...on my way to the Rennteam Summer party around Stuttgart area, Mr. Ruf personally. He showed his thumb up to me after a few acceleration runs. From aprox. 90 kph to 190 kph, he moved ahead half a car length and I had additional weight onboard, my wife (60 kg). At a speed over 220 kph, he started to pull away strongly, at 300 kph on the speedo, he was already aprox. 100 m ahead of me. It was a RT12.
