The post didn't mention the fuel economy. It gets almost 40MPG and does not have a transmission(mechnical). 0-60 in 4 secs. Top speed is about 155mph.
Hybrid Synergy Drive Electronic controlled CVT works fundamentally different(no belt, pulley, and cones)from Honda/Nissan/Saturn CVT. The CVT function is achieved by cleverly engaging Internal Combustion Engine(ICE), Electric Motor, and Wheel in a planetary gear set. Planetary gear set can combine power from any two sources and output to the third source. At a given ICE RPM, increasing Electric Motor RPM would increase the Wheel speed. At a given speed (Constant wheel rotation), ICE RPM can be adjusted by changing the Electric Motor RPM, thus, achieving CVT functionality electronically!
Planetary gear can also split power from one source onto the other two sources. ICE power can be split into the Wheels and Electric Motor (aka electric generator). Therefore, you are driving the car and charging the battery at the same time. This enables Prius to take advantage of ICE "sweet spot" when you accelerate the engine RPM close to the "sweet spot". In that situation, the computer might put the ICE to the most efficient RPM and charge the battery. Mild hybrid such as Honda Civic can only route the power from the ICE to the Wheel and back to the battery through regenerative braking.
