SpaceX Receives Pentagon Help To Develop New Rocket Engine
SpaceX has been awarded a Pentagon contract for development of its next generation Raptor rocket engine, which is 6 times more powerful than the Merlin engine it uses now.
The U.S. Department of Defense has announced a $33.7 million dollar contract awarded to SpaceX for the development of the Raptor rocket propulsion system prototype as part of the Evolved Expendable Launch Vehicle (EELV) program. The Raptor engine burns a mixture of liquid methane and liquid oxygen, and designed to produce six times the thrust of the Merlin engines SpaceX recently used on its historic mission that saw its first stage rocket land itself back on earth from orbit. Here’s why that’s important to SpaceX.
Currently, virtually all large military satellites launches are done by the United Launch Alliance, a consortium made up of Lockheed Martin and Boeing. In 2013, ULA was awarded a $1.1 billion contract for multiple launches using Lockheed Martin’s Atlas V or Boeing’s Delta IV rockets. SpaceX wants a piece of that pie.
According to Motley Fool, both ULA rockets use RD-180 engines purchased from Russia’s Energomash, which is majority owned by the Russian government. After Russia’s 2014 actions in Crimea, the US slapped economic sanctions on it and Energomash. They in turn decided they would not sell any more rocket engines to ULA. The US Congress responded to that by prohibiting the US military from using any Russian rocket engines to launch its satellites.
But Houston, we have a problem. No rocket engines means no satellite launches. ULA placed its hopes on either Blue Origin or Aerojet Rocketdyne coming up with a new rocket engine to replace the RD-180 it can no longer buy from Energomash, but that process could take 3 or 4 years to complete.
So Congress has relented somewhat. Buried in the more than 1,000 page appropriations bill approved just before Christmas, it gave ULA approval to buy a supply of RD-180s — just enough to keep it in the military launch business for the time being. But clearly, America needs American made rockets for its various space programs going forward.

Enter SpaceX, which received authorization to bid for Pentagon business last year. The next generation Raptor engines will be used to power the upcoming Falcon 9 “heavy lift” and “super heavy lift” rockets. The more powerful Falcon 9 could be used in place of the traditional satellite launching vehicles from Lockheed and Boeing. That would open the door for lucrative government contracts to flow to SpaceX instead of ULA.
There is a lot of money up for grabs launching satellites for the military over next several years. SpaceX has been funding its Raptor engine program out of its own pocket up until now, but under terms of the new contract, the Pentagon will provide $1 in development funding for every $2 invested by SpaceX.
Lockheed and Boeing might be giving way to the Aerospace upstart. SpaceX, like every venture Elon Musk is involved with, will put every ounce of effort into getting to the finish line ahead of everyone else.

Tesla has updated its Robotaxi app so riders can pick which vehicle they want before they book. The latest in-app screens now show two options side by side: the two-seat Cybercab and the four-seat Model Y.
A screenshot circulating Thursday shows the change in practice. In Austin, a rider could choose a gold Cybercab for two people or a Model Y for four. Tesla’s updated description calls Cybercab “our first purpose-built autonomous vehicle,” designed for safety, accessibility, and comfort, and says the lineup is available only through the Robotaxi app.
Tesla has updated their Robotaxi page in the App Store. You’ll be able to select if you want a Cybercab or Model Y Robotaxi.

