Tesla unveiled its latest electric car, the Model 3, almost a year ago, but Elon Musk on Friday provided a peek at an almost-final version of the vehicle.

Musk posted a short video to Twitter showing a "release candidate version" of the Model 3. As you can see below, this thing can accelerate with a quickness.

Musk also clarified something: The Model 3 isn't a successor to the Model S. Instead, he wrote, "Model 3 is just a smaller, more affordable version of Model S w less range & power & fewer features," and clarified that the "Model S has more advanced technology."

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

Unveiled on April 1, 2016, the Model 3 has a starting price of $35,000, making it Tesla's most affordably priced model. Musk at the time said the base version of the Model 3 would go from zero to 60 miles an hour in less than 6 seconds, and drive for at least 215 miles on a single charge.

On Twitter today, he also revealed an interesting detail about the car: It was almost called the Model E instead of the Model 3. Check out what he had to say about that:

Just in case it's not so obvious to you why the company would want to call it Model E, consider that Tesla already has a Model S and Model X, Musk and Co. figured they'd round out the lineup with Models S, E, X. Instead, they have a slightly different version: S, 3, X.

This isn't the first time Musk has brought sexual innuendos into his product branding. Prior to revealing the Model S P85D back in 2014, Musk hyped up the announcement with a tweet saying it was "about time to unveil the D," setting off a firestorm of speculation and jokes.

Joining a field already filled with the likes of Lyft and Uber, Mercedes wants to help populate streets with its own robo-taxis. Mercedes’s parent company Daimler has partnered with automotive supplier Bosch to create its own system of self-driving vehicles, which the companies hope hit the streets by 2020.

Mercedes and Bosch are going above and beyond: Rather than simply creating a fleet of autonomous cars, the alliance seeks to create a shared network of self-driving robo-taxis that can be hailed through a smartphone app.

The companies’ new project plans to include both autonomous vehicles that require a human driver behind the wheel and ones that do not. The system and its fleet will be specifically designed for cities.

With Daimler’s expertise in auto manufacturing and Bosch’s technology and hardware, the companies are in a good position to make a dent in the market. Daimler’s Mercedes-Benz has already been working on developing its own self-driving cars. And the German automaker has already gotten a taste of the car-sharing business with its company car2go and its mobility service subsidiary Moovel Group, which owns route planning startup RideScout and taxi booking app Mytaxi.
