Porsche 928 S Steckkonig racing 1983
2017 Techno Classica - Essen (D)

A single racing version of the 928 S was built by Porsche engineer and racing driver Günter Steckkönig. He drove it himself in German endurance races in 1983 and in 1984 the car was entered by the Brumos racing team in the Daytona 24 hour race (in the IMSA GTO class) and finished a creditable 15th overall.
The car is also known as the 928 S Trigema, named after the car's sponsor.
