Again, thanks so much for the info. I remember reading - probably here - that the G2 had "torque vectoring", but no idea how that was executed. Good stuff.Yes. While both systems use two variable clutches to send power to the rear wheels before front wheel slip is detected, there are several differences in the fundamental design and operation.
- VTM-4's clutches are engaged using electromagnets and balls rolling up a ramp. iVTM-4's clutches are engaged with using hydraulic pressure from an electric pump and controlled through solenoid valves.
- VTM-4 has a 1.7% overdrive. iVTM-4 has a 2.7% overdrive.
- VTM-4 operates the left and right clutches in parallel. iVTM-4 operates the left and right clutches independently for torque vectoring (helps turn the vehicle).
