Yes, the RioCar is the empeg in a different name.
Empeg are a wholly owned subsiduary of Rio (read - own 100%). So the product (previously empeg) is now RioCar.
The faq is talking about the MK1, and that page is woefully out of date.
Here's a link the the Rio webpage, which is uptodate.

Hope this helps.
BTW - take a look at the FAQ section of the board - there's a whole bunch of really useful information on there, especially about things to know about installs, etc.
Don't let us put you off - everyone here *loves* their empeg (to some degree at least!).
