SpaceX fires up first upgraded Starship engine

CEO Elon Musk has implicitly revealed that SpaceX recently conducted the first test of Starship’s new Raptor 2 engine.

Aside from kicking off integrated static fire testing of a refined, operationalized version of Raptor, the first prototype may have briefly become the most powerful engine of its kind ever tested before destroying itself. While not quite as successful as the first static fire campaign of a full-scale Raptor 1 engine, which survived several tests, the first Raptor 2 prototype’s early demise is still a routine part of engine development and is the start of a process that should ultimately produce a Super Heavy booster with 50% more thrust than the next most powerful rocket ever flown.

Prior to last weekend, it’s likely that competitor Blue Origin’s BE-4 – still in development and hoped to one day power ULA’s Vulcan and the company’s own reusable New Glenn – was the most powerful methane/oxygen rocket engine ever tested. BE-4 is designed to produce up to 244 tons (~539,000 lbf) of thrust. On its very first static fire, it appears that SpaceX’s first finished Raptor 2 prototype has narrowly stolen BE-4’s crown, briefly generating main combustion chamber pressures of 321 bar (~4650 psi) and as much as 245 tons (~540,000 lbf) of thrust.

To BE-4’s credit, the engine (at least as far as Blue Origin’s sparse public communications go) didn’t destroy itself after its first full-thrust static fire. Raptor 2 wasn’t so lucky and apparently exploded before completing its first test. There’s also some ambiguity as Blue Origin’s own website pegs BE-4 thrust at “2400 kN (550,000 lbf)” when 2400 kilonewtons is actually equivalent to 539,000 lbf. Regardless, designed to produce up to 230 tons (~510,000 lbf) of thrust in flight, Musk has said that Raptor 2 or V2.0 “is a major improvement in simplification” over Raptor 1, which nominally produces up to 185 tons (~410,000 lbf) of thrust at chamber pressures closer to 270 bar (~3900 psi).

It’s not all that surprising, then, that the first Raptor 2 prototype ever completed exploded when SpaceX pushed it to almost 107% of its maximum rated thrust and main chamber pressure during its first test.

Though impressive, SpaceX has technically pushed Raptor 1 prototypes further – and without failure. Musk later indicated that there was some damage present but a fairly young Raptor 1 engine still made it all the way up to 330 bar (~4800 psi) and spent about 10 seconds at chamber pressures above 320 bar without failure during an August 2020 stress test. Still, had the Raptor 2 prototype also made it to 330 bar, it would have produced around 252 tons (555,000 lbf) of thrust – 12% more than its Raptor 1 predecessor.

Super Heavy boosters will ultimately have 33 more or less identical sea-level-optimized Raptors – 13 Raptor Center (RC) engines with thrust vectoring and 20 Raptor Boost (RB) engines without. (NASASpaceflight – bocachicagal)

According to Musk, the main differences between Raptor 1 and Raptor 2 are “much cleaner” plumbing and wire harnesses and a wider combustion chamber throat, which allows the engine to produce more thrust in roughly the same package at the cost of a slight efficiency loss. Over the last two years, the CEO has mentioned the possibility of a power-optimized Raptor variant with up to 300 tons of thrust but in recent months, Musk says SpaceX has decided to keep the Raptor family as streamlined as possible and opted for just two variants – one with a sea-level nozzle (Raptor Center and Boost) and one with a larger vacuum-optimized nozzle (RVac).

Tesla FSD mocks BMW human driver: Saves pedestrian from near miss

Tesla FSD anticipated a BMW driver’s lane drift before the human behind the wheel could react.

Published

A video posted to r/TeslaFSD this week put a sharp spotlight on Tesla’s Full Self-Driving (FSD) software being able to react to pedestrian intent than an actual human driver behind the wheel. In the Reddit clip, a BMW driver can be seen rolling through a neighborhood street completely unaware of a pedestrian stepping in to cross. At the same time, a Tesla  driving on FSD had already begun slowing down before the pedestrian even began their attempt to cross the street The BMW kept moving, prompting the pedestrian to hop back, while the Tesla came to a stop and provide right-of-way for the human to safely cross.

That gap between what the BMW driver saw and what FSD had already processed is the story. Tesla FSD wasn’t reacting to a person in the street, rather it was reading the signals that a person was about to enter it based on the pedestrian’s movement, trajectory, and their trajectory to telegraph intent.

Tesla’s FSD is now built on an end-to-end neural network trained on billions of real-world miles, learning to interpret subtle human behavioral cues the same way an experienced human driver does instinctively. The difference is consistency. A human driver distracted for two seconds misses what FSD does not.

Reddit commenters in the thread were blunt about the BMW driver’s failure, with several pointing out that the pedestrian was visible well before the crossing. One response put it plainly that the car on FSD saw the situation developing before the human in the other car had registered there was a situation at all.

