In his latest round of SpaceX-related tweets, CEO Elon Musk says that the company has plans to boost Raptor’s performance by at least 15% and the number of those engines installed on Starship by 50%.

Those updated goals came hand in hand with significant changes to the design and operation of both Starship and its Super Heavy booster, which at one point was expected to utilize a “Boost” variant of Raptor that would trade thrust vector control (TVC; i.e. gimballing) and a wide throttle range for far greater thrust. At least according to Musk’s latest account, that substantially different “Raptor Boost” variant is now no more.

On July 3rd, NASASpaceflight forum member and photographer BocaChicaGal captured photos of SpaceX delivering three new Raptor engines to its Boca Chica Starship factory. Two of those engines (RB3 and RB4) featured Raptor Boost labels and were likely the first engines of their kind to complete qualification testing in McGregor, Texas. As of their arrival in South Texas, it was assumed that Raptor Boost still represented a variant of the engine with almost 50% more thrust at the cost of gimbal and throttle authority.

However, Musk himself replied to some of the resulting tweets later that evening, revealing that Super Heavy’s outer ring of up to 20 “Raptor Boost” engines would indeed have no ability to gimbal but would still be able to throttle.

Later the same day, the SpaceX CEO clarified further, stating that the company now plans to upgrade Raptor’s existing design to boost engine thrust to ~230 tons (~510,000 lbf) while still maintaining a wide throttle range and optional thrust vector control. With such an engine, “all Raptors on [a Super Heavy] booster, whether fixed or gimbaling, would be the same.” The only unique aspect of “Raptor Boost,” then, would be their installation around the inner ‘ring’ of Super Heavy’s skirt and their resulting lack of gimbal authority.

It’s somewhat unclear, then, why two of the engines SpaceX delivered on July 3rd were labeled “RB#” and one explicitly outfitted with a name tag reading “Hello, my name is Boost.” Notably, a quick side-by-side comparison enabled by those photos strongly implies that Raptor Booster engine 3 (RB3) and Raptor 79 (R79) are virtually identical aside from RB3’s rerouted plumbing and unique mounting hardpoints. In other words, barring surprises, the “boost” nomenclature appears to be more vestigial than anything.

Ultimately, as Musk notes, if SpaceX manages to boost “Raptor 2” to 230 tons of thrust, a Super Heavy booster with 33 mostly identical engines would have a peak liftoff thrust around 7600 tons (~16.8 million lbf), translating to a thrust to weight ratio of more than 1.5. For a large rocket with liquid propulsion only, a TWR greater than 1.5 is very respectable and improves acceleration off the launch pad, reduces gravity losses in the first few minutes of ascent, and thus boosts overall efficiency.

Already, Musk’s implication that 33 engines could ultimately be installed on Super Heavy is a departure from comments the CEO made barely a month ago when he revealed a base increase from 28 to 29 engines with the possibility of expanding to 32 down the road. Also new is the implication that SpaceX is considering adding three more vacuum-optimized engines to Starship’s six planned Raptors, leaving ships with six Raptor Vacuum (RVac) engines and three sea level-optimized engines (the same variant on Super Heavy).

Musk says that SpaceX has yet to decide if Raptor Vacuum will be commonized with Raptor 2, boosting its thrust, or if greater efficiency will be pursued instead. Regardless, even with six 200-ton-thrust RVacs and three Raptor 2s, Starship would produce upwards of 2000 tons of thrust in vacuum, creating an upper stage with almost as much thrust as Falcon Heavy and a fully-fueled thrust to weight ratio of ~1.7 – even better than Super Heavy.

Tesla rival Xpeng’s flying car unit has been rebranded as Aridge, and it recently showed off its new flying car concept that has 500 kilometers (310 miles) of range and can travel at speeds of up to 360 kilometers per hour (224 MPH).

In Dubai earlier this week, Abridge showed off its new High-Speed Long-Range Full Tilt-Rotor Flying Car, which it aims to release in the Middle East as soon as 2027.

CEO and Vice President Du Chao said at the event on Monday that Aridge will pioneer new categories of flying cars under the brand, which was formerly called Aeroht. Aridge will focus on delivering cutting-edge, low-altitude products, aiming to make these types of aircraft more popular in the coming years.

At the event in Dubai, Aridge showcased its Land Aircraft Carrier, which completed the first overseas public demonstration of a manned flight for the modular flying car, CNEV Post reported.

