Advanced air mobility startup Overair is celebrating a significant milestone this morning, completing its first full-scale Butterfly eVTOL prototype ahead of flight testing in 2024. With its unique rotor design compared to many other eVTOLs, Overair’s electric aircraft looks to achieve commercial operations in multiple countries.

Overair is an advanced air mobility (AAM) specialist based in Santa Ana, California, that was spun out of Karem Aircraft in 2020. In three short years, the Overair team has combined decades of aerospace experience into a flagship electric vertical takeoff and landing (eVTOL) airfcraft called the Butterfly.

The Butterfly’s current design enables transporting up to five passengers plus one pilot, or 1,100 pounds of cargo. The eVTOL prototype has been advertised to achieve speeds of 200 mph, traveling approximately 100 miles on a single charge. Up until this point however, Overair had yet to build a full-scale version of the Butterfly.

That process really gained momentum in the summer of 2022, when Overair announced $145 million in funding to help get its Butterfly eVTOL into the prototyping stage ahead of actual flight testing.

Since then, we’ve seen the startup ink a letter of intent to sell up to 20 Butterfly eVTOLs in South Korea and two additional memoranda of understanding in Texas to help bring commercial EV operations to the northern region of the state.

Today, Overair has shared a vital progress update as it enters 2024 with eVTOL prototype testing on the schedule.

Overair eVTOL prototype complete, flight testing to begin

Following propulsion testing in 2022, Overair has officially assembled its first full-scale Butteryfly eVTOL prototype. When flight testing inevitably begins, Overair will finally take to the skies with two novel aviation technologies: Optimum Speed Tilt Rotors (OSTRs) and Individual Blade Control (IBC)Technology.

The company states that initial tests will validate the flagship eVTOL’s propulsion systems, flight control mechanics, safety features, and operational efficiency. The overall noise of the eVTOL (a huge factor in the future success of the segment) will also be assessed as Overair targets a noise level of 55 decibels. Overair CEO Ben Tigner spoke to the company milestone:

Assembling our first full-scale prototype vehicle marks the culmination of years of industry expertise, meticulous development planning, innovative engineering, and the hard work of the entire Overair team. This seamless transition from propulsion testing to a full-scale prototype underscores our dedication to redefining the eVTOL landscape with safer, quieter, and more reliable aircraft.

As the first eVTOL to arrive equipped with OSTR and IBC technologies, Overair’s Butterfly flight testing has some hype surrounding it. That process will begin in early 2024 with a vehicle-level testing phase at its Santa Ana headquarters, followed by more expansive flight testing at a facility in Victorville, California.

Looking ahead beyond flight testing, Overair says it already has its eyes on certified eVTOL operations and has garnered interest from both commercial and military customers. We will keep an eye out in 2024 and can hopefully share footage of the Butterly prototype taking its maiden flight.

Dealers are slashing prices on 2025 Kia Niro EV, nearly 25% off!

Dealers are slashing prices on 2025 Kia Niro EV, nearly 25% off!

Just like it says on the tin – retailers are advertising killer deals on the fun-to-drive Kia Niro EV, with one midwest auto dealer reporting more than $10,000 off the sticker price of the Niro EV Wind. That’s nearly 25% off the top line price!

SKIP THE STORYget straight to the deals.

The Kia Niro EV gets overshadowed by its objectively excellent EV6 and EV9 stablemates – both of which are currently available with substantial lease cash and 0% APR financing, in fact – but that doesn’t mean it’s not an excellent little electric runabout in its own right.

The last time I had a Niro EV tester, my kids loved it, I liked that it was quicker and more tossable than I expected it to be, and my wife liked the fact that “it doesn’t look electric. It looks normal.” And, with well over 200 miles of real world range (EPA-rated range is 253 miles), it was more than up to the task of commuting around Chicago and making the trip up to the Great Wolf Lodge in Gurnee and back without even needing to look for a charger.

It’s not the primary family hauler I’d choose – but as a second car? As a primary car for a slightly smaller family (1-2 kids, instead of 3-4)? The Kia Niro EV Wind, with a $42,470 MSRP, seems like a solid, “can’t go wrong” sort of choice. You know?

You won’t even have to pay that much, though. Raymond Kia in Antioch, Illinois is advertising a $42,470 Niro EV for $32,431 (that’s $10,039, or about 24% off the MSRP), and several others are advertising prices in the $33,000 range.

And, while we’re at it:

Lion Electric leaves US school districts stuck with unsafe, broken buses

Lion Electric leaves US school districts stuck with unsafe, broken buses

Many school districts who used EPA funding to help purchase Lion Electric school buses are now stuck with broken down or unsafe vehicles – but Lion’s new Canadian investors seemingly have no plans to make things right.

