This particular episode just showed short clips from the Motorvision Trackteile archives. This episode was focused mainly on the Z4 Coupe.

Here's a few select results from the compiled Motorvision Track test results:

11. BMW Z4 3.0i -19,6
25. Mazda RX8 -19,84
29. BMW Z3 3.0 -19,92
37. VW Golf R32 -20,11
46. Mercedes SLK 350 -20,27
50. Corvette C6 -20,3
51. Mercedes C320 Sportcoupé -20,31
69. Chrysler Crossfire SRT6 (Winterr.) -20,5
70. Mercedes SL 55 AMG (2005) -20,52

BTW: Motorvision's Track Test Times are Bullshit. German magazine "SPORT AUTO" lists a Hockenheim Short Circuit "best time" comparison between the Z4 3.0i and the SRT6 as follows:

Track : Hockenheim Short
Crossfire SRT-6 : 1:17.4
RoadsterZ4 3.0i : 1:18.1

I trust SPORT AUTO much more than Motorvision that's for sure...
