I forget what percentage we lose to the drivetrain...I think somewhere in the neighborhood of 15%. I'm sure someone else can correct me.
If so, either your motor is built very well or Mercedes is undercutting their "actual" performance figures again. I believe the latter to be true. Afterall, one of their goals was to avoid the GG tax on this vehicle. I think HP and fuel economy play a role in that. Again, I'm not entirely sure.
Congrats FlyC63.
By the way, where are you getting your motor tuned?
2012 S63 (PP) 537 rwhp 611 tq
2012 CLS 63 (standard) 470 rwhp 477 tq
2009 C63 (modded) 447 rwhp 400 tq
I'll be getting the Singh Autosport tune at Eurorev in Inglewood.
Keep us posted and thanks for the figures.
As more and more owners tune their motors, we'll find out if the M157 can produce similar numbers to that S63 with PP.
please give us some feedback after you tune. i think you can squeeze more thn 60rwhp
