The splitter
This little bend below the bumper to be the key to NASCAR's Car of the Future. At least that's the take of this story.
I'm not sure why it's being called a splitter. Think of it as a recessed nose, or rather a recess underneath the bumper. The Charlotte paper had the best picture. Since it's not online, this picture essay will have to do.
Here's the current version - specifically, the No. 8 Budweiser machine. You remember this car - high hopes, poor season, didn't make the chase? Notice the nose of the car:

See how it goes more or less in a straight line from the edge of the hood to the track?
Now take a look at this Truck Series bumper:

Sorry for the poor quality pic, but AP didn't give me much to work with. Anyway ... see how the truck nose kicks back in toward the nose?
NASCAR's COF has the same feature. NASCAR.com has a picture of Jeff Burton's ride, the one that took a spin through the front stretch Monday.
The Scotsman has side views.
Diecast Dude, meanwhile, likes the idea of a COF.
Update #1 (Tuesday night): The super secret site for those media type has a good picture of a splitter. Here's Kyle Petty's car:

See how the nose juts forward, then is pulled back?
See how there's actually a bumper on the car?
