Starting in mid May, and running through September, the Porsche Museum will host an exhibit to honor the 50th anniversary of the 917. The exhibit will be named "Colours of Speed — 50 Years of the 917". As part of that exhibit, Porsche will be rolling out a never-before-seen 917 concept study (above) to commemorate the history of the Le Mans champ.
The red and white show car was obviously made as an homage to the Salzberg livery, which won Le Mans overall in 1970. This is specifically a piece of art, and does not have a drivetrain or interior, but it's quite clearly based on 918 Spyder cues, like the center-lock wheels. It's a great combination of old and new, and would be absolutely awesome to see in person to go over those smooth lines. With the FIA WEC converting to a "supercar" standard next year, it would be totally cool to see this thing revived as a race car, but I wouldn't hold your breath.
The Porsche museum had some seriously cool 917s on display when we were there in December, but they will have a total of ten models on display for the anniversary exhibit, which is more than I've ever seen in one place before. The museum claims that the ten Porsches together combine for nearly 7800 horsepower of output, which is seriously awesome.
If you're a big 917 fan, maybe you should plan a trip to Germany for the exhibit. It runs from From 14 May to 15 September 2019 in Stuttgart. Get there.