Tesla has published data showing FSD (Supervised) is 54% safer than a human driver, accumulated across billions of miles driven on the system. Elon Musk has said FSD v14 will outperform human drivers by a factor of two to three, and that v15 has “a shot” at a 10x improvement. Pedestrian safety is where the stakes are highest, and where intent prediction closes the gap fastest. At 30 mph, a car covers roughly 44 feet per second. An extra second of awareness from reading a person’s body language rather than waiting for them to step out is often the difference between a near miss and a fatality.

Tesla Robotaxi gets a small but significant change

In the world of Tesla, where billion-dollar battery breakthroughs and autonomy milestones dominate headlines, a quiet design update can still pack a punch.

In the world of Tesla, where billion-dollar battery breakthroughs and autonomy milestones dominate headlines, a quiet design update can still pack a punch.

Last week in downtown Austin, sharp-eyed observers spotted a subtle but telling evolution on the Cybercab: a new “ROBOTAXI” logo graphic now graces the vehicle’s doors at Tesla’s Autonomy Popup.

What looks at first glance like a minor stylistic choice is, in fact, a deliberate rebranding move that hints at how the company envisions its robotaxi fleet fitting into everyday life.

The updated lettering is bold, graffiti-inspired, and unapologetically street-smart. Rendered in black with dripping white accents and a glowing yellow outline, the font evokes urban energy and playful irreverence.

Gone is the sleek, minimalist typography that defined earlier Cybercab prototypes. In its place is something more human, almost rebellious.

The new logo pops against the Cybercab’s smooth, metallic body, turning the autonomous pod into a rolling piece of public art rather than just another futuristic taxi.

Designers know that fonts are silent brand ambassadors. They shape perception before a single ride is taken. Tesla’s classic sans-serif aesthetic screams precision engineering and Silicon Valley cool.

The new Robotaxi script leans into accessibility and fun, suggesting the vehicle is approachable, not intimidating. For a product meant to ferry strangers through city streets 24/7, that matters. It signals that the robotaxi isn’t reserved for tech elites; it’s for everyone.

The timing is no accident. With regulatory approvals for unsupervised autonomy advancing and Tesla preparing to scale Cybercab production, the company is shifting from prototype showcase to fleet deployment.

A fresh logo helps differentiate the vehicles visually in dense urban environments—crucial for rider recognition and brand recall. It also aligns with Elon Musk’s long-standing ethos: make the future feel exciting, not sterile.

Small changes like this often foreshadow a larger strategy. Tesla has always obsessed over details—door handles, screen interfaces, even the curvature of a steering wheel.

Updating the Robotaxi font reflects the same meticulous care now applied to consumer-facing autonomy. It’s not just paint on metal; it’s a statement that the ride of the future should feel personal, memorable, and undeniably cool.

In an industry racing toward self-driving fleets, Tesla’s willingness to evolve even the smallest visual cues shows confidence. A font won’t launch the robotaxi network, but it might just help millions climb aboard with a smile.

Tesla makes latest announcement on Model S and Model X

The announcement follows Tesla CEO Elon Musk’s statement on the Q4 2025 earnings call in late January. Musk described the decision as an “honorable discharge” for the two vehicles, noting that production would wind down in Q2 2026.

Tesla has officially begun winding down production of its flagship Model S and Model X in the United States, notifying owners via email that the long-running models will soon reach the end of the line.

The email, sent to U.S. customers on March 27, opens with gratitude. “Model S and Model X marked the beginning of the world’s transition to electric transportation,” it reads. “These vehicles also made it possible for Tesla to develop the technology that would move our world toward autonomy.”

It then delivers the news directly: “As we make way for this autonomous future, Model S and Model X production will be ending. If you’d like to bring home a new Model S or Model X, order yours soon from our limited inventory.”

The message closes with a simple thank-you: “Thank you for being part of our journey.”

The announcement follows Tesla CEO Elon Musk’s statement on the Q4 2025 earnings call in late January. Musk described the decision as an “honorable discharge” for the two vehicles, noting that production would wind down in Q2 2026.

The move frees factory floor space at Fremont, California, for next-generation manufacturing, including Optimus humanoid robots and the upcoming Robotaxi platform.

Introduced in 2012 and 2015, respectively, the Model S and Model X were Tesla’s original halo cars. They proved EVs could outperform gasoline luxury vehicles in acceleration, range, and tech features while pioneering over-the-air updates and early autonomy hardware.

Although they never matched the volume of the Model 3 and Model Y, their engineering breakthroughs laid the foundation for the company’s current lineup and full self-driving development.

Early adopters highlighted how the cars convinced them to invest in Tesla stock and the EV movement. Some U.S. owners who had not yet received the note voiced mild frustration, and international customers confirmed the outreach remains U.S.-only for now.

Tesla has not detailed an exact final production date beyond the Q2 2026 target or confirmed immediate replacements. Speculation continues about a possible Cybertruck-derived SUV, but the company’s public focus has shifted squarely to autonomy and robotics.

For buyers still interested in the S or X, the window is closing. Inventory is described as limited, and Tesla’s Korean division has already set a March 31 cutoff for new orders in that market. The email serves as both a farewell and final sales push, an elegant close to a chapter that helped define modern electric driving.
