HERE’S WHAT WE KNOW ABOUT THE MODEL 3

When will it go on sale?

Tesla has said it expects to start Model 3 production at its Fremont, California, factory at the end of 2017. But the company has a history of delays. The Model X, which went on sale last fall, was initially due to go on sale in early 2014. Musk said last month that the Model 3, unlike the Model X, is designed for “ease of manufacturing.” Still, some analysts are doubtful. Morgan Stanley auto analyst Adam Jonas thinks Tesla won’t start building the Model 3 until the end of 2018.

Who are its competitors?

General Motors is set to start selling the Chevrolet Bolt electric car at the end of this year, a full year before the Model 3. The Bolt will have a similar price tag and a 200-mile range. Hyundai’s Ioniq, which has a 110-mile electric range and could match Tesla on price, goes on sale this fall. Audi will follow with an electric SUV in 2018. Musk said last month he’s not worried. He thinks the Model 3 will compete most directly with small luxury cars like the Audi A4 and the BMW 3 Series.

How did Tesla make the Model 3 less expensive?

Cheaper batteries. Tesla previously assembled its battery packs with battery cells made in Japan by Panasonic Corp. But Tesla and Panasonic are building a massive, $5 billion factory in Nevada which will supply batteries for the Model 3. Tesla says the scale of the factory will lower the cost of its battery packs by 30 percent.