So far, it has already accumulated 7,000 cumulative orders for the vehicle. 600 of them are going to the United Arab Emirates’ Ali & Sons Group, Qatar’s Almana Group, Kuwait’s AlSayer, and the Chinese General Chamber of Commerce UAE.

It was not the only thing Aridge showcased at the event, either. It also has a long-range hybrid flying car called the A868. This is the concept with the 500-kilometer (310-mile) range rating and the 360 kilometers per hour (224 MPH) top speed.

The A868 will target long-distance travel needs for consumers and will work alongside the Land Aircraft Carrier to build diversified low-altitude application scenarios that would be beneficial from a civilian and commercial standpoint.

The vehicles will be built at a new facility that was completed at the end of September, which is located in Guangzhou. It will be able to build 10,000 units with full-scale production and delivery scheduled to take off in 2026.

Tesla ramps production of its ‘new’ models at Giga Texas

The vehicles are being built at Tesla Gigafactory Texas in Austin, and there are plenty of units being built at the factory, based on a recent flyover by drone operator and plant observer Joe Tegtmeyer.

Tesla is ramping up production of its ‘new’ Model Y Standard at Gigafactory Texas just over a week after it first announced the vehicle on October 7.

Earlier this month, Tesla launched the Tesla Model 3 and Model Y “Standard,” their release of what it calls its affordable models. They are priced under $40,000, and although there was some noise surrounding the skepticism that they’re actually “affordable,” it appears things have been moving in the right direction.

The vehicles are being built at Tesla Gigafactory Texas in Austin, and there are plenty of units being built at the factory, based on a recent flyover by drone operator and plant observer Joe Tegtmeyer:

The new Standard Tesla models are technically the company’s response to losing the $7,500 EV tax credit, which significantly impacts any company manufacturing electric vehicles.

However, it seems the loss of the credit is impacting others much more than it is Tesla.

As General Motors and Ford are scaling back their EV efforts because it is beginning to hurt their checkbooks, Tesla is moving forward with its roadmap to catalyze annual growth from a delivery perspective. While GM, Ford, and Stellantis are all known for their vehicles, Tesla is known for its prowess as a car company, an AI company, and a Robotics entity.

Elon Musk was right all along about Tesla’s rivals and EV subsidies

Tesla should have other vehicles coming in the next few years, especially as the Cybercab is evidently moving along with its preliminary processes, like crash testing and overall operational assessment.

It has been spotted at the Fremont Factory several times over the past couple of weeks, hinting that the vehicle could begin production sometime next year.

Tesla set to be impacted greatly in one of its strongest markets

Tesla could be greatly impacted in one of its strongest markets as the government is ready to eliminate a main subsidy for electric vehicles over the next two years.

In Norway, EV concentrations are among the strongest in the world, with over 98 percent of all new cars sold in September being electric powertrains. This has been a long-standing trend in the Nordic region, as countries like Iceland and Sweden are also highly inclined to buy EVs.

However, the Norwegian government is ready to abandon a subsidy program it has in place, as it has effectively achieved what it set out to do: turn consumers to sustainability.

This week, Norway’s Finance Minister, Jens Stoltenberg, said it is time to consider phasing out the benefits that are given to those consumers who choose to buy an EV.

Stoltenberg said this week (via Reuters):

“We have had a goal that all new passenger cars should be electric by 2025, and … we can say that the goal has been achieved. Therefore, the time is ripe to phase out the benefits.”

EV subsidies in Norway include reduced value-added tax (VAT) on cheaper models, lower road and toll fees, and even free parking in some areas.

The government also launched programs that would reduce taxes for companies and fleets. Individuals are also exempt from the annual circulation tax and fuel-related taxes.

In 2026, changes will already be made. Norway will lower its EV tax exemption to any vehicle priced at over 300,000 crowns ($29,789.40), down from the current 500,000, which equates to about $49,500.

This would eliminate each of the Tesla Model Y’s trim levels from tax exemption status. In 2027, the VAT exemptions will be completely removed. Not a single EV on the market will be able to help owners escape from tax-exempt status.

There is some pushback on the potential loss of subsidies and benefits, and some groups believe that the loss of the programs will regress the progress EVs have made.

Christina Bu, head of the Norwegian EV Association, said:

“I worry that sudden and major changes will make more people choose fossil-fuel cars again, and I think everyone agrees that we don’t want to go back there.”
