oh yes definately, a csl is a low 13-high 12 car as standard, but i do think the 335d is a match over the standing quarter with a e46 m3, as i have never seen one beat a 13.5 and i know a 335d is capable of this time in standard trim.
Even so, a low 13 to the ton is far from being shy!!
there is some technique to launching an auto, but your right it would be far more challenging launching a 365bhp csl squeeze!!
i once got a 16.6 out of a 318is LOL, thats not bad really for a 140bhp 1.9 bm lol
