SF Motors set sights on EV mass production with latest R&D testing facility
Santa Clara based electric vehicle startup SF Motors is opening up a new full-scale R&D center in Silicon Valley. SF Motors was founded in January 2016 after a large investment from Sokon Motors, a large Chinese automotive company. The company’s new 130,000 sqft research and development facility will be located in Milpitas, CA, roughly 6 miles away from SF’s headquarters.
The new facility, which is expected to be completed in Q4 ’18, will be capable of “small batch” manufacturing and development of manufacturing processes. The company is focusing on battery, powertrain, and autonomous vehicle development at the facility.
“Adding to our existing R&D labs, this new facility will conduct extensive design validation testing and small-scale manufacturing necessary to ensure a smooth transition to mass production of our batteries and electric powertrains, which are key components of our vehicles,” said SF Motors CTO Yifan Tang.
Yifan Tang joined SF Motors in February 2017. He was previously the technical lead on Facebook’s high-altitude long-range aircraft aimed at beaming internet across the globe. Before Facebook, Tang was VP of Drivetrain Engineering at Lucid Motors for three years and Principal Motor Technologist at Tesla for five years. During his time at Tesla Tang designed the motors for the Roadster, Model S, Mercedes B-Class/Toyota Rav4, and the prototype Model X AWD. Tang has a Ph.D. in electrical engineering from The Ohio State University and 35 U.S. patents.

In October 2017 SF Motors acquired Tesla co-founder Martin Eberhard’s battery module startup evINIT for $33M. Eberhard is now Chief Strategy Officer at SF Motors and the former CEO of evINIT, Mike Miskovsky, is Chief Development Officer. Eberhard served as the CEO of Tesla in its early years until late 2007.
Closing the loop from R&D to Manufacturing
SF Motors’ CTO Yifan Tang tells Teslarati that the new facility will help “close the loop from R&D to manufacturing,” and help accelerate the company to mass production. Tang describes the new facility as a key part of SF Motors strategy as they push forward to mass production.
According to SF Motors, the company is already prepping manufacturing facilities in the U.S. and China. SF Motors purchased a 675,000 sqft plant in Indiana from AM General in November 2017. The company also has a massive factory in Chongqing, China, with nearly 8.4M sqft of manufacturing space that’s capable of producing 200,000 vehicles per year.

SF’s Tang emphasized that the company’s abilities to produce small-batch trial production at their R&D facility will differentiate itself from other automotive manufacturers. The company plans to also produce battery cells at the facility and will test different cell configurations, modules, and battery pack sizes.
SF plans to produce a wide range of vehicles, and the ability to tweak cell chemistry along with module configurations will allow them to produce battery packs that are optimized for cost efficiency and performance.
The new R&D facility will house roughly 100 employees, but its proximity to the company’s headquarters allows the company to shift employees back and forth. “Drawing on our global business model and decades of manufacturing experience, locating this facility near our Silicon Valley headquarters will strategically ensure quality and efficiency as we prepare to bring our intelligent EVs to market,” Tang said in a press release.
SF Motors plans to start trial production of their vehicles at the end of this year.
Update at 10:35 am PT: An earlier version of this article incorrectly stated that SF Motors was a subsidiary of Sokon Motors. Sokon Motors was a large initial investor in SF Motors, but does not wholely own the company.

Tesla lands approval for Robotaxi operation in third U.S. state
On Tuesday, Tesla officially received regulatory approval from the State of Arizona, making it the third state for the company to receive approval in.
Tesla has officially landed approval to operate its Robotaxi ride-hailing service in its third U.S. state, as it has landed a regulatory green light from the State of Arizona’s Department of Transportation.
Tesla has been working to expand to new U.S. states after launching in Texas and California earlier this year. Recently, it said it was hoping to land in Nevada, Arizona, and Florida, expanding to five new cities in those three states.
On Tuesday, Tesla officially received regulatory approval from the State of Arizona, making it the third state for the company to receive approval in:
BREAKING: Tesla has officially received approval from the Arizona Department of Transportation to launch its Robotaxi service on public roads in the state!

