Update: Lede paragraph date revised to Thursday to reflect accuracy.
Hertz gave several updates on its fleet of Tesla and Polestar all-electric vehicles, which it started offering to customers earlier this year, during its Earnings Call for Q2 2022 held on Thursday.
Hertz expanded its EV offerings to sixteen new cities earlier this month and has experienced widespread success in its EV fleet.
Initial Order of 100,000 Teslas
Hertz initially ordered 100,000 Tesla Model 3 and Model Y vehicles in October 2021. The move was Hertz’s introduction into EV adoption, which has expanded to other automakers, including Polestar, who announced a 65,000 unit deal with the rental agency just months later. The 100,000 vehicle deal was not offered at a discount. However, Hertz has maintained that its adoption of Teslas has resulted in a dramatic spike in interest from renters.
“With respect to EV specifically, over 15,000 Uber drivers to date have rented a Tesla from Hertz, at a minimum rate of $334 per week, comprising over half a million transaction days,” company CEO Stephen Scherr said. “Driver feedback has been positive and they remain drawn to the opportunity as gasoline prices remain elevated and demand for the service among Uber customers is strong. Our Tesla’s enabled Uber drivers could differentiate themselves and to improve upon the quality of their riders experience, and that translates into higher earnings for them.”
20,000 Teslas and Polestar EVs Delivered
Hertz detailed on the call that it has accepted around 20,000 electric vehicles in its fleet since it started taking deliveries of its various EVs. Scherr continued that deliveries are ongoing.
Maintenance Reductions
Electric vehicles are most often noted for their drastic reductions in service compared to combustion engine vehicles, which results in more savings over the lifespan of the car due to fewer moving parts. Hertz is learning that lesson pretty easily, according to Scherr, who stated the company is seeing a roughly 50 to 60 percent decrease in maintenance costs:
“On maintenance, I think Kenny said to you, we are running kind of 50% to 60% of what maintenance costs are on ICE vehicles. That’s roughly in line with where we are. If there’s anyone surprised, it’s probably a slightly higher expense on tires, but not much more, and that’s embedded in the figure I’m giving you. So I would say, overall, we are very pleased with the results. They’re coming in roughly in line with what we thought when we first underwrote the move in this strategic direction.”
Additionally, Kenny Cheung, Hertz’s CFO, also commented on the maintenance cost reductions:
“As for the primary drivers of the year-on-year increase, we experienced higher cost and transportation and fuel, reflecting the effect of broader inflationary trends as well as in maintenance on order fleet. We expect maintenance expenses to moderate as our fleet continues to grow younger. On the forward, we anticipate additional operating leverage as more expensive third-party labor strategically replaced with Hertz employees and we further reduced maintenance expense as we rejuvenate the fleet and continue to grow our number of EVs.”
Return Customers
Scherr said that customers seem to be more interested in renting Teslas over and over again, which has translated to an increase in repeat clients for the company. “I think we have schooled our customers on how to use them, so much so that I think there’s an embedded tether there,” he said, referring to Tesla’s key card. “They’re coming back to use the car and rent the car more frequently. And I think all of those are expressions of the first mover edge that we have around EVs.”
Consumers may be hesitant to try a new, technologically-advanced product, especially when dealing with a car. However, it seems that once Hertz’s rental clients make the jump to try an EV, they’re much more likely to come back simply because of the ease of access and features.
Less Vehicle Depreciation
Company executives also stated that the depreciation of EVs in their rental fleet is moving at a slower pace than its ICE vehicles. Cheung said that the performance of the EV fleet early on has the company “more confident” in the economics of the BEVs compared to their ICE offerings.
This is comparable to the scenario that police departments have when purchasing an EV. Initially, the cost of a quality electric vehicle is somewhat higher than an ICE vehicle. Over time, as fuel costs, maintenance, and other costs pile up, the EVs will be more advantageous to Hertz and other adoptees in the books. The cost of savings is exponentially more in an EV compared to an ICE car. This has been proven on several occasions, including with the Westport, Connecticut Police Department.

