Tesla has released a very detailed update on its 4680 battery cell program, which is expected to be critical for its future electric vehicles.
The 4680 battery cell format has taken the industry by storm since Tesla unveiled its own cell strategy at Battery Day in 2020.
The automaker claimed a potential to reduce battery cost by over 50% with the new design; it has been trying to bring it to volume production since, but it has run into some bottlenecks.
In a conference call following the release of its Q1 2023 financial results, Tesla gave a detailed update about its 4680 battery cell production.
Drew Baglino, Tesla’s senior VP of engineering, said about the 4680 cell:
On Battery Day, we established a cost-down roadmap through 2026 across five areas of effort. There was the cell design we discussed; anode and cathode materials, the structural pack concept, and the cell factory itself. We’ve been making progress across all these aspects since then. For the Cell Factory, for the Texas 4680 factory, we are part way through building and commissioning and installing and operating, will be 70% lower capex per gigawatt hour than typical cell factories when fully ramped in line with what we described on Battery Day. And we’re continuing to further pursue densification and investment reduction opportunities in future factory buildouts like in Nevada.
Tesla is producing 4680 cells at its pilot plant in Fremont, but it is expected to reach higher volume production at Gigafactory Texas, which is the “cell factory” Baglino is talking about here.
He continued:
On the cell design, we’re in production with not only the first generation tabless cell we unveiled on Battery Day but a second more manufacturable version in Texas today. On the cathode material side. we have a number of activities underway per the Battery Day roadmap. For lithium, our Corpus Christi Lithium Refinery breaks ground this May. Our goal is to start commissioning portions of the facility for the end of the year. The refinery uses the sulfate-free refining process with reduced process costs, no acid or caustic reagents, lower embodied energy. It actually produces a beneficial byproduct that can be re-purposed in construction materials.
The executive also gave a more specific update on its Cathode factory at Gigafactory Texas:
We discussed all of these concepts on Battery Day. Same with cathode precursor, we’ve successfully demonstrated a lower process cost, zero waste water precursor process that we described on Battery Day at both lab and pilot scale and are on the detailed design phase for incorporating this technology into the front end of our Austin cathode facility. On cathode production, we are 50% equipment and 75% utilities installed at our new cathode building in Austin with our goal to begin dry and wet commissioning this quarter and next quarter with a target to produce first material before the end of the year.
The 4680 cell also enables Tesla’s new structural battery pack design. The Model Y in production at Gigafactory Texas is the first one to feature this radically different chassis/battery pack design, but Tesla’s future vehicles, including the upcoming Cybertuck, are expected to feature this design.
Baglino gave an update on that front:
Structural pack, we saw big improvements with pack manufacturing with the 4680 cell on the structural pack concept, 50% lower capex and 66% smaller factory with the same output in gigawatt hours per year. We do believe structural as a concept is a good one. It’s simpler. We’ll continue to structurally load the cells and use the pack as the floor of the vehicle while iterating the design to closer to B-level execution of this A-level architecture in future programs. And zooming out for the 4680 team Q1 was all about cost and quality.
The executive shared some details about improvements in production output this quarter and focus on reducing costs going forward in preparation for Cybertruck volume production:
We made significant improvements in both areas. On Texas production, we increased 50% quarter-over-quarter, through yields increased 12% and peak rate increased by 20% and through yields improved by 20%. Altogether, the team accomplished a 25% reduction in COGS over the quarter and we are on track to achieve steady-state cost targets over the next 12 months. And going forward for the rest of the year, the priority one is to yield in cost for the 4680 program as we steadily ramp production ahead of Cybertruck next year.
This is the most detailed update on Tesla’s 4680 battery program and could indicate that Tesla is starting to get out of the woods.
That network of dependable high-speed chargers, paired with solid app integration that makes it easy for Tesla drivers to find available chargers just about anywhere in the US, gave the brand a leg up – but no more. By opening up the Supercharger network to brands like Ford, Hyundai, Kia, and others, Tesla has given away its biggest competitive advantage.
Add in charging and route-planning apps like Chargeway, that make navigating the transition from CCS to NACS easier than ever with its intuitive colors and numbers and easy on/off switch for vehicles equipped with NACS adapters, and it feels like the time is right to start suggesting alternatives to the old EV industry stalwarts. As such, that’s exactly what I’m going to do.
Here, then, are my picks for the best Tesla S3XY (and Cybertruck) alternatives you can buy.
Less Model S, more Lucid Air

Developed by OG Tesla Model S engineers with tunes from Annie Get Your Gun playing continuously in their heads, the Lucid Air promises to be the car Tesla should and could have built, if only Elon had listened to the engineers.
With panel fit, material finish, and overall build quality that’s at least as good as anything else in the automotive space, the Lucid Air is a compelling alternative to the Model S at every price level – and I, for one, would take a “too f@#king fast” Lucid Air Sapphire over an “as seen on TV” Model S Plaid any day of the week. And, with Supercharger access reportedly coming later this quarter, Air buyers will have every advantage the Supercharger Network can provide.

