I am thinking of putting a yakima or thule roof rack on my new s40. I have a sunroof, i was wondering <br>1)how much noise does it produce with the sunroof open, is it tolerable?<br>2)does the roof rack deflector help<br>3)How much does the roof rack affect milage with or without the deflector?<br>Thanks!

I don't have any great quantifiable or objective data for you, but I have heard that the ski racks are good for a ~5mpg drop in mileage. <p>Given that you're in CO I assume you're talking about this for skiing... maybe you could remove the rack when you're not skiing? ...or what about storing the skis in the car? <p>Just some thoughts. I see folks driving around all the time with roof racks and I always sort of shake my head in disbelief after hearing of the mileage drop... <br>-Chris

yea, thats what im afraid of. I commute 100 miles a day to work. and i actually want it for bikes. Now, im not talking about gas mpg with bikes on, i know that will suck, im talking about empty. 5 mpg is to much to swallow. And i dont want it to roar the entire time i have the sunroof down. Its hard to have your cake and eat it too....<br>Believe it or not, i never ski here. Strange i know, i live for summer. Strange given my 9000' in elevation that i live at.

Re: Roof rack for a s40 (DazedandConfused)

I have a 2005 2.4i S40 with the roof rack rails, 2 fork mounted bike rails and 2 front wheel holders. It just depends on your tolerance level. I carry my bikes almost everywhere and love the convenience of just being able to load them and go. If I'm taking long road trips like the one I just took to Maryland (1200 mile drive for me from TN) I take the rack off. The MPG decrease is pretty substantial on long trips. I drive about 20 miles to work every day, and having it on around town and to and from work the MPG loss is not that noticable. <br>With the rack on the open sunroof makes the interior of cabin quite loud. When I have the windows down and sunroof open on a sunny day with the rack on I have to turn my music up about half the max level of the stereo to clearly hear it while driving on the highways, around town is not as bad. I don't have the wind deflector for the S40 roofrack only because I never looked into getting one because I didn't know they made them for the newer models and newer model racks.<br>The rack is secured very well. Volvo did a good job of designing it to conform to the roof of the vehicle. The design that Thule came up with for the bike rails is amazing sturdy (the bike rails are made by Thule and have a volvo sticker slapped on them). There is no rattling without the bikes on the rack and there is VERY minimal rattling with the bikes on the rack. <br>So it's your call. If you do ALOT of biking like I do then the rack is worth it. You can remove it very easily (only takes one person but is easier with two) and put it back on easily. Around town the MPG loss is minimal, on long road trips if you aren't going somewhere to ride or aren't going to ride while your gone then you should just remove it because I've noticed a HUGE difference when traveling long distances. I love it and couldn't live without that convenience on my S40. Others don't have a need for it and don't understand.<p>adam

Thats perfect. Just the info i wanted to hear. I think i will just take the truck with the bike rack when i want to ride, and keep my fuel efficient s40 the way it is. If i drove in town more it would be one thing, my commute is mountain highway with very few stops. Im impressed so far, my s40 average fuel consumption is 27mpg. Not bad considering i climb a 4000 foot canyon everyday. I dont think i will mess up a good thing. Thank you for all the responces.<br>

Re: (DazedandConfused)

Sounds like you've already made the right decision, but I wanted to echo the earlier comments about decreased gas mileage. I only used my ski rack once this past winter, but I left it on for a couple weeks and noticed a substantial drop in MPG - I lost about 4+ MPG while commuting on the freeway. I was pretty surprised, and took it off right away. <p>I think having a wind deflector would improve this substantially - probably you'd get back 50% off the lost MPG. A deflector also cuts down on the whistling/noise from the rack quite a bit. But I'm still not sure that it'd be worth leaving on all the time if you're commuting every day. <p>I'll probably only wind up using my rack a few times a year, not really as much as I had planned. But it is pretty damn useful if I go skiing with 4 people in the car. If you have a truck, I'd definitely just use that when you need to haul bikes!<br>

I thought the Volvo used thule rack system if that the cast, here is the faring for thule.<p><A HREF="http://www.thuleracks.com/thule/product.asp?dept_id=16&sku=871" TARGET="_blank">http://www.thuleracks.com/thul...u=871</A>

Re: (DazedandConfused)

I know we're talking bike racks here, but I only see a 2mpg decrease when I have the load bars and EuroWeekender box on top of my S40.

Only recently got THULE bars and a fork mount bike carrier for mine.<p>Found the noise level to be tolerable up to 70mph. Worse with the bike carrier on but still ok, <p>I had it on all last week and I do twice week 200+ mile commute other days about 100 per day not really noticed impact on the fuel. But mine is diesel, will be much worse when the bike is on though. <p>Much better than the rear mounted carrier I used last year that I thought was always about to fall off!!! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/eek.gif" BORDER="0"> <p>Only taken it off this week as I have some clients and big boss managers to hike about........

What about the hitch mounted bike rack. Those work well and you wouldn't have to worry about the wind noise or the MPG lose.

i know the rack is the same as thule, but I believe the load bars are different. rack being what holds the item (i.e. bike rack holds bike, ski rack holds skis, etc.), load bars being what attaches the rack to the car. so, i'm not sure if the thule fairing would work with the volvo load bars. can anyone confirm or deny this?

I have a trunk bike rack from Yakima which has worked very good. I don't think there is any significant mpg loss. At first I didn't think it would fit or look good. But it's actually very easy to install (i.e. 5 min) and it doesn't look bad. If you don't have the bike on it, you can still open the trunk. It's cheaper than roof racks, too.
