GM recently took the wraps off the Hummer EV, its first foray into the budding all-electric pickup truck market. Inasmuch as the vehicle’s five-minute video unveiling was compelling, it soon became evident that the impressive feats being showcased by the Hummer EV in its reveal were not necessarily real. Soon, a GM engineer reportedly admitted that the company doesn’t have a fully-functioning prototype of the Hummer EV yet, and the vehicle shown in the unveiling was computer-generated.
Yet despite this, the Hummer EV has garnered a significant amount of praise, even from veteran auto reviewers. Doug DeMuro, one of the most prolific car reviewers on YouTube, remarked that the Hummer EV seemed to be farther along in its development compared to rivals such as the Tesla Cybertruck and the Rivian R1T. This statement unsurprisingly caught the ire of the Tesla enthusiast community, and it did not take long before legitimate arguments against the Hummer EV were dismissed since they were coming from a “Tesla fanboy” angle.
But let’s forget Tesla and the Cybertruck for a minute.
Even if one removes Tesla and its post-apocalyptic steel triangle on wheels out of the equation, the Hummer EV still fails to do justice to the EV efforts of rival automakers, both veterans and newcomers alike. This is especially notable when it comes to the all-electric vehicles that companies like Ford, Porsche, Rivian, and Polestar have created. Compared to the Mustang Mach-E, the Rivian R1T, the Polestar 2, and the Porsche Taycan—even the Ford F-150 Electric—the Hummer EV is barely more than CGI.
This was highlighted by electric vehicle veteran and enthusiast Sean Mitchell, who noted that the display unit Hummer EV showcased in the all-electric pickup’s early reviews had an electrical cord running from the truck to a plug. This is common practice for vehicles that are placed in displays, as it prevents batteries from being discharged. There is only one issue: the Hummer EV is supposed to be equipped with a massive 200 kWh battery, a pack that could, at least theoretically, power the truck’s electronics for weeks on its own.
Granted, later comments from reviewers such as DeMuro noted that they did see a moving Hummer EV display unit during their initial review of the vehicle. This is a low bar, however, as a small motor and a small battery pack could have been used to propel the vehicle. This is something that has not been done by GM’s competitors. Multiple Porsche Taycans were driven onstage during the car’s unveiling, for example, and the Rivian R1T was fully-functioning when it was showcased for the first time. Even the Mustang Mach-E and Polestar 2 had working units that needed no electrical cord when they were unveiled.
With these in mind, as well as the fact that reports have pointed at the Hummer EV only being 18 months into its development cycle, it does seem to be a stretch to argue that the Hummer EV is farther along in its production than its competitors. The F-150 Electric, a truck that Ford notes will be produced in a few years, already has a prototype that is capable of pulling a train car that weighs 1 million pounds. The Rivian R1T, a truck that has spent years in development, recently completed an eight-day rally over 2,000 kms. That’s something that the Hummer EV seems to be capable of doing only in CGI, at least for now.
GM intends to start delivering the Hummer EV in Fall 2021. Rivian, for its part, is aiming to start deliveries of its very-much-production-ready R1T by mid-2021. The Tesla Cybertruck is also poised to begin deliveries by the end of next year.

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 expands ridesharing service in California to new hotspot
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.
Our Bay Area rideshare service now goes to SFO ✈️
— Tesla AI (@Tesla_AI) July 21, 2026
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.