Less Model 3, more Hyundai IONIQ 6

Hyundai has been absolutely killing it these days, with EVs driving record sales and new models earning rave reviews from the automotive press. Even in that company the IONIQ 6 stands out, with up to 338 miles of EPA-rated range and lickety-quick 350 kW charging available to make road tripping easy – especially now that the aerodynamically efficient IONIQ 6 has Supercharger access through a NACS adapter (the 2026 “facelift” models get a NACS port as standard).
Once upon a time, Mrs. Jo Borrás and I were shopping three-row SUVs and found ourselves genuinely drawn to the then-new Model X. Back then it was the only three-row EV on the market, but it wasn’t Elon’s antics or access to charging, or even the Model X’s premium pricing that squirreled the deal. It was the stupid doors.
We went with the similarly new Volvo XC90 T8 in denim blue, and followed up the big PHEV with a second, three years later, in Osmium Gray. When it’s time to replace this one, you can just about bet your house that the new 510 hp EX90 with 310 miles of all-electric range will be near the top of the shopping list.
The sporty EV6 GT made its global debut by drag racing some of the fastest ICE-powered cars of the day, including a Lamborghini, Mercedes-AMG GT, a Porsche, even a turbocharged Ferrari – and it beat the pants off ’em. Combine supercar-baiting speed with an accessible price tag, NACS accessibility, $10,000 in customer cash on remaining 2024 models ($3,000 on 2025s) and just a hint of Lancia Stratos in the styling, the EV6 is tough to beat.
If you disagree with that statement and feel like driving a new Tesla Cybertruck is the key to happiness, I’m not sure an equally ostentatious GMC Hummer EV or more subtle Rivian R1T will help you scratch that particular itch – but maybe therapy might!

There’s no question that electric construction equipment is safer, more precise, and generally better than the diesel equipment it’s replacing, but getting power to that equipment remains a logistical challenge that hasn’t been solved for. With this new mobile Megawatt charging station, however, Komatsu think they’ve found a solution — with up to 6 MW of power!
Developed by Tesla co-founder Ian Wright, Dimaag, and Japanese equipment giant Komatsu, the groundbreaking Mobile Megawatt Charging System (MWCS) promises to bring electricity where it’s needed, anywhere on the job site, then quickly dispense enough energy to get the electric machines under its care back up and running.
And, with Megawatt power delivery on tap, the new Komatsu-Dimaag MWCS can power up equipment assets between shift changes — if it even takes that long!

The MWCS boasts a compact, high-efficiency DC-DC converter and a long-life, high-discharge-rate Battery Energy Storage System (BESS) on board that can be connected to a DC fast charger itself, or get “trickle charged” between shifts. Both the battery and its control systems make use of an advanced thermal management solution that Komatsu and Dimaag say optimizes both safety and battery life during high-power delivery.
To make sure the MWCS can get all that power where it needs to, wherever it needs to, the machine is equipped with with stout, construction-grade AT tires, 4-wheel drive, and 4-wheel steering to navigate tight surroundings and rough terrains that other solutions wouldn’t be able to get to. And, while it isn’t mentioned in the press release, there’s a common sense idea here that you could, in a pinch, use the MWCS to tow less capable vehicles out of the mud and snow, if needed.
For their part, it seems like the people at Dimaag are pretty happy with the results. “Dimaag is excited to collaborate with Komatsu, introducing our advanced ESS and DC-DC architecture to revolutionize electrification in construction,” stated Ian Wright, VP Engineering at Dimaag. “Off-road vehicle electrification demands practical solutions that not only meet but exceed the performance of equivalent large diesel engine vehicles, while also providing substantial Total Cost of Ownership (TCO) savings. Dimaag’s electrification and high-power megawatt charging systems are designed to achieve this.”
The prototype MWCS shown, above, features a 295 kWh battery pack and an MCS connector delivering up to 1,500 amps and 1,000 volts of power. Komatsu envisions a scenario wherein the mobile charger makes its rounds on the job site charging up equipment and heading back to grid power (if available) to charge itself.
Conceptually similar to the mobile power platform being developed by American firm Dannar, this new mobile Megawatt charging unit has some heavy-hitting names behind it that make it impossible to ignore. Combine that with Komatsu’s ever-increasing push towards full electrification (the two machines shown, above, are all-new in the last 60 days, with more to come) and it really feels like the MWCS is going to be A Real Thing™️somewhat sooner than later.
