Check out this extremely yellow one-off Porsche 911 Speedster ‘Sonderwunsch’

German has a word for everything, and ‘Sonderwunsch’ is your word of the day: it means ‘special request’. For example: “Dear Porsche factory, please would you build me a chopped-top Speedster based on a 993 with a 300bhp engine in the back? Grazie. PS my favourite colour is yellow.”

Welcome to a one-off 993 Speedster, commissioned three years ago by Italian-born industrial designer and architect Luca Trazzi. The 993 Speedster is something of a missing link for Porsche: though it made a factory run of Speedsters for the 911s that came before and after it, the 993 largely missed out.

Only two have been built before: a narrow-body automatic for Ferdinand Alexander Porsche completed in 1995, and a widebody 4S-based example built for Jerry Seinfeld in 2001. Now they have a sibling, powered by a 300bhp air-cooled 3.8-litre flat-six from the 993 Carrera RS.

Trazzi’s car was originally a 1994-model 993 Cabriolet, but it’s had a very thorough reworking from the Sonderwunsch team. It sports a shorter windscreen, the classic bulbous rear deck and 1960s-inspired conical door mirrors. New headlamps feature the four-dot LED running lights from modern Porsches.

The Otto yellow/black bodywork theme is continued onto the pinstriped 18in Turbo rims, and on the instrument cluster inside. No LED tachometers there… though the interior has been reworked to feature Apple CarPlay. Now, you wouldn’t go to that trouble if it was going to sit in a bunker for the rest of its days, would you? So hopefully, Luca plans to drive his Speedster. Well, the weather in Italy smiles on an al fresco sports car… though there is a sweptback roof in case he ever fancies testing his one-off on a British B-road.

Porsche says this won’t be the last Sonderwunsch it takes on – new requests from interested clients will be handled either by the individualisation skunkworks of Porsche Exclusive Manufaktur, or Porsche Classic. Driving dynamics can even be tweaked by the RS team at Weissach.

So, that begs a question really: what’s your ultimate Porsche one-off? Got a special request for the ultimate marriage of Porsche beauty, power and originality? A Carrera GT V10 in the back of a 996 perhaps? Let us know your suggestions below.
