I've had owned a variety of vehicles over the years, most of them high performance and a few were front wheel drive like my tuned Volvo 870R. Even with unequal half shafts and boatloads of torque, it did not pull like this. My previous car was a GMC Yukon Denali that is roughly the same size, weight and power yet it tracks straight down the highway even under full throttle. I also currently own a BMW X5 and a VW Touareg which are also only slightly smaller than the LR4 and they track straight down the highway under full throttle. The difference between these vehicles that might contribute to the pulling in the LR4 is that it uses 50/50 torque split where the others shift more than 50% of the torque to the rear wheels.
While the LR4 is a better off road vehicle than any of the others I own, it is the worst of them on the road. Unfortunately, that is where it spends more than 99% of its time.
Land Rovers in general, and my family have owned many generations of them, are built for farms/estate/road and off-road use and all drive this way (minus the RRS.) They are engineered to have softer tolerances for off-road use and will never drive like a car on pavement. They are built for a purpose and those who purchase them know this before purchasing them. And the general play/softness (no steering wheel kick-back for example) is important for off-road use, because if the steering/suspension/etc. is too tight/taught, it will break. There is a real reason behind the engineering.
And I personally thank Land Rover for not throwing out these philosophies, because it's what makes Land Rover, well, Land Rover. I use my Land Rover for camping in Death Valley with my Son, taking on complex back-trails, going up to Lake Tahoe, hauling around a family of 7 when the visit, and as an occasional work horse for the home. And this is the reason why I purchased a Land Rover to begin with, for these needs. Not for commuting or doing some errands around town. And best of all, and just like the Land Rover "Go Beyond" ads, "Dirty is better than Clean."
Anyway, most of the SUVs/cars you mention are really pavement going cars which can be used for some very light off-road use. Even the Denali you mention is mostly engineered for pavement use. And if any of these were ever taken off-road at Land Rover levels, they would break quickly. Because they're engineered with less off-road tolerances, taught and tight for street use, and don't have much or any play. Maybe the Land Rover LR4 wasn't the best fit for you and your needs.
If I was you, and taking into considering that you need something that's going to be 99% on road, I'd keep the LR4 for a while, and after you've outset your depreciation, trade it in for an Audi Q7. To me, that sounds like the perfect SUV for you, it is highly engineered, very executive, drives superbly on pavement, can tackle some light off-road situations, and provide the luxury and comfort of a true European brand.
