With WTF engaged and right pedal on the floor... Does WTF stay "ON" past 60mph and what is the top end speed rating for the 1st Edition EV-1. Is it speed limited or restricted?

I would guess Hummer will be speed limited around 100 mph, just like all OEM trucks built today, its due to tire speed ratings, and blowout safety.

I will further promote this idea based off our current vehicles. GM is currently using Goodyear Wrangler Duratrac tires on most of our AT4 Sierra's. This seems to be there off road tire of choice. I imagine this will be what they use for the Hummer. It's an E1 on load range, so a 10 ply tire and considering the Hummer will be an 8 lug and heavy this sounds accurate. It's a 121 on Load index so each tire can carry 3197 pounds again enough to support the Hummer. The speed rating for the tire is up to 100mph.

Tires of this size to support the Hummer will be what limits our speed the most I believe. My Bolt is limited at 93mph. I wouldn't be shocked to see something similar on the Hummer to keep it away from that max threshold.

Yes, the tires are the limiting factor typically in truck design speed. I think Hummer will be limited to 100 mph, my gosh, calculate the energy the Hummer is carrying into a crash at 100 mph, whatever it hits does not stand a chance.

That is a very valid point as well.
