Tesla/SpaceX Hyperloop pod sets record 220 mph in test run, 300 mph soon

Published

on

Tesla CEO Elon Musk announced that a “Tesla/SpaceX Hyperloop pusher pod” has bolted down SpaceX’s Hyperloop test track at 355 km/h (220 mph), shattering the previously held Hyperloop pod top speed record of 202 mph set over the weekend.

Musk said in an Instagram post that the Tesla pod could soon reach a top speed of 500 km/h — or half the speed of sound — after “a few tweaks.”

The Tesla/SpaceX Hyperloop pusher pod is used to help propel student Hyperloop pods for SpaceX’s Hyperloop competition. Some of the pods don’t have electric motors used for acceleration, so the pusher pod is used to propel the student pods down the vacuum tube as part of the competition.

As described by Musk, the pusher pod is almost like a tug boat.

“We took the SpaceX/Tesla Hyperloop pusher pod for a spin by itself a few days ago to see what it could do when not pushing student pods,” wrote Musk on Instagram. It’s “kind of like racing with a tugboat.”

Tesla has held two Hyperloop competitions this year with the recent winner, WARR Hyperloop, reaching a top speed of 325 km/h (202 mph).

WARR Hyperloop, an academic Hyperloop group, set the record over the weekend, besting Hyperloop One’s 190 mph record set earlier this year. Musk was reported saying that the WARR team had the best design of the competition, and the thrilling test runs and Musk statements can be viewed in WARR Hyperloop’s livestream.

The test run comes as both Musk and The Boring Company have been rumored to be joining the race to develop the best Hyperloop technology. The Boring Company announced in early August that its tunnels would be used for Hyperloop technology just days after Musk hinted that he wanted to build the Hyperloop project between New York City and Washington, D.C.

In the past, Musk has largely remained on the sidelines of Hyperloop development while companies like Hyperloop One and Hyperloop Transportation Technologies work to make his vacuum sled skate transportation technology a reality.

The SpaceX Hyperloop competition was established for academic groups to test their technology, further encouraging development and trials of the technology that could change transportation around the world.

Grok coming to Tesla vehicles next week “at the latest:” Elon Musk

Elon Musk announced on Thursday that Grok, the large language model developed by his startup xAI, will soon be available in Tesla vehicles. Grok’s rollout to Tesla vehicles is expected to begin next week at the latest, further deepening the ties between the two Elon Musk-led companies.

Tesla–xAI synergy

Musk confirmed the news on X shortly after livestreaming the release of Grok 4, xAI’s latest large language model. “Grok is coming to Tesla vehicles very soon. Next week at the latest,” Musk wrote in a post on social media platform X.

During the livestream, Musk and several members of the xAI team highlighted several upgrades to Grok 4’s voice capabilities and performance metrics, positioning the LLM as competitive with top-tier models from OpenAI and Google.

The in-vehicle integration of Grok marks a new chapter in Tesla’s AI development. While Tesla has long relied on in-house systems for autonomous driving and energy optimization, Grok’s integration would introduce conversational AI directly into its vehicles’ user experience. This integration could potentially improve customer interaction inside Tesla vehicles.

xAI and Tesla’s collaborative footprint

Grok’s upcoming rollout to Tesla vehicles adds to a growing business relationship between Tesla and xAI. Earlier this year, Tesla disclosed that it generated $198.3 million in revenue from commercial, consulting, and support agreements with xAI, as noted in a report from Bloomberg News. A large portion of that amount, however, came from the sale of Megapack energy storage systems to the artificial intelligence startup.

In July 2023, Musk polled X users about whether Tesla should invest $5 billion in xAI. While no formal investment has been made so far, 68% of poll participants voted yes, and Musk has since stated that the idea would be discussed with Tesla’s board.

Tesla Robotaxi to expand Austin coverage, Bay Area launch targeted in coming months

Tesla is preparing to expand its Robotaxi pilot program in Austin, Texas, with the self-driving service set to cover a larger portion of the city this weekend. The CEO shared the update in a post on social media platform X, where he also noted that the company is currently looking at the San Francisco Bay Area as the location for Tesla’s next Robotaxi pilot.

Tesla’s growing Robotaxi pilot

Tesla’s Robotaxi service first launched in Austin last month as a test program. While the vehicles operate without a human in the driver’s seat, a Tesla employee currently rides in the front passenger seat to monitor vehicle performance. Responses to Tesla’s Robotaxi pilot are quite positive, with some users praising the vehicles for their smooth and comfortable rides.

In a later post on X, Musk also stated that Tesla is in the process of seeking regulatory approval to begin operating robotaxis in the Bay Area, adding that a launch there could happen within “a month or two.” The California expansion would be a notable milestone for Tesla, considering its roots in the state.

Robotaxi is key to Tesla’s long-term growth

Autonomous driving remains central to Tesla’s long-term vision. Musk has consistently framed Robotaxis as a future driver of profitability and growth, particularly as EV sales face headwinds across multiple regions. In a way, the expansion of Tesla’s autonomous fleet is expected to play a critical role in differentiating the company’s offerings in a crowded electric vehicle market.

Tesla has yet to specify when the Robotaxi service will transition out of its testing phase or how it plans to monetize the platform, as the company is only charging a flat fee of $4.20 per ride in its Austin pilot program today. However, its growing geographic footprint suggests the company is steadily progressing toward wider deployment.

xAI, the artificial intelligence company founded by Elon Musk, has officially launched its latest flagship models, Grok 4 and Grok 4 Heavy. Alongside the release, the company introduced its most premium subscription tier to date, SuperGrok Heavy, which is priced at $300 per month and targeted at power users and developers.

Grok 4 is designed to compete with top-tier AI models like OpenAI’s ChatGPT and Google’s Gemini. As per xAI, Grok 4 demonstrates frontier-level performance across several benchmark evaluations. 

On Humanity’s Last Exam, an extensive test designed to evaluate general knowledge, Grok 4 scored 25.4% without using external tools, outperforming OpenAI’s o3 (high), which scored 21%, and Gemini 2.5 Pro, which scored 21.6%. 

When equipped with tools, Grok 4 Heavy scored 44.4%, making it the top-performing model in that category. For context, Gemini 2.5 Pro with tools scored 26.9%, as noted in a TechCrunch report.

xAI also highlighted Grok 4 Heavy’s “multi-agent” system, which enables multiple instances of the model to solve a problem in parallel and compare answers, similar to a study group. This collaborative approach is intended to improve both reasoning and accuracy in complex tasks.

The company also shared results from the ARC-AGI-2 benchmark, where Grok (Thinking) achieved new state of the art (SOTA) score on the test with 15.9%. As per Arc Prize in a post on X, this score is “nearly double(s) the previous commercial SOTA and tops the current Kaggle competition SOTA.”

The $300/month SuperGrok Heavy plan grants users early access to Grok 4 Heavy, as well as upcoming product features. Upcoming capabilities that are planned for release in the coming months include an AI coding model in August, a multi-modal agent in September, and a video generation system in October.

Grok 4 and Grok 4 Heavy are available via API as part of xAI’s push to engage developers and enterprise users. The company’s enterprise platform, which launched just two months ago, will also expand via partnerships with cloud hyperscalers to bring Grok models to broader infrastructure environments.
