SpaceX/Tesla’s Hyperloop pod will attempt to reach 1/2 speed of sound
Elon Musk recently announced that a speed test for the upgraded SpaceX Hyperloop pod would be conducted soon. This time around, Musk said that the goal would be to accelerate to half the speed of sound and stop within ~1.2 km.
Musk’s updates came late Saturday on Twitter. Expanding on a tweet he posted last August about the SpaceX Hyperloop pusher pod, Musk candidly stated that the new goal for the upcoming speed test would be “kinda nutty.” Accelerating from a standstill to a blazing 383.7 mph (half the speed of sound) in around 1.2 km, after all, is a pretty challenging endeavor.
Despite the risks, however, Musk lightly joked that the upgraded Hyperloop pod’s speed test would be exciting nonetheless.
“This is kinda nutty for such a short distance, so could easily end up being shredded metal, but exciting either way,” Musk tweeted.

During a post on Instagram last year, Musk said that the SpaceX team decided to see how fast the pusher pod could go on its own, considering that the machine had mostly been used to push some of the pods of the competing student teams. According to Musk, the Hyperloop pusher pod was able to hit 220 mph before things started heating up. Thus, if the machine could dash to half the speed of sound this time around, it would be a notable accomplishment.

The upcoming speed test of the upgraded SpaceX Hyperloop pusher pod comes as the 2018 Hyperloop Pod Competition draws nearer. The 2018 competition, which is set to take place on July 22, 2018, will see teams of students from across the globe compete in a contest to see which could come up with the best design for a Hyperloop pod. According to SpaceX’s page for the competition, teams this year will be focusing on one particular metric — maximum speed.
Over the past couple of years, WARR Hyperloop, a team from the Technical University of Munich, has managed to win the competition. Last year, the students built a lightweight pod that was propelled with a 50 kW electric motor and connected to polyurethane wheels. During the contest, WARR Hyperloop’s 190-lb machine was able to hit 202 mph, blowing away its two toughest competitors — Paradigm Hyperloop and SwissLoop.
WARR Hyperloop is preparing to defend their title for this year’s competition. According to the group’s official website, the WARR Hyperloop team for 2018 will be comprised of 45 members from 16 different countries. A brand new pod is also under development.
As we noted in a previous report, Elon Musk’s Hyperloop idea has inspired Dubai to commit to the project. Just recently, a full-scale prototype model of a Hyperloop One passenger pod was unveiled in Dubai’s City Walk Mall. The 8.7-meter-long, 3.3-meter-diameter pod featured various plush amenities, including BMW-designed seats, generous legroom, and a lighting scheme that would not look out of place in a sci-fi movie.
Dubai’s Hyperloop system is expected to start operations as early as 2020, with the ultra-high-speed transport system connecting key cities in the region, such as Abu Dhabi and Dubai.

Nvidia CEO Jensen Huang explains difference between Tesla FSD and Alpamayo
“Tesla’s FSD stack is completely world-class,” the Nvidia CEO said.
NVIDIA CEO Jensen Huang has offered high praise for Tesla’s Full Self-Driving (FSD) system during a Q&A at CES 2026, calling it “world-class” and “state-of-the-art” in design, training, and performance.
More importantly, he also shared some insights about the key differences between FSD and Nvidia’s recently announced Alpamayo system.
Jensen Huang’s praise for Tesla FSD
Nvidia made headlines at CES following its announcement of Alpamayo, which uses artificial intelligence to accelerate the development of autonomous driving solutions. Due to its focus on AI, many started speculating that Alpamayo would be a direct rival to FSD. This was somewhat addressed by Elon Musk, who predicted that “they will find that it’s easy to get to 99% and then super hard to solve the long tail of the distribution.”
During his Q&A, Nvidia CEO Jensen Huang was asked about the difference between FSD and Alpamayo. His response was extensive:
“Tesla’s FSD stack is completely world-class. They’ve been working on it for quite some time. It’s world-class not only in the number of miles it’s accumulated, but in the way it’s designed, the way they do training, data collection, curation, synthetic data generation, and all of their simulation technologies.
“Of course, the latest generation is end-to-end Full Self-Driving—meaning it’s one large model trained end to end. And so… Elon’s AD system is, in every way, 100% state-of-the-art. I’m really quite impressed by the technology. I have it, and I drive it in our house, and it works incredibly well,” the Nvidia CEO said.
Nvidia’s platform approach vs Tesla’s integration
Huang also stated that Nvidia’s Alpamayo system was built around a fundamentally different philosophy from Tesla’s. Rather than developing self-driving cars itself, Nvidia supplies the full autonomous technology stack for other companies to use.
“Nvidia doesn’t build self-driving cars. We build the full stack so others can,” Huang said, explaining that Nvidia provides separate systems for training, simulation, and in-vehicle computing, all supported by shared software.
He added that customers can adopt as much or as little of the platform as they need, noting that Nvidia works across the industry, including with Tesla on training systems and companies like Waymo, XPeng, and Nuro on vehicle computing.
“So our system is really quite pervasive because we’re a technology platform provider. That’s the primary difference. There’s no question in our mind that, of the billion cars on the road today, in another 10 years’ time, hundreds of millions of them will have great autonomous capability. This is likely one of the largest, fastest-growing technology industries over the next decade.”
He also emphasized Nvidia’s open approach, saying the company open-sources its models and helps partners train their own systems. “We’re not a self-driving car company. We’re enabling the autonomous industry,” Huang said.
