Battery Pack to Have Huge Influence on Model 3 Design

Tesla Model 3 Rendition

The Model 3 is garnering more attention these days, as the Model X hits its stride on the streets of California—looking good I might say—and a probable release date in early Fall. Next up is Model 3 discussion and most of it centers around possible battery sizes.

A recent article via Seeking Alpha speculated on this very topic and predicted three different battery variations for the mass market Model 3 electric car: 43.9 kWh, 65.7 and another performance-based 65.7. Respectively, the author estimates 220, 320 and 330-mile battery range for the Model 3 in rear and all-wheel drive formats.

Carlson is right on the versions. Musk said recently at the annual shareholders meeting that “the standard version of the car (model 3) would have a single motor but we would offer a dual-motor as an option.”

Some comments from Carlson’s post suggest that Tesla’s lack of an alpha design prototype at this stage is worrisome. However, Randy Carlson mentions that upgrades in cell chemistry upgrades and battery pack configuration are the key considerations at this point in the Model 3 design.

My guess, and it is exactly that, a guess, is that Tesla is looking at what battery performance they will get from Panasonic and their GigaFactory. Small changes in the Wh/kg of the battery impact the optimum size of the motors, brakes, suspension, even the structure of the car itself. Until battery performance is locked down, any design they make rests, in a sense, on quicksand.

Carlson also talks about the advantages of using the 20700 form factor battery cells “that are more compact and would remove battery modules from the front and back foot wells.” According to Carlson, Tesla designers could lower the floor by four inches and increase aerodynamics for the Model 3. Recent comments by Musk and JB Straubel suggest that 220 miles is the goal for the Model 3 base model.

Regular car buyers have fallen in love with all-wheel drive vehicles so it begs the question whether Musk and company can produce an inexpensive base version in this format?

Tesla once offered a 40 kWh version of the Model S, but discontinued the model due to low demand. Could the same happen for a base version of the Model 3 and its single motor design? I doubt it due to the higher initial battery costs as the Gigafactory opens and with Model 3 production slated for 2017 (late) and 2018. (Freudian slip regarding Model 3 release date recently, eh?).

So it comes down Gigafactory cell buildout in the coming months and hopefully it dovetails nicely with the Model 3 design. According to Musk and Straubel, the Gigafactory is proceeding smoothly, so spring 2016 should be an exciting time for Model 3 speculation.

Avatar director James Cameron has stated that he can still agree with Elon Musk on space exploration and AI safety despite their stark political differences. 

In an interview with Puck’s The Town podcast, the liberal director praised Musk’s SpaceX achievements and said higher priorities must unite them, such as space travel and artificial intelligence. Musk responded with some positive words for the director on X.

A longtime mutual respect

Cameron and Musk have bonded over technology for years. As far back as 2011, Cameron told NBC News that “Elon is making very strong strides. I think he’s the likeliest person to step into the shoes of the shuttle program and actually provide human access to low Earth orbit. So… go, Elon.” Cameron was right, as SpaceX would go on to become the dominant force in spaceflight over the years. 

Even after Musk’s embrace of conservative politics and his roles as senior advisor and former DOGE head, Cameron refused to cancel his relationship with the CEO. “I can separate a person and their politics from the things that they want to accomplish if they’re aligned with what I think are good goals,” Cameron said. Musk appreciated the director’s comments, stating that “Jim understands physics, which is rare in Hollywood.”

Shared AI warnings

Both men have stated that artificial intelligence could be an existential threat to humanity, though Musk has noted that Tesla’s products such as Optimus could usher in an era of sustainable abundance. Musk recently predicted that money and jobs could become irrelevant with advancing AI, while Cameron warned of a deeper crisis, as noted in a Fox News report.

“Because the overall risk of AI in general… is that we lose purpose as people. We lose jobs. We lose a sense of, ‘Well, what are we here for?’” Cameron said. “We are these flawed biological machines, and a computer can be theoretically more precise, more correct, faster, all of those things. And that’s going to be a threshold existential issue.”