The distinction is more than cosmetic, and it’s important to note that Robotaxi refers to the platform, while Cybercab refers to a vehicle.
Model Y Robotaxis have carried the service since it opened in Austin in mid-2025 and later expanded to Dallas, Houston, and parts of Florida. Those vehicles are converted production SUVs that still have steering wheels and pedals.
Cybercab is different. It has no driver controls, butterfly doors, a low seat height meant to work with wheelchairs, extra trunk space for assistive devices, and braille on the handles. Tesla has registered dozens of the two-seaters with Texas regulators in the days leading up to its September 3 Austin event.
Giving riders a choice lets Tesla match the vehicle to the trip. Most rides involve one or two people, which is where Cybercab is meant to be cheaper and more efficient to operate. Groups of three or four, or anyone who needs more space, can still request a Model Y.
The same app handles booking, payment, cabin settings, and, on Cybercab, features such as phone-based door opening and in-cabin voice controls.
The update does not mean every city suddenly has both cars available. Cybercab support is listed for Austin first, and the purpose-built fleet is still small compared with the existing Model Y roster. Even so, the app change marks a shift from a single-vehicle pilot to a mixed fleet.
Riders can now choose between the compact, purpose-built robotaxi and the familiar SUV that launched the service.
Tesla Cybercab sightings are broadening far and wide, well outside of downtown Austin, Texas, with autonomy in focus as the company plans to launch the all-electric, two-seater this evening in the Lone Star State.
Tesla is set to launch Cybercab to a small group of people this evening in a dedicated event in Austin, Texas. Public details on the event are relatively slim.
However, Tesla’s focus on Cybercab falls well outside of the downtown Austin area and is expanding well across the United States as things continue to move quickly with the company’s autonomous efforts in 2026. Today, various images of Cybercab fleets in interesting locations have started to circulate.
The most notable is a fleet of at least 20 Cybercabs at Miami International Airport in Florida. Spotted last night, the fleet is expansive and is indicative of a looming release of Cybercabs once regulatory boxes are checked off.
Tesla has already been operating the Robotaxi platform in Miami for several months, but this Cybercab fleet at the airport could be joining the ride-hailing platform as approvals arrive:

Another fleet of Cybercabs was spotted at the Devon, PA showroom just outside of Philadelphia. We have seen several Cybercab units testing around the Philadelphia Metro Area, which is interesting considering Tesla does not have any active Robotaxi geofence in Pennsylvania.

Philadelphia would be an ideal location to test ride-hailing due to its dense tourist population, large, sprawling city layout, and to compete with other ride-hailing companies that operate in the city.
Expansive fleets of Cybercabs will be popping up in and around major cities throughout the rest of the year, if we were betting on it. Tesla has made it obvious that the Cybercab rollout will be aggressive and fast-paced, but within reason. Tesla is still prioritizing safety, so these testing phases will likely go on for some period of time before more members of the public are able to snag a Cybercab for a personal chariot.
The Tesla Model Y L is arguably the most hyped trim of the all-electric crossover, other than the Performance configuration that comes with white-knuckle speed and sports car-level handling.
However, it is not all perfect. Tesla owners in China who took delivery of the Model Y L, denoted with an L to highlight its longer wheelbase, are experiencing what they are referring to as “collapsing” of the rear wheels, as suspension issues appear to be an issue with some of the builds.

• Six-seat long-wheelbase Y. Shanghai. On sale since August 2025
• Owners say the rear tire-to-arch gap shrinks after mileage or a full load. Some cases after about 9,000 km loaded. Others near 30,000 km

The gap between the wheel arch and tire has narrowed to the point that “not even a single finger” could fit, according to a report from Car News China. The failures are not tied to a specific mileage, as one owner said that after just 9,000 kilometers (5,600 miles), they noticed the suspension issue when their car was fully loaded.
Another one had the issue at 30,000 kilometers (18,640 miles) and noticed that the wheel gap shrank to two fingers, so not as drastic as the person who reported a similar issue at 9,000 km.
Tesla Model Y L is gaining momentum in China’s premium segment
Along with the visual recognition of the issue, others are saying the sagging is causing abnormal wear on the inside of the tires. Extra weight and instant torque already provide additional stress on the tires in electric vehicles during normal operation, so it is no surprise that this is another complaint.
There has been no recall issued by Tesla, and the company has not yet publicly acknowledged the issue.
Some are suggesting that owners use a “finger test” to self-diagnose whether there is an issue with the suspension. There should be four fingers between the tire and the wheel well; anything less than that starts to get dicey.
