Even GMC's own press room has conflicting information so it's no wonder the general press can't keep things straight. This could be a reflection of plans that have changed over time.

And from October 21, 2020:Ultium-powered EVs are designed for Level 2 and DC fast charging. Most will have 400-volt battery packs and up to 200 kW fast-charging capability while our truck platform will have 800-volt battery packs and 350 kW fast-charging capability.

EDIT: Do the above quotes actually reflect a change? Or is the latter simply more precise in its wording?HUMMER EV will have the ability to take advantage of the industry’s fastest 350-kilowatt DC fast chargers4. This vehicle will offer a GM-estimated 350+ miles7of range based on preliminary testing, with a unique ability to switch its battery pack from its native 400-volts to 800-volts for charging. A disconnect unit and mechanization within the pack enables the battery to switch from “parallel” to “series,” allowing it to add nearly 100 miles of range in 10 minutes of charging8.
The Ultium battery system will control the electrical currents at the charging station via clever algorithms that ramp down the current and switch to the other half of the pack, when necessary, and increase the rate of charge. The charging system is also designed to support legacy 400-volt charging infrastructure, without the need for a converter box or other accessories, allowing HUMMER EV to use a variety of charging stations.
