SpaceX CEO Elon Musk says he has been working through the holidays at the company’s Boca Chica facilities to get Starship’s “most difficult part” ready for the next-generation spacecraft’s next prototype and flight tests.

Known as tank domes or bulkheads, Musk says that the hardware is the most difficult part of building and assembly Starship’s primary structure, referring to the steel engine section, tanks, and pointed nose that comprise most of the spaceship’s body. Starship’s primary structure must stand up to the rigors of all aspects of flight, including highly-pressurized propellant tanks, extreme G-forces during launches, orbital reentry, and more.

It was never officially determined whether the failure was intentional or not but during the first Starship prototype’s (Mk1) last test campaign, the vehicle experience an overpressure event while being filled with liquid oxygen or nitrogen. Localized to the weld connecting the upper tank dome to Starship’s cylindrical tank section, the dome essentially sheared off at the weld and launched hundreds of feet into the air, sending a shockwave through the vehicle that crumpled many of its steel structures as if they were aluminum foil.

It’s likely that Starship Mk1’s failure was an intentional overpressure event, meaning that SpaceX may have purposely pressed the vehicle’s tanks beyond their design limits to determine how structurally sound they were. What is less clear is whether the rocket burst before or after reaching its theoretical design limit.

For reference, SpaceX’s Falcon 9 rocket operates with its fuel and oxygen tanks pressurized to about 50 psi (3.5 atm) with localized pressures likely doubling or tripling near the bottom of both tanks during the first minute or two of launch. Some amateur back-of-the-envelope calculations from videos of Starship Mk1’s burst event suggest that it was pressurized to at least 60-75 psi (4-5 atm) at its upper tank dome, meaning that the pressure on its two lower domes and tank walls would have been even higher. If correct, those unofficial figures mean that Mk1 actually performed quite well considering the ramshackle facilities and unprecedentedly spartan methods used to fabricate and assemble it.

As such, Musk likely considers Starship’s tank domes the “most difficult part of [its] primary structure” in large part because of how difficult it is to make giant propellant tank domes simultaneously light and strong. Musk has previously implied that Starship Mk1 was more 200 tons (450,000 lb) empty while the ultimate goal for the spacecraft’s empty weight is closer to 120 tons, and a large portion of that weight savings will likely have to come from making its tank domes as light as possible.

In line with that educated speculation, the last month or so of SpaceX’s Starship work in Boca Chica, Texas has been marked by a distinct focus on building tank domes. In fact, Musk himself tweeted that he had worked all night with SpaceX engineers in Boca Chica in a bid to get dome production ready for Starship’s Mk3 prototype, the first Super Heavy hardware, and many more rockets to come.

Prior to Musk’s tweet, a Starship tank dome was actually shipped all the way from Florida to Texas and arrived earlier this month. Meanwhile, technicians have been briskly building up an additional dome using what appears to be a different method of integration involving new parts. SpaceX is currently attempting to weld Starship’s tank domes together from several dozen pre-formed sheets of stainless steel.

The sheets of steel assembled into the dome Musk showed on December 27th likely arrived in Boca Chica on December 13th, implying that SpaceX has managed to complete the majority of the first dome prototype – using a new process – in barely two weeks.

After SpaceX lifted the partially-completed dome off one of its custom assembly jigs, workers almost instantly began staging new sections of steel, beginning the process of integrating yet another tank dome – now likely the fourth on-site in Boca Chica. Meanwhile, at a nearby section of SpaceX’s Boca Chica production facilities, yet another dome was visible on the 28th. In short, SpaceX should soon have more than enough tank domes to complete the next Starship prototype – said to be a significantly improved and refined design compared to Mk1.

Known as Starship Mk3 (or Starship SN01), Musk says that the rocket – currently just a miscellaneous collection of separate parts – could (“hopefully”) be ready for its first flight as soon as February or March 2020.

Tesla Semi lines up for $165M in California incentives ahead of mass production

The update was initially reported by The Los Angeles Times.

Tesla is reportedly positioned to receive roughly $165 million in California clean-truck incentives for its Semi.

