Tesla Motors, Inc. is an American company that designs, manufactures, and sells electric cars and electric vehicle powertrain components. Tesla Motors is a public company that trades on the NASDAQ stock exchange under the symbol TSLA. In the first quarter of 2013, Tesla posted profits for the first time in its history.Tesla first gained widespread attention following their production of the Tesla Roadster, the first fully electric sports car. The company's second vehicle is the Model S, a fully electric luxury sedan, and its next two vehicles are the Models X and 3.Tesla also markets electric powertrain components, including lithium-ion battery packs to automakers including Daimler and Toyota. Its CEO, Elon Musk, has said that he envisions Tesla Motors as an independent automaker, aimed at eventually offering electric cars at prices affordable to the average consumer. Pricing for the Tesla Model 3 is expected to start at US$35,000 before any government incentives and deliveries are expected to begin by 2017. Wikipedia.

An ultrasonic sensor assembly is placed against an inside surface of a panel for sensing objects on an opposite side of the panel and includes an ultrasonic sensor, a preload structure, a coupling element, and a damping material. The preload structure applies a preload on the ultrasonic sensor toward the inside surface of the panel. The coupling element interfaces between the ultrasonic sensor and the inside surface of the panel. The damping material is placed against the inside surface but not where the coupling element interfaces between the ultrasonic sensor and the inside surface. The coupling element may include a matrix material that is reinforced with a filler.