“All four Lion buses that we own are currently parked and not being used,” Coleen Souza, interim transportation director of Winthrop Public Schools, told Jay Traugott over at Clean Trucking. “Two of them are in need of repairs which would cost us money which we are not willing to invest in because the buses do not run for more than a month before needing more repairs.”

The story is much the same at other US school districts who deployed Lion Electric buses over the last few years – and the trouble they describe isn’t isolated to a single component or system. One district we spoke to had onboard chargers that failed almost immediately after being plugged into a L2 AC charger. Another that spoke to Traugott reported emergency door gaps, power steering failure, loss of power, and braking issues.

As bad as the revelations of safety and drivability issues and $250 million in unresolved debt have been, it’s the objectively stupid design choices that have been the most shocking.

“Lion built an auxiliary diesel heater to heat the bus, essentially writing the manual as they went,” explained a school superintendent in the midwest, who asked not to be named. “It was fascinating to watch but there were design flaws with the heater. For example, the intakes pointed downward and we’re driving across rural roads and the intake sucks in that dirt.”

“Using a diesel-powered heater to warm an electric bus also somewhat defeats the purpose of going 100% zero-emissions,” added Traugott.

Despite a new electric school bus rebate and a fresh cash injection from Vincent Chiara, president of Quebec real estate powerhouse Groupe MACH, and Lion director Pierre Wilkie, however, it seems like no help is coming.

It just gets worse and worse

Despite early speculation – some of it my own, in fact – that the new investors would take the Canadian government up on its offer to help subsidize more electric school bus production and honor the company’s outstanding warranty claims, it appears the only vehicle line the new investors are interested in reviving are the the Class 8 electric semi manufacturing operations in Saint-Jérôme, Quebec.

The US school districts who spent tens of millions of taxpayer dollars in the hopes that Lion buses would help decarbonize their fleets and reduce students’ exposure to harmful diesel emissions? Many of them are back to using diesel, while others are trying to get their deposits back so they can buy something else.

Here’s hoping any school districts on the fence for electrification recognize that their are very real, very well-engineered, and very financially sound electric school bus manufacturers out there who can deliver on their promises.

Mitsubishi debuts EV battery swap network for cars AND trucks in Tokyo

Mitsubishi debuts EV battery swap network for cars AND trucks in Tokyo

Mitsubishi is partnering with Ample and Yamoto Transports to deploy an innovative new battery swap network for electric cars in its Japanese home market — but it’s not just for electric cars. Mitsubishi Fuso commercial trucks are getting in on the action, too!

Despite a number of early EV adopters with an overdeveloped concept of ownership, battery swap technology has proven to be both extremely effective and extremely positive to the overall EV ownership experience. And when you see how simple it is to add hundreds of miles of driving in just 100 seconds — quicker, in many cases, than pumping a tank of liquid fuel into an ICE-powered car — you might come around, yourself.

That seems to be what Mitsubishi thinks, anyway, and they’re hoping they’ll be your go-to choice when it’s time to electrify your regional and last-mile commercial delivery fleet(s) by launching a multi-year pilot program to deploy more than 150 battery-swappable commercial electric vehicles and 14 modular battery swapping stations across Tokyo, where the company plans to showcase its “five minute charging” tech in full view of hundreds of commercial fleets and, crucially, the executives of the companies that own and manage them.

A truck like the Mitsubishi eCanter typically requires a full night of AC charging to top off its batteries, and at least an hour or two on DC charging in Japan, according to Fuso. This joint pilot by Mitsubishi, Mitsubishi Fuso Trucks, and Ample aims to circumvent this issue of forced downtime with its swappable batteries, supporting vehicle uptime by delivering a full charge within minutes. The move is meant to encourage the transport industry’s EV shift while creating a depository of stored energy that can be deployed to the grid in the event of a natural disaster — something Mitsubishi in Japan has been working on for years.

Trucks like the eCanter already serve a number of roles throughout the global truck market, including municipal waste collection, regional delivery support, and more.

The pilot is backed by Tokyo Metropolitan Government’s “Technology Development Support Project for Promoting New Energy,” with local delivery operator Yamato Transport testing swappable EVs for delivery operations on both its eCanter light-duty trucks and Mitsubishi Minicab kei-class electric vans.

Electrek’s Take

Electrifying the commercial truck fleet is a key part of decarbonizing city truck fleets – not just here in the US, but around the world. I called the eCanter, “a great product for moving stuff around densely packed city streets,” and eliminating the corporate fear of EV charging in the wild just makes it an even better product for that purpose.

Here’s hoping we see more “right size” electric solutions like this one (and more battery swapping tech) in small towns and tight urban environments stateside somewhat sooner than later.
