Tesla recently rolled out an update to its vehicles’ navigation system that makes energy consumption calculations incredibly accurate. The update was released as part of software version 2022.16.0.2. 

Prior to the update, Tesla’s navigation system predicted a vehicle’s energy usage using data like distance, elevation changes, and other information like the type of wheels that are installed. Through this feature, drivers were able to view the estimated energy available in their vehicles when they arrived at their destination

Tesla’s update 2022.16.0.2 pushes this feature further, with the navigation system now taking into account factors such as wind conditions, potential crosswinds, humidity, and ambient temperature when predicting a vehicle’s energy usage. This additional weather data should provide Teslas with more accurate energy consumption estimates. 

Tesla announced the update through its official Twitter account. “Tesla navigation will now take predicted crosswind, headwind, humidity & temperature into account for calculating battery % on arrival. This is in addition to current factors: predicted speed, HVAC use, elevation changes, current temperature, and route/distance,” Tesla wrote. 

Considering that Tesla’s navigation energy prediction system will be using additional weather information, vehicles must have an active cellular connection to support the updated feature. This could be an issue for some older vehicles like early Tesla Model S units that are not equipped with a 4G/LTE modem.

AT&T retired its 3G cellular service this February 2022. As a result, Teslas that are only equipped with 3G connectivity have lost features such as remote unlock, live traffic updates, cabin preconditioning, Supercharger availability, and navigation. Owners whose vehicles are affected by AT&T’s retirement of its 3G cellular networks are advised to take advantage of Tesla’s LTE modem upgrade, which costs $200.

thyssenkrupp Supply Chain Services has completed a three-week pilot of the Tesla Semi at one of its California logistics hubs, marking a new step in the company’s sustainability push. The test covered nearly 5,000 miles in winter conditions and focused on evaluating the electric Class 8 truck’s efficiency, transparency, and operational performance.

Tesla Semi offers efficiency gains and real-time logistics visibility

During the pilot, the Tesla Semi was used for active freight delivery, including routes over the Altamont Pass. thyssenkrupp evaluated the vehicle’s ability to reduce downtime, enhance delivery speed, and offer greater real-time supply chain visibility, the company noted in a press release.

Live diagnostics and performance monitoring allowed the logistics provider to track metrics such as speed, routes, and overall efficiency—data that supports smarter and more transparent logistics operations.

“The Tesla Semi aligns with our ongoing commitment to sustainability and operational excellence,” said Bob Denehy, Chief Commercial Officer at thyssenkrupp Supply Chain Services. “Its efficiency and diagnostic features, and low environmental impact make it a natural fit for our evolving logistics strategy.”

Pilot builds on long-term partnership with Tesla and green energy goals

A logistics partner to Tesla since 2015, thyssenkrupp Supply Chain Services was one of the first companies selected to test the Tesla Semi in a real-world setting. The trial reinforces the company’s push into renewable energy logistics and reflects its long-term goal of integrating alternative-fuel technologies across its operations.

Plans are now underway to begin adding electric Semis to its fleet as part of a wider emissions-reduction effort. The pilot is thus the latest example of how logistics providers are embracing next-generation transport technologies to meet environmental goals and enhance supply chain performance.

ArcBest has successfully wrapped up a three-week pilot program testing a Class 8 Tesla Semi in over-the-road applications. The trial was conducted through ArcBest’s ABF Freight division, and it covered routes between Reno and Sacramento and regional operations around the Bay Area.

Tesla Semi pilot sees strong performance and positive driver feedback

The Tesla Semi logged 4,494 miles during the pilot, averaging 321 miles per day with an energy efficiency of 1.55 kWh per mile. The Tesla Semi handled varied terrain, including a 7,200-foot climb over Donner Pass, and delivered performance comparable to diesel counterparts. 

Drivers who participated in the pilot also gave positive feedback to the Tesla Semi, citing the Class 8 all-electric truck’s comfort, safety, and visibility thanks to features like a center seating position and intuitive controls. Matt Godfrey, president of ABF Freight, shared his thoughts on the pilot in a press release

“We’re not looking for a truck that performs well ‘for an EV.’ It must meet or exceed the performance and total cost of ownership targets of our most efficient diesel units. This pilot gives us great insight into the potential of EV semis in our operations,” he said. 

ArcBest highlights need for more charging infrastructure

While the pilot met expectations, ArcBest noted that broader deployment of Class 8 all-electric trucks like the Tesla Semi will still depend on improvements in charging infrastructure. This way, longer-haul operations become more than feasible.

The pilot marks another step in ArcBest’s investment in sustainable logistics technologies. In addition to testing the Tesla Semi, the company operates a small fleet of EVs, including nine electric yard tractors, two electric forklifts, and two Class 6 electric straight trucks. Dennis Anderson, ArcBest chief innovation officer, noted that vehicles like the Tesla Semi are notable developments in the transportation sector.

“Freight transportation is a vital part of the global economy, and we know it also plays a significant role in overall greenhouse gas emissions. While the path to decarbonization presents complex challenges — such as infrastructure needs and alternative fuel development — it also opens the door to innovation. Vehicles like the Tesla Semi highlight the progress being made and expand the boundaries of what’s possible as we work toward a more sustainable future for freight,” he stated.

Tesla could save $2.5B by replacing 10% of staff with Optimus: Morgan Stanley

Tesla’s (NASDAQ:TSLA) near-term outlook may be clouded by political controversies and regulatory headwinds, but Morgan Stanley analyst Adam Jonas sees a glimmer of opportunity for the electric vehicle maker. 

In a new note, the Morgan Stanley analyst estimated that Tesla could save $2.5 billion by replacing just 10% of its workforce with its Optimus robots, assigning each robot a net present value (NPV) of $200,000.

Morgan Stanley highlights Optimus’ savings potential

Jonas highlighted the potential savings on Tesla’s workforce of 125,665 employees in his note, suggesting that the utilization of Optimus robots could significantly reduce labor costs. The analyst’s note arrived shortly after Tesla reported Q2 2025 deliveries of 384,122 vehicles, which came close to Morgan Stanley’s estimate and slightly under the consensus of 385,086.

“Tesla has 125,665 employees worldwide (year-end 2024). On our calculations, a 10% substitution to humanoid at approximately ($200k NPV/humanoid) could be worth approximately $2.5bn,” Jonas wrote, as noted by Street Insider.

Jonas also issued some caution on Tesla Energy, whose battery storage deployments were flat year over year at 9.6 GWh. Morgan Stanley had expected Tesla Energy to post battery storage deployments of 14 GWh in the second quarter.

Musk’s political ambitions

The backdrop to Jonas’ note included Elon Musk’s involvement in U.S. politics. The Tesla CEO recently floated the idea of launching a new political party, following a poll on X that showed support for the idea. Though a widely circulated FEC filing was labeled false by Musk, the CEO does seem intent on establishing a third political party in the United States. 

Jonas cautioned that Musk’s political efforts could divert attention and resources from Tesla’s core operations, adding near-term pressure on TSLA stock. “We believe investors should be prepared for further devotion of resources (financial, time/attention) in the direction of Mr. Musk’s political priorities which may add further near-term pressure to TSLA shares,” Jonas stated.
