I love the sound of the engine when floored.
Honda's have a nice F1 sound .. and then the MB - which sounds more like a plane taking off (thats before the shift to the next gear up). Bimmers flooring isn't very inspiring as its a deep throttle, but erm ... can do-lah.
Drive the MB like you stole it. That way, you derive 100% maximum satisfaction. Guaranteed.
On the gear ratio to rev changes - its all preset unless you request the MB service centre to change the settings. Perhaps MBDoc would advise you further.
Drive on "S", and you'd be flying with a
on your face.
However, if your model comes with a Slushomatic or steptronic, you'd have more pleasures than you can ever ask for.
