Tesla Model S The Tesla Model S is a full-sized all-electric five-door, luxury liftback, produced by Tesla, Inc., and introduced on 22 June 2012.[13] It scored a perfect 5.0 NHTSA automobile safety rating.[14] The EPA official range for the 2017 Model S 100D,[15] which is equipped with a 100 kWh (360 MJ) battery pack, is 341 miles (550 km), higher than any other electric car.[16][17] The EPA rated the 2017 90D Model S's energy consumption at 200.9 watt-hours per kilometer (32.33 kWh/100 mi or 20.09 kWh/100 km) for a combined fuel economy of 104 miles per gallon gasoline equivalent (2.26 L/100 km or 125 mpg‑imp).[18] In 2016, Tesla updated the design of the Model S to closely match that of the Model X. As of October 2017[update], the following versions are available: 75D, 100D and P100D.[19]
Tesla coil The Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891.[1][2] It is used to produce high-voltage, low-current, high frequency alternating-current electricity.[3][4][5][6][7][8][9] Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.
