I really would find an offroad E Tograc interesting and fun, especially when you could compare it to the offroad potential of gasoline or diesel Togracs. EDIT: And electric offroads part for the Vivace, too. It could really use a independent but not widebody suspension with an offroad and rally version (adapted for the higher mass of the vehicle) Estimated requirements: Adaptive E-Struts. Basically just like the regular adaptive struts but more weight bearing capacity due to the heavy battery pack Adaptive E sway bars/other suspension components if required. Changed final drive to allow for more power output at very low speeds. E-Dashboard requires addition of offroad I would guess that the most workload intensive and complex issue is going to be the electric offroad ESC/Drive mode. Being basically two motors that are not mechanically linked should in principle allow unrivaled independent axle control. It however might require the aft motor knowing what the front one does right now and vice versa. And then the correct decision in motor and E-diff control. I can only imagine how complex this would be. Thank you for consideration.
The eDiff logic is absent on the electric differentials because of this, you need to add them. More information.
