Does anyone know what version of the Haldex AWD is in the 2009 S40 T5 AWD? Is it the XWD system? <A HREF="http://www.haldex-xwd.com/" TARGET="_blank">http://www.haldex-xwd.com/</A>

It's a simple system that modulates the brakes on the slipping wheel to transfer torque to the opposing wheel with traction. DSTC (Dynamic Traction Control) is the next advance that incorporates a yaw sensor and steering angle sensor to help maintain the driver's intended path in the face of a sudden traction loss (slide, skid, etc.).<p>I have AWD and DSTC and the two systems perform pretty damn well on wet roads and during hard cornering (wet or dry). <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

SH-AWD can shift power to the left and right only in the rear. <p>Here's my rant. There are other cars that can send power to the left and right as needed. However, SH-AWD can also transfer engine braking force front and rear and side to side (rear) as needed for stability. Here's what nobody else has- the planetary gear setup on the rear to spin the outside wheel 5% faster in a turn. Why has Acura/Honda not promoted this or its lineage? Starting w/ 4 wheel steering on the Prelude in 1988, and then the Prelude SH in 1997(?). The Prelude SH used this type of planetary gear setup to reduce the inside wheel spinning in turns and was the best handling FWD car made. They just put that "differential" in the rear of the RL/RDX/MDX and gave the 4WS effect. Drive your RDX fast around turns, and you will feel the rear end rotating around which reduces the turning load on the front tires. Absolutely stellar, yet hardly anybody seems to understand that this is the key to the SH part of the AWD.

Re: (PPower)

Back on topic... XWD is the system available on the Saab 9-3 and on the TurboX. I see that Hyundai has a contract to use Haldex XWD on some vehicle. Interesting.
