"There's probably been times that ICE car designers wished they could put two engines in a car, one for acceleration and another for efficient highway MPG."
It's called an ICE transmission. Imagine what your ICE vehicle's fuel economy would have been if you had
just 1st gear to drive with at all speeds, i.e. starting from the a stop and cruising on the freeway at 60 MPH.
The hybrid further achieves ICE efficiency by placing the required acceleration on an electric motor versus
an ICE and basically only utilizes the ICE for cruising where the ICE achieves it's best efficiency/fuel economy.
Reports indicated that Tesla did consider using a transmission but that development never yielded.
The reason for the consideration was the high RPM needed for the max speed desired for the MS.
Now with a second motor and higher gearing, that issue could be solved and better optimization
of each motor for different demands.
