During Tesla’s Battery Day event, Elon Musk and Drew Baglino announced that its pilot Roadrunner cell production line would be capable of producing about 10 GWh worth of batteries per year. The facility’s output was almost spoken as an aside, with both executives simply stating its target as a given. A closer look at the Roadrunner line’s planned annual output shows that Tesla has created something that’s incredibly disruptive and innovative at the same time.  

As noted by Benchmark Mineral Intelligence, a market intelligence publisher for the lithium-ion battery to electric vehicle (EV) supply chain, the Roadrunner line’s 10 GWh output actually makes it the world’s 13th-largest battery production facility in the world. Granted, the facility is still in the process of being ramped, but once it achieves its full potential, it would be making a significant amount of batteries. Today, after all, Gigafactory Nevada’s output still stands below 40 GWh, and that’s with a monster battery factory that’s already considered as the largest in the world.

The disruption of Tesla’s next-generation battery and cell production system becomes even more evident when one considers just how compact the system is. The Roadrunner line is located in Tesla’s Kato Road facility, which is comprised of two buildings that cover 184,880 sq ft combined, as per the company’s filings to the City of Fremont. To build a 10 GWh battery production plant from such a space is something truly remarkable. 

It should also be considered that the 10 GWh Roadrunner system is a pilot production line, which means that it’s still bound to be improved over time. The Kato Road facility may hold its place as the world’s 13th-largest battery production plant when it hits its target output, but there will likely be very little that could stop Tesla from upgrading the facility even further, or at least as soon as improvements become available. Such is the culture of Tesla, after all. 

The Roadrunner line’s 10 GWh output is nothing to scoff at. Back in 2010, the entire battery production industry produced 20 GWh, as per data from the European Commission. This means that the pilot Roadrunner line has an output equal to half the world’s battery production output a decade ago. Interestingly enough, neither Elon Musk nor Drew Baglino emphasized these points during the Battery Day event. Any other carmaker would likely have highlighted such a point. 

The innovations that were announced on Battery Day have the potential to change not only the electric vehicle sector but the transportation industry as a whole. With its new battery tech, Tesla will be able to produce batteries at the terawatt level from facilities that are smaller than the completed iteration of Gigafactory Nevada, which is expected to produce 150 GWh. This is key to the company’s long-term goal, which includes producing 20 million vehicles for the global auto market by 2030.

Tesla is bringing back something it took from the Model 3…for a price

“Modify your Model 3 by replacing the turn signal buttons on your steering wheel with turn signal stalks. This modification is included in the purchase price and is installed by a Tesla Service Center.”

Tesla is bringing back the Model 3’s turn signal stalk in China after removing the part with the refresh of the all-electric sedan early last year.

However, it is going to cost you.

In 2024, Tesla launched the Model 3 “Highland,” a refreshed version of the vehicle that included several large-scale changes. One of the most noticeable was the lack of a turn signal stalk, something the company chose to remove and instead implement turn signal buttons on the steering wheel.

The buttons were met with mixed reviews, as some drivers complained that it was too difficult to get used to them. Others had no problem with the change, noting that it was slightly more convenient for them or that they enjoyed the minimalistic look.

Now, Tesla is offering Model 3 owners in China the opportunity to replace the stalk for a price of ¥ 2,499, or about $350:

“Modify your Model 3 by replacing the turn signal buttons on your steering wheel with turn signal stalks. This modification is included in the purchase price and is installed by a Tesla Service Center.”

Tesla notes on its website that the service is available for Model 3 vehicles without stalks manufactured after February 7, 2025. Any car without a stalk that was manufactured before that date will have the service available to them in the future.

Installation can be performed at a Service Center or by the owner. However, Tesla notes that it is not responsible for any damages resulting from self-installation and recommends that the part be put in by an employee.

The cockpit of the Tesla lineup has been under intense scrutiny by the company in recent years. After a few changes to things like the stalk, steering wheel shape, and others, Tesla has usually given drivers the chance to have things reverted back to their preferences if they want.

