No M BMW's but oddly enough the 3.0 liter non M Z3 Coupe was quicker around N

 

I don't understand what they say...what is the language used???

 

German. You should be able to translate it with Babel Fish: http://world.altavista.com/

 

Excellent site, thanks for the link.

 

I got some more info on the Z3 3.0 vs S2000 as I found the "Sports Auto" issue where they compare S2000, Z3 3.0 and TT Roadster in the same test. On the 'same day, same conditions' the S2000 is slighlty quicker then the Z3 3.0 in the straighline (figures from the article, S2000 vs Z3 3.0):
0- 60kph = 3.0 vs 3.0
0- 80kph = 4.4 vs 4.4
0-100kph = 6.2 vs 6.3
0-120kph = 8.7 vs 8.6
0-160kph = 14.8 vs 15.3
0-180kph = 19.2 vs 19.9
0-200kph = 24.5 vs 27.4

So, as you can see, up to ~140kph there nothing between them but after that things go in the S2000's favour ... more so as speeds increase.

Slalom (18m):
- S2000 = 63.1kph
- Z3 3.0 = 62.6kph
- TT = 62.0kph

Braking 100 - 0kph (cold/warm):
- S2000 = 37.1/36.1m
- Z3 3.0 = 36.7/36.7m
- TT = 36.1/36.4m

Also, they took the cars to the Kleiner Kurs Hokeinheim track and the times were:
- S2000 = 1:18.9
- Z3 3.0 = 1:20.8
- TT = 1:21.3

So it looks like the Z3 3.0 is about the same as the S2000 in the straight-line acceleration but gives a bit in the ultimate track-speed.

ps. This test was done at 24 degrees Celcius (ground = 26).

 

Interesting stats ya brought there bro!
