UPDATE: The 2014 Chevrolet SS has been confirmed as the VF Holden Commodore. Click here for all the details.

Just days after Chevrolet was found to have trademarked the "SS" nameplate, OnStar's vehicle compatibility guide has stepped up to list the "SS Performance" on its 2014 roll sheet. Seems like something's cooking here, and it smells like Caprice.

Or is it Commodore? Holden, GM's Aussie division, is known to be working on a facelifted version of the Commodore. The same car, in last-gen form, was sold here in the U.S. as the Pontiac G8, and is currently being sold as the Chevy Caprice--as a police cruiser. Could the upcoming version of the Commo/G8/Caprice be Chevy's SS Performance? Maybe.

The information, dug up by tipster Christopher Price, stops at the name. There's no indication of what the car may be, so we're left with our best guesses and linking together previous rumors. But that's half the fun, right?

We'll keep you posted as we learn more.
