Tesla CEO Elon Musk teased the upcoming Model 3 on Friday, by posting a video on Twitter of the “candidate version” of the vehicle taking its “first drive.”

In software terms, a release candidate is pretty much the final version of the product before it launches. This means Tesla won’t make major changes to the design and the Model 3 released to buyers will look quite similar to the one shown in the video.

The short clip shows the car smoothly accelerating and suddenly coming to a stop.

Here’s the video:

Musk’s tweet comes after he told investors last week in a conference call the Model 3 production was on track and that it was building the car’s Beta prototypes.

Musk also clarified people’s thoughts about the Model 3 on Friday in a series of tweets.

“Am noticing that many people think Model 3 is the 'next version' of a Tesla, like iPhone 2 vs 3. This is not true,” he said.

Musk also added the Model 3 will be a smaller and affordable version of the Model S, which has more “advanced technology.”

“Model 3 is like a BMW 3 series or Audi A4. Model S is like BMW 5 and 6 series, but much faster, more storage space + Autopilot,” he said.

“Model S will always be the fastest Tesla until next gen Roadster, which is a few years away,” Musk added in another tweet.

“Model 3 was going to be called Model E, for obvious dumb humor reasons, but Ford sued to block it, so now it is S3X. Totally different,” he added with a smiley face.

The Model 3, which fits five adults and goes 215 miles on a full charge, will start at $35,000. Tesla is expected to begin delivering the car for new reservations by mid 2018 or later, the site says. Those interested in getting their hands on a Model 3 can reserve a car for $1,000.
