> 710kg for the Deutsche vehicle is only for the payload, that doesn't include the weight of the vehicle
for StreetScooter Work
Curb/Unladen Weight: 1,275 kg (2,811 lbs)
Max Laden Weight (Gross Vehicle Weight Rating): 2,130 kg (4,696 lbs)
NGDV with an ICE (according to the OP)
Curb/Unladen Weight: 2,523 kg (5,560 lbs)
> I found a PDF fact sheet for the vehicle
That datasheet appears to be for the Work L which is a different model: "Shown in September 2016 at the IAA Commercial Vehicles trade fair, the Work L prototype is a longer and slightly higher vehicle with almost double the cargo volume"[0]
> I wouldn't be suprised if that comes down to a combination of capacity, safety requirements, and maybe top speed needs in the US compared to the average European city
I'm not able to judge capacity or safety requirements, but the Work's maximum speed is 120 km/h (75mph).
