Did you think that Tesla was done with surprises this year after name-dropping the Model 3? Far from it. The company's Elon Musk has just teased the unveiling of what looks like another vehicle, the "D," on October 9th. There will also be "something else" in store, he says. Just what either of those entail is still a mystery, although Musk has previously hinted that the third generation of Teslas would involve both the long-expected "budget" sedan and an SUV smaller than the Model X. There's a real possibility that you'll hear about one or both of those EVs in a week's time.
