Model 3 outside Gigafactory

At the press conference held in the lobby of the Gigafactory on Wednesday evening, Elon Musk and JB Straubel told the press a great deal about the upcoming Model 3 and the company’s new focus on solar power.

On The Model 3

Musk: “I believe we are on track to meet the half million by 2018. The hardest thing to predict is really the ramp. The ramp looks like an S curve and grows exponentially. Initially the ramp looks really tiny and as you eliminate bottle necks you climb the ramp and you level off. Its always difficult for us to forecast the exact shape of the S curve for the production ramp.

“It’s much easier for us to forecast when things are going to be steady state. So we’ve been pretty good about forecasting 2018, whereas 2017 is much more in the air because we’ll be working through a complex production ramp.”

Straubel: “One of the points is the schedule and ramp up plan for the Gigafactory. With the pull up of the Model 3, and the volume goal to meet a half million cars by 2018, we also have had to pull up the Gigafactory schedule to supply the cells and battery packs for the Model 3.

“What that means is for the earlier schedule for the Gigafactory, we’ve had to pull that ahead by two years. By 2018 we have to be at 35 gigawatt hours of production to support those Model 3s. You can see the evidence of that around the factory. And Panasonic has done their part to absolutely stay in sync with that as we’ve accelerated the schedule for Model 3.”

On The Size Of The Gigafactory

Musk: “What you’re seeing is only 14% of the size of the factory overall. It’s quite huge. One of the things we discovered as we got more into the Gigafactory design and optimizing what it could do, we thought we could probably achieve about three times the output that was originally planned.

“So we originally expected to make about 35 gigawatt hours at the cell level and about 50 gigawatt hours at the module or pack level. Now we are expecting to do about 150 gigawatt hours in the same volumetric space as the original design.  We can expect to see 10,000 [workers], compared to the 5,000 or 6,000 previous estimate. Maybe in three to four years.

“Things are on track to be able to meet the Model 3 plan next year. We’re really excited about what’s happening here.”

Powerwall and Powerpack business

Musk: “Stationary storage will be as big as the car business long term. The growth rate will probably be several times what it is for the car business. We roughly assume that it’ll be probably a third of our output. But the growth rate is faster, so then grow to probably match what it is for cars.

Solar Power And  The Utility Grids

A battle is being waged between alternative power solutions and traditional utility companies. SolarCity has recently shut down operations in Nevada, putting 500 people out of work because policies instituted by the Nevada PUC the company feels are unfavorable to rooftop solar. At the press conference Wednesday, Musk made several remarks about the solar power industry and traditional power generation. He was careful to acknowledge alternative energy can cause strains for traditional utilities and grid operators.

Musk: “Solar power production actually helps the grid to a certain point. Only past a certain point does it create issues with the grid. A utility can handle up to 20% of production from solar and that helps the grid because it produces electricity when needed. Solar power peaks in the middle of the day and that’s also when air conditioning is running and businesses are operating, so power production matches usage.

“But once you exceed the 20% level, then it does become more difficult for utilities to power balance the grid. So I think it makes sense for net metering to be there up through the point where it helps the cost structure of the grid. That’s the logical thing. The utilities in some cases have tried to obfuscate that its actually helpful, and have tried to lower that number of 20% to like 3%.

Tesla And Grid Services

Musk: “I think we’ll get into grid services eventually. The goal of Tesla is to accelerate sustainable energy, so we’re going to take a step back and think about what’s most likely to achieve that goal.

Autopilot

Sandwiched into the discussion was a question about whether Musk has any regrets about how Tesla introduced its Autopilot system, especially after Consumer Reports issued a call for the company to disable the Autosteer function recently.

Musk: “No, I think we did the right thing. I think we improved people’s safety, not just in fatalities but also injuries. We can see how it actually reduces impact velocity. It can reduce impact from 76 miles per hour to 46 miles an hour. That’s massive.

“We polled Tesla owners, do you want autopilot disabled or not. Not one person wanted it disabled. That’s pretty telling.”

