Tesla Semi returns to Des Moines, IA as road tests and customer visits continue
Just a few days after visiting UPS’ hub in Addison, IL, the Tesla Semi has been spotted in Des Moines, IA. The Semi’s interstate travels appear to be part of the company’s continued road tests, which also involve visits to some of its reservation holders.
This is actually not the first time the Tesla Semi was photographed in Des Moines. Last April, the matte black Tesla Semi, an operational prototype that has not been spotted on roads lately, was sighted being transported heading east into I-80 in the Des Moines, IA area. Des Moines hosts the headquarters of Ruan Transportation Management Systems, one of Tesla’s reservation holders for the Semi.
Ruan noted in an announcement back in January that it had been in touch with Tesla about the upcoming all-electric long-hauler even before the Semi was unveiled in November. Over the months leading up to the vehicle’s reveal, Ruan was invited by Tesla to take part in on-site meetings and discussions about the vehicle.
Ruan announced an order of 5 Tesla Semis in January, though it has not provided an update since then. Considering that the Tesla Semi has been making the rounds visiting some reservation holders like J.B. Hunt and UPS, it would not be too surprising if Ruan’s headquarters would soon get a visit from the prototype electric truck as well.
Tesla’s recent visits and sightings are quite notable, in the way that the company appears to be adopting a more open stance about the vehicle. Anecdotes from members of the Tesla community fortunate enough to come across the Semi indicate that the team accompanying the truck are incredibly willing to answer any questions about the long-hauler. Apart from this, the truck’s recent visits to reservation holders like J.B. Hunt and UPS were also a lot more hands-on and interactive. The truck’s recent visit at the Addison, IL UPS hub, for one, even involved rides (and seemingly even test drives) in the vehicle.
Tesla had around 2,000 reservations for the Semi as of the Q1 2018 earnings call last May. The company has not issued an update on the number of pre-orders for the truck since then, though Elon Musk noted during the Q2 2018 earnings call that Tesla is still in the process of improving the vehicle’s capabilities before it enters production.
The Tesla Semi could be the company’s most disruptive vehicle in its lineup, considering that the trucking industry is responsible for the transportation of up to 71% of food, retail goods, construction supplies, and other cargo delivered to customers and businesses every day. The industry is steadily growing as well, with the trucking market generating $700.3 billion in economic activity last year, a 3.5% increase compared to the $676.6 billion it made in 2016.
Just like Tesla’s other vehicles, the Semi boasts impressive specs. The electric truck is powered by four Model 3-derived electric motors, which give it instant torque. The Semi is also rated as a Class 8 truck, and is listed with a 0-60 mph time of 5 seconds flat when accelerating without cargo. The Semi is expected to be released in two variations — a 300-mile short-range variant and a 500-mile long-range version. That said, Elon Musk has noted that the long-range Semi could have closer to 600 miles of range per charge.
Tesla announced its Spring 2026 software update, and it’s the most feature-dense seasonal release the company has put out. The update covers twelve named changes spanning FSD, voice AI, safety lighting, dashcam storage, and pet display customization, among other things.
The centerpiece for owners with AI4 hardware is a redesigned Self-Driving app. The new interface lets owners subscribe to Full Self-Driving with a single tap and view ongoing FSD usage stats directly in the vehicle.
Grok gets its biggest in-car upgrade yet. The update adds a “Hey Grok” hands-free wake word along with location-based reminders, so a driver can now say “remind me to pick up groceries when I get home” without touching the screen. Grok first arrived in vehicles in July 2025, but each update has pushed it closer to genuine daily utility. Musk framed the broader vision clearly at Davos in January, saying Tesla is “really moving into a future that is based on autonomy.”
On safety, the update introduces enhanced blind spot warning lights that integrate directly with the cabin’s ambient lighting, building on the blind spot door warning that arrived in update 2026.8.
Dog Mode has been renamed Pet Mode and now lets owners choose a dog, cat, or hedgehog icon and add their pet’s name to the display.
Dashcam retention now extends up to 24 hours, up from the previous one-hour rolling loop, with a permanent save option for any clip. Weather maps now show rain and snow with better color differentiation and include the past hour of precipitation data along the route.
Tesla has now established a clear rhythm of two major OTA pushes per year. As with last year’s Spring update, that cycle started taking shape in 2025 with adaptive headlights and trunk customization. The 2025 Holiday Update then added Grok to the vehicle for the first time. This Spring follows that structure: the Holiday update introduces new architecture, and the Spring update broadens it across the fleet.
Two notable features still did not make it. IFTTT automations, which launched in China earlier this year, were held back from this North American release for unknown reasons, and Apple CarPlay remains absent, reportedly still delayed by iOS 26 and Apple Maps compatibility issues.
Below is the full list of feature updates released by Tesla.

