This is almost certainly the i8 1.5L 3 cyl that makes 220 hp. The i3 rex engine would explode trying to power such a large truck, 220 hp would probably keep it moving 80 mph down the highway with a dead battery. The i3 engine barely keeps my i3 going 65 mph, long hills are almost nogo. And the i3 is like half the size and way more aerodynamic.
I am not following this truck,
As you correctly said , powering on just rex alone is not sufficient even for i3. That is why , we need a rather large battery buffer or a larger engine .
If you need the capability to run on a dead battery then , those vehicles are called plug-in-hybrids and not electrics. Volt , Prius are correct examples , and not the i3 rex.
They called the truck electric and not hybrid, so it needs more than a dead battery as buffer.
The marketing department does spin things out incorrectly some times.
