Yeap...from dead stop, no RS yet but very fast starts

My 2015 is instantaneous from the full stop, but does have a VERY annoying hesitation when trying to accelerate from rolling speed.
I replicated it at will and noticed that the car remained in high gear (4) and didn't downshift while it was barely rolling...
Measured ~1.5 - 2 sec lag between me stepping on accelerator and transmission downshifting.
Tomorrow will try "manual" and see if keeping the beast in right gear helps...

weird how my 14 is opposite. Has hesitation from a complete stop before it starts moving, from a roll no hesitation with instant down shifts

I think people here have different opinions about what the hesitation is and what the lag is depending on what other cars you've driven.

in my case compared to 2016 911 4s, 2013 458 Speciale, and a test drive in a 2016GTS both in the US and DE.

agreed

My GT-R had slight throttle lag too when you stomped it at a light or even on launch control. It was much less significant than this car, but still there. I think this is completely normal for cars with a dual clutch transmission. My E55 had none of this at all... because it had a good ol' torque converter.

when im in my 2008 g35x ... my foot memory is so used to the e63 that I always snap into acceleration -- my foot forgot how instant the torque converter makes initial acceleration ... after the first 15 feet of acceleration the e63 is way more fun

bottom line I've determined is that the 2016 models have the same lag, but there is a possibility the 2016 models have smoother shifting

in my thread here, some 2016 owners may have commented on the lag:

wow, very nice!

what I don't understand is that the 12+ c63 uses the same MCT transmission as the e63, with no torque converter and I remember stomping it off the line had absolutely no lag at all before it got going. It felt telepathic with the throttle.

I think its the software in the TCU making this dumb lag, not transmission. If it's transmission I wonder why the w204 12+ c63s don't have the same problem.

Amg63-

interesting, what do you mean by "smoother shifting" ? Do you mean to say it has reduced lag from a stop or that once it's up and already in motion, the transmission feels smoother shifting?

efiftyfizzle

if that's the case then it's the software in the transmission probably preventing the car from giving it too much power at once to prevent it from damaging any components. These cars make a lot more torque and power than the first gen c63

Amg63-

yup that's exactly the point I was making. People think it's the actual MCT hardware causing this lag, but really it's all in the software, nothing to do with the hardware itself causing it.

No no wonder a c63 amg with far less torque has no lag at all before it gets its *** moving from a stoplight.

Who wants to assume the lease for this beast? PM me if interested!