They did this for the Model S and Model X a few years ago after implementing the yoke steering wheel.

The stalk was not supposed to be removed from the Model 3 and Model Y, but Tesla chose to do so with the refresh last year.

It seems the minimalization of the cockpit, overall, is a move that prepares drivers for autonomy, as eventually, Teslas will be void of pedals, steering wheels, and any other apparatus that are used to control the car.

Tesla launches new loaner program that owners will love

Tesla is now giving owners the opportunity to rent a vehicle from them, and it includes a few very attractive features that will have you second-guessing another loaner from insurance.

Tesla has launched a new loaner program that owners will love, as it resolves some concerns over a replacement vehicle while it is being repaired.

Earlier this week, Tesla launched the option to rent a Tesla loaner vehicle for just $45 per day if your vehicle is in Collision Repair. Collision repairs did not formerly warrant the issuance of loaner vehicles, as the insurance provider of the car owner would provide transportation arrangements.

Tesla is now giving owners the opportunity to rent a vehicle from them, and it includes a few very attractive features that will have you second-guessing another loaner from insurance.

The Tesla you rent while your car is in collision repair will come with free Full Self-Driving, free Supercharging, and free toll coverage, no small print included.

All things considered, this is a great deal for those who require a car for transportation while their car is being repaired.

The cost of Supercharging and Full Self-Driving alone would warrant the $45 per day price tag. Add in the tolls for those who commute on turnpikes for work or are planning an extensive trip that would require it, and it truly becomes an even more attractive deal.

Tesla has done a good job at improving its Service division over the past few years, and it truly needed it. In hopes of launching an F1-style service experience, Tesla started doing away with some of its perks, including loaner vehicles for single-day visits and even Uber credits.

However, it has listened to the complaints of its owners and tried to cater an experience that is more advantageous and less of a hassle. It’s already made tremendous steps in the past few years, and this is the icing on the cake.

SpaceX Starship Flight 10: What to expect

SpaceX implemented hardware and operational changes aimed at improving Starship’s reliability.

SpaceX is preparing to launch the tenth test flight of its Starship vehicle as early as Sunday, August 24, with the launch window opening at 6:30 p.m. CT. 

The mission follows investigations into anomalies from earlier flights, including the loss of Starship on its ninth test and a Ship 36 static fire issue. SpaceX has since implemented hardware and operational changes aimed at improving Starship’s reliability.

Booster landing burns and flight experiments

The upcoming Starship Flight 10 will expand Super Heavy’s flight envelope with multiple landing burn trials. Following stage separation, the booster will attempt a controlled flip and boostback burn before heading to an offshore splashdown in the Gulf of America. One of the three center engines typically used for landing will be intentionally disabled, allowing engineers to evaluate whether a backup engine can complete the maneuver, according to a post from SpaceX.

The booster will also transition to a two-engine configuration for the final phase, hovering briefly above the water before shutdown and drop. These experiments are designed to simulate off-nominal scenarios and generate real-world data on performance under varying conditions, while maximizing propellant use during ascent to enable heavier payloads.

Starship upper stage reentry tests

The Starship upper stage will attempt multiple in-space objectives, including deployment of eight Starlink simulators and a planned Raptor engine relight. SpaceX will also continue testing reentry systems with several modifications. A section of thermal protection tiles has been removed to expose vulnerable areas, while new metallic tile designs, including one with active cooling, will be trialed.

Catch fittings have been installed to evaluate their thermal and structural performance, and adjustments to the tile line will address hot spots observed on Flight 6. The reentry profile is expected to push the structural limits of Starship’s rear flaps at maximum entry pressure.

SpaceX says lessons from these tests are critical to refining the next-generation Starship and Super Heavy vehicles. With Starfactory production ramping in Texas and new launch infrastructure under development in Florida, the company is pushing to hit its goal of achieving a fully reusable orbital launch system.
