Tesla’s vehicule lineup has expanded tremendously over the past few years. Three years ago, the only car you could purchase from Tesla was the Model S. These days, Tesla offers the Model S, the Model X, and of course, the Model 3. Not one to rest on its laurels, Tesla over the next few years has plans to introduce a next-gen Roadster, a crossover version of the Model 3 dubbed the Model Y, and a pickup truck. And last but not least, Tesla in the near future has plans to release the Tesla Semi, a semi-truck that has already garnered orders from a range of Fortune 100 companies. Tesla Semi production isn’t slated to begin until 2019 and it remains to be seen if the semi-truck will be subject to lengthy delays similar to what we saw with the Model S and the Model X. The release date aside, we’ve started to notice a distinct uptick in Tesla Semi sightings over the past few months. Most recently, a Tesla Semi prototype showed up at Tesla’s Fremont factory (via Electrek), prompting many people in the area to whip out their phones and fire up Instagram. A sampling of Tesla Semi photos can be seen below.
