I'm considering purchase of a V70 R to replace my STi. I've seen some comments about the Four C being not-so-robust. My home is located about 2 miles away from the nearest paved road, so the car sees plenty of gravel duty, and the roadbase can become rutted after heavy rains. I don't think grip would be a problem, but I'm concerned about the long-term durability of the Four C system with exposure to these roads. The STi has held up fine, but it's more of a conventional system than that on the R.<p>Any experience or advice on the subject is appreciated...<p>Cheers! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/embeer.gif" BORDER="0">

Re: Four C durability on gravel/rough roads (needsdecaf)

I would STAY AWAY from ANY 4C system if I had to drive on gravel roads. My car rides great on great roads. And terrible on terrible roads! I would find gravel in the latter analogy! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/sly.gif" BORDER="0">

Look up "sidehopp" with the search function. Some (not all) have the side hop so bad that even the smallest road imperfections will make you second guess who actuually has controll of the car. You OR the road! You will have NO COMFORT regardless of the setting you choose on a wash boarded road! Sad but true <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/sly.gif" BORDER="0">

XC90 V8. No turbo cool down to worry about, and enough ground clearance for your needs. Get the sport one if you like to push it a little.

Took my R hiking last year. A mistake. Bottomed out once (stock suspension). Steering wheel rattles over washboard. Very dissapointing. I realize it's no Subaru WRX, but even an Audi will do better. Just not made for offroad use even though it's AWD. Stay away!<br>

Re: Four C durability on gravel/rough roads (whoosh)

The main thing I would be concerned about is shaking some of the sensors or control modules loose. Some people on this board have found them to be loose already (after driving on paved roads). After they tightened them back up they have found their ride quality to be significantly improved. I can't imagine what flying up and down a washboared gravel road would do. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/eek.gif" BORDER="0">

What are you talking there? Have you driven an R on gravel and forest roads?<p>Before making assumptions go take a drive.

Re: (jazee)

If you think Volvo has stiff suspension go drive an STi. You'll see what rattle really is.<p>

Just stick with 17" wheels and 235/45s. I have driven on some gravel roads that it would be pointless driving anything but a "beater" car on a daily basis.

Re: Four C durability on gravel/rough roads (whoosh)

Now here is not how I think is driving an R on gravel and forest roads but how it IS. Here in Pacific NW we have plenty of space and opportunities to test that.<p>I've done it often and unfortunately I do not have the time to switch to winter tires before going so I've done it each time on my PS2's. I do not recommend this to anyone that wants to get some miles from the tires. The wear is very high.<p>Going on Olympic National Park alone in the car on very windy and narrow roads with trees almost on the road, dry dirt surface with loose gravel in the corners - 3 miles, altitude 200 ft. Speed up to 40 MPH w/o risking it. Adrenaline - huge, fun - huge. Haldex is a wonderful invention. 1/3 through the corned mash the gas and the car end rotates under power to point you to the curve exit - excellent. You can clearly feel power transfer to the rear wheels and the transfer was fast. Amazing stability and road holding for such tight turns and summer tires. With gravel tires I could have gone faster. Suspension on advanced on the tight turns part of the road, and sport on the rest.<p>Mt Rainier National Park Mowich Lake road with family - 16 miles one way. Dry surface, lots of lose dirt and gravel, 4000 ft altitude, huge clouds of dust - visibility 30 ft in places, very popular road for Off Road guys going to the popular ORV parks along the way. Wide road with large curves so with a proper equipped car and no family you can do 60 or more (speed limit is much lower though).<p>When going on the very undulated surface (like a test piste at the factory) there is a lot of rattles. It was not worst than I experience in other cars with a lot softer suspension. You have to get the speed right so the car does not resonate with the rooting surface. Sometimes the right speed was 30 some times it was 20 and some times 40. Suspension on comfort (did I mention family).<p>Mirror Lake Trail Snoqualmie Pass - road surface mostly gravel with dirt in places, very little lose gravel. The challenge are the potholes. On comfort car was very pleasant. The only thing that I had to take care was to pay attention at potholes and to carefully chart my way so I do not bottom out on stones.<p>In conclusion: V70 R with 17" is a very capable gravel road machine. If not for the low clearance. Actually let me correct myself here: if you do not care about the front bodywork and you have gravel tires, it is an excellent gravel road machine.<p>It is not an off road machine so going over holes, or tight approaches/departures is not an option.<p>You will have to see for yourself how bad is your road in terms of holes. The only worry that you should have are the holes.<p>I drive a 04 V70 with 17 wheels and stock suspension, no suspension software upgrades. I seldom have the hop on big holes in the highway (for the local guys: the SR520 West at the bridge over Northup Way before the exit for 405 going on the left lane) but never had it on forest roads. I always drive around holes no matter how small and what car I'm driving so my experience may not match yours. I learned to drive in a country with much worst roads so dribbling the holes was a necesity.<p>Please enjoy responsible <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">
