I think the single motor version of the ID.4 is pretty similar to the B in terms of power. The AWD version does give a lot more oomph. That 50% extra power makes driving more fun too. While the interior leatherette looks a bit utilitarian, it is very comfortable. The armrests are tiny pieces that swing down or away. The design gives a particularly spacious feel, especially with the panoramic sunroof. This is one of the few models that provides a retractable screen too. The ID.4 , usually considered a crossover style, is bigger than the B, so it will feel more spacious in comparison. Rear seat legroom feels tremendous, and the hatch/trunk area is a fair bit bigger too.
The infotainment system has been widely criticized as not ready for primetime. It is true. It is glitchy, and the interface is not obvious. The phone app is about the same as the previous B app in terms of functionality. The Electrify America charging stations don't show up in a simple way. It's not quite as bad as the old Becker mapping system in the 2014 B that showed Electric gas stations if you scrolled down alphabetically past Citgo. Android Auto can work though, and most like that. CarPlay too. I think AA is pretty glitchy too though.
Still, all in all, the infotainment works, and it doesn't really affect the driving, and that's the main thing. It drives well and is often described as feeling "planted", meaning that it feels very stable, with very low roll in bends, and very tight steering. It is a great car to drive! I drove from Maryland to New Jersey and back for my first road trip in an EV. Charging at an Electrify America charging location in New Brunswick was simple and all I needed (I spent an hour there, but 35 minutes would probably have been enough). That's for more than 6 hours of driving at highway speed.
Other cars I've considered are the Audi Q4 etron, Audi etron, Tesla Model Y, Volvo XC40 Recharge and the Polestar 2, all on the more luxury end and the Chevy Bolt, the Nissan Leaf, Hyundai Kona EV on the low end. Most of these are pretty decent choices, depending on price. I don't like the seating at all on the Chevy Bolt and the Polestar 2, but I can see why others would go for any of these. The Audi Etron is the most premium of this list, I think, but pricing is much higher. The Audi Q4 ETron is the sister car to the ID.4 with similar features and specs. It's not available quite yet in the U.S., but that should be another great car, with a reasonable upcharge over the VW version for maybe a more premium interior and slightly different set of features and Audi's infotainment system instead.
