Tesla’s battery supply constraint is ending, price parity with gas cars is at hand
Tesla’s Semi is coming, and it will be here sooner than expected. But the production of the vehicle could be pointing to one thing: Tesla is no longer battery constrained.
Past the face value portion of the story, something much bigger is happening. While the Semi entering a “volume production” phase is big news, the development of the commercial vehicle comes at a time where battery production for Tesla seems to be the main focus of the electric automaker.
In Q3 2019, CEO Elon Musk indicated that a shortage of battery cells primarily drove the Semi’s delay. If Tesla wanted to start producing the Semi, the company would have to make cells available for it. That would mean one thing: cutting back on cells utilized for Tesla’s mass-market vehicles, which at the time was the Model 3.
Building the Semi before a sufficient battery production and supply chain was established would have been detrimental to the company’s long-term plans. Of course, the Model 3 has been Tesla’s most popular vehicle since it started deliveries in 2017. Its affordability has helped Tesla reach a new market, which was all apart of Elon’s original Master Plan.
With the Model Y now being produced in Fremont, Tesla now has two mass-market vehicles that are affordable by a vast segment of the population. Ultimately, this means that Tesla needed to levy a majority of its available lithium-ion cells for the Model 3 and Model Y. Unfortunately, the Semi just was not a priority over those two cars. Why would it be? The Model 3 (and Model Y now) are Tesla’s two top sellers. Therefore, the battery needs pointed toward the 3 and the Y, with Semi production being dependent on the availability of battery cells.
If we think about Musk’s statement from Q3, he indicated that the Semi production would be based on when Tesla could manufacture the appropriate amount of lithium-ion batteries to power the Class 8 vehicle. Although demand for the 3 and the Y continues to increase, so is Tesla’s production rate, and it could be indicative that the Silicon Valley-based electric car maker is pumping out enough batteries to produce all of its vehicles without any worries of possible cell shortages.
Ultimately, this idea could lead to another significant development in the EV world as a whole, and that is price parity.
For a long time, analysts have pinpointed the electric vehicle movement’s price parity at $100/kWh for battery cell production. This means that when cells are produced at a high enough rate, batteries will be lower in cost. Then, electric cars will be the same price as gas-powered machines, making the argument of “EVs are too expensive” obsolete.
The Tesla Model 3 Performance utilizes a 75 kWh battery pack. If battery production is at $120/kWh, this would mean that the Model 3 Performance’s battery pack costs $9,000 to produce. The car’s $54,990 price tag, hypothetically at $120 per kWh, is made up of a battery pack that costs about $9,000.
If Tesla could produce batteries at a high enough rate where the cost per kWh could come down to $100, the battery pack would only cost $7,500 to build, meaning an additional $1,500 comes off the price of the vehicle altogether. Tesla’s goal is to produce enough battery cells to justify this pricing point for its cars. Also, $100/kWh is just the price parity point, and not where the cost will ultimately end up. If demand continues to increase and battery cell production keeps growing, the cost could get even lower.
If Tesla has enough batteries to justify producing mass quantities of the Model 3 and Model Y, along with the sizable battery packs of the Semi, parity could be coming sooner than expected. Most analysts indicated 2023 as the year when battery production would be on a level where EV prices could compete with their petrol-powered counterparts.
However, if the Semi is ready for a production run now, Tesla may have enough cells to introduce a more affordable pricing model for its vehicles. This could, in turn, lead to even higher production numbers, increased demand, and a sharp increase in the company’s delivery numbers.
The announcement of the Tesla Semi meant much more than the company producing its commercial vehicle. It means batteries are no longer in restricted amounts, the technology is improving, and the prices of the company’s vehicles could be coming down soon. With this, it appears that Elon Musk’s endgame with his Master Plan may be getting closer to reality.
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.

The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
