SpaceX has reportedly swapped a “suspect” Raptor engine installed on Starship serial number 10 (SN10) in record time, setting the company up for what appeared to be an excellent static fire just 48 hours after the first test.

In a February 24th tweet, CEO Elon Musk told followers that “one of [SN10’s three Raptor] engines is suspect, so we’re swapping it out.” Engine swap-outs have been a regular procedure for SpaceX’s Starship team as the company continually pushes the envelope of both Starship and Raptor prototype fidelity and implement major design changes and upgrades. Of the five Starship prototypes (including Starhopper) with intentional flights under their belts, all required at least one engine replacement before being cleared to launch.

Within ~18 hours of Tuesday’s “suspect” Starship SN10 static fire, SpaceX dispatched a replacement Raptor down the road from a nearby storage site. Within ~12 hours, the faulty engine had been removed and a backup engine installed in its place. Another ~12 hours after that, SpaceX teams cleared the launch pad for Starship SN10 to attempt a second static fire and (hopefully) qualify the rocket for flight.

Starship SN10 – set to be the sixth prototype to fly – is now part of that elite but buggy group of flightworthy test articles. For the most part, that bugginess is all according to plan: SpaceX’s ability to move and react with extreme speed is what allows the company to make such rapid progress and begin test flights as early in the development process as it does. That speed of action includes responding to the inevitable bugs that crop up while testing cutting-edge rocket prototypes.

Case in point, after Tuesday’s 5pm CST static fire, it took SpaceX less than 48 hours to pore through the test’s data, conclude that one of SN10’s three Raptor engines was “suspect,” select a replacement engine, remove the faulty engine, install that replacement, and fire up Starship SN10 a second time. Even SpaceX’s world-class reusable Falcon rockets would have a hard time challenging that engine swap turnaround. Taking a broader look at the lay of the land, NASA’s SLS rocket booster – outfitted with four former Space Shuttle engines – will reportedly require more than three weeks for teams to swap out a faulty valve in one of those four engines.

The first SLS Core Stage suffered an early abort during its first static fire test in mid January. As of publishing, NASA is now working towards a second static fire attempt in mid March – two full months later. By all appearances, SpaceX turned Starship SN10 around in 48 hours, performing what looked like a full-duration, nominal three-engine static fire on February 25th. Unlike February 23rd’s static fire, Starship exhibited no signs of an abort immediately after the test, whereas SN10 began large depressurization venting the second its Raptors shut down on Tuesday.

Unfortunately, everything will remain uncertain until SpaceX official confirms its plans, but Starship SN10 should be fully cleared for a launch attempt as early as Monday, March 1st if a data review of its Thursday static fire raises no red flags. Stay tuned for updates as SpaceX prepares to find out if the third time really is the charm.

During the Q4 FY 2020 earnings call, Elon Musk remarked that the Tesla Model X refresh would be released a little later than the Model S refresh, which would be delivered sometime in February. If recent sightings around Tesla’s electric vehicle plant in California are any indication, however, it appears that the flagship SUV may be heading for customer deliveries soon as well, perhaps even around the same time as its large sedan sibling. 

A recent drive from electric vehicle advocate The Kilowatts around Tesla’s Fremont Factory has revealed that the electric car maker is already producing some Model X refresh units. While it remains to be seen if the vehicles themselves are release candidates or if they are already greenlit for customer deliveries, the presence of the flagship SUV in the EV plant’s holding lots bodes well for the Model X refresh’s release. 

Like the new Model S sedans sighted around the Fremont Factory recently, the Model X refresh in the facility’s holding lots were fitted with blacked-out trim. The Model X refresh units also seem to be equipped with Tesla’s new 20″ Cyberstream Wheels, which come included with every order of the flagship SUV. 

The fact that Tesla has started building the refreshed Model X is quite interesting, especially considering the vehicle’s complexity. The Model X is notorious among Tesla’s entire lineup as the most difficult EV to produce, with CEO Elon Musk admitting that the premium SUV was the result of hubris. Musk has also called the Model X as the Faberge Egg of cars, in the way that there will probably be no other vehicle like it.

The presence of the Model X refresh units in Fremont’s holding lots potentially highlights a recent point that Elon Musk recently shared in an email to Tesla employees. In his message, Musk noted that the retooling of the Model S and Model X production lines is almost done, with Tesla aiming for maximum production in the second quarter. The CEO added that there is a high demand for the flagship vehicles, likely due to renewed interest resulting from the recently-introduced refresh.

A leaked Elon Musk email recently revealed that parts supply issues gave Tesla the opportunity to bring the Fremont Factory’s production down. There were rumors that Tesla shut down production lines in Fremont before the email’s leak, which may have worried people who were closely watching the company.

The recently leaked Elon Musk email provided some much-needed context for the shutdown in Fremont’s production lines. The Tesla CEO didn’t seem too worried about the short pause in production and saw it more as an opportunity rather than a hindrance.

In his email, Musk wrote that Fremont’s momentary pause in production gave Tesla the chance to upgrade equipment and do maintenance work.

“Fremont production is back up and running as of yesterday and will spool up rapidly to full 3/Y production over the next several days,” he wrote.

He also informed Tesla employees that retooling in the Model S and Model X production lines was nearly complete. “…and will be aiming for max production next quarter,” he announced.

He shared that there was high demand for the Model S and Model X refresh. Due to the high demand, Musk aims to have two shifts for the Models S/X production line. He also asked employees to recommend friends for recruiting.

Deliveries for the Plaid Model S are expected to start this quarter. During the last earnings call, Musk estimated that deliveries would start this month. There have been several Plaid Model S vehicles spotted outside Fremont already. Given that there are only a few days left before this month ends, deliveries may start in March instead.

If Tesla can ramp production and start deliveries before the end of March, the company may have excellent first-quarter results to share at the next earnings call and start the second quarter on firm footing.

Michelin announced the launch of its Pilot Sport EV tire, which was specifically created and designed for high-performance electric cars. The Pilot Sport EV tire will probably be popular among Tesla owners who love to take their vehicles to the track.

According to Michelin, the Pilot Sport EVs feature optimal grip on both dry and wet roads, and they have great resistance to wear. The Pilot Sport EV tire’s robust design might be notable to owners who love the track, considering that high-performance electric cars like the Tesla Model 3 Performance tend to wear out their tires quickly if they are driven extremely hard.

The Pilot Sport EV tires are also optimized with low rolling resistance, enabling range improvements of up to 37 miles. Michelin did an internal study last year with an electric car weighing 2,151 kg (4,700 lbs) that resulted in the vehicle traveling 60 km further when it was equipped with the Pilot Sport EV tires.

Michelin noted that the Pilot Sport EVs are also designed to have 20% less road noise, thanks to some custom-developed polyurethane foam that muffles sounds. Road noise is a notable issue for EVs, which may be why companies like DSP Concepts work hard to bring noise cancellation technology into the cabin. Tesla’s Model S and Model X refresh were specifically listed with noise cancellation technologies when announced.

Michelin’s Pilot Sport EV tires will also be eco-friendly. The tire manufacturing company has pledged to neutralize the CO2 emissions associated with tire production and transport to its point of sale. Michelin’s efforts would make the EV-centric tires just as friendly to the environment as the high-performance electric vehicles they support.

The Pilot Sport EV tires are already available in China and are expected to be available in Europe and North America by Q3 2021. Customers can choose between 16 sizes for 18 to 22-inch rims.
