Hummer EV - Extended Range Option?

[super8]

While playing around with a new Hummer EV build this morning I noticed a new option for the extended range option. The extra range is quite impressive!

Wow, this has to be a new option because I didn't see it a couple of months ago when I built mine online. With an estimated 381 miles of range that's a must-have option for me!
