Tesla's signature 17-inch display
Given Straubel's comments, we may end up seeing Tesla's large display in the Model 3 — or at least something very similar.
Electrek's Seth Weintraub also points out that the cost of designing a newer, less expensive middle stack could actually end up costing Tesla more money than going with the design they already use.
Autopilot hardware
During a Tesla event in October 2014, Musk said that all Model S cars going forward would be equipped with Autopilot hardware, which enables the company's semi-autonomous system.
Musk has also made it clear that Autopilot is a big focus for Tesla right now and that self-driving cars are the future.
All to say: it makes a lot of sense for the company to include Autopilot hardware in the Model 3. However, consumers will still have to shell out a few thousand dollars to turn the function on.
A range of 250 miles per charge
There's a good chance that the Model 3 will get a range closer that of the Model S 70, which is 240 miles per charge.
During a Tesla press conference in March 2015, Musk was asked about the range of the Model 3 and he hinted that it would be more than 200 miles per charge.
"Two-hundred miles is minimum threshold for an electric car. But it does need to be a true 200 miles," Musk said. "It's got to be 200 miles you can count on. And that is kind of a passing grade and anything below that is not a passing grade. But ideally, people are looking for a bit more than that, I'd say at least 20% to 30% more than that. So that is why we tend to favor a range of closer to 250 miles to 300 miles."
Retractable door handles
Tesla's retractable door handles are in a word, awesome. We're really hoping Tesla doesn't skip this feature in the Model 3. It may be silly, but it's a characteristic feature that makes Tesla's cars feel that much more futuristic than they already are.
Leather seats as an option!
There's speculation that Tesla won't offer leather seats in the Model 3.
According to a post on Tesla Motors Club by a member who goes by Mr Jones 390, Tesla's Model 3 will not have luxury features like leather seats.
Mr Jones 390 claims he spoke to an insider who shared the information with him.
We know that the Model 3 can't have everything that the Model S has, but we sure hope Musk doesn't take away leather seats as an option!
