I don't think all the Bosch models have that feature. I know my Samsung dishwasher had that feature but it was in the door and didn't really invade any of the actual interior space of the dishwasher. When I got my Bosch, the instructions indicated that there is no heated drying element/motor/fan and the unit is designed to hold the heat from the wash/rinse cycles in the stainless steel walls of the tub. I do remember seeing some models with smaller racks, but the model I have definitely doesn't have those. When we bought it, the salesman told me to wash the dishes at night and not open the dishwasher until morning and then everything should be dry and I've found that to be true. The only problems I have with things not getting completely dry is when -- like a PP mentioned -- there is an indentation on the bottom of the cup, mug, or dish and water pools there. If I have a few pots and pans in the dishwasher things tend to dry *really* well because they hold the heat longer than my every day dishes, glasses, and cups. The only time I have a problem is when I wash a lot of plastic items in one load -- and that makes sense as plastic inherently doesn't dry well and it certainly doesn't hold the heat and help to prolong the "drying" cycle.
