After years of development, multiple prototypes constructed, and more than 1200 seconds of cumulative static fire testing at durations longer than what is needed to land on Mars, SpaceX propulsion engineers and technicians have successfully built and static-fired the first flight-worthy Raptor for the first time ever.

This is an incredibly important step towards BFR (Starship/Super Heavy) launch operations and is even more directly encouraging for the first integrated hop tests of SpaceX’s Starship prototype (unofficially deemed Starhopper), which could very well be the next host of the pathfinder Raptor engine pictured below.

In the scope of SpaceX’s history designing, building, and optimizing large-scale rocket engines, Raptor’s development likely followed a similar path. While Merlin 1 operates on a dramatically simpler combustion cycle (gas-generator), uses different fuel (kerolox vs. methalox), and is significantly less powerful and efficient than Raptor (as proposed), the workhorse engine went through a range of dramatically different iterations (Merlin 1A, 1B, 1C, and 1D) and is scarcely recognizable when its earliest block is compared to its most recent version. Merlin 1A began as an ablatively cooled 340 kN (76,000 lbf) engine, while the current workhorse (generally known as Merlin 1D Full Thrust, M1D FT) features a regeneratively-cooled nozzle and produces more than 840 kN (190,000 lbf), nearly a threefold improvement in thrust.

Raptor’s subscale prototype – featuring twice the chamber pressure of M1D (200 bar, ~3000 psi) and around the same maximum thrust as Merlin 1D (~1000 kN, 225,000 lbf) – can effectively be examined as the Merlin 1A to the Merlin 1C or 1D-class Raptor that SpaceX’s propulsion team settled on after learning from its smaller predecessors.

Performed on a Raptor-specific test cell at SpaceX’s McGregor, Texas “Rocket Ranch”, this milestone static fire was enabled by what one can safely assume were dozens or hundreds of lessons-learned over the course of two years of prototype engine testing and iterative improvement, working up to a quasi-final design that was shipped to Texas and installed just a few days ago. To kick off the first critical static fire of the pathfinder Raptor hardware, reports from ground observers indicate that SpaceX engineers began with a series of extremely short ‘blip’ tests that appeared perhaps 2-3 seconds from ignition to shutdown.

Starhopper’s one-stop hop spot

The immensely encouraging news of Raptor Block 1’s first successful static fire comes as SpaceX engineers, technicians, and contractors work around the clock to build both the first full-scale Starship prototype (nicknamed Starhopper) and the spartan pad it will lift off from during hop tests. SpaceX’s Boca Chica facilities were marked by a burst of pad-related activity over the last week or two, including the early installation of a range of pipes (some of it insulated for supercool cryogenic methane and oxygen) and the creation of a berm pointing towards the probable location of Starhopper’s simple launch mount and pad. ‘

While the Starship prototype’s three Raptor engines will dramatically outclass Falcon 9’s Grasshopper and F9R development vehicles (also used for hop tests), it’s possible that the same setup – basically a flat (refractory?) concrete pad with GSE (ground support equipment) protected behind a berm and automated water jet turrets around the vicinity – could work for Starhopper, too. For now, the successful static fire of the first post-development Raptor engine marks a massive step towards those initial hop tests and towards the first orbital launches of Starship and Super Heavy a bit further down the road. Stay tuned as SpaceX continues to extensively test Raptor and build out its Boca Chica pad and Starship prototype.

During its Q1 2025 earnings call, Tesla executives hinted at the much-rumored “Model 2” and other next-gen EV designs.

Tesla slightly addressed whether or not it will be pushing forward with the debut of new models later this year in its latest earnings call. The company’s product development executive, Lars Moravy, shared some details about Tesla’s design process and the upcoming affordable models.

“We’re still planning to release models this year. As with all launches, we’re working through, like, the last minute issues that pop up. We’re knocking them down one by one. At this point, I would say that the ramp might be a little slower than we had hoped initially…But there’s nothing that’s blocking us from starting production within the next, within the timeline laid out in the opening remarks.

“And I will say it’s important to emphasize that, as we’ve said all along, the full utilization of our factories is the primary goal for these new products. And so the flexibility of what we can do within the form factor and, you know, the design of it is really limited to what we can do on our existing lines rather than building new ones. But we’ve been targeting the low cost of ownership. Monthly payment is the biggest differentiator for our vehicles, and that’s why we’re focused on bringing these new models with the, you know, the lowest price, to the market, within the constraints I just highlighted.”

