Typical belt drive motor generators are limited in torque, even with designs up to 12 kW. Figures in the 50 - 60 Nm range are used in association with recuperation torque. I sense the belt performance limits the torque, both as motor and generator.

Gen 2 sounds like a great improvement by eliminating the starter motor and the belt system, which appears to be weak links(according to posts from other forum members).
I do wonder if Gen 2 requires bigger MH battery than Gen 1, and if there is extra wear and tear on that battery.
