Glad you're enjoying the 3.5!! Same engine in my CLS and it will seriously shift. Unquestionably rapid from 0-60, but completely agree flooring it (where legally permitted) when already at UK motorway speeds it seems to hit 3 figures almost in the blink of an eye. Definitely much more power at the top end than my previous M112 3.2 CLK.
The sound is beautiful too, especially over 3000rpm as was mentioned previously, the sort of burbling noise that you would expect from a V8. Surprised there are so few of these around (I think I am the only CLS350 owner on the CLS owners register on this forum).
On the fuel consumption you are doing much better than me though. I haven't seen 30 yet, although until a week or two ago I was running on duff cam sensors and a failing oxygen sensor, already seeing improvements so hopefully 30+ should be achievable on a steady motorway cruise, even with the heavier body/bigger size of the CLS. I could easily see 37 on my CLK so will be disappointed if the technology of the CGI can't deliver early 30s.
