FWIW, Audi claims the eTron GT can charge at 800V, suggesting they’d get maximum charging speed on the v1 CCS you mentioned.
If they're doing the pack-reconfiguration technique that Taycan is doing, then they would be able to.
The fact remains that even 175kW chargers are extremely rare compared to superchargers.
Could be true, while above statement could be far in the rear view mirror soon too To name just one company; Fastned currently has 12 locations in the Netherlands (and 6 in Germany) that provide 175 KW charging service for cars able to charge at that rate. To place that number in perspective, currently there are 16 Tesla super charger stations in the Netherlands
The number to compare is not "stations", it's "chargers" and "stalls". Judging from this:
fastned station - Google Search
... Fastned stations are 2 charger / 4 stalls. The average Tesla Supercharger station has over 8 stalls and over 4 chargers. New superchargers are averaging over 10 and 5. In more densely populated / EV heavy areas, like the Netherlands, the numbers are much higher. Checking the Supercharger map for the Netherlands (incl. inactive (since an even higher portion of CCS stations are dead), and one under construction / nearly done station) I see:
2 / 1 (x1)
8 / 4 (x2)
10 / 5 (x1)
12 / 6 (x8)
16 / 8 (x3)
20 / 10 (x1)
24 / 12 (x1)
28 / 14 (x1)
Grand total: 244 stalls, 122 chargers. Versus 48 stalls, 24 chargers. And this is in the Netherlands, which has one of the highest concentrations of 175kW CCS chargers (if not the highest) in the world.
There's just no comparison to the Supercharger network when it comes to high-power chargers.
