As a small, efficient car platform, I don't think that Ultium and BEV3 will be required for the Bolt EV. Obviously, Ultium has advantages, but a reconfigured BEV2 platform with NMCA batteries would put the Bolt EV ahead of anything we see on the road today. Probably 500 miles of range and 200 kW charging for under $30,000. I think most people would be happy with that.3. Updated Bolt based on Ultium and BEV3 platform !
