P3 design with CVT
Output connected Electric Machine: • PMSM (future SRM) • Chain ratio to wheels 12V e-pump to retain some CVT functions in EV mode variator
Uncompromized vehicle integration
• Powertrain length = identical to non-hybrid • No changes to crash structure of vehicle body • Height similar to engine block
