Bonhams will offer one of the five prototype Porsche 928 Club Sports built for the company’s factory racing drivers.
Porsche built five 928 Club Sport prototypes for the marque’s star list of factory drivers – Derek Bell, Jochen Mass, Hans Stuck, Bob Wollek and Jacky Ickx – to use as company cars. All of them were white and had left-hand drive.
This 1987 example, the last of the five, was given to five-time Le Mans winner Bell in 1988, and the story goes that the time lapse was because he was initially reluctant to take delivery of the car due to it having left-hand drive. A while later he asked about a white 928 sitting under a tree at Porsche, to be told, ‘Oh, that’s your 928.’ So he brought it home, but apparently Bell complained to Porsche that it was incorrectly geared because he could hit the rev limiter in top gear on the autobahn – 297km/h, or about 185mph…
The production Clubsport arrived in 1988, weighing around 200kg less than the S4 thanks to the removal of much of the sound-deadening material and some electrical equipment and wiring, though electric windows remained. They had only one door mirror while the prototypes retained the pair. The springs were around 10% stiffer and the 5.0-litre motor received camshafts with an extra 1mm of lift. That and a revised ECU raised power by 10bhp to 330bhp at 6200rpm, transmitted through a five-speed manual gearbox (with a shorter gearlever) and a limited-slip differential.
Hans Stuck’s car today forms part of a Porsche collection in the Netherlands, while that of Jochen Mass is believed to be in Scandinavia. Bell kept hold of his – chassis 014 – until 2005, in tandem with his beloved 924 Carrera GT, which means that of the five drivers he kept his 928 the longest. It’s been in a Belgian collection since 2009, and is estimated to fetch €225,000-265,000.
