Tesla’s success ushers in a new era of electric flight

Published

on

Electric flight may not be as far away as we once thought. In the next decade, aircraft are set to see dramatic changes as companies both large and small work to bring fully electric and hybrid flight to market. Airlines, manufacturers, and startups all seem to be moving towards this goal (see below). The race is clearly on and it will change the way we think about flight.

Yet as it was for the introduction of electric vehicles, the first aircraft is short range and seat just a few passengers. Their applications today are limited but to think the industry will stay in this nascent stage would be a mistake. Successes in these small and short-range aircraft will translate forward into larger and longer-range aircraft. The companies that find success here will emerge as leaders in a new era of electric flight.

On the Market Today:

First, it’s important to appreciate that only recently have small electric powered aircraft gone from concepts to commercial use.

Pipistrel’s Alpha Electro is one of these all-electric aircraft. It’s meant primarily for pilot training and just received its airworthiness certification from the FAA in April 2018, becoming the first in the USA to do so. The Alpha Electro only seats two people and is good for an hour of flight plus reserves. That might not sound like much but it could be disruptive. Pipistrel says the aircraft cuts beginner pilot training costs by as much as 70% while producing zero emissions and low noise.

In China, the Ruixiang RX1E is a similar style trainer sold there commercially. They also have a new, longer-range model that was recently tested, the RX1E-A. With a two-hour flight time the new version doubles its previous capabilities. At this size of aircraft the technology is getting close to parity with comparable gasoline-powered aircraft, like the Cessna 162 which has a flight time of about three hours.

Full parity might be here sooner than you think. Coming small electric aircraft have better specs and more seating, with many nearly ready for certification (pictured below). Pipistrel has their Panthera (top right), which will hold four passengers and will come in options for combustion, hybrid, and all-electric powertrains. There’s also BYE Aerospace in Colorado, which has a four-seater in development and just completed the first test flight of the two-seater Sun Flyer 2 — it has a flight time of 3 hours. Ruixiang also announced they have a 4-seater aircraft in development. The other important consideration is that their initial costs appear to be comparable to combustion options as well.

Looking at these options, some will say that an electric aircraft is an isolated niche and for now, that’s mostly correct. These are small aircraft with limited applications. Yet when the Nissan Leaf and even the Tesla Roaster first came out many believed electric cars were a niche technology too. The range was too short, seating was too small, and costs were too high to realistically consider the technology going mainstream. Now we are in the midst of a market transformation, with automakers pouring billions into their EV programs and countries announcing they are phasing out combustion vehicles.

 

Market Transformation – Near-Term Preproduction:

The next major step for electric flight appears to be in small commuter aircraft. Aircraft that weigh less than 12,500 lbs, carry 5 to 20 passengers and travel up to 750 miles. In addition to regional commuter needs, they may also serve recreational and business purposes. If small aircraft are like the Tesla Roadster then these are like the Model S. They have more seats, longer range, and are made in higher volumes.

The use case of short range regional commuters is almost perfect for electrification. Much of their flight is spent just getting up to altitude, where cruising achieves the greatest efficiency. The time spent cruising however is relatively short and the result is that such regional flights are inherently less efficient than those over greater distances. On the plus side the high operating costs are a great opportunity for electrification. Consider that a turbine engine achieves an efficiency of around 55% at cruising, but on ascent that efficiency can drop by half (~25%). By comparison, an electric motor has efficiencies greater than 95%.

One of the companies working to electrify these regional aircraft is Wright Electric, based out of Los Angeles. They recently announced plans to bring to market a 9-seat electrified aircraft with a range of at least 340 miles. According to their website that would cover the distance of nearly 44% of all flights. The announcement is part of their new partnership with JetEx, a fixed-base operator based in Saudi Arabia with operations in over 30 countries. I recently spoke with Wright Electric’s CEO Jeff Engler about their coming aircraft and where he see’s the industry going. The first thing that surprised me is that their aircraft could be on the market very soon.

“We are certain that the first flight test will take place next year. It could be on the market in just over two years.” – Jeff Engler, CEO of Wright Electric

That means that sometime towards the end of 2020 or beginning of 2021 they could be in their air, operating with paying customers.

Their aircraft is intended for intercity travel and recreational activities Jeff said, but it’s not the end goal. In fact, their approach may be familiar to fans of electric cars.

