Neither of them are actually 4×4 in the proper sense, they are partial all wheel drive. It only comes on below a certain speed (20kph) if the car thinks it’s needed, there is no permanent all wheel drive from software version 4.0 onwards.
As for the ID4 vs the Enyaq, I sat in an ID4 and went for the Enyaq, there was simply no comparison in build quality or design. I’d also look at the new Elroq, almost identical to the Enyaq but with a slightly smaller boot and shorter overall length, wheelbase is the same though. There is an 85X version coming at somewhere near the end of this year, the RS version is coming first.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
