As I understand it, there is a new DOT or governement regulation that has to do with pedestrian safety which mandates that all new 2013 or 2014 vehicles and up have some sort of protrusion at the lower facia. Whether its a bumper or something like we see above as well as on the C7. As a result, I would expect most cars without bumpers at the base of the front facia to have something similar. There are only so many ways to skin the cat and as such, I would expect many of the new cars will have similar "fang" looking protrusions down low.
That or GM just copied Honda because the Civic is so cool!

The document below gets into some of the testing info regarding Pedestrian Injury Mitigation which is what is driving these new protrusions at the base of the front facia.
If you look at the link below, Lee 6 which should be page 6 has a diagram and in particular item C in figure 6 is where that comes into play.

This document gets into some of the science behind it leading up to the latest mandates. It shows some of the progression up until 2010. Shows crash dummy testing as well.

Nope.. I don't think that is the case. A quick search of Honda Pedestrian Injury Mitigation Front bumper will show you why they did that. I am sure there may be some aero value to it as well but that is not the driving factor.

I figured you might have been sarcastic but wasn't completely sure. Besides, some people would probably take you seriously. Most of us know Hondas don't go over 65MPH unless they are going downhill!
I was already trying to find the info on that whole pedestrian safety crap for my own sanity as well as this thread so I figured I would post it just to give people some good reading.

The specific shape can also be used to direct the pedestrian towards a spot on the hood which will inflict the least amount of damage (due to flex of the hood) to the cranium.
There is of course an aero benefit of the specific shapes as well in that they will offset drag induced lift components from the rear of the car by acting as dive planes at the lowest frontal area of the fascia.

It doesn't require the cow catcher. Various interpretations of the requirements will arrive at the same conclusions. The first benefit of lower fascia reinforcement is that it will cause the leg to flex below the knee and direct the pedestrian toward the car rather than damaging (seriously understated) the knee.

There are various ways to include a lower fascia reinforcement that will meet the requirements.
Worth noting also that these requirements come out of Eu NCAP phase 2 which is feeding the DOT. Cars not slated for sale in Europe will have a lot less to consider.
