Elon Musk posts Tesla Battery Day update, hints at mid-May event
Those who have been waiting for Tesla’s 2020 Battery Day will now have to wait a little longer. Tesla CEO Elon Musk announced that the event would “most likely” take place in mid-May, roughly one month after its originally intended date. “Hard to predict dates right now. Most likely postponed to mid May,” Musk wrote on Twitter as a response to a Tesla community member asking about the event.
The reason for the delay in the event seems to be related to the COVID-19 pandemic. This virus has halted production lines in Fremont and Buffalo and has caused the company to adapt to new delivery processes to deliver new electric cars to their customers. Considering that Tesla events usually involve presentations to groups of people, Battery Day may involve viewers being packed in a large room. Such does not conform to current social distancing suggestions to prevent the spread of the virus.
Tesla’s Battery Day will outline the company’s plans for battery development for future vehicles and energy solutions. Musk stated the event would be geared toward a review of Tesla’s cell chemistry, module and pack, architecture, and the company’s manufacturing plan that will detail how it can reach a terawatt-hour per year of battery production. “We have a very compelling strategy. I mean, we are super deep in cell. Super deep. Cell through battery,” Musk said.

Tesla’s ultimate goal with its cars is to reach price parity with its gas counterparts as soon as possible. Battery improvements would decrease the cost of vehicles tremendously, as the production of battery packs is one of the most expensive stages in EV manufacturing. Expectations suggest that Tesla has gotten its battery costs down to $100 per kWh, and Battery Day was widely speculated to be an event that discusses such a milestone.
Tesla has crafted a relationship with many cell manufacturers across the world, like Panasonic, which supplies the company’s lithium-ion vehicle batteries. In China, LG Chem and CATL are responsible for the task. The company has also made several acquisitions of battery research companies whose technologies can improve the quality of cells in the long term. One of these companies is Maxwell Technologies, whose research with ultracapacitors and dry electrode technologies could very well improve Tesla’s batteries in terms of quality and longevity.
This could lead to the development a “1-million mile battery,” which Tesla has predicted for its vehicles in the future. Researcher Jeff Dahn, a world-renowned battery specialist whose team at Dalhousie University, says that a battery capable of 1-million miles is more than feasible. This battery goal is attainable, especially considering the Dahn team’s development of pouch cells that have extended life.
Tesla held a similar event in 2019, called “Tesla Autonomy Day,” that outlined the company’s plans to complete its Full Self-Driving suite. However, it seems Tesla’s plans for 2020 are primarily focused on battery and energy storage, starting with Battery Day.
Fremont and Giga New York are poised to reopen on May 4, ending an over one-month shutdown. It is safe to assume that if this date is pushed back into late May or even early June, Battery Day could once again be delayed to ensure the safety of its attendees.
Electric vehicle maker Lucid Group has denied rumors of an imminent bankruptcy after a report from this morning sent the stock on a dramatic drop on Wall Street, seeing losses of more than 40 percent during trading hours.
Lucid’s Director of Communications, Nick Twork, responded to the report from Eletric-Vehicles.com, which stated the company’s restructuring advisor, AlixPartners, was asked to review two decisions: taking Lucid shares private or filing for Chapter 11 bankruptcy protection.
The report also claims AlixPartners told the Lucid board to “concentrate on Gravity production while improving its quality, and to temporarily hold back the Lucid Air, the sedan that has defined the company since its launch.”
Twork said:
$LCID The rumors are completely false. The company has sufficient liquidity to carry its operations well into next year, as recently published in its last quarterly filings, and it has not formed any special Board committee to explore the scenarios reported today. Our focus is…

Shares rebounded after the response to the report, halving its losses as the trading day neared 3 p.m. Eastern.
Lucid has struggled to get its sales off the ground and into more respectable numbers, but the company is in its early years, when things are hard to begin with. It is also backed by several notable investors, including the Saudi Public Investment Fund (PIF), which has nearly limitless money and likely would not ditch an investment of this size so soon.
Lucid shares were down just 14 percent at the time of publication, a far cry from the 55 percent its losses topped out at during the day.
A Tesla owner who purchased a Model S Signature Edition, one of the final 250 units of the all-electric flagship vehicle that the company discontinued earlier this year, is attempting to sell the car despite a no-resale clause that prohibits reselling for the first year.
The car is being sold by J&S Autohaus in Ewing, New Jersey, and is priced at $260,490, well above the $159,420 that Tesla sold it for earlier this year.