Tesla patent aims to improve common on-road complaint

Published

Tesla is continuing to push the boundaries of vehicle dynamics, as its latest published patent, US12654505B2, or “Suspension Actuator System for a Vehicle,’ which has finally been pushed through.

The design, which is credited to inventors Brian Lee Doorlag, Avraham Kagan, and Justin Sill, introduces a sophisticated hybrid suspension design that blends active motor-driven control with strategic passive elements to deliver superior ride quality, energy efficiency, and resilience against road imperfections, especially potholes.

At the heart of the system is an active control element powered by an electric motor. This motor drives a belt connected to a ball nut assembly and threaded screw, which adjusts the effective length of the suspension strut in real time.

By extending or retracting, the actuator can lift or lower the wheel more accurately, which can end up countering road disturbances. Sensors, including accelerometers and wheel position monitors, feed data to a suspension control system that processes inputs and commands the motor instantly.

This active component doesn’t work alone. A low-rate air spring mounts in parallel with the actuator. Its primary role is to offset much of the vehicle’s static weight, dramatically reducing the power demand on the motor.

Without this, the active system would constantly fight gravity, draining energy and generating heat. The air spring handles steady-state loads efficiently, allowing the motor to focus on dynamic adjustments.

Complementing this is a series of passive control elementsa spring and an adaptive damper—placed between the actuator and the wheel. This setup filters high-frequency vibrations before they reach the active motor, preventing it from overworking on minor inputs. The adaptive damper, potentially magnetorheological or valve-controlled, further tunes damping electronically for optimal comfort and stability.

How It Differs from Traditional Suspensions

Traditional passive suspensions compromise between comfort and handling, while pure active systems can be power-hungry and complex. Tesla’s hybrid approach resolves this by delegating tasks: the parallel air spring manages weight and low-frequency body motions, the series elements absorb rapid vibrations, and the active actuator tackles larger, lower-frequency events.

The result is a smoother, more isolated cabin experience. High-frequency road noise and harshness diminish, while the vehicle maintains precise control during cornering or acceleration. Energy efficiency improves, too—lower motor loads mean reduced battery drain, potentially extending range in electric vehicles.

How It Mitigates Potholes Specifically

Potholes are a major challenge because they provide a sudden drop to the wheel plunge, jarring the body of the vehicle, risking damage. The patent explicitly addresses this. Upon detecting a pothole (via sensors or predictive mapping), the control system activates

the motor to retract the strut, effectively pulling the wheel upward to minimize downward excursion. The series spring/damper cushions the impact, while the parallel air spring maintains overall support.

This proactive “wheel retraction” prevents sharp jolts, preserving passenger comfort and protecting components. Integrated with Tesla’s road roughness mapping patents, the system could anticipate potholes from fleet data, enabling preemptive adjustments for even smoother navigation.

Future Implications for Tesla Vehicles

This technology builds on Tesla’s existing adaptive dampers and air suspension that is seen in Cybertruck, but advances toward fully active control. It could roll out to future models, including refreshed Cybertrucks or next-gen vehicles, enhancing both daily drivability and off-road capability. By minimizing power use and complexity, it aligns with Tesla’s goals of efficiency and scalability.

In summary, US12654505B2 exemplifies Tesla’s engineering philosophy: intelligent integration over brute force. This hybrid suspension promises quieter, more comfortable rides and robust pothole defense, potentially setting a new standard for automotive comfort. As Tesla iterates, drivers can look forward to roads feeling far less rough.

The Tesla Cybercab got a huge nod of support from a Texas Department of Transportation official, who said the all-electric ride-hailing vehicle is “a tangible example of how quickly our transportation system is evolving.”

The Cybercab was present at the Texas Department of Transportation’s Texas Innovation Invitational, an event held each year that allows innovative companies to showcase advancements in transportation.

Tesla Cybercab specs revealed: range, curb weight, range ratings, and more

Marc Williams, the Texas Department of Transportation’s Executive Director, sat in a Cybercab and shared his thoughts in an extensive post on LinkedIn.

