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.
