Here is a simple set of examples from Haldex. I am not sure if all of these apply to the Haldex AWD system as implemented in the S60, but it is rather interesting reading...<BR> <A HREF="http://www.haldex-traction.com/technical_information/six_dimensions/control_samples.htm" TARGET=_blank>http://www.haldex-traction.com/technical_information/six_dimensions/control_samples.htm</A> <P>Also, here are some graphs:<BR> <A HREF="http://www.haldex-traction.com/technical_information/performance_info/performance_graphs.htm" TARGET=_blank>http://www.haldex-traction.com/technical_information/performance_info/performance_graphs.htm</A> <P>If anyone in the know would post discrepancies about this information and it's applicability to the S60 AWD that would be greatly appreciated.<BR>

Thanks for the great information. I am pretty sure all of those control samples applies to the S60/V70/XC90. One very neat features of Haldex AWD is the 50/50 torque distribution during full-throttle starts. <IMG SRC="http://www.swedespeed.com/ubb/biggrin.gif"><P> <BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>In a full-throttle start, the Haldex LSC distribute all available torque between the axles for best performance – automatically.<HR></BLOCKQUOTE><P>-Drew<p>[This message has been edited by InDy (edited 02-27-2002).]

The XC90 will use the Haldex system, and the V70 and V70XC will be switched over to it (currently a viscous coupling system). Volvo uses the same system as Audi with the TT, but theirs is phase II, meaning it has a different casing and a couple other differences. I believe your samples here are accurate.

George, I'm looking at getting a V70 AWD next year and I just received my S60 AWD this evening. Do you know when Volvo will switch over to the Haldex on the V70?<P>Pat

I had to probe an even then I could not get a firm answer. But, yes, any DSTC XC or V70AWD (supposedly) will come with the new AWD. Actually, rumor has it that all V70s (AWDs and XCs) being produced starting with production week 04, Haldex will be it.<P>Yannis<P><P>

That makes sense. I seem to remember reading somewhere that engineers couldn't get DSTC to work with the VC setup because it was mechanical. The controlling impulses from the system would theoretically not be able to control the viscous coupling which is solely activated through slippage. Makes sense that DSTC cars would be Haldex.<P>I'll try to confirm this though.

Well,<P>Seems that Volvo doesn't know what products they are selling at the moment.<BR>After an initial confirmation from Volvo Marketing about Haldex in the V70 they came back on that statement this morning after calling their factory in Sweden.<BR>The Haldex production start is sheduled for week 35 this year! Can you believe that?<BR>My brother drove an older model V70 AWD which was tuned to approx. 250 HP and I know from own experience that the old visco system isn't the right system for fast driving, to slow.<P><BR>
