As it is winter and many around the country are dealing with ice, we have put together a tech feature on DSTC and how it works. It will go live Jan 23 on the front page.

A lot of people shy away from such a great feature because of cost. Unless it is explained to them, they will not be able to see the value of such system. Please let me know!<P>Yannis<P><P>

Sure Yannis. One thing to note. We did a piece on ESP several months ago on our VW sister site.<P>I was recently in Calgary with VCNA driving DSTC cars in snow and ice conditions and got a great feel for it. While there I asked the difference between DSTC and ESP used by VW and Audi, and I was told that the only real differences are algorithms used.<P>For this reason, I have reprinted, with some changes, an article from our VW sister site, changed to suit Volvo.<P>I will be doing a secondary article on the S60 AWD in winter situations with an emphasis Haldex and DSTC combined. That'll be in a couple of weeks though.<P>However, having seen how handy it can be first hand, I decided to fast track this particular article.

It should be a very interesting article. From what I have heard the Volvo DSTC system is the same system as Stablili-Trak 2.0, used by Cadillac. Meaning that they use hardware made by the same company and their algorithms are pretty much the same.<P>I know for sure that the new Night-Vision system used in the XC90 is the same system used by Cadillac, developed by Raytheon Systems.<P>-Drew

I just wanted to check so I would not break any copywrite laws...<P>I discovered how well DSTC works, by accident, two years ago. I was driving my, then, demo which was a 1999 Polar Arctic Metallic S80 T6. It was raining fairly heavily and I was coming to an itersection when the light all of a sudden changed from Green to Yellow. I was only 30ft. or so from the turn (about 90-degree turn) so I pushed the gas pedal a bit more in order to "beat" the light...I made it but did not relaize that at the bottom of the intersection there was a fairly deep puddle of accumulated rainwater. My speed was about 35mph (as I was turning). Of course, I lost contact with the pavement and I felt the car's tail want to give out on me and induce a 360. All of a sudden and while I pointed the nose of the car where I was supposed to go, I saw the DSTC light flash, heard the ABS system work and a "magic, giant hand" STRAIGHTENED the T6 and here I was! I was so amazed that it took me a few seconds to realize that what prevented me from skidding laterally and facing the direction I was coming from was..DSTC! Next pportunity I had, I tried to make the car spin and it absolutely refised to do so! A few weeks later I had the chance to try it on an empty parking lot with about 3" of snow on the ground. Very neat system!<P><BR>Yannis<BR><P>

We had a similar experience up in calgary. Volvo provided us with some test courses, one of which had a very sheer ice area. I took an S60 AWD with DSTC onto the patch with and without DSTC and basically, from a standing start, floored it and turned the wheel back and forth hard. <P>I was surprised at the difference. Oversteer is surprisingly taken into control, though you also loose the whole fishtail effect you might look for if you were say a hooligan. This I guess is why there is an off button. <IMG SRC="http://www.swedespeed.com/ubb/wink.gif"><BR>

That is a nice picture of the S60 AWD in the snow! <IMG SRC="http://www.swedespeed.com/ubb/smile.gif"><P>-Drew

Nice article. I always kinda wondered how this works ever since I saw ESP involved in that whole MB A-class thing. <P>I don't know why Volvo doesn't make this standard. They should.
