I know you won't be using this as your camper tug, but my experience towing a 7x4 with the Aurion was hilarious! One upon a time I had to progress up a slight incline at the back of our home (actually a public park that we backed onto) with the trailer on, one wheel on the concrete footpath and the other front wheel on the grass edge.
Now this was a narrow area and I had no sideways latitude, it had to be one wheel on the concrete the other on the grass. The grass was wet from dew. Well, the Aurion "failed to proceed" due to the determined traction control! No way would it get the three car lengths along the pathway to the road.
No choice, but to back down the track, put it back into my yard and wait for the dew to evaporate and traction could be had. Just saying that the traction control (non switchable) is great to harness that eager 200kw, but a Shit in a situation like this.
Incidentally there is a very convoluted and exasperating procedure to switch off the traction control that involves a series of handbrake and foot brake applications- Google it if you need it. Still a great car though!
Cheers! Andrew
