This is only true for somewhat old and obsolete Tesla superchargers, like V1 and V2. Since the introduction of Supercharger V3 they're all 400-1000V, so any car, with any internal voltage can charge at their rated speeds.
I believe you've mixed up the versions. That's only true for Supercharger V4, not V3. V3 did not support high voltages. V1 and V2 did not speak the CCS protocol so they were even more obsolete.