Tesla is using a redesigned Cybertruck battery cell to mitigate Semi challenges
It is perhaps the most recent example of Tesla using unique engineering prowess and cross-pollinating vehicle elements to solve common problems, something it does better than most companies out there.
Tesla revealed that it is utilizing redesigned Cybertruck battery cells in its Long Range Semi to mitigate some pertinent challenges that come with long-haul logistics.
It is perhaps the most recent example of Tesla using unique engineering prowess and cross-pollinating vehicle elements to solve common problems, something it does better than most companies out there.
Tesla’s long-awaited Semi truck is entering production at its Nevada Gigafactory, and fresh factory footage reveals a clever evolution in its battery technology.
The Long Range variant, designed for up to 500 miles of real-world range, relies on a structural battery pack that uses the same 4680-form-factor cells found in the Cybertruck.
However, Tesla engineers have completely redesigned the pack’s architecture—shifting from the flat, pancake-style modules typical in passenger vehicles to a compact, vertical cubic layout. This change isn’t just about cramming more energy into the chassis; it’s a targeted solution to one of electric trucking’s biggest headaches: range loss in cold climates.
Dan Priestley, Head of the Tesla Semi program, said:
“We’re using essentially the same cell out of Cybertruck, but our cars packs are more like a pancake. Whereas these are more like a cube. You get a lot of energy stored in a small space. You can only do this if you design the vehicle to be electric from the ground up.”
Here, in all its glory, is the exclusive first look at the massive @Tesla Semi factory.
Our @corememory crew went to Nevada to see the line come to life, as it gets ready to pump out thousands of all-electric trucks. We saw the new cab and went on a drive too. Wunderbar! pic.twitter.com/a0S5zVEr87

In conventional EVs, battery packs are laid out horizontally in wide, flat arrays to fit under the floor. While this works for cars and even the Cybertruck’s structural pack, it exposes a large surface area to the elements.
Heat escapes quickly, especially overnight when the truck is parked. Cold temperatures slow chemical reactions inside lithium-ion cells, reducing available energy and forcing the vehicle to expend extra power warming the battery and cabin.
Real-world tests on vehicles like the Cybertruck show winter range losses of 20-40 percent, depending on conditions. For long-haul truck drivers operating in Canada, Scandinavia, or the northern U.S., this “silent killer” means unplanned stops, reduced payloads, and higher operating costs.
From personal experience, cold weather still impacts EV batteries even with various inventions and strategies that companies have come up with. In the cold Pennsylvania winter, charging was much more frequent for me due to range loss due to temperatures.
Tesla’s cubic battery pack flips the script. By arranging the 4680 cells in tall, dense vertical stacks, the pack minimizes external surface area relative to its volume—essentially turning the battery into its own thermal blanket.
Factory video from the Semi assembly line shows these large, yellow-green structural modules mounted directly onto the chassis, forming a near-cube shape.
The reduced exposure helps the pack retain heat generated during operation, keeping cells closer to their optimal temperature even after hours in sub-zero conditions.
The design doesn’t stop there. Tesla pairs the cubic pack with an advanced heat pump system that actively recycles thermal energy from the motors, brakes, and even ambient air.

Unlike passive systems in earlier EVs, this architecture transfers waste heat back into the battery, maintaining readiness for morning departures without draining the pack.
Executives have noted that the combination, cubic geometry plus intelligent thermal management, dramatically cuts overnight cooldown and range degradation, making the Semi viable for 24/7 fleet operations in harsh winters.
Beyond cold-weather performance, the redesigned pack integrates structurally with the truck’s frame, enhancing rigidity while simplifying assembly. Production footage shows workers installing the massive modules early in the line, signaling that the Semi’s battery is now a core chassis component rather than an add-on.
Using proven 4680 cells keeps costs down and leverages Tesla’s scaled manufacturing know-how from Cybertruck and Model Y lines.
Tesla’s focus on ramping up Semi output will lean on small innovative steps like this one. Truckers are not immune to traveling in cold weather conditions, and changes like this one will help make them more effective while also increasing output by logistics operators who choose to go all-electric with the Tesla Semi.

