Tesla’s supercharger network is going to get way, way bigger in the next year, but on Wednesday, CEO Elon Musk let on that some of the improvements might be on a different scale than another few charging points.

During a question and answer session of Tesla’s second quarter earnings call, Musk said that Tesla was on the verge of unveiling its first Mega Supercharger station, a combination of a gas station and a luxury-class rest stop, packed to the brim with amenities to keep a Tesla road tripping family occupied while their electric car fills its battery back up at a supercharger.

Musk was responding to a question from Colin Langdon, an analyst at UBS, who wanted to know how Tesla assessed the numbers and needs of its supercharger network going into the mass production of the Tesla Model 3. Musk explained that expanding the network, which he claims will triple by the end of 2018, is more than just adding more superchargers, it’s also figuring out where the superchargers should go. The network is divided between superchargers that are placed strategically on major highways to enable longer distance trips, and ones in city centers that serve the daily demands of customers in high traffic areas (Musk mentioned the the uber-rich, super-dense neighborhood of Malibu in Los Angeles specifically). To make the experience even better for Tesla A-listers and owners, Musk said the company was planning a different kind of supercharger as well.

“We’ll also be experimenting with our first, I dunno what you’d call it, mega Supercharger location, like really big supercharger location with a bunch of amenities so we’re gonna unveil the first of those relatively soon.” Musk said. “I think we’ll get a sense for how cool it can be to have a great place if you’ve been driving for three four hours to stop, y’know have great restrooms, great food, amenities, hang out for half an hour then be on your way.”

John McNeil, Telsa’s president of global sales and service, chimed in, explaining that in some places, particularly the supercharger stations in between cities, still have a lot of open slots much of the time, meaning that the network isn’t operating at full capacity even at its current size. This, he said, was a good sign for the network being able to handle the influx of Model 3s, which are surely coming as the company ramps up production.

In the hours before the official reveal, Tesla showed not one, but two trucks to journalists ahead of the unveiling: a standard model and another with an aerodynamics package. There were tense moments leading up to the reveal, with Tesla employees buzzing around nervously.

There have been rumors that Tesla is developing its own chip optimized for self-driving applications ever since we reported on the automaker quietly hiring legendary chip architect Jim Keller from AMD last year.

Now CEO Elon Musk finally confirmed the rumor – specifying that Tesla is working on its own new AI chip and that the effort is led by Keller.

At the Conference on Neural Information Processing Systems (NIPS) yesterday, Musk held a fireside chat with Tesla’s new Director of AI and Autopilot Vision, Andrej Karpathy, Jim Keller, Tesla’s Vice-President of Autopilot Hardware Engineering, and Shivon Zilis, a partner at Bloomberg Beta and a project director for Musk’s office.

According to people at the event, the discussion revolved around Tesla’s artificial intelligence work and it was seemingly a recruiting effort for the company.

But Musk also made a few interesting comments, including a confirmation that Tesla is working on its own AI chip to enable self-driving technology.

The CEO confirmed that Keller is behind the effort, which he believes will result in “the best custom AI hardware in the world.”

Keller has an important reputation in the hardware world after having been a key player in the creation of several architectures, like Athlon K7 and K8 at AMD, before developing Apple’s A4 and A5 processors, which powered most of Apple’s mobile devices from 2010 to 2012. He later came back to AMD and led the design of the company’s latest chip architecture.

After quietly joining Tesla in late 2015, we reported that the automaker poached a team of chip architects and executives from AMD following Keller’s hire.

That’s when the speculation that Tesla is working on its own chip, presumably for self-driving, started. It was also in the middle of Tesla changing hardware from Mobileye to Nvidia for its Autopilot program.

Tesla is now up to its Autopilot ‘2.5’ hardware suite with more computing power for autonomous driving based on Nvidia’s Drive PX platform.

Musk previously said that he expects Tesla’s 2.0 and 2.5 Autopilot hardware suites to enable “fully self-driving”, but if it doesn’t, Tesla will replace the computers in those vehicles for free.

And now we know that Tesla is working on computers with its own AI chips.

When asked about potential improvements at the event yesterday, Keller said that there are opportunities to remove overheads between components for specialized hardware, which Musk says could result in 10 times the current power for a fraction of the cost.

Computing power inside vehicles is becoming increasingly important and like several other generally outsourced vehicle components, Tesla seems dead serious about bringing it in-house.
