Default Capacitive sensor driver attention system

The current Audi traffic jam assist system requires the driver to apply brief torque on the steering wheel every once in a while to keep the system enabled if it doesn't sense your hands on the wheel. Early after the e-tron reveal last year there were reports that the US would get a capacitive steering wheel sensor that could detect your hand without having to apply torque. Has anyone been able to confirm this functionality in person or have more information about it?

Here is an article and video claiming this functionality:

Now that cars are being delivered, can someone confirm if the steering assist wheel sensor is torque based or capacitive? (i.e. does it require you to nudge the steering wheel on occasion to sense hands-on. Or can you just hold the wheel normally?

Thanks!

If it has capacitive touch registration it might explain that lack of heated steering wheel.

I do not know it has capacitive touch registration, but heated steering wheel is an option in EU.

I'm not sure where I heard it but it was specifically mentioned that it was the US cars that were getting the capacitive sensor. That lines up with what you're saying, although I don't feel closer to a definitive answer.

I found the source of this info. It was in the Electrek video podcast at the 9 minute mark.

Picked up my etron Edition One on Tuesday; I don't need to torque the steering wheel, so does that mean its capacitive? I will check on the heated steering wheel in a moment.

Are you holding it tight enough already for it to sense you?

Might be capacitive and if so, I love it. That's the way all these systems should work. The concept of tugging at the wheel every 30 seconds is ridiculous.

So, no heated steering wheel on the Edition One; at least I couldn't find any setting for it. So, combined with the fact that you just have to touch it "lightly" to make your presence known, I'd have to say it is capacitive.

I drove my Edition 1 for over 50 miles today ( on day 1), it is hard to tell. At first it felt like I have to press harder. but then I figured that if I keep lightly rubbing the leather part of the steering wheel, it doesn't complain. Therefore, I am now quite sure it is capacitance sensing. May be I should try a pair of Latex gloves :-)