SpaceX is keeping the Space Station alive again this weekend
SpaceX’s Falcon 9 launches Northrop Grumman’s Cygnus NG-24 to the ISS with 11,000 pounds of cargo Saturday.
SpaceX is targeting April 11 for the launch of Northrop Grumman’s Cygnus XL cargo spacecraft to the International Space Station, carrying over 11,000 pounds of supplies, science hardware, and equipment for the Expedition 73 crew aboard. Liftoff is set for 7:41 a.m. ET from Space Launch Complex 40 at Cape Canaveral Space Force Station, with a backup window available April 12 at 7:18 a.m. ET.
The mission, officially designated NG-24 under NASA’s Commercial Resupply Services program, names its spacecraft the S.S. Steven R. Nagel in honor of the NASA astronaut who flew four Space Shuttle missions and logged over 723 hours in space before his death in 2014. Unlike SpaceX’s own Dragon capsule, which docks autonomously, Cygnus relies on NASA astronauts to capture it using a robotic arm before it is berthed to the space station’s module for unloading. When the mission wraps up around October, the Cygnus will depart loaded with station trash and burn up on reentry.
Countdown: America is going back to the Moon and SpaceX holds the key to what comes after
This is the second flight of the Cygnus XL configuration, which debuted on NG-23 in September 2025 and offers a roughly 20% increase in cargo capacity over the previous design. Northrop Grumman switched to Falcon 9 launches after its own Antares 230+ rocket was retired in 2023 following supply chain disruptions from the war in Ukraine.
The upcoming cargo includes a new module to advance quantum research, and an investigation studying blood stem cell production in microgravity with potential therapeutic applications on Earth.
The NG-24 mission is one piece of a much larger picture for SpaceX and the U.S. government. As Teslarati reported, SpaceX has become an indispensable launch provider for U.S. national security missions, picking up a $178.5 million Space Force contract in April 2026 to launch missile tracking satellites, while also holding roughly $4 billion in NASA contracts tied to the Artemis lunar program.
At a time when no other American rocket can match the Falcon 9’s combination of reliability, cost, and launch cadence, Saturday’s mission is a straightforward reminder of how much the U.S. government now depends on a single commercial provider to keep its astronauts supplied and its satellites flying.

Tesla hits FSD hackers with surprise move
In recent weeks, the company has begun remotely disabling FSD capabilities on affected vehicles, and in some instances, permanently revoking access even for owners who paid thousands of dollars for the feature.
Tesla is cracking down on hackers who have figured out a way to utilize third-party programs to activate Full Self-Driving (FSD) in their vehicles — despite the suite not being approved for use in their country.
Tesla has launched a sweeping enforcement campaign against owners using third-party hardware hacks to activate FSD software in countries where the advanced driver-assistance system remains unregulated or unapproved.
In recent weeks, the company has begun remotely disabling FSD capabilities on affected vehicles, and in some instances, permanently revoking access even for owners who paid thousands of dollars for the feature.
Tesla has started remotely disabling Full Self-Driving on cars fitted with third-party CAN bus hacks in countries where the software is not yet approved.
This crackdown began after the hacks started spreading widely last month. 👇 pic.twitter.com/wL8VqZuTlK

Reports of the crackdown have surfaced across Europe, China, Japan, South Korea, and the UK, marking a significant escalation in Tesla’s efforts to enforce regional software restrictions.
FSD is Tesla’s flagship supervised autonomy package, which is available in several countries across the world. Currently limited by regulatory hurdles, it has not received full approval in most markets outside of the United States due to various things, such as safety standards, data privacy, and local traffic laws.
However, the company is working to expand its availability globally. Nevertheless, Tesla has installed the necessary hardware on vehicles globally, but locks the features based on geographic location.
Some owners have taken accessing FSD into their own hands, using jailbreak or bypass devices.
These “jailbreak” tools, typically €500 USB-style modules that plug into the vehicle’s Controller Area Network (CAN) bus, intercept signals to spoof approvals and unlock FSD, including advanced navigation, Autopark, and Summon features.
Hackers in Poland, Ukraine, and elsewhere have distributed the devices, with some claiming they work on HW3 and HW4 vehicles and can be unplugged to restore stock settings. In China alone, over 100,000 owners reportedly installed such modifications.
Tesla’s response has been swift and uncompromising. Recently, the company began sending in-car notifications and emails warning owners that unauthorized modifications violate terms of service, compromise vehicle safety systems, and expose cars to cybersecurity risks.
The email communication read:
“Your vehicle has detected an unauthorized third-party device. As a precaution, some driver assistance functions have been disabled for safety reasons. A software update will be available soon. Once you install the update, some features may be enabled again.”
Vehicles detected using the hacks have had FSD capabilities remotely disabled without refund. In some cases, owners report permanent bans, even if they had legitimately purchased the software package.
Tesla’s hardline stance underscores its commitment to regulatory compliance and safety.
Tesla has long argued that unsupervised FSD requires rigorous validation, and premature activation could endanger drivers and bystanders.
The crackdown sends a clear-cut message to those who are bypassing the FSD safeguards, but there are greater implications for Tesla if something were to go wrong. This is an understandable way to protect the company’s reputation for its FSD suite.
