My new 2016 C450 AMG
I don't know if its programmed into the engine's electronics, or something with the transmission, but it can be frustrating, and sometimes surprising and dangerous. I have come to expect it and live with it. There is one highway entrance ramp that I take every day, and simply due to the geometry of the curve and the speed I'm at going in, this lag happens every time without fail, no matter what mode the transmission is in.
That being said, I still love my car because it drives like new and looks like a beast, and will only give it up now because of the kms.
