I think "advanced" airbags differ from "dual stage". The way I understand it, "advanced" airbags include a passenger seat occupant classification sensor to measure weight and sometimes occupant position relative to the airbag. "Dual stage" airbags have two deployment speeds, with the speed selected based on sensor feedback from seat belt use and crash severity. Most new cars today have both of these features on the airbags.
The US Volvo web page <A HREF="http://www.volvocars.us" TARGET="_blank">http://www.volvocars.us</A> describes the air bags. Look under specifications for the Volvo model you are comparing. The main SRS bags in the S60 are described as "dual threshold."

I found this strange that Volvo would make such a simple mistake on their flagship luxury car on something they are supposed to be the kings of? Anyways, I wouldn't be worried about the Volvo standing upto a CRV.
