My aunt has an '05 cross country wagon, and it has essentially the same engine as my S40 T5, but it's SO much quieter at idle!I was amazed at how quiet the engine is from the outside. At idle my car has an almost jet engine sound coming from the front,plus other sounds that are absent in the cross country. What's the difference? Arent the engine pretty much the same? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0">

Nope. The displacement is the same but the block design is different...and perhaps the turbo as well.

You probably listened to the S40 when it was trying to cool itself down or starting up. I hear that sometimes when I'm outside the car. Try listenting to your car after it has reached operating temperature.

Its not a big deal at all, but for relatively the same engine they sound so different. it just surprised me how much quieter it was. I guess the S40 has different pumps, fans, etc. that are louder than the ones used in other Volvos <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/cool.gif" BORDER="0"> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">
