Porsche unveiled the Panamera Sport Turismo at the 2017 Geneva Motor Show. The shooting brake is the latest addition to the company’s product range – but the first prototypes of this design could be found in Zuffenhausen more than 30 years ago.

The Panamera Sport Turismo is a new body variant for the Panamera. For Porsche, it is a step forwards into a new segment. A coupé with a hatchback – is this completely new territory for the sportscar manufacturer from Zuffenhausen? Not quite.

The Panamera Sport Turismo is the first series shooting brake from Porsche – that much is true. But the initial ideas and prototypes were developed more than 30 years ago. In addition to an extended Porsche 911 S variant from 1970, evidence can be found in two Porsche 928 models. One is the four-door 928 H50 concept from 1987, while the other is the 928-4: a four-seater prototype with a shooting brake body from 1984.

A look into the museum’s secret storehouse

Created by the Porsche Development Centre in Weissach, this was a version of the 928 S that was extended by 25 centimetres. The longer wheelbase and the modifications to the B-pillar and door frame meant that passengers in the rear had an extra 20 centimetres of legroom – attributes that can now be found in the new Panamera Sport Turismo in more or less the same form. Some additional features of this one-off creation were the projector headlights, hatchback design, leather interior and green tinted windows.

The car was presented to Ferry Porsche on September 19, 1984 as a gift on his 75th birthday. It is now held by the Porsche Museum.
