Follow the link to the article that appeared in my hometown newspaper today (Roanoke, VA). Apparently, there is a new Acura sedan on the way and the commercial was shot on the Blue Ridge Parkway.

The top-of-the-line RL sedan is expected to be replaced with a new rear-drive version, using the same V8 as in the new NSX.

Maybe that's what it was?

 

That's probably just the TL or reskined TL.
Hey, maybe it's TL Type S!!
I'd be more excited about a TL Type S than RL. (if I want to spend the money for RL, I might as well get LS430)
The RL isn't close enough to release for a commercial, is it?
