Berlin Motor Books and Michael Schnabl of Motorlegenden hosted on July 3rd, 2026 a themed evening titled “35 Years of the Porsche 964 RS” at Lake Ammersee. The guest of honor for the evening was Roland Kussmaul, the developer of the 964 RS. He became world-renowned as one of the best race engineers. During his 36 years at Porsche, there isn’t a single race car—from the 964 RS to the Carrera GT—that Roland Kussmaul wasn’t involved in.
A Very Special 964
Testing for the 964 RS began in 1990 with the “K47” prototype. Roland Kussmaul has owned this “forerunner” of all 964 RS models since 1993 and brought this one-of-a-kind car to the event. For many Porsche enthusiasts, this was their first chance to see the 964 K47 in person.
In an interview with Berlin Motor Books founder Andreas Gabriel, Roland Kussmaul spoke in detail about the development of the 964 RS.
Porsche Designer Steve Murkett and Jost Capito
Among the guests of honor were Porsche designers Steve Murkett and Jost Capito. The latter helped establish the Carrera Cup together with Herbert Linge starting in 1990 and shared his experiences from that time.
We also have him to thank for the 964 RS, as Capito approached the Porsche Executive Board at the time and advocated for the production of a 911 suitable for motorsports that could also be driven on public roads. Due to a lack of alternatives, many 964 Cup cars were converted for street use. Naturally, this was frowned upon and paved the way for the 964 RS.
As a young designer at Porsche, Steve Murkett was involved in the 964’s design process and contributed his ideas. He attended the event at Ammersee in his own 964 RS, which formerly belonged to Ursula Piech. Among other things, Steve Murkett recounted how he was able to acquire this vehicle. His 964 RS received a very special design for the 10th anniversary of the FLB (Freunde Luftgekühlter Boxermotoren e.V.) and had already participated in Ferdi Porsche’s GP Ice Race.
Special Edition of the 964 Book
After the interviews concluded, Roland Kussmaul and Steve Murkett signed the K47 Edition of the Porsche 964 book, which was published as a limited special edition in a small run of 260 copies.
