DJ and self-confessed petrolhead Chris Evans was among the big crowds lapping up the action at the Goodwood Revival today.
He and wife Natasha watched excitedly as cars in the Fordwater Trophy put on a specatacular show.
Meanwhile motorsport great Sir Stirling Moss and Lady Susie were also cheering on the drivers in a packed racing programme as the famous Goodwood circuit near Chichester went back in time to its 1950s and 1960s heyday.
Other well-known names enjoying being part of what resembles a giant film set include legendary racers Sir Jackie Stewart, John Surtees and Tony Brooks, Olympian Sir Chris Hoy, comedian Rowan Atkinson, TV chef James Martin and Pink Floyd drummer Nick Mason.
The day started sunny, but rain is expected later in the afternoon and that could make conditions very tricky for those on the grid for the final few races of the meeting.
The Settrington Cup is set to be a strangely silent affair as it features a grid of Austin J40 pedals cars piloted by children.
Another part of the unique Revival celebrating pedal power is the daily peloton of cyclists taking to the track to mark 100 years of the Tour de France.
Getting behind the wheels at the Revival are ex-F1 stars Mark Blundell and Derek Daly, touring car aces John Cleland and Anthony Reid and Le Mans winners Tom Kristensen, Derek Bell and Jochen Mass.
Ferrari favourite Jean Alesi flew in to drive a 1963 Ferrari 250 GTO and the modern grand prix scene was represented by Red Bull F1 team principal Christian Horner and design chief Adrian Newey.
They are normally on the pit wall watching their drivers perform in grands prix, but at the Revival both are in the hot seat - Horner in a 1960 Ferrari 250 GT and Newey in his own 1965 Ford GT40.
Tens of thousands of spectators are lining the track, the majority of whom are in period dress. Dad’s Army are on parade, land girls mix with RAF officers and glamorous Audrey Hepburn lookalikes walk arm-in-arm with country gents in tweed and trilbies.
Period music is getting people dancing, children are enjoying a traditional funfair and there is even a Tesco supermarket from the 1960s where brands from yesteryear, complete with authentic packaging, can be bought.
Attendance for the sold-out three-day event near Chichester is expected to match last year’s figure of 146,000 and enthusiasts have travelled from all over the world to enjoy the unique Revival atmosphere and see a mouthwatering array of priceless historic racing cars go wheel to wheel.
Highlight of the weekend is expected to be this afternoon’s two-driver one-hour RAC TT Celebration featuring closed-cockpit GT cars such as Ferraris, Aston Martins and Jaguars worth more than £150m.
There is also plenty to see in the air today, with Battle of Britain Memorial Flight displays featuring Spitfires and Hurricanes, a rare Canberra, plus a special commemoration of the 70th anniversary of the wartime Dambusters raid with an evocative flypast by a Lancaster bomber (subject to weather).
