Affordable car with latest technological advancement and features

I want to know more about Toyota Prius 2015. What are the specifications and new features offered by this car? What is the Plug in hybrid program for? What is the purpose and benefits of Automatic climate control? How does its advanced voice recognition works? What is Dynamic Radar Cruise Control (DRCC)? With all this combined, how beneficial it is for any driver looking into maneuverability and safety? With terms of security, is there any added feature for this car? Can use my smartphone with this car?
