Tesla Battery Day vs. Volkswagen Power Day: How Wall Street reacted
Tesla’s Battery Day and Volkswagen’s Power Day were two similar events that showed how the two automakers plan to combat electric vehicle prices within the next few years. Despite the similarities in the events, Wall Street reacted quite differently to both, with Tesla (NASDAQ: TSLA) seeing a minimal effect on its stock in the days following. However, Volkswagen’s stock (OTCMKTS: VWAGY) is soaring over 12% on the day after the event.
Tesla Battery Day
Tesla’s Battery Day was a marquee event for the electric automaker. While the previous year’s focus was Autonomy, 2020 saw battery cells as Tesla’s main concentration. During the event, CEO Elon Musk revealed how Tesla would combat battery prices by continuing to source cells from third-party suppliers, but also by developing its own 4680 cells that are produced by the company in-house. Additionally, new structural battery packs are being used to house the cells and also provide a more robust crash response in the event of an accident. The rigidity of the new structural battery intends to take Tesla’s safety ratings through the roof, where they already reside.
Tesla also revealed plans for a $25,000 car, a blueprint to manufacture 20 million cars per year, and a roadmap to massive cuts in battery cell production costs.

Despite the developments, Tesla didn’t receive a big boost on Wall Street. Interestingly, despite the massive developments and plans that Tesla had revealed during the Battery Day event on September 22nd, 2020, the stock closed at $424.23. The day following saw an 11% drop in the stock, as it closed at $380.36.
Many didn’t understand the reason for the drop. Tesla bull and investor Jim Cramer, who was at one time bearish on the automaker’s stock, stated that the stock fell simply because Tesla didn’t announce what some were expecting. “They’re just bummed the things they hyped didn’t happen,” Cramer said. “Tesla rolls out a plan to create an electric car for the masses and greeted with a yawn because Musk didn’t roll out a magic battery. This is what happens when you let expectations get out of control.”
Volkswagen Power Day
Volkswagen’s Power Day was, in effect, the German automaker’s version of Tesla’s Battery Day. The company held an event outlining their plans for cell cost reductions, along with plans for six total production plants across Europe. VW also has established several partnerships with European energy companies to roll out an expansive charging infrastructure, among many other developments.
“We aim to reduce the cost and complexity of the battery and at the same time increase its range and performance,” Volkswagen Group Board Member for Technology Thomas Schmall said. “We will use our economies of scale to the benefit of our customers when it comes to the battery too. On average, we will drive down the cost of battery systems to significantly below €100 per kilowatt-hour. This will finally make e-mobility affordable and the dominant drive technology.”
Volkswagen’s Power Day: Six new cell plants, new unified battery cell, charging network partnerships
Volkswagen stock began Monday’s trading session at $28.38. After the developments that VW announced, the stock shot up $1.38, a boost of 4.86%. However, the German company’s stock is enjoying massive gains today, just one day after the big event. After closing at $29.76 yesterday, VW stock has increased another 3.48% at the time of writing, for a total gain of 11.69% as of 2:30 PM EST.
The differences in the presentations and how Wall Street has responded to them are unknown. However, the sheer size of Volkswagen’s production figures could be the main reason for the increased investor response. While Tesla’s rollout of 500,000 vehicles in 2020 was a company best, Volkswagen delivered 9.3 million vehicles last year. For context, VW has also been around since 1937, while Tesla has only produced a mass-market vehicle since 2017.
Tesla is undoubtedly the leader in electric vehicles. Volkswagen, while still working out software kinks, could be considered second-place by some because of the successful adaptation of the ID. family of vehicles in Europe so far. However, it is still admittedly ironing out some software issues with its MEB platform, and it seems somewhat odd that VW’s stock received such a healthy boost in the day following its Power Day event.

Tesla App now shows you what your Supercharger will look like upon arrival
The Tesla App is now giving owners a better indication of what to expect when visiting a Supercharger site, as it is now sharing Site Maps in the app itself, making the feature no longer exclusively available in the car.
Tesla owners can now preview a Supercharger’s layout and live stall status from their phone thanks to the App’s new software version, v4.61.0. Zooming into a supported Supercharger on the charging map now switches the familiar street view into a site-specific map that shows stall positions, occupied bays, out-of-service posts, and a live count of open Superchargers.
It will even show you which specific Tesla model is charging at each occupied stall.

This is the same view drivers first saw inside the car with the 2025 Holiday Update, which started as a pilot for Tesla in California and Texas. Those early maps showed layout, nearby amenities, and the status of each operational stall. The feature has spread to most Superchargers in the U.S., but now Tesla wants the feature available through the Smartphone App, which is now rolling out to owners.
The in-vehicle screen maps remain a richer 3D canvas and originally required AMD Ryzen infotainment hardware, which left many Intel-based Model 3 and Model Y owners without the view. The app version removes that hardware barrier, so any owner can now get a preview of their upcoming Supercharger stop on their phone.
Anyone with the updated version of the app can open a Site Map on their phone. The feature has provided some additional peace of mind to anxious travelers and those who might be looking for a place that is less congested for faster charging speeds. It is a meaningful addition to many owners, especially for trips to unfamiliar locations.
You can now pick a Supercharger location that might be more aligned with what you are looking for or need: you can pick a site based on what stalls are open, where ADA stalls sit, how you will pull in, and more, instead of circling a crowded lot after arriving. Owners of older cars now have access to the feature without having to purchase a new vehicle altogether.
Site Mpas will not reserve a stall, nor will it change how Fast Charging works. Tesla does something simpler and more useful by giving owners a dedicated preview of the Supercharger they’re about to charge, turning an unknown parking lot into a place that may seem more familiar thanks to the preview.

