Imagination?
 

Is it my imagination or do the brakes damper themselves slightly when you take your foot off of the accelator? It feels as though you have downshifted a gear ....seems like I read that somewhere but not sure where?

We just purchased a 2013 E70, and I can't say that I have noticed this, but do remember reading in the brochure about a couple of features that may be contributing to what you feel..

From the Brochure "Brake Stand-by pretenses the brake calipers when you suddenly remove your foot from the accelerator pedal. Brake Drying lightly dries the brakes when rain sensors detect moisture"