“Our plan is similar to the Tesla approach, in the sense that they started with the Roadster and then scaled up to larger more mass market vehicles.  Our first plane to market will be a premium aircraft meant to travel short distances with a small number of passengers… perfect for intercity flights and recreational activities like skydiving. This initial program is the springboard for development of larger longer-range aircraft”. – Jeff Engler, CEO of Wright Electric

In regards to the technology Jeff said they are developing the hybrid and all electric powertrains concurrently. He noted that battery advancements will dictate the transition to fully electric flight but in the interim, hybrid solutions will significantly reduce fuel costs, noise, and pollution. With restrained enthusiasm, he was cautiously optimistic about the coming advances in battery technology. Yet battery technology isn’t holding them up.

The beauty of hybrid options is that as batteries improve they can be seamlessly integrated into the design, allowing more of the flight to be electric. For their electric hybrid, Wright Electric likes to use the term “helper motor”. A helper motor can run hard during takeoff and ascent to help bring the aircraft up to altitude, thereby reducing the burden on the combustion engines, improving overall efficiency, and reducing fuel consumption. Once at altitude, the combustion engines can take over, where they operate most efficiently.

Even without being fully electric hybrid aircraft would have surprising benefits to fuel economy, pollution, and noise. Wright Electric has estimated the potential for reducing fuel use by nearly 2/3’s, while fellow electric aircraft startup Zunum Aero indicated 40% to 80% operating savings. Zunum Aero also noted a potential 70% reduction in community noise.

 

More Regional Commuter Aircraft are Coming Too:

Wright electric isn’t the only one working in this space. Other startups are also pushing the industry forward and they’ve partnered with established manufacturers and airlines to help make it happen. It’s similar to the approach Tesla took early on by partnering with established companies like Daimler and Toyota, and even in their recent developments of the Semi.

Zunum Aero is another one of the leaders in the electric aircraft space, based out of the west coast near Seattle. They are developing a 12-seat hybrid-electric, with a targeted range of over 700 miles. First test flights are targeted for 2019 and commercial operation is planned for 2022 (pictured below). Their partners include Boeing and JetBlue and just last week JetSuite announced they would order up to 100 of Zunum’s hybrid aircraft.

Eviation Aircraft is an Israel based company and has great ambitions for their first aircraft named “Alice”. It will be a 9-seat 650 mile aircraft and most importantly “all-electric”. They are targeting brining it to market by 2021. Is all-electric flight on that scale possible by 2021? They’ve said the aircraft will use a 950 kWh battery and just recently signed Kokam as their battery supplier, so they seem to be serious. I hope they make it happen. Alice is gorgeous.

Other Exciting Developments Coming Soon:

In the heavyweight division Airbus, Siemens, and Rolls-Royce have their own partnership, working together on their E-Fan X after the successful small electric E-Fan program. The E-Fan X will be a hybrid demonstrator aircraft based on the 100-seat BAe146. The first test flight is planned for 2020 and they are looking to bring a similarly sized hybrid aircraft to market sometime around 2030. Originally they were going to bring a small electric trainer based on the E-Fan to market in 2017 or 2018 but said the pace of development has set their ambitions upwards. There’s also Airbus’s subsidiary A3 which is working on a small all-electric vertical takeoff and landing aircraft.

E-Fan X

Vertical takeoff and landing aircraft are extremely interesting. They could be the biggest disrupters of all (covered in more detail in a follow up article, part 2). They too seem to be much closer than people think. For flying short distances they don’t actually need massive advancements in battery technology. Norway’s Avinor, their national aircraft operator, seems to indicate the mid 2020’s for practical operation.

Companies like Uber, Lilium, Kittyhawk, A3, and many more are developing electric aircraft capable of vertical takeoff and landing. They look more like flying cars than airplanes and that seems to be the point. These “air-taxis” are meant for hyper-local travel. Something you would hop onto downtown and take to get to across the city or to another nearby city. Lilium is a relatively new startup, founded in 2015, but has already made significant advancements in the space. They’ve already had their first full-scale test flight which is viewable below. Watching it lift off is almost magical.  They brought on former Ferrari designer Frank Stephenson to head their design program and raised $90M to proceed with further development.

