving positions to display all six cars, with a stem at the bottom and a spire on top," said Judah.
Judah has been commissioned to create a sculpture at the festival each year since 1999. Last year's piece featured five Formula One cars to represent key moments in the career of Bernie Ecclestone.
