I stumbled across a bunch of Japanese 964 automotive review content from the early 90s.
RUF 964 BR2 & BR4 content
RUF 964 BR2 video (nearly an hour long)
1993 Supercar Battle video including 964 Carrera RS and RUF 964 BR2
Part 1
Part 2
Part 3
964 Carrera 2 and Carrera 4 review.
Regarding the RUF "electric clutch" mentioned in the video, I found this description online "Elektronik Kupplung System (EKS), which removes clutch pedal and operates clutch automaticaly through gerbox linkage built-in sensors.Other than that,tranmission is just like any other normal manual." Interesting. I had never heard of it before.
I also found this from a Bruce Anderson writeup.

"One of my favorite options on these cars proved to be Ruf's semi-automatic shift system, the optional electronic clutch system.(EKS) which provides the convenience of clutchless driving with out the loss of power normally associated with any of the other clutchless systems which utilize a torque converter.
When we were at Ruf's we drove their second 993 BTR prototype, which has his EKS (Electronische Kupplung System) or in plain English an Electronic Clutch System. Alois Ruf had told me about this system almost two years ago in January 1993 when we met at the Porsche clubs Thunder Tech in Tampa Florida. At the time he was very enthusiastic about the system and I must admit I was not overly impressed with the concept, because I found myself lumping it together with the Sportomatic and Tiptronic transmission of Porsche.
The Ruf cars with the EKS have no clutch pedal and are similar in operation to the transmissions used in the modern Formula 1 cars. The clutch operation is controlled by electronic signals from a computer controlling hydraulic control circuits. The system responds to several different sensors: a gas pedal sensor for throttle position, a torque sensor in the gearshift lever so that it knows when you want to shift, and engine and car speed sensors. From the signals from these different sensors the EKS computer decides when and how to engage or disengage the rather conventional single plate clutch through a hydraulic actuator that moves the clutch throw out bearing. The EKS system is manufactured by the Sachs company and Ruf was their first customer and has helped Sachs to develop the system."
Click the link to read more about it, because the write-up goes into much more detail on behind the wheel performance and operation.
