Tesla Energy is becoming the company’s highest margin business: Elon Musk
Tesla Energy turned out to be the dark horse of the company’s third-quarter results. CEO Elon Musk even noted during the Q3 2023 earnings call that Tesla’s battery storage business is becoming one of the company’s most profitable divisions.
The Q3 2023 Update Letter revealed that Tesla’s battery storage deployments increased by 90% year-over-year to 4.0 GWh. This represented the highest quarterly deployment of battery storage systems to date. Tesla noted that this growth was made possible in no small part due to the ramp of the Megafactory in Lathrop, California. The facility produces the Megapack battery.
This milestone was reiterated by Musk during the Q3 2023 earnings call. During his opening remarks, the CEO specifically pointed out that Tesla Energy is a part of the company’s business that is steadily showing more and more strength — so much so that it is becoming Tesla’s highest-margin business.
“Regarding energy storage, we deployed 4 GWh of energy storage products in Q3. And as this business grows, the Energy division is becoming our highest-margin business. Energy and service now contribute over half a billion to quarterly profit,” Musk said.
While Musk has shown a tendency to become overly optimistic about initiatives like Full Self Driving and Autopilot, his comments about Tesla Energy becoming a high-margin business make perfect sense. Tesla’s Energy Storage devices, after all, are far simpler to design and produce than the company’s electric vehicles. Thus, they are likely easier to ramp.
Tesla CFO Vaibhav Taneja provided additional insights about the growth of Tesla Energy during the third quarter. He mentioned that the business’ growth is largely due to the Megapack’s ramp. Such statements make sense considering the constant stream of Megapacks being spotted during drone flyovers of the Lathrop Megafactory.
“Our other businesses are becoming more prominent on a stand-alone basis, with the Energy business leading the charge primarily from the growth in Megapack deployments. Our services and other businesses, on a year-on-year basis, also continued to show positive momentum as we benefit from our growing fleet,” Taneja said.

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.

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.
