Special classes 2023 at ZCCA – 125 Years of ACS

Attractive ACS booth at Older Classics on June 11, 2023 at Valley Kemptthal:

The Beast is coming to the Valley!

It is considered the race car of the century and drove everything into the ground in 1970 and 1971. In these two years, the Porsche 917 won the prestigious 24 hours of Le Mans - a priceless success at the time for the still small sports car manufacturer Porsche.

As fast as no other!

Its 600 hp 5-liter twelve-cylinder engine was unbeatably fast. At Le Mans, for example, it reached a top speed of over 380 km/h at the end of the six-kilometer Hunaudières - the Ferraris 512 only saw its tail in each case. And because the Porsche 917 was invincible at that time, new regulations were created for the racing sports car world championships. This prompted Porsche to equip the 917 with two turbochargers in the future and to enter it in the American CamAm series. Upgraded in this way, the V12 power unit of the Porsche 917 delivered a sturdy 800 - 1100 hp and won almost all races in 1973 and all without exception in 1974!

During this time, Jo Siffert drove the 917 for John Wyder's racing team in the well-known Gulf Racing livery, in addition to his Formula 1 commitments as a Porsche works driver. His victories with Brian Redmann at world championship races such as Spa, Watkins Glen, Zeltweg, Buenos Aires and Brands Hatch were numerous.
