When is it clear to drive?
Hope each and every one of you guys is enjoying their C63

Just a simple question here. I'm quite concerned when are we clear to drive? (referring to the C63s w205). I had an audi before the AMG, and the only thing I used to do when warming up the engine, is start the engine and wait in the car for 10 minutes or so ,to get the engine temp upto 90 degrees.
After getting the C, I noticed and was assured by my salesman that the vehicle will start to consume more fuel when idle. in addition, in the user manual its stated that "don't allow the vehicle to warm up simply by idling.
How do you guys do it? put in mind, I leave the car for around 16 hours so when I start it in the morning, the engine is damn cold! Shall I do what I have been doing with my Audi for the past 5 years? or just drive it after the rpm drops below 1000, but with a low speed?
inputs are always appreciated !
My car sits for hours to days at a time. I start it up, pull out of the garage and idle for about 2 minutes. Then just drive "normally" (as if I drove a boring car).
Don't go doing 0-100 sprints when she's cold. But at the same time don't be afraid to move with traffic.
I don't even switch to my Individual mode until the temp meters tell me both engine and tranny are out of cold range (about 10 mins of normal driving) Then all is well and I drive like I own an AMG.

Temperature 0 F or below, warm up for 1-2 mins.
After those warm up time or at any temperature above 32 F, just put the car in gear right away and drive like a granny until the engine temperature is at optimal.
When you turn the car on, the idle is a few hundred RPM's higher for about 30 seconds. I wait until it goes to normal idle then start driving (about 30 seconds... when the RPMs drop). Then I wait until the temperatures turn white to thrash it about (5 minutes maybe?)

Checked the temp display on the way home this evening.
It switches from blue (cold fluids) to white (operating temperature) at ~170F/75C for the engine oil and ~152F/65C for the transmission.

I imagine I'll drive the C63s in exactly the same way.
My tranny doesn't like to go in the morning when it's too cold. Rpm's shoot up to around 2k and I'm barely creaping along. Goes away after the first few feet of pulling out of my driveway though. I'm at approx 1100 miles
So, I've started it today morning and let it for a minute maybe then I pulled back from the garage and drove it with a max speed of 80 kmph until the temps hit normal.

Just drive it normally until it's warm, then start having fun

My C63s left Germany on Boxing Day and passed through the Canary Islands en-route to East London (South Africa) followed by Melbourne (Australia) yesterday. I should have it in a touch over one month. Can't wait

I haven't noticed that with the A45. When it's cold, it'll run loudly and at a higher RPM than usual for a minute or so. I think this is the choke doing its thing. Other than that, it doesn't bounce around. My VW R36 (3.6L VR6) will fluctuate RPM slightly during cold idle, but not much. Maybe a hundred RPM here, a hundred RPM there. It's never cut power, but then again it doesn't have a valved exhaust like the A45.