To those who do not know, the Model S Signature was a highly exclusive, limited-run farewell variant of the Model S Plaid that was produced this year to mark the end of production of both the Model S and Model X, Tesla’s two flagship vehicles.
Limited to just 250 units with invite-only sales, it serves as a collector’s item celebrating the legacy of the Model S, which helped pioneer Tesla’s electric vehicle success since its 2012 launch.
It bundles top-tier performance with bespoke cosmetic and luxury upgrades, plus Tesla’s Luxe Package. Here’s what the Model S Signature has over the typical Model S Plaid:
- Exclusive Exterior – Unique Garnet Red Paint, matching door handles, gold Tesla “T” badges upfront, gold Plaid and Signature badging at the rear.
- Premium Interior – White Alcantara upholstery with gold piping/accents, gold Plaid seat badges, Signature-marked door sills, individually numbered dashboard plaque, gold puddle lights, special interior lighting sequence, and a custom Signature key fob.
- Performance Upgrades – Carbon-ceramic brakes with gold calipers
- Bundled Luxe Package – Full Self-Driving (Supervised), four years of Premium Connectivity, free lifetime Supercharging
- Performance Metrics – ~1,020 horsepower, sub-2-second 0-60 MPH, ~390-mile range
Tesla quickly introduced a No Resale Agreement for the Signature Editions of the Model S and Model X, which would penalize the seller for “the amount of $50,000 or the value received as consideration for the sale or transfer, whichever is greater.”
The company continues:
“If you sell or otherwise transfer the ownership of your Model S or Model X, the remainder of the Recommended Maintenance, Wheel and Tire Protection Plan, and Windshield Protection Plan will transfer automatically to the buyer. The Full Self-Driving (Supervised), Free Supercharging and Premium Connectivity will not transfer with the vehicle and will terminate once the ownership of the Model S or Model X is transferred.”
Tesla will likely come after the seller, especially as it has been about two months since Tesla launched deliveries.
Tesla rolled out Full Self-Driving (Supervised) v14.3.5 yesterday, and about fifty miles of driving on the new version has given me enough time to highlight what seems to be strong about the release and what is not.
Additionally, Tesla has added a few new features with this specific update, which we’ll highlight as well.
Tesla Full Self-Driving v14.3.5 Performance
The new update is business as usual. Things seem to be running completely normal and necessary, but there are a few things that we’ve seemed to pick up on based on our own experience with v14.3.5, as well as what other users are seeing.
Initially, it seems to be more aware of its surroundings, making moves that are incredibly courteous to other drives and operating just a tad more reserved than what the suite might have done previously.
We had two instances where it showed this, the first being FSD needing to pass a Flagger Force vehicle that was placing down signage for the day. Their work truck was right at the front corner of a right-hand turn; typically where most cars travel when they take that turn.
FSD v14.3.5 recognized this, slowed down, and took the turn wide with no issues:

Additionally, v14.3.5 backed up for a semi truck that was making a wide turn onto a road my car was on. This is not new, but it seemed to be backing up for courtesy; it didn’t seem completely necessary, but it might have put some peace of mind in the truck driver’s head:

X user Mike P, also a Pennsylvania native like myself, shared three clips of his Tesla running v14.3.5 performing similar maneuvers. He said:
“FSD turns right into a small alley that only fits one car at a time, sees oncoming car, reverses out of alley to make space, realizes oncoming car is actually parking, re-enters alley.”

It seems like Speed Profiles are still in need of some tweaking; I am adjusting what Speed Profile I’m in frequently, constantly changing it to get it to travel at the correct speed. This was an issue for me on v14.3.4. It seems like they’re just a little inconsistent.
Terrible Parking
Parking attempts on v14.3.5 were not good. There are quite a few people who have said this:
Yeah it seems like FSD v14.3.5 is having some issues with parking early on https://t.co/Bw5ULfVmDq pic.twitter.com/RHdpjOEpIo

David Moss, the Tesla owner who has taken multiple coast-to-coast drives without any interventions, also has had some issues with parking early on with v14.3.5:

New Features
Tesla has added the ability to open Camera Preview at any time. Previously, it was only available in Park. Here’s what that feature looks like in action:
