Very cool, unfortunate Kia/Hyundai went 400v for their smaller vehicles.

Software defined vehicles?

This is still vaporware, can’t compare a platform currently in mass production to something that realistically might be available for people to buy in five or six years.

It's the future unfortunately, people want features and bug fixes OTA. People want their peace of mind for 2Y between services and not have to go before that for software fixes (I cannot think of a single modern EV that didn't have a software update to fix some issue)

Well the charfing speed for Kia/Hyunday on a 400V system is far from being limited by the voltage.

In fairness, if there are going to be bugs, I'd rather have them fixed without me having to go to a dealer. So that doesn't sound like a problem.
Seems rather weird to refer to the ability to receive updates as "software defined". Is this really the term we're going with?

Software defined goes beyond just OTAs of course, but you actually need a lot of interconnection just to make OTAs possible, since all the relevant modules have to interconnected, including to the infotainment system just to make this possible.
As well as software failsafes should a update go wrong, the system has to be able to roll back independently.

No, SDVs mean that instead of a bajilion microcontrolers, there is a brain (a normal CPU) that handles all the load that the microcontrolers had, for example, electric windows, 360 view camera, ADAS, etc

Thinking ahead, 800v is the way forward and is fast trickling down to smaller and smaller vehicles, best to get ahead of the curve and adopt it now. Costs for the components will drop substantially in years to come anyhow.

There was an [article in Autocar about the EX60 being software-defined](https://www.autocar.co.uk/car-news/electric-cars/volvo-ex60-first-impressions-europes-only-true-software-defined-vehicle), here are some of the comments from Volvo “engineering chief” Anders Bell:
*“In previous, domain-based cars, systems like lighting, steering, braking were all controlled by ECUs [electronic control units] that came to us from suppliers,” he said. “It’s a bit of a simplification, but in essence our job was to make all those black boxes communicate with one another without any hitches.”*
*According to Bell, every time you wanted to add a new function, you had to add new ECUs and lots of cross-wiring, which increased complexity and weight and took up space. “What we now have is a much more efficient open network with its software centralised. As we add functionality, we can integrate [additional features] into the car much more easily.”*
*He added that this approach saves “kilometres of wiring and bucketloads of ECUs”. The result, he said, is an EX60 with D-segment exterior dimensions but the cabin space of an old-style E-segment model.*
