200 KWH BATTERY PACK: The Hummer EV’s battery pack uses GM's new Ultium technology, a modular pack with flexible drive unit combinations that are scalable to build a wide range of trucks, SUVs, crossovers, cars and commercial vehicles, leading to an "EV for everybody," according to GM. US auto media reported that the Hummer Edition 1 uses a 200-kWh pack, which is huge. That's double the 100 kWh battery packs fitted on the biggest available Tesla, the Model X P100D.
