That is mind boggling fast. I wonder what charging speeds will hit in the next 5 years?
No, it is not. You don't understand the concept of C rate. The battery in the Bummer is 210 kWh (212.7 in EPA filing), 3.5 times as large as that in our 2017 Bolt, or that of over half of the Teslas sold this year.
GMC filed a report to the EPA revealing a 329-mile range, 47 MPGe combined efficiency, and 9063-pound curb weight.

To meaningfully compare the DC charge rate of a Bolt or standard range M3, you would need to divide that 303 kW by 3.5...86.6 kW. There are many new EVs that do that, or better. Another fair way to compare them is EPA MPGe. Ford matched the Bummers EPA MPGe in 1999.

The Bummer gets 1.55 mi/kWh vs the Bolt's 4.0 mi/kWh EPA rating. This means, per mile of range per minute, a Bolt at 55 kW is equivalent to 142 kW already.
The only thing mind boggling about the Bummer is the fact that GM is making them, and people are buying them.