Williams’s comments show how Tesla, with its Cybercab, is leading the charge of passenger travel and how it’s changing so rapidly. He notes the absence of traditional driving controls as a telltale sign that the Cybercab is a catalyst for major automotive change, taking controls from drivers and turning them into full-time passengers.

“Observing this vehicle firsthand–from its design and butterfly doors to the cargo trunk configuration–provides a tangible example of how quickly our transportation system is evolving. Sitting inside the cabin, the complete absence of traditional driver controls underscores a significant shift in mobility and vehicle design. No steering wheel, no accelerator, no brake. Only a single touchscreen monitor.”

Tesla has had a great relationship with the State of Texas, especially with its Robotaxi ambitions. Currently, Texas has Tesla Robotaxi operating in multiple cities: Dallas, Austin, San Antonio, and Houston. The company’s main manufacturing plant is also located just outside Austin, and Tesla moved its headquarters to the state several years ago.

The Cybercab is a purpose-built, fully autonomous, two-passenger Robotaxi vehicle designed specifically for ride-hailing services. Tesla has said for years it would be built without a steering wheel or pedals present, although there is still quite a bit of debate among the community regarding that potential.

Earlier this week, we received official word that the EPA had provided the Cybercab with a Certificate of Conformity, giving Tesla permission to enter the vehicle into the chain of public commerce. It is officially ready for roads.

The big question for Tesla remains: Can it solve self-driving before the steering-wheel-less Cybercab officially enters production?

The Boring Company just doubled its tunneling power in Nashville

The Boring Company’s Prufrock MB2 is commissioned and ready to mine beneath Nashville’s streets.

The Boring Company’s second tunnel boring machine, Prufrock MB2, is officially ready to dig in Nashville. The company confirmed the news on X, posting: “Prufrock-MB2 is ready to mine in Nashville! MB2 commissioning is complete, including the brief 11 rpm rotation shown here. Will MB2 catch up to MB1, who had quite the head start? And Prufrock-MB3 ships in August!”

MB2 arrives with meaningful improvements over its predecessor. Lessons learned from the launch and operation of MB1 have already been applied to MB2 to improve efficiency and prepare the machine for launch.

Traditional tunnel boring machines operate in a stop-and-go cycle, digging roughly five feet, halt, erect precast concrete segments to line the tunnel wall, then resume. That repeated interruption is one of the main reasons conventional tunneling is slow and expensive. Prufrock is designed to install the tunnel liner simultaneously with mining, eliminating the need to stop every five feet. The machine also skips the need for excavated launch pits. Prufrock arrives on a truck, tilts down, and launches into the ground within 24 hours. And when the tunnel is complete, it emerges from the ground and drives to its next launch site on a trailer, eliminating the need for expensive cranes or pit excavation. The machine is also fully electric and runs with zero people in the tunnel during normal operations, controlled remotely from a surface operations center.

It won’t be long before we hear of another major update on The Boring Company’s Music City Loop project – a planned underground transit network beneath Nashville that would move passengers in electric vehicles through a series of tunnels at highway speeds, and bypassing surface traffic entirely. Nashville was selected in part because of its strong rock conditions that suits the Prufrock machines well, and relatively less regulatory hurdles.

Progress has been steady on multiple fronts. All 37 permits and approvals required ahead of tunneling have been obtained, out of 45 total. Key wins include a fully executed TDOT tunnel permit authorizing 25 miles of tunnel, unanimous airport authority approval for a Nashville International Airport station, and the city’s first residential station agreement serving downtown tower residents.

With MB1 already tunneling, MB2 now commissioned, and MB3 shipping in August, Nashville is becoming something of a live proving ground for scaled tunnel boring. The broader ambition is not limited to one city. The Boring Company’s stated goal is to make underground transportation a practical alternative to surface roads across major metro areas. Nashville is one of many cities, including a successful Las Vegas tunnel system, where that idea is being put to the test at real speed.
