When the idea to bring motorsport back to Goodwood was first floated in the early 90s by the Earl of March, the plan was to use the historic track. Permitting issues prevented that from happening, so instead a hill climb was planned for the 1.86km driveway that winds its way up Goodwood's grounds.
Although the hill climb component remains the mainstay of the event, two decades on, Lord March has grown the Festival of Speed into what is arguably the largest car culture event in the world, and one of two major motorsport events held each year at the venue. The other is the Goodwood Revival, which recreates the Goodwood Circuit's heydays every autumn.
For the Festival of Speed, which runs from July 12- 14, an eclectic mix of machinery will be exhibited and brought to life on the driveway. While not everyone will be out to shatter the fastest time recorded up the hill - 41.6 seconds set by former German F1 driver Nick Heidfeld driving a West McLaren Mercedes MP4/13 in 1999 - it's a facet of the event that many of the invited participants take rather seriously.
In many cases, drivers and riders will be reacquainted with the vehicles which helped define their careers.
For 2013 that includes Formula 1 heroes of yesteryear, including Alain Prost who will be back behind the wheel of his Renault RE40, Jackie Stewart in a Tyrell 006, and Nelson Piquet in a Brabham BT52. Current F1 driver Jenson Button will do double driving duty in McLaren's forthcoming P1 hypercar and a McLaren M8D Can-Am car, while British motor racing royalty Sir Stirling Moss is scheduled to take the controls of a Mercedes-Benz W196 300 SLR.
New Zealand rally great Rod Millen will drive the Toyota Tacoma that took him to two of five wins at the Pikes Peak International Hill Climb during the 1990s. Although not being driven by Sebastien Loeb, the Peugeot 208 T16 that shattered the Pikes Peak record earlier this month will also be demonstrated.
The on-course competition is just one part of the event. The estate is also home to a 2.5km forest rally stage where World Rally Championship drivers including Mikko Hirvonen and Andreas Mikkelsen will take to the gravel in their modern-day WRC machines alongside rallying legends Carlos Sainz, Waldegard and Hannu Mikkola.
Along with the Moving Motor Show, where more than 20 manufacturers will showcase their products, and the Cartier Style et Lux, where 50 cars will compete in a Concours d'Elegance on the manicured lawns outside Goodwood House, there's an air show, an action sports arena and - new for 2013 - a special parking area inside the event for 300 spectator-owned supercars.
