Up to 360 km (224 miles) range with larger 79 kWh battery configuration.
That range applies to L2H1 (136” low roof) on NEDC cycle, which is primarily low-speed urban driving with frequent stops. How that range would compare to this van at steady highway speeds is a good question.
About 20% less EV's don't do well at highway driving no regenerative braking this is a guess on the low end, but all EV's have the degradation when driving highway. And you only want to charge the batteries on a daily basis to 90%, so that will cut into your range also. When fully charging to 100% the batteries will grow dendrite's these are what cause battery fail, the million mile battery should solve this problem.