The update was initially reported by The Los Angeles Times.

As per the Times, the Tesla Semi’s funding will come from California’s Hybrid and Zero-Emission Truck and Bus Incentive Project (HVIP), which was designed to accelerate the adoption of cleaner medium- and heavy-duty vehicles. Since its launch in 2009, the HVIP has distributed more than $1.6 billion to support zero-emission trucks and buses across the state.

In recent funding rounds, nearly 1,000 HVIP vouchers were provisionally reserved for the Tesla Semi, giving Tesla a far larger share of available funding than any other automaker. An analysis by the Times found that even after revisions to public data, Tesla still accounts for about $165 million in incentives. The next-largest recipient, Canadian bus manufacturer New Flyer, received roughly $68 million.

This is quite unsurprising, however, considering that the Tesla Semi does not have a lot of competition in the zero-emissions trucking segment.

To qualify for HVIP funding, vehicles must be approved by the California Air Resources Board and listed in the program catalog, as noted in an electrive report. When the Tesla Semi voucher applications were submitted, public certification records only showed eligibility for the 2024 model year, with later model years not yet listed.

State officials have stated that certification details often involve confidential business information and that funding will only be paid once vehicles are fully approved and delivered. Still, the first-come, first-served nature of HVIP means large voucher reservations can effectively crowd out competing electric trucks. Incentive amounts for the Semi reportedly ranged from about $84,000 to as much as $351,000 per vehicle after data adjustments. 

Unveiled in 2017, the Tesla Semi has seen limited deliveries so far, though CEO Elon Musk has recently reiterated that the Class 8 all-electric truck will enter mass production this year.

Tesla reveals major info about the Semi as it heads toward ‘mass production’

Some information, like trim levels and their specs were not revealed by Tesla, but now that the Semi is headed toward mass production this year, the company finally revealed those specifics.

Tesla has revealed some major information about the all-electric Semi as it heads toward “mass production,” according to CEO Elon Musk.

The Semi has been working toward a wider production phase after several years of development, pilot programs, and the construction of a dedicated production facility that is specifically catered to the manufacturing of the vehicle.

However, some information, like trim levels and their specs were not revealed by Tesla, but now that the Semi is headed toward mass production this year, the company finally revealed those specifics.

Tesla Semi undergoes major redesign as dedicated factory preps for deliveries

Tesla plans to build a Standard Range and Long Range Trim level of the Semi, and while the range is noted in the company’s newly-released spec list, there is no indication of what battery size will be equipped by them. However, there is a notable weight difference between the two of roughly 3,000 lbs, and the Long Range configuration has a lightning-fast peak charging speed of 1.2 MW.

This information is not available for the Standard Range quite yet.

The spec list is as follows:

  • Standard Range:
    • 325 miles of range (at 82,000 lbs gross combination weight
    • Curb Weight: <20,000
    •  Energy Consumption: 1.7 kWh per mile
    • Powertrain: 3 independent motors on rear axles
    • Charging: Up to 60% of range in 30 minutes
    • Charge Type: MCS 3.2
    • Drive Power: Up to 800 kW
    • ePTO (Electric Power Take Off): Up to 25 kW
  • Long Range:
    • Range: 500 miles (at 82,000 lbs gross combination weight)
    • Curb Weight: 23,000 lbs
    • Energy Consumption: 1.7 kWh per mile
    • Powertrain: 3 independent motors on rear axles
    • Charging: Up to 60% of range in 30 minutes
    • Charge Type: MCS 3.2
    • Peak charging speed: 1.2MW (1,200kW)
    • Drive Power: Up to 800 kW
    • ePTO (Electric Power Take Off): Up to 25 kW

It is important to keep in mind that the Semi is currently spec’d for local runs, and Tesla has not yet released or developed a sleeper cabin that would be more suitable for longer trips, cross-country hauls, and overnight travel.

Instead, the vehicle will be initially used for regional deliveries, as it has in the pilot programs for Pepsi Co. and Frito-Lay for the past several years.

