Speaking at the 2019 AIAA Propulsion & Energy Forum, SpaceX Vice President of Build and Flight Reliability Hans Koenigsmann was significantly more confident that the company is just days or weeks away from wrapping up a serious Crew Dragon failure investigation.

On April 20th, flight-proven Crew Dragon capsule C201 experienced a catastrophic failure mode – largely a surprise to SpaceX – that completely destroyed the vehicle milliseconds prior to a planned static fire test. Given the obvious mortal danger such a failure would have posed to any crew aboard, SpaceX’s plans to conduct its first crewed Crew Dragon launch (Demo-2) in Q3 2019 were thrown out the window. Thankfully, Hans believes that SpaceX is just shy of concluding that investigation, “hopefully” permitting the launch of a critical abort test and Demo-2 before 2019 is out.

More specifically, Koenigsmann noted that SpaceX is currently planning to conduct a critical Crew Dragon in-flight abort (IFA) test in October or November, more or less in line with a recent report from NASASpaceflight.com that the test is targeted for November 11th, 2019. NASASpaceflight also confirmed that SpaceX still plans to fly Falcon 9 booster B1046.3 on the critical test flight, currently the only established plan to launch a thrice-flown booster, a potential first for SpaceX’s reusability program.

SpaceX’s IFA test is a continuation of the company’s suborbital Crew Dragon testing. Back in 2015, SpaceX successfully completed a pad abort test in which a low-fidelity Dragon mockup used its eight SuperDraco abort thrusters to replicate an escape from a rocket failure on the launch pad. SpaceX’s in-flight abort test will – like its namesake indicates – perform a similar test in flight, ensuring that Crew Dragon is able to safely escape from a failing Falcon 9 at Max Q, the point during launch where atmosphere-induced mechanical stress is at its peak.

In theory, demonstrating a successful pad and in-flight (Max Q) abort means that a given spacecraft is able to safely abort at all points during flight – from the pad all the way to orbit. It’s not clear if Crew Dragon is actually designed to be capable of what’s known as an “abort-to-orbit”, but the hardware is likely there if it’s needed.

On July 15th, Hans Koenigsmann and NASA Commercial Crew Program (CCP) manager Kathy Lueders went into significant detail with a preliminary Crew Dragon failure investigation update. They revealed that Crew Dragon’s April 20th explosion was traced to a likely mode, in which a “slug” of Dragon’s liquid oxidizer (nitrogen tetroxide, NTO) leaked and was subsequently smashed into a titanium valve by helium pressurized to several thousand PSI.

Said impact – effectively turning NTO into a bullet – thus created a spark in one or two ways: the titanium debris could have easily created sparks on its own, while NTO is also known to interact in violent and exotic ways with titanium under impact conditions. Either way, the fix is relatively simple (replace the valves and avoid titanium in the NTO pressurization system), but the fact that the design flaw existed in the first place serves as a much larger concern for the entirety of Crew Dragon’s joint SpaceX-NASA design and certification.

Ultimately, Hans seemed much more confident on August 19th than he was a month prior, indicating that the investigation is just shy of wrapping up. Once complete, SpaceX can complete the necessary modifications and get back on the saddle for Crew Dragon’s inaugural crewed launch and next abort test.

Tesla analyst compares Robotaxi to Waymo: ‘The contrast was clear’

“In short, robotaxi felt like a more luxurious service for half the cost and the driving felt more human-like.”

Tesla analyst Jed Dorsheimer of Wall Street firm William Blair compared the company’s Robotaxi platform to Waymo’s driverless ride-sharing program, and had a clear-cut consensus over which option was better in terms of rider experience.

Dorsheimer visited Austin recently to ride in both Tesla’s Robotaxi ride-sharing program and Waymo, which has operated slightly longer than Tesla has in the city. Tesla started rides on June 22, while Waymo opened its vehicles to the public in March.

A Tesla Model Y L Robotaxi is a legitimate $47k Waymo killer

The analyst gave both platforms the opportunity to present themselves, and by the end of it, one was better than the other in terms of rider experience. However, he noted that both platforms gave safe and smooth rides.

Overall, there was a tremendous difference in the feel and environment of each option.

Tesla Robotaxi vs. Waymo

Dorsheimer said that Tesla’s first big advantage was vehicle appearance. Robotaxi uses no external equipment or hardware to operate; just its exterior cameras. Meanwhile, Zoox and Waymo vehicles utilize LiDAR rigs on their vehicles, which made them “stick out like a sore thumb.”

“In contrast, the robotaxis blended in with other Teslas on the road; we felt inconspicuous flowing with the traffic,” he added.

The next big victory went in the way of Robotaxi once again, and it concerned perhaps the most important metric in the ridesharing experience: price.

He continued in the note:

“Confirming our thesis, robotaxi was half the price of Uber, showing its ability to win market share by weaponizing price.”

In terms of overall performance, Dorsheimer noted that both platforms provided safe and “top-notch” experiences. However, there was one distinction between the two and it provided a clear consensus on which was better.

He said:

“In Austin, we took multiple robotaxi and Waymo rides; the contrast was clear. Aside from the visual difference between each pulling up to the curb, the robotaxi was comfortable and familiar, and it felt as though a friendly ghost chauffeur was driving our personal car. Driving was smooth and human-like, recognizing and patiently waiting for pedestrians, switching into less crowded lanes, patiently waiting to execute a safe unprotected turn, and yet, discerning and confident enough to drive through a light that just turned yellow, so as not to slam on the brakes.

