Lucid does today. Porsche's new battery likely could (but I bet they'll still keep the rated range at under 300 miles while overdelivering). And all of the other manufacturers have more capable batteries in terms of density and charging speed nowadays.Which competitor could do this?
It's purely about onboard battery capacity vs. weight & cost. Anybody can hit 500 miles. I'd rather have fast charging than more batteries.
Tesla could stuff in some more batteries and increase the range to 500 miles using their old overly inflated metrics. But they wouldn't be able to support the current required to support Model S / Plaid power with such a battery.
