The tweet comes after Musk said in May Tesla was on schedule to kick off production of the sedan next month.

Here’s what we know so far about Tesla’s Model 3:

Model 3 Video

In March, Musk tweeted a video of a candidate version of the Model 3 taking its first drive.

Here’s the short clip he shared:

The video shows the car smoothly accelerating and suddenly coming to a stop. At the time Musk said 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 added about the car.

Tesla’s site explained further on the difference between the Model S and Tesla Model 3.

“Model 3 is smaller, simpler, and will come with far fewer options than Model S, but it makes driving feel effortless and offers a good range of at least 215 miles for our starting model,” the site said.

Tesla Model 3 Battery Charge

The Model 3, the company’s first mass-market car, will be able to fit five passengers and will run 215 miles on a full charge. Tesla set an ambitious goal of reaching 10,000 superchargers by the end of this year. There are currently 5,000 superchargers worldwide that Tesla has installed for car owners. The new superchargers will be built along busy roads and will be made large enough to fit multipple cars. This month, Musk said on Twitter Tesla plans to disconnect “almost all” its superchargers from the electricity grid and that they “are being converted to solar/battery power.”

Model 3 Design

Tesla’s Model 3 will feature a glass roof windshield, like the Model X. The sedan will come with Falcon style wing doors and a “spaceship” dashboard, Musk previously said on Twitter.

Tesla reportedly teamed up with LG for a 15-inch landscape touchscreen for the dashboard of the vehicle.

Price, Reservations, Delivery

The Model 3 is Tesla’s most affordable car yet, with a starting price of $35,000. Tesla will offer a semi and fully autonomous versions of the vehicle. The fully autonomous model with Autopilot 2.0 will cost about $50,000. If you’re interested in getting a Model 3, you can reserve a car for $1,000 on Tesla’s site.