Waymo also provided a top-notch service, and we did not encounter any safety concerns, but if we were to be overly critical, it felt more … robotic. In the cabin, you have to listen to an airline-esque preamble on Waymo and safety protocols, and during the ride, you can hear all the various spinning lidar sensors spooling up and down with electronic whizzing sounds.”

Tesla Robotaxi provides an experience that seems to be more catered toward a realistic ride experience. You can control the music, the cabin temperature, and transitioning your travel from one vehicle to the next during a trip will continue your entertainment experience.

If your first trip ends in the middle of a song, your next trip will pick up the music where it left off.

Meanwhile, Waymo’s experience sounds as if it is more focused on rider expectations, and not necessarily providing a ride that felt catered to the occupants. Still, what’s important is that both platforms provided safe rides.

Dorsheimer ended the note with one last tidbit:

“In short, robotaxi felt like a more luxurious service for half the cost and the driving felt more human-like.”

Tesla offers new deal on used inventory that you won’t want to pass up

Tesla opened up lease deals on used Model 3 and Model Y inventory in California and Texas on Tuesday, marking the first time it has launched the option on pre-owned cars.

Tesla is offering a new deal on its used vehicle inventory that consumers looking for a great deal won’t want to pass up.

Traditionally, Tesla has not allowed potential car buyers to lease its used inventory. The only two options were to buy with cash or finance it through Tesla or a bank.

However, with the elimination of the $7,500 new and $4,000 used EV tax credits, Tesla is breaking its own rules and is now offering lease deals on its used vehicle inventory, but only in a couple of states, as of right now.

Tesla is ready with a perfect counter to the end of US EV tax credits

Tesla opened up lease deals on used Model 3 and Model Y inventory in California and Texas on Tuesday, marking the first time it has launched the option on pre-owned cars.

The deals are tremendous and can cost as little as $0 down and under $225 per month for some vehicles.

Tesla also allows customers to buy the vehicle at the end of their lease deal, which enables some really great ways to end up an owner of the car you plan to drive for the next two or three years.

The lease deal also helps Tesla rid itself of older vehicles that might not be of future use to the company. It formerly planned to use leased vehicles in its eventual Robotaxi fleet, but many of the cars in its used inventory have Hardware 3, which is less capable than Hardware 4, which is installed in the new Model 3 and Model Y.

More importantly, Tesla is giving people yet another way to be in the market for a Tesla before the tax credit ends on September 30.

Tesla Model Y L might not come to the U.S., and it’s a missed opportunity

The Model Y L has a variety of big changes that would be advantageous for the U.S. market, including a longer wheelbase, more comfortable seats, a third row that appears to be more spacious than Tesla’s six-seat Model Y that it previously offered, B-Pillar vents for rear passengers, and more.

Tesla’s new Model Y L might not come to the U.S., CEO Elon Musk said this morning.

It’s a missed opportunity, and I’m not the only one who feels this way.

In the past, I have personally written a handful of articles about what Tesla owners have been wanting in the United States: a full-sized SUV, or at least a vehicle that is larger than the Model Y but less of a crossover than the Model X.

Tesla is missing one type of vehicle in its lineup and fans want it fast

The only thing that Tesla has announced that even slightly matches this sort of idea is the Robovan, which is, optimistically, several years off because it lacks a steering wheel and pedals and will require Full Self-Driving to be fully autonomous.

Even if Tesla launches FSD next year, it will take a year or two to figure out manufacturing, go through regulatory hurdles with the EPA, and eventually enter mass production for customers.

The Model Y L has a variety of big changes that would be advantageous for the U.S. market, including a longer wheelbase, more comfortable seats, a third row that appears to be more spacious than Tesla’s six-seat Model Y that it previously offered, B-Pillar vents for rear passengers, and more.

However, Musk said it won’t come to the U.S. until next year, and that it “might not ever, given the advent of self-driving in America.”

To be blunt, I’m not sure if I truly believe that Musk thinks the Model Y L won’t come to the U.S. Some believe he said this to not Osborne Effect Model Y sales here, which seems more likely than anything.

Tesla Model Y L gets disappointingly far production date in the United States

People have been buying the Model Y for two years more than any other car in the world. To act as if many families would not appreciate the extra space seems very strange; a big complaint with the Model Y is that it simply does not fit larger families.

If you have four kids, you’re forced into the Model X, which might be too expensive for some families, as it starts at $79,990.

While Tesla’s focus is undoubtedly on autonomy, it is important to remember that some people still really enjoy the act of driving their cars. Tesla has worked very hard to create a fun and sporty driving experience, especially in the new Model Y. Many consumers, including myself, like to take advantage of that.

Autonomy might eventually take over human driving completely, but in the near term, it does not seem as if that is the case. Even if someone were interested in never driving again, this longer and more spacious Model Y L would be an ideal option for American families that need the room for at least six passengers.

Quite a few big names in the Tesla community share this sentiment:

More than likely, Musk does not want to announce a more attractive option than the current Model Y, as many consumers would likely wait a year or two for the L in an effort to have more space.

In all honesty, I see the Model Y L coming to the United States, as it truly fits the bill as an ideal car for the modern American family.
