While seemingly at odds with Porsche's roots as a sports car maker, the Panamera Sport Turismo wagon seems like a great fit in the brand's lineup because it combines style and extra utility. The company has toyed with the concept of offering a long roof variant of an existing model before, though. For example, the firm built a one-off 928 shooting brake called the 928-4 in 1984 as a 75th birthday present for Ferry Porsche. A recent video has put the spotlight on this unique vehicle.
The Porsche Development Centre in Weissach, Germany, started on this birthday present by taking the existing 928 S and stretching it by 9.8 inches (25 centimeters). The designers used the extra space to fit a pair of more comfortable rear seats inside. A higher roof ensured that occupants had enough headroom and forced the installation of a hatchback rather than the standard sloping liftback panel. They also made the B-pillar more upright, so it was easier to get back there. Upfront, fixed headlights replaced the production 928's pop-up units.
Ferry Porsche must have liked the color green because a dark shade covers the exterior and much of the cabin, including the leather trim and carpet. After doing the extensive body modifications, the company left the powertrain the same as the standard 928. The 5.0-liter V8 produced 306 horsepower (228 kilowatts), which allowed for an estimated top speed of 162 miles per hour (260 kilometers per hour).
