Here are a few examples off the top of my head. Of course, the aforementioned Volt:



Also its sibling, the now-departed Malibu:



(Sorry, some of these pictures I was more interested in the wheel strakes than the air dam).

The Audi A4 uses a sectioned air dam and undertray:



So does the TT:



The Honda Clarity has this curious center air dam despite an almost completely-covered underside:



The Kia Telluride uses a full air dam, separate wheel strakes, and engine undertray:



And of course, the Mustang Ecoboost has this interesting air dam + undertray combination (this one isn't my picture):



I can't speak to why these designs are out there. Your guess is as good as mine, which is pretty worthless without any data.
