Tesla Model Y manufacturing improvements highlighted in published patent application
In an effort to continue streamlining its manufacturing process, Tesla has developed a new vehicle frame casting machine. The specifics are described in a patent application published on July 18, 2019 titled, “Multi-Directional Unibody Casting Machine for a Vehicle Frame and Associated Methods.” CEO Elon Musk previously referred to such a machine that was under development during his conversation with Ryan McCaffrey of the Ride the Lightning podcast in June. His comments at the time were in reference to manufacturing improvements being made specifically for Model Y production.
“There are some manufacturing improvements for the [Model] Y. The rear underbody we’re moving to an aluminum…casting instead of a series of stamped steel and aluminum pieces,” Musk revealed in the interview. “When we get the big casting machine, it’ll go from 70 parts to 1 with a significant reduction in capital expenditure on all the robots to put those parts together.”

As described, Tesla’s new casting machine will have a central hub to receive several dies that are assembled into specific portions of a vehicle frame before being cast. The dies can transform into multiple configurations along the X, Y, and Z axis, essentially forming into numerous part molds. Further suggested by the patent application is that a full car frame may be made with a single cast using these transforming capabilities.
Casting molds are common in car manufacturing; however, single part molds are often what’s used, and bolts and welding are then subsequently required. A single casting machine configurable for several parts has many advantages, including reduced build time, operation costs, manufacturing costs, factory footprint, tooling costs, and equipment quantity. Using a casting machine for the Model Y will also reduce the weight of the all-electric crossover, according to Musk. Battery efficiency will be positively impacted by a lighter vehicle with only an 8-10% impact on range expected in the Model Y when compared to the Model 3.
Anticipation for the Model Y is building despite few details being revealed by Tesla since its unveiling in March. During the California-based car maker’s annual shareholder meeting this year, a red working prototype of the vehicle was on display alongside a next generation Roadster and a Tesla Semi, both also red. Prior to the event, only blue and white versions had been revealed, the blue having been used for test drives at its unveiling.
The manufacturing location for the Model Y also has yet to be announced, although Tesla’s Fremont factory looks to be the most likely candidate. Production is still anticipated for 2020.
Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes

The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
-
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.

Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
Sweden’s IF Metall union has announced that it is ending all protests against Tesla, effective immediately.
The union said in a statement this morning:
“There seems to be no limits to the length Tesla would go to keep unions out of their operations. Unfortunately, they have managed to pay their way out in Sweden. At least that has given the former IF Metall members more money in their pocket, but the insecurity of not having a union or a collective agreement still remains.”
IF Metall has been after Tesla in Sweden for the past three years, attempting to push unionized operations into its factories. Tesla, on the other hand, has given its employees the chance to unionize in various markets. However, the organization says that Tesla has “bought out all of its striking members.”

“Today, we end our industrial action against Tesla. We do so because it can no longer have an effect – not because our principles have changed,” a written statement said.
Over the past three years, IF Metall has definitely been a thorn in the side of Tesla and its operations in Sweden. The primary strike started in October 2023, when IF Metall members at Tesla’s Swedish Service Centers refused to work.

Strikes extended to blockades and work stoppages at non-Tesla-owned repair shops that service Teslas. This limited and stopped anything related to warranties, transport damage, and other work on Teslas ending, eliminating work arounds for customers.
Sympathy strikes followed, as postal workers, dock workers, electricians, and other tradesmen stopped working. Add in lawsuits and other pressures, and you get the full scope of what strategies the union has used against Tesla over the past several years.
But now, it’s all over.
“We will continue to defend the right of workers to organize. We will continue to fight for collective bargaining. And we will continue to stand in solidarity with workers and trade unions facing similar challenges elsewhere – just as you have stood with us,” IF Metall said.
