Strigear Prius II
A car identical with Toyota Prius II, but with the original power train replaced with a Strigear power train, could consume 3.25 liter/100km, emit 76 g CO2/km and accelerate 0-100 km/h in 7.7 seconds.

Comments
The Toyota Prius has more electric motors (31+400 Nm versus 140+140 Nm; 30+50 kW versus 20+50 kW).
The Toyota Prius has lower battery peak power (approx 35 kW versus 55kW). For acceleration purposes this difference is of minor importance as the Toyota vehicle during acceleration must allocate part of Motor 2 power (total 50kW) to transfer part of the engine power (57 kW) to the tires. Because of the mechanical properties of the planetary system used by Toyota, part of the Toyota engine power is always passed to the tires through motor/inverter 1 and 2. As an example, if 20 kW of the engine 57 kW is passed though motor/inverter 1 and 2, the motor/inverter 2 has only 35 kW capacity left, and can therefore only utilize 35 kW from the battery.
The Strigear system has both motors and the engine in mechanical parallel and can therefore easily use 55 kW of battery power as the motors can handle 20+50 kW and the engine power goes directly to the tires mechanically.
