My 211 had this feature, and it was adjustable. Worked well.

My '11 212 does not seem to have it. Did MB do away with it? If it does have it I can't seem to find any trace of it....

Just going by ear, I'm pretty sure my '10 has it, it definitely appears to increase the volume especially initially pulling away from a light from a stop. I can really only notice it when the volume is fairly low though, nothing really at moderate to loud volumes.

Never could find an adjustment for it though...
