Tesla Motors Inc (NASDAQ:TSLA) will premiere its low-end electric sedan, the Model 3, in few days. The $35,000 vehicle is expected to hit the EV industry like a thunder storm with more than 100,000 reservations within 24 hours. After abandoning application to trademark Model E in 2014, CEO Elon Musk has finally moved ahead with Model 3 trademark to complete Tesla’s lineup – Model S-3-X-Y.

Electrek reported that Tesla has official filed an application to trademark Model 3 under “Automobile and structural parts” class. The application was submitted on March 18, and it is being reviewed. Description of the mark in the application is as follows:

“The mark consists of three equal length horizontal stylized lines in the manner of a horizontal stylized roman numeral III.”

Tesla has made no reference to the mark being similar to the “E” in its logo. Tesla officials, particularly Mr. Musk, have been calling Tesla’s third generation car as the “Model E,” which would have made Tesla’s lineup Model S-E-X-Y, with the existing models Model S and Model X, and the next model that is rumored Model Y. The company acquired Model Y trademark in late 2013.

During 2014 Shareholder Meeting, Mr. Musk disclosed that the “Model E” trademark was dropped after Ford Motor Company (NYSE:F) threatened “to sue for using Model E.” He even went on record stating that “Ford tried to kill SEX.”

Since then, Tesla has kept its Model SEXY hopes alive by turning E into 3.  The three horizontal lines are also similar to the Chinese character for 3, with equal length instead. The EV maker also used those three lines to advertise the Model 3 and in Model 3 invitations to guests.

The Model 3 event will take place at Tesla Studio in Hawthorne, California on March 31. Customers can reserve the vehicle by visiting their nearest Tesla store after 10 AM local time or wait till 8:30 PM the same day to reserve it online.
