I'm afraid you misunderstood my comment. The Prius' electric motor is
not limited to 19kW output; that's the number you get if you subtract ICE power from total system power. But its actual electric motor max power output is 53kW, per Toyota. The current RAV4 hybrid has an electric motor that has a maximum 118hp//88kW, again per Toyota; the RAV4 Prime has to have a more powerful motor than 126hp to make combined 302hp vs. the regular hybrid's 219hp since they have the same gas engine. You can't just subtract the two numbers since the gas and electric motors have different torque curves and RPM ranges, and the transmission can vary those inputs with load; subtracting the numbers doesn't tell you anything about acceleration in electric mode or maximum power output in EV mode. We'll have to wait for Toyota's figures on those (if they even publish them; they don't for the Prius Prime).
