The motor mounts are shot on my 400e. I do feel the vibration of the engine but it's really not THAT bad - actually, kind of reminds me of a Porsche 928! But my mechanic says I'll notice a BIG improvement if I put in new motor mounts. I would like to do what I can to improve NHV in my car - anyone done this lately?

Also, I notice that there are cooling ducts directed at the motor mounts. Why? Shouldn't they go to the front breaks instead?

Can someone please explain the reason for the floor hinged accelerator pedal? Sure it looks cool but ergonomically it dosen't feel nearly as comfortalbe as a non floor hinged pedal. Please give me some "German Engineer(ing)" type answer at least!

Isolating the vibration from the engine is not only good for "the feel" but also benefits the rest of the drivetrain and all the other MB bits.

Cooling ducts would make sense since the hydraulic units are pretty much trapped under that engine. Additional cooling for the brakes, while practical if you race or live at the top of Pike's Peak, is sufficiently handled by the existing airflow and wheel ventilation.

As for the gas pedal . . . I leave that to white coats in Stuttgart. You'll be happy to know that one of the safety features MB designed into the pedals, is that in a front crash, they will move upward, out of the way of your legs and knees.