Tesla Optimus Gen 3 shows off a cleaner, factory-ready design in new app discovery
Renders hidden inside Tesla’s Android app show Optimus Gen 3’s design before any official reveal.
Tesla may have accidentally given a first look at its newest Optimus Gen 3 humanoid robot when photos were found in the Tesla smartphone app.
Design files tucked inside a recent Android version of the Tesla app appear to show the third generation humanoid robot next to the older Gen 2.5 prototype. The assets were extracted from the app package by Tesla community member @wholemars, who posted the renders on X late Tuesday night before deleting them. The Tesla Newswire reshared the side by side comparison on Wednesday, and the images have circulated widely since.

The files are labeled “gen3” and were built as models for Tesla app’s own interface, as validated directly by Grok to be official.
The comparison shows a robot that looks built for a factory line rather than a lab bench. Gen 2.5’s exposed mechanical linkages and gold plating on the knees and shins are gone. In their place, Gen 3 uses matte black fairings on the lower legs, paired with a more contoured champagne gold body. Flexible covers now seal the joint where the torso meets the upper thighs, keeping bearings and moving parts sealed from debris and unnecessary contact.
The body panels fit more tightly, and the hands, which Tesla has said carry 22 degrees of freedom, look far more refined than those on earlier units.
This most recent leak fills a gap Tesla has left open for most of the year. Elon Musk said on March 31 that Optimus 3 was walking around but needed “some finishing touches” before it could be shown, a delay Teslarati covered when Tesla missed its first quarter reveal target. Musk later said Tesla would hold the design back until closer to production, partly to keep competitors from copying it. No reveal date has been announced.
The app itself has been preparing for Optimus for months. In July, code in the Tesla app pointed to a dedicated robot phone key, a consent screen for collecting video and spatial data while Optimus works inside a home, and an alert system for low battery and mechanical faults. Finished 3D models of Gen 3 suggest the interface owners will eventually use is moving past placeholder code toward something Tesla intends to ship.
Manufacturing is moving in parallel. Tesla tore out the original Model S and Model X lines at Fremont this summer to make room for Optimus production, with a planned capacity of one million robots a year. At Giga Texas, the steel frame of a dedicated Optimus factory is nearing completion ahead of a targeted 2027 start, with Musk pointing to an eventual output of 10 million units annually.

Tesla Semi lands the biggest electric truck deal in U.S. history
Tesla leads a record 2,500 truck order, but not every truck will be a Semi.
Tesla has landed the largest electric truck order in U.S. history. ZET SCALE, a new alliance of shippers and carriers, named Tesla its primary manufacturer on Tuesday for an initial order of 2,500 electric Class 8 trucks. The deal alone would nearly double the number of electric heavy trucks operating in the country.
According to the press release from Catalyst Mobility, the nonprofit formerly known as CALSTART, Kenworth, RIDE and Volvo were also selected as secondary manufacturers that carriers can pick if their operations call for it. No split between the four brands has been published, so the exact number of Semis in the order is not yet known.

Tesla won the top slot through a competitive request for proposals. The alliance, which Catalyst Mobility runs with the Smart Freight Centre, scored bidders on price, range, charging capability and production capacity. Pooling freight demand from founding shippers, including Microsoft and PepsiCo, let every truck maker bid lower than it would for a single fleet. “The Tesla Semi is designed for lower cost per mile operations than diesel,” said Dan Priestley, director of the Tesla Semi program, as noted in the press release.
The financing is built to pull in carriers who have avoided electric trucks. ZET Financial is issuing the purchase order for all 2,500 units and will place them with fleets through a fair market value lease. The trucks will be deployed over the next few years across 10 freight hubs in Los Angeles, Stockton, Bakersfield, Seattle and Tacoma, Houston, Dallas, San Antonio, Chicago, Atlanta, and the Newark and New York area. ZET SCALE says the first order is only the opening round, with a longer term goal of 10,000 trucks or more.
Even if Tesla ends up with only a majority share, it would still be the biggest Semi deal to date. Einride’s 500 unit order in August was the previous record, and WattEV’s 370 truck order in May was the largest California deal at the time. Einride’s CEO has since said he expects all 500 trucks delivered by the end of 2027.
The announcement lands two days before Tesla formally inaugurates its Semi factory in Nevada on September 24. The 1.7 million square foot plant sits next to Gigafactory Nevada’s 4680 cell lines and is designed for 50,000 trucks a year.
