QDII/ELSD on Dry Roads
I've seen a lot of discussion about QTII vs QDII in off-road conditions. My question is whether or not the Rear ELSD from QDII will improve handling/cornering/traction or other driving capabilities on dry roads or other normal conditions such as rain or light snow. Will it bias the outside rear wheel during a turn (i.e. Acura's SH-AWD or Audi's Quattro) if it starts to sense a hint of slippage? In other words, would I notice the difference between QTII and QDII in normal driving conditions?

I'm closing in on finally pulling the trigger on an Overland and am weighing the factors in whether or not it's worth it to get the ORA II or Summit packages. There are pros and cons to each of these packages, but the QDII is a strong consideration. I don't really plan to go off-roading, but naturally would like the most capable vehicle for increased security, confidence, and control on-road. I just don't want to shell out extra for QDII (and potentially wait to special order one with ORA II) if I'm simply not going to notice a difference.

Thanks for any thoughts/advice you may have.

Re: QDII/ELSD on Dry Roads
Its a 5000 lb SUV, not a performance car. I doubt you would want to take a turn fast enough on dry roads to come close to noticing the difference the ELSD makes. If you punch it from a stop while making a sharp turn, there will be more power delivered to the road (more acceleration), more control, and less wheel spin. The ELSD will rob less power than the standard traction control.

On slippery roads, the WK2 will appear to stick to the roads without wheel spin.

The WK2 does come standard with stability and sway control, which is implemented by the brake controller. Not sure if enough information is available to determine if or how the controller also uses the transfer case and/or rear end clutches.

In everyday driving you are not going to notice ELSD, in my opinion, unless you are looking for the subtle hints. The worse the road conditions the more you may notice. Tires and driver skill makes more of a difference I think.

My 2011 is equipped with ELSD. You may want to test drive a WK2 so equipped and decide for yourself as sometimes the but dyno can be subjective :)

Re: QDII/ELSD on Dry Roads
There is a higher likelyhood to get a "Service 4 Wheel Drive." warning if you get the ELSD. That's something to think about maybe too.
