One of the major factors standing in the way of having the perfect electric driving experience is having to plug-in hybrid cards to charge the batteries. Daimler (parent company of Mercedes-Benz) and BMW are getting one step closer to that perfect experience by adding wireless charging. 

The companies are developing the technology together, which would make the handling of electric cars easier. The unplugged charging system has two components -- a primary coil in the floor plate that can be, for example, placed on a garage floor, and a secondary coil in the under tray of the car. Electricity can be transmitted at a rate of 3.6 kW completely contact free and with an efficiency rate of 90%. 

Mercedes-Benz is planning a fleet test on the S 500 Plug in HYBRID, which will be launched in September. The car boasts 325 kW of power and 650 Nm of torque. It can go from zero to 100 kph (62mph) in 5.2 seconds. This car will also mark the first luxury sedan with certified consumption below three liters for every 100 km (about 0.8 gallons per 62 miles).