Final Thoughts and Intro to Part 2

For fully electric flight a lot depends on batteries, but the technology is already finding applications in short-range, small aircraft. Increasing larger hybrid aircraft are also set to see their application in the real world in just a few years and will yield substantial benefits of their own. These moves should not be discounted. They are a prelude of what’s to come.

At this point, you may be wondering exactly what are the benefits of electric flight. That’s the focus of the second part of this article, coming out soon. They are substantial and will drive the industry forward with haste.

Tesla expands massive safety feature worldwide in latest update

Published

Tesla has expanded the footprint of a massive safety feature worldwide with a recent Software Update labeled as 2026.20.6. The expansion of the “Blind Spot Warning While Parked” feature represents the more widespread availability of the feature, which aims to prevent “dooring.”

Dooring is when a driver or passenger opens a car door into the path of an oncoming road user, usually a cyclist or motorcyclist. It is among the most common types of cycling accidents, the League of American Bicyclists says.

For this reason, Tesla created a feature that warns occupants not to open the door because an object is approaching. The feature will sound a chime, and it will also delay the opening of the door to prevent an incident.

The release notes state (via Not a Tesla App):

“If you attempt to open a door while an approaching object is detected in your blind spot (for example, a bicyclist approaching from behind) a chime sounds, and your door will not open upon initial button press. Wait a short time and press the button a second time to override the warning.”

Tesla initially rolled out this feature back in 2024 with the Model 3 “Highland.” However, it remained with the Model 3 exclusively for over a year; that was until Tesla added it to the Cybertruck this past Spring.

Now, it is making its way to the new Model Y, 2021 and newer Model S, and 2021 or newer Model X.

The prevention of dooring incidents could eliminate many injuries to cyclists, especially in an urban setting. Dooring accounts for 10-20 percent of bike-related crashes in major cities, and over 17,000 dooring-related incidents were treated in the U.S. over the course of a decade. These usually involve fractures, contusions, and head trauma.

Tesla sends production Cybercab with no steering wheel, pedals to on-road testing

Published

on

Credit: Tesla

Tesla confirmed this morning that it has sent the first production units, manufactured with no steering wheel or pedals, to on-road testing in Austin, sharing video of the first rides with no human controls.

The lack of steering wheels and pedals in the Cybercab aligns with Tesla’s self-certification of Robotaxi as Level 4 SAE, a platform it plans to make widespread through internal vehicles and customer-owned cars that will operate and generate revenue for individuals.

The start of these engineering tests is a major signal for Tesla, which plans to bring driverless, wheel-less, and pedal-less Cybercabs to market in the coming months. With production already well underway at Gigafactory Texas, where the Cybercab is built, there is some inclination to believe the first public rides could happen sooner rather than later.

Tesla’s engineering tests will put the Cybercab in real-world scenarios, testing not only the hardware, but more importantly, the software that drives the car around Austin with nobody supervising it within the car.

This is perhaps the biggest part of the internal testing process, especially prior to allowing regular, everyday people to hail the Cybercab for an autonomous ride. These early rides serve as a true benchmark for Tesla: How many rides can it achieve safely? How many miles did it travel consecutively without needing an intervention? What scenarios challenge the Full Self-Driving suite the most?

The proper precautions have already been put into place as well, as Tesla released the First Responders Guide to Cybercab over the weekend, ensuring that emergency services have 24/7 access to Robotaxi Assistance, as well as other boundaries, such as Geofencing features that can be used to redirect autonomous vehicle traffic due to accidents, road closures, construction, or maintenance.

Cybercab seems genuinely close to being added to the Robotaxi fleet in Austin, but Tesla has prioritized safety throughout this entire process. Therefore, we think it could be months before it truly starts giving rides to the public. People have been frustrated with this, but Robotaxi in Austin has a tremendous safety record so far, so the slow rollout has kept people safe and accidents to a minimum.

The most important thing is that Tesla continues to show consistent progress in the Cybercab’s ramp-up toward fleet addition. A few weeks back, we saw the EPA reward the Cybercab a Certificate of Conformity, allowing it to enter the stream of commerce. Then, we saw Tesla add decals, signaling that it was likely about to start testing it publicly. That has now happened.

The next big move will be the announcement of the first rides, so this Summer should be filled with anticipation.

Tesla Phone? Not quite, but close: analyst

Published

For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.

It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.

Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.

The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.

Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.

The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.

SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.

There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.

The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.
