Sometimes the presence of a single car merits the journey to Goodwood for the Festival of Speed. But this year if it was being held on the moon I’d investigate the cost of a ticket. The news came in a long press release from Porsche about the 50th anniversary of both the 917 racer and 914 road car. Buried down the bottom somewhere was the line: “At the world’s biggest motor sports meeting, Zuffenhausen’s lightest race car will take on the famous “Hillclimb” after a 51-year break”. And that meant only one thing: the Bergspyder.