It will enter mass production this year, Musk confirmed on X over the weekend.

Now that the company’s dedicated Semi production facility in Sparks, Nevada, is standing, the timeline seems much more realistic as the vehicle has had its mass manufacturing date adjusted on several occasions.

Ferrari Luce EV: Italian supercar maker reveals interior and interface design

Published

on

Ferrari, the Italian supercar maker, has revealed the name, interior, and interface design of its first-ever electric vehicle project, the Luce, initiating a new chapter in the rich history of the company’s automotive books.

This is the first time Ferrari has revealed such intimate details regarding its introductory EV offering, which has been in the realm of possibility for several years.

As more companies continue to take on EV projects, and some recede from them, supercar companies like Ferrari and Lamborghini are preparing to offer electric powertrains, offering super-fast performance and a new era of speed and acceleration.

Luce – a New Chapter in Ferrari

The company said that the name Luce is “more than a name. It is a vision.” Instead of looking at its first EV offering as a means to enter a new era of design, engineering, and imagination. The company did not want to compromise any of its reputation, high standards, or performance with this new project. It sees it as simply a page turn, and not the closing of a book:

“This new naming strategy reflects how the Ferrari Luce marks a significant addition to the Prancing Horse’s line-up, embodying the seamless expression of tradition and innovation. With its cutting-edge technology, unique design, and best-in-class driving thrills, it unites Ferrari’s racing heritage, the timeless spirit of its sports cars, and the evolving reality of contemporary lifestyles. It testifies to Ferrari’s determination to go beyond expectations: to imagine the future, and to dare. Because leading means illuminating the path ahead – and Luce embodies that mindset.”

Ferrari Luce Design

Ferrari collaborated with LoveFrom, a creative collective founded by Sir Jony Ive and Marc Newson. The pair has been working with Ferrari for five years on the Luce design; everything from materials, ergonomics, interface, and user experience has been designed by the two entities.

The big focus with the interior was to offer “a first, tangible insight into the design philosophy…where innovation meets craftsmanship and cutting-edge design. The team focused on perfecting and refining every solution to its purest form — not to reinvent what already works, but to create a new, carefully considered expression of Ferrari.”

The company also said:

“Ultimately, the design of the Ferrari Luce’s interior is a synthesis of meticulous craftsmanship, respect for tradition, and thoughtful innovation. It offers a new choice for Ferrari enthusiasts – one that honours the past while embracing the future, and exemplifies the brand’s enduring commitment to quality, performance, and cultural significance.”

The appearance of the elements that make up the interior are both an ode to past designs, like the steering wheel, which is a reinterpretation of the iconic 1950s and 1960s wooden three-spoke Nardi wheel, and fresh, new designs, which aim to show the innovation Ferrari is adopting with this new project.

Interior Highlights

Steering Wheel

The Ferrari Luce is a shout-out to the Nardi wheel from the 1950s and 60s. It is constructed of 100% recycled aluminum, and the alloy was developed specifically for the vehicle to “ensure mechanical resistance and a superb surface quality for the anodisation process.”

It features two analogue control modules, ensuring both functionality and clarity, Ferrari said. The carmaker drew inspiration from Formula One single-seaters, and every button has been developed to provide “the most harmonious combination of mechanical and acoustic feedback based on more than 20 evaluation tests with Ferrari test drivers.”

Instrument Cluster and Displays

There are three displays in the Luce — a driver binnacle, control panel, and rear control panel, which have all been “meticulously designed for clarity and purpose.”

The binnacle moves with the steering wheel and is optimized for the driver’s view of the instrumentation and supporting driver performance.

Displays are crafted by Samsung and were specifically designed for the car, using a “world first – three large cutouts strategically reveal the information generated by a second display behind the top panel, creating a fascinating visual depth that captures the eye.”

Samsung Display engineers created an ultra-light, ultra-thin OLED panel for the vehicle.

Pricing is still what remains a mystery within the Luce project. Past reports have speculated that the price could be at least €500,000, or $535,000.
