Gallery: The best of FOS Friday

The 70th Anniversary celebrations for Porsche continued with a display at the front of the house of cars, music and fireworks.

It wasn't the only display centring on the house on Friday. Renowned trials bike rider Dougie Lampkin put on a show on the roof of the house. Back on terra firma, the Borg-Warner Trophy – an impressive 1.6-metre tall trophy awarded to the winner of the Indianapolis 500 – made an appearance on the front steps. It's the first time the trophy has been to Europe, and only the second time it has left the USA, in 82 years.

There was lots of action on the hillclimb too, with F1 cars from past and present taking part for the first time this year.

Some of the contenders for Sunday's timed runs were putting down early markers too. Andy Reid driving the BAC Mono headed the time sheets, followed by Peter Dumbreck in the electric NIO EP9.

Slightly slower were two autonomous efforts. A classic Mustang converted by Siemens took a gentle drive up the hill, along with the completely unmanned Roborace car.

The Bonhams auction saw action of a different kind. An Aston Martin DB4GT Zagato that has been in one owner's collection for 47 years sold for £10m, while a BMW 507 owned from new by John Surtees sold at £3.8m.

It's been an eventful day, as you can see from the gallery below.
