Interested to see how it behaves cornering. Also from a full stop and then a 90* right hand turn requiring accelerating.
Yeah..from what I have seen, cornering while pressing hard will indeed throw the rear wheels in full traction....while they should rotate slower than front wheels....very bad idea....not surprising that if the rear wheels stick on the asphalt, then the coupler eventually will slip....ending in fried clutches. ...or you willhave thump thump from the rear. This is a total firmware errance ...since the electronic steering CAN provide the AWD with steering data and avoid screeching the rear tires in a tight turn. I hope later years have improved this carbage software....

What's interesting is some other manufactures go into great detail on how their AWD functions. The better ones have coupler up front so driveshaft does not turn when in FWD mode. Also other vehicles use the vehicles yawl sensor along with steering position sensor, plus separate clutches for each rear wheel to tune cornering dip,etc. Kia has very little details published other than sales brochure level stuff, even in the service manual it basically says cornering mode is used when cornering, with no explanation of what it does. Normally when cornering w/AWD the rear wheels are activated 'partially' to correct under-steer and save a little tire wear, but usually not full traction. Appreciate the Reverse Engineering you are doing here...Hey the Sorento is priced as it is for a reason..
