Until I don't see some wheel dyno numbers I won't comment on the power loss.
Semi automatics don't really like torque, the one torque resistent semi I know is the special Ricardo dual custom made for the Veyron.
Ofcourse it probably costs as much as a C63 or M3.

If Getrag can do it I'm sure Mercedes can unless they already plan to outsource them.

True.
M3 sedan vs. C63 vs IS-F vs RS4 is the only valid apple-to-apple comparison. And with the same tire types ( eg. semi-R vs semi-R) & same package (standard vs standard, sport / driver vs sport / driver). All other combinations are a pure manipulation (eg. coupe vs sedan, sport/drive pack vs standard pack, standard tires vs semi-R tires).


Btw, M3 sedan weights only 25kg more than the M3 coupe (1605kg vs. 1580kg - both figures by DIN standard = weight w/o driver & cargo).

It's quite a leap to conclude that one car is more fun to drive than the other based only on steering feedback. Feedback is an important aspect, but it's only one element of steering. And steering is but one element of vehicle dynamics.

More from Chris Harris for those who missed it:
"One wonders how much better the steering on an M3 would be with a standard 3-series wheel fitted; a good deal improved, I suspect.
If the AMG responds well to some vigor, then it’s the M3 that still has the greater appetite for such treatment. Extend that 4.0-liter V8 beyond 6000rpm and a different car emerges – one that feels both faster and more athletic than the C63. Tip it into faster turns and the benefit of having less mass over the front - ONLY REGISTERED AND ACTIVATED USERS CAN SEE ALL LINKS - CLICK HERE TO REGISTER is immediately obvious, and the extra agility afforded by being 320 lbs lighter overall is undeniable. [C&D found it closer to a 460-lb difference]
the current M3 coupe tests just how much drivers want to be rewarded when the time comes to have fun – when the opportunity arrives to stretch that sensational engine beyond 8000rpm, to kill the DSC and feel that back axle arc wide from a second-gear turn. Because, for those moments, it is the only car that will satisfy on that level.
I’ll give it to the M3, on the grounds that it can still worm its way into your bloodstream when the time comes, while being only slightly inferior to the C63 on the daily grind."

of course I will drive the new C63 and hopefully you drive the M3 too. You can be sure of that I will drive the IS-F if I get the chance too. Great news, IS-f will be for sale in Sweden

yes, we know AMg is developing such gearbox but the gearbox for BMw is coming soon. also, manual is still not a seqventiell gearbox.

Maybe Autozeitung should test the C63 again, because when they tested the M3 for the first time (with R-tires etc.) it did a time of 1:40.1 (1,1 sec. slower than this second time and just 0.2 secs faster than the AMG).

different time different day, different conditions, different driver. Maybe they should retest the M3 again. Heck, create a big party and retest every single car the tested during the years.

They have already re-tested the M3. The C63 deserves a second chance too, maybe then it could beat the M3 in the only area where the M3 is (slightly) better.

I doubt it. C63 will have a big chance on big tracks but on smaller it will be more difficult. M3 weigh less and is more agiler. M3 has the advantage in bends while C63 has the advantage in straights.
Im looking forward for Sportauto supertest on the C63.

Yes, the M3 is a little bit faster in the corners while the C63 is quite faster in the straights (well, except maybe in m5 board events )