Tesla launches new Model Y interior option
Produced at Gigafactory Shanghai, the update applies to all five-seat Premium Model Y configurations and started being seen on customer deliveries this week. The move marks the first major interior refresh for the compact crossover since its global debut.
Tesla has rolled out a striking new interior choice for its best-selling Model Y in China, replacing the long-familiar white cabin with a fresh option: Zen Grey.
Produced at Gigafactory Shanghai, the update applies to all five-seat Premium Model Y configurations and started being seen on customer deliveries this week. The move marks the first major interior refresh for the compact crossover since its global debut.
The Zen Grey interior swaps the classic black-and-white contrast for a softer, more unified palette. Seats, door panels, and center console trim now feature a warm light-grey tone that covers far more surface area than before.
Previously, black accents on the console, door handles, and lower dashboard are now color-matched in the same pebbled vegan leather, creating a brighter, less clinical cabin.
Tesla describes the material as durable and easy to maintain while delivering a noticeably more premium feel. Early photos and videos from Chinese owners show the new shade reflecting natural light beautifully, giving the spacious Model Y an even airier, more inviting atmosphere without sacrificing the minimalist design customers expect:

The change is not an added-cost upgrade but a direct replacement for the discontinued white interior on Shanghai-built vehicles. Customers configuring a new Model Y in China, Hong Kong, or Macau now see Zen Grey as the default light-colored choice.
The update also flows to export markets supplied by Giga Shanghai, including Australia, New Zealand, South Korea, Japan, and the Philippines. Tesla has used its Chinese factory as an innovation hub before, and executives appear to be testing broader appeal with this subtler, warmer tone that avoids the high-maintenance reputation sometimes associated with bright white leather.
Beyond the interior, the refreshed Model Y from Shanghai includes minor exterior tweaks such as blacked-out badges on some trims and optional dark 20-inch wheels.
These changes arrive as Tesla faces stiff competition from domestic EV makers in its largest market. By refreshing the Model Y’s cabin without raising prices, the company is signaling continued commitment to value and constant improvement.
With over 1.2 million Model Y units already on Chinese roads, the Zen Grey launch gives existing owners a fresh talking point and new buyers another reason to choose Tesla. As deliveries ramp up this month, the updated interior is expected to become the dominant light-colored choice across the Asia-Pacific region.
Tesla has not yet confirmed whether the Zen Grey will reach Fremont, Austin, or Berlin-built Model Ys, but Shanghai’s track record suggests the option could spread quickly if customer feedback remains strong.

Tesla launches 200mph Model S “Gold” Signature in invite-only purchase
Tesla’s final 350-unit Signature Edition closes the book on two cars that changed everything.
Tesla has announced a super limited Signature Edition run of 250 Model S Plaid and 100 Model X Plaid units as an invite only purchase in a bid to give its original flagship vehicles a proper send-off.
When the Model S first launched in 2012, the first 1,000 units sold were “Signature” editions that required a $40,000 deposit and cost nearly $100,000 each. Those early buyers were Tesla’s first real believers. This new Signature Edition deliberately echoes that moment, bookending a 14-year run with numbered collector hardware.
Both models are finished in an exclusive Garnet Red paint not available on any current Tesla production vehicle, with gold Tesla T badges up front, a gold Plaid badge and Signature badge at the rear, and a white Alcantara interior featuring gold Plaid seat badges, gold piping, Signature-marked door sills, and a numbered dash plate. The Model S adds carbon ceramic brakes with gold calipers. Every unit ships with Tesla’s Luxe Package, bundling Full Self-Driving (Supervised), four years of Premium Service, free lifetime Supercharging, and a Signature Edition key fob. Both are priced at $159,420, a roughly $35,000 premium over standard Plaid inventory.
The discontinuation is part of a broader strategic shift. At Tesla’s Q4 2025 earnings call, Musk described the decision as “slightly sad” but necessary, saying: “It’s time to basically bring the Model S and X programs to an end with an honorable discharge, because we’re really moving into a future that is based on autonomy.”
The Fremont factory floor that built these cars is being converted to manufacture Optimus humanoid robots, with a target of one million units annually.