He concluded: “I just think it’s important for us as a human civilization to prioritize. We’ve got to make this Earth our spaceship. That’s really what we need to be thinking.”

Blue Origin has revealed plans to develop New Glenn 9×4, a “super heavy” rocket designed to deliver 70 metric tons to low-Earth orbit and directly compete with SpaceX’s Starship. 

The announcement followed the company’s successful NG-2 launch on November 13, which deployed NASA’s ESCAPADE (Escape and Plasma Acceleration Dynamics Explorers) Mars mission and landed the first stage.

Upgraded engines and reusability

As noted in a Universe Today report, Blue Origin will roll out upgraded BE-4 engines producing 640,000 lbf each, up from 550,000 lbf, starting with NG-3. This should boost the New Glenn rocket’s total first-stage thrust to 4.5 million pounds. Upper-stage BE-3U engines are expected to improve from 320,000 lbf to 400,000 lbf over the next few flights as well.

“These enhancements will immediately benefit customers already manifested on New Glenn to fly to destinations including low-Earth orbit, the Moon, and beyond. Additional vehicle upgrades include a reusable fairing to support increased flight rates, an updated lower-cost tank design, and a higher-performing and reusable thermal protection system to improve turnaround time,” Blue Origin noted. 

New Glenn “Super Heavy” 9×4

The super-heavy New Glenn 9×4, with nine BE-4s on the booster, four BE-3Us on the upper stage, will feature an 8.7-meter payload fairing. Blue Origin expects New Glenn 9×4 to be capable of transporting 70 metric tons to LEO, 14 tons to GSO, and 20 tons to trans-lunar injection, as noted by the company in a blog post. This is very impressive, as New Glenn 9×4’s capacity exceeds Falcon Heavy, SpaceX’s largest rocket available to consumers today. Falcon Heavy is capable of carrying up to 64 metric tons to low Earth orbit in a fully expendable configuration.

That being said, SpaceX’s Starship’s capacity is extremely impressive. As per SpaceX, Starship is designed to be capable of carrying up to 100-150 metric tonnes to orbit in its fully reusable configuration. At its expendable configuration, Starship’s capacity enters unheard-of territory, with SpaceX stating that the vehicle could transport 250 metric tonnes of cargo.

Tesla has secured approval for FSD testing in an urban environment in Sweden. As per recent reports from the Tesla community, Nacka, Sweden, a municipality just a few miles from Stockholm, has given its approval for FSD tests. 

A look at the municipality’s note regarding FSD’s approval, however, reveals something quite aggravating. 

FSD testing approval secured

As per Tesla watcher and longtime shareholder Alexander Kristensen, Nacka is governed by the Moderate Party. The shareholder also shared the municipality’s protocol notes regarding approval for FSD’s tests. 

“It is good that Nacka can be a place for test-driving self-driving cars. This is future technology that can both facilitate mobility and make transportation cheaper and more environmentally friendly,” the note read. 

The update was received positively by the Tesla community on social media, as it suggests that the electric vehicle maker is making some legitimate headway in releasing FSD into the region. Sweden has been particularly challenging as well, so securing approval in Nacka is a notable milestone for the company’s efforts.

Aggravating details

A look at the notes from Nacka shows that FSD’s proposed tests still met some opposition from some officials. But while some critics might typically point to safety issues as their reasons for rejecting FSD, those who opposed the system in Nacka openly cited Tesla’s conflict with trade union IF Metall in their arguments. Fortunately, Nacka officials ultimately decided in Tesla’s favor as the company’s issues with the country’s unions are a completely different matter.

“The left-wing opposition (S, Nackalistan, MP and V) voted no to this, referring to the fact that the applicant company Tesla is involved in a labor market conflict and does not want to sign a collective agreement. We believe that this is not an acceptable reason for the municipality to use its authority to interfere in a labor law conflict.

“Signing a collective agreement is not an obligation, and the company has not committed any crime. The municipality should contribute to technological development and progress, not work against the future,” the note read.