In January, Tesla’s Chief Financial Officer Vaibhav Taneja teased several new product introductions for this year. There is at least one product that most Tesla supporters and investors are hoping to see: the company’s affordable vehicles, which have been dubbed by the EV community as the “Model 2” or “Model Q.”

Before Tesla’s Robotaxi event last year, many speculated that the company would also unveil its affordable next-gen vehicle. Gene Munster from Deepwater had expected Tesla to release a stripped-down version of the Model 3 as its affordable vehicle during the Robotaxi event. In the end, Tesla unveiled its Robotaxi vehicle and its Robovan design.

It’s been a while since the Robotaxi event, and Tesla has kept mum about its affordable vehicle. Considering its Q1 2025 performance, TSLA investors look forward to catalysts that could boost the stock.

The “Model 2” has been labeled a potential catalyst for Tesla. As such, TSLA investors and supporters have been itching for news about the new affordable vehicle. The main questions surrounding the “Model 2” revolve around its design and price. Based on Moravy’s statement, the “Model 2’s” design will heavily depend on Tesla’s current assembly lines and supply chain structures.

Tesla owner-investor stands ground after receiving Nazi-themed mail, welcomes new Model Y

The Tesla investor even made it a point to purchase the brightest shade available for her new Model Y.

A TSLA investor has decided to stand her ground after receiving a threatening, Nazi-themed card at her home.

The Tesla investor even welcomed a new Ultra Red Tesla Model Y to show her support for the company.

Responding with a New Tesla

As per 58-year-old Alexandra Merz, an investment analyst and immigration consultant who immigrated from Germany to the United States, she received mail from a Boston address to her home on April 17. Upon opening the letter, she was greeted by an image of the Tesla logo incorporated with a Nazi salute.

Inside the card was a handwritten message which read, “History has its eyes on you.” Merz promptly reported the message to the FBI. In a comment to the New York Post, she stated that she is now even more motivated to support Elon Musk and his ventures.

“This atrocious behavior motivates me even more to stand up for Tesla, Elon, and DOGE,” Merz noted. “I bought our fifth Tesla last Saturday, a beautiful red Model Y, the best car out there. And it drives itself.”

An Unfortunate Trend

In previous comments, Merz expressed her disdain for the ongoing attacks against Tesla and Musk. “Tesla is employing more than 140,000 employees worldwide, building the most American cars in the U.S., and building the European Model Ys in Berlin. I often wonder whether these protesters have thought through what they are doing,” she stated.

Elon Musk himself admitted to the disturbing trend during Tesla’s Q1 2025 earnings call, stating that “there’s been some blowback for the time that I’ve been spending in government with the Department of Government Efficiency or DOGE.” The CEO also stated that he would soon be stepping back from DOGE’s everyday operations and focusing more of his time on Tesla.

U.S. President Donald Trump also addressed the ongoing attacks on Teslas in a comment about Musk’s impeding step back from DOGE. As per Trump, people against Musk are taking out their frustrations on Tesla and its owners, which is unfair. He also described the people behind the attacks on Tesla as “sick.”

Trump’s tariff exemptions for car parts bring mixed relief to automakers

U.S. President Donald Trump is expected to grant tariff exemptions for car parts, offering partial relief to automakers amid intense industry lobbying. Trump’s tariff exemptions aim to ease the burden of trade policies disrupting the auto sector.

The expected tariff exemptions will spare car parts from duties targeting Chinese imports and those on steel and aluminum, per two sources familiar with the matter. Sources called the strategy a “destacking” of tariffs. The 25% tariff on foreign-made cars, already in effect, and a 25% duty on imported car parts, set for May 3, will remain.

The Center for Automotive Research estimated that Trump’s 25% tariffs on automotive imports will inflate automakers’ costs by $108 billion in 2025, threatening profitability and supply chains. Automakers are clambering to comply with Trump’s auto tariffs while maintaining car prices, or at least keeping prices reasonable. However, the tariffs threaten to unravel the auto industry, affecting automakers, parts suppliers, and long-established supply chains.

Tesla has quickly adjusted to Trump’s auto tariffs, suspending plans to ship components from China for its Cybercab and Semi electric trucks to the U.S. Similarly, Ford halted shipments of select vehicles to China, facing retaliatory tariffs as high as 150%, which have severely impacted its export strategy.

The partial exemptions offer a reprieve for automakers reliant on global supply chains, but the persistent 25% tariffs on cars and auto parts continue to challenge cost structures. As U.S. automakers navigate these trade hurdles, the exemptions could stabilize some operations, though rising car prices and supply chain disruptions remain significant concerns for the industry’s outlook in 2025.