Tesla has also been working on approvals in Nevada and Florida, and it has also had Robotaxi test mules spotted in Pennsylvania.
The interesting thing about the Arizona approval is the fact that Tesla has not received an approval for any specific city; it appears that it can operate statewide. However, early on, Tesla will likely confine its operation to just one or two cities to keep things safe and controlled.
Over the past few months, Robotaxi mules have been spotted in portions of Phoenix and surrounding cities, such as Scottsdale, as the company has been attempting to cross off all the regulatory Ts that it is confronted with as it attempts to expand the ride-hailing service.
It appears the company will be operating it similarly to how it does in Texas, which differs from its California program. In Austin, there is no Safety Monitor in the driver’s seat, unless the route requires freeway travel. In California, there is always a Safety Monitor in the driver’s seat. However, this is unconfirmed.
Earlier today, Tesla enabled its Robotaxi app to be utilized for ride-hailing for anyone using the iOS platform.

Tesla ride-hailing Safety Monitor dozes off during Bay Area ride
We won’t try to blame the camera person for the incident, because it clearly is not their fault. But it seems somewhat interesting that they did not try to wake the driver up and potentially contact Tesla immediately to alert them of the situation.
A Tesla Robotaxi Safety Monitor appeared to doze off during a ride in the California Bay Area, almost ironically proving the need for autonomous vehicles.
The instance was captured on camera and posted to Reddit in the r/sanfrancisco subreddit by u/ohmichael. They wrote that they have used Tesla’s ride-hailing service in the Bay Area in the past and had pleasant experiences.
However, this one was slightly different. They wrote:
“I took a Tesla Robotaxi in SF just over a week ago. I have used the service a few times before and it has always been great. I actually felt safer than in a regular rideshare.
This time was different. The safety driver literally fell asleep at least three times during the ride. Each time the car’s pay attention safety alert went off and the beeping is what woke him back up.
I reported it through the app to the Robotaxi support team and told them I had videos, but I never got a response.
I held off on posting anything because I wanted to give Tesla a chance to respond privately. It has been more than a week now and this feels like a serious issue for other riders too.
Has anyone else seen this happen?”

The driver eventually woke up after prompts from the vehicle, but it is pretty alarming to see someone like this while they’re ultimately responsible for what happens with the ride.
We won’t try to blame the camera person for the incident, because it clearly is not their fault. But it seems somewhat interesting that they did not try to wake the driver up and potentially contact Tesla immediately to alert them of the situation.
They should have probably left the vehicle immediately.
Tesla’s ride-hailing service in the Bay Area differs from the one that is currently active in Austin, Texas, due to local regulations. In Austin, there is no Safety Monitor in the driver’s seat unless the route requires the highway.
Tesla plans to remove the Safety Monitors in Austin by the end of the year.
Tesla has officially opened Robotaxi access to everyone and everyone, but there is one catch: you have to have an iPhone.
Tesla’s Robotaxi service in Austin and its ride-hailing service in the Bay Area were both officially launched to the public today, giving anyone using the iOS platform the ability to simply download the app and utilize it for a ride in either of those locations.
It has been in operation for several months: it launched in Austin in late June and in the Bay Area about a month later. In Austin, there is nobody in the driver’s seat unless the route takes you on the freeway.
In the Bay Area, there is someone in the driver’s seat at all times.
The platform was initially launched to those who were specifically invited to Austin to try it out.
Tesla confirms Robotaxi is heading to five new cities in the U.S.
Slowly, Tesla launched the platform to more people, hoping to expand the number of rides and get more valuable data on its performance in both regions to help local regulatory agencies relax some of the constraints that were placed on it.
Additionally, Tesla had its own in-house restrictions, like the presence of Safety Monitors in the vehicles. However, CEO Elon Musk has maintained that these monitors were present for safety reasons specifically, but revealed the plan was to remove them by the end of the year.
Now, Tesla is opening up Robotaxi to anyone who wants to try it, as many people reported today that they were able to access the app and immediately fetch a ride if they were in the area.
We also confirmed it ourselves, as it was shown that we could grab a ride in the Bay Area if we wanted to:

The launch of a more public Robotaxi network that allows anyone to access it seems to be a serious move of confidence by Tesla, as it is no longer confining the service to influencers who are handpicked by the company.
In the coming weeks, we expect Tesla to then rid these vehicles of the Safety Monitors as Musk predicted. If it can come through on that by the end of the year, the six-month period where Tesla went from launching Robotaxi to enabling driverless rides is incredibly impressive.
