Full production of Tesla's long-awaited Model 3 will not happen until 2018, according to a presentation by the company's chief technical officer, JB Straubel.

The presentation — given last week at the EIA Conference in Washington, D.C. — features a slide saying a "$35,000 200-mile electric car is planned for 2018."

Initially, this looked to be a departure from the expected Model 3 timeline, which calls for the design concept to debut in the first quarter of 2016 with deliveries beginning in 2017.

But company representatives provided clarification to Bloomberg's Corey Johnson indicating that the slide was referring only to full production. According to Tesla, the company fully plans to debut the Model 3 concept in 2016 with initial production in 2017.

We recently learned that the Model 3 will actually be two cars: a crossover SUV and a sedan. Tesla is expected to begin deliveries of its Model X SUV in the third quarter of this year.
