"electronically controlled shutters in the lower grille close at higher speeds to push more air over the vehicle."

Simple but clever!

that sounds familiar... does another GM vehicle have this too? like the volt maybe?

The same feature is used in the Cruze.

There was another car that had the main grille which closed at high speeds a few years back, maybe Mercedes?

But there's really nothing new. In the '30s Packard used a thermostatically controlled grille to regulate engine temperature. Obviously not for aerodynamics, but same idea.

2012 CTS is going to get this... so I'm told

I also like the idea of eAssist. A mild hybrid that easily pays for itself in fuel savings.

I agree, Jesda. Mi-brids are fantastic.
