Tesla wraps matte black Semi prototype in stunning red amid continued road tests
Tesla has seemingly decided to spice up the road tests of its all-electric truck, wrapping one of its test mules in a stunning matte red color. The vehicle, which has caught the attention of the Tesla community, was spotted on the 405 in LA, before being sighted in the Kettleman City Supercharger.
While Tesla’s silver and matte black Semi prototypes are eye-catching trucks in their own right, there is no doubt that the matte red wrap makes the vehicle downright stunning. Inasmuch as initial sightings of the red test mule suggested that Tesla had produced another prototype, though, details such as the truck’s license plate and its trailer proved that the vehicle was just a wrapped version of the matte black prototype that Elon Musk debuted during the long-hauler’s unveiling.
Unlike prior sightings of the Semi, the matte red test mule appears to have stayed at the Kettleman City Supercharger for a rather long time. Tesla enthusiast and r/TeslaMotors member u/CardSpecialist, who sighted the vehicle in the Supercharger after sundown, noted that he was able to speak briefly with the Semi’s driver. According to the Tesla enthusiast, the driver of the vehicle stated that the red wrap has been getting a lot more looks compared to the truck’s previous matte black paint scheme.

Tesla is yet to provide any details behind its decision to change the color of one of its Semi test mules. That said, the new wrap does make the vehicle stand out more, resulting in more visibility for the upcoming all-electric long-hauler. With such an eye-popping color scheme, after all, the vehicle would likely catch the attention of even more potential reservation holders.
The Tesla Semi might be taking a backseat to the Model 3 for now, but the vehicle has a lot of potential to disrupt a very lucrative industry. To say that the trucking market presents a huge opportunity for Tesla is an understatement, considering that it is responsible for handling the transportation of up to 71% of the United States’ food, retail goods, and other cargo being delivered every day. The American Trucking Associations’ American Trucking Trends 2018 report, for one, noted that the US trucking industry generated $700.3 billion in economic activity last year. This is a market that Tesla could breach if the Semi proves to be a success.
The Tesla Semi definitely appears to have the necessary goods to disrupt the trucking industry. The Semi is a Class 8 truck, allowing it to haul a considerable amount of cargo. Performance-wise, the Semi also stands to shame its diesel counterparts, thanks to its four Model 3-derived electric motors that allow it to accelerate from 0 to 60 mph in 5 seconds flat without a trailer. With a full load, the Semi reaches highway speeds in 20 seconds, considerably faster than its fossil fuel-powered counterparts.
The Tesla Semi is also set to be equipped with semi-autonomous features. Among these is “Convoy Mode,” which would allow multiple trucks to semi-autonomously draft in close proximity with each other. Concept videos of the feature posted by Tesla show one manned Semi leading a couple of unmanned electric trucks. Musk noted during the vehicle’s unveiling that the Semi’s convoy tech is something that Tesla can already accomplish today.
The Tesla Semi is expected to start production sometime in 2019, though later statements from Tesla head of investor relations Martin Viecha suggested that the company would “earnestly” start producing the vehicle by 2020.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn
— Elon Musk (@elonmusk) July 21, 2026
The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
Tesla has extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.
The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.

Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.
The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.
UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch
This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.
The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.
Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.
The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.
