ATR and Pratt & Whitney Canada Advance Sustainable Turboprop Technology
New PW127XT-M engine and hybrid EVO concept deliver fuel savings, lower emissions, and SAF compatibility for regional aviation decarbonization.

Revolutionizing Regional Aviation: ATR and Pratt & Whitney Canada’s Strategic Collaboration
In June 2025, ATR and Pratt & Whitney Canada (P&WC) announced a reinforced partnership aimed at redefining propulsion systems for regional aviation. This collaboration signals a significant leap forward in the development of more efficient, sustainable, and cost-effective turboprop engines. With a shared history spanning over four decades, ATR and P&WC are leveraging their combined expertise to push the boundaries of innovation, particularly through enhancements to the PW127XT-M engine and the development of the hybrid-electric EVO concept.
As the aviation industry faces increasing pressure to decarbonize, regional aircraft are emerging as key players in achieving net-zero emissions targets. Turboprops, due to their superior fuel efficiency on short-haul routes, already offer a greener alternative to regional jets. The ATR-P&WC partnership takes this a step further, integrating cutting-edge technology to reduce emissions, maintenance costs, and fuel consumption, all while preparing for the future of hybrid-electric propulsion.
PW127XT-M Engine: Efficiency and Sustainability in Focus
Technical Enhancements and Operational Benefits
The PW127XT-M engine represents a significant evolution in turboprop technology. Generating between 2,300 and 2,750 shaft horsepower, it features an improved overall pressure ratio of 17.97:1. This configuration enables a 3% block fuel efficiency improvement over its predecessor, the PW127M. The redesigned compressors and simplified turbine stages reduce mechanical complexity, enhancing reliability and performance.
One of the most notable advancements is the engine’s durability. Time-on-wing has increased by 40%, now reaching 12,000 flight hours before requiring an overhaul. This translates to longer intervals between maintenance, reducing aircraft downtime and improving fleet availability. For airlines like Braathens Regional, which operates 25 ATR 72-600s, this means extending maintenance cycles from 18 to 24 months.
Direct maintenance costs (DMC) have also been slashed by 20%, equating to approximately $150,000 in annual savings per aircraft. These cost efficiencies are critical for regional operators operating on thin margins, offering them a competitive edge in a challenging market.
“The PW127XT-M delivers tangible benefits, lower fuel burn, longer intervals between maintenance, and reduced lifecycle costs. It’s a game-changer for regional aviation.” , Pratt & Whitney Canada spokesperson
Advancing Sustainable Aviation Fuel (SAF) Adoption
Beyond efficiency, the PW127XT-M is at the forefront of sustainable aviation. In 2022, P&WC successfully demonstrated 100% SAF compatibility using Neste MY SAF on a Braathens ATR 72-600. This test flight showcased the potential for up to 80% lifecycle CO₂ emission reductions compared to traditional jet fuel.
Currently, the engine supports 50% SAF blends, with full 100% certification targeted by 2025, contingent on ASTM approval. This aligns with the International Civil Aviation Organization’s (ICAO) net-zero emissions roadmap, which emphasizes SAF as a cornerstone of aviation decarbonization.
However, SAF scalability remains a challenge. Global production stood at 1 billion gallons in 2025, just 2% of global aviation fuel demand. ATR and P&WC are addressing this by ensuring engine compatibility with a wide range of SAF feedstocks, including HEFA and SPK, to future-proof their propulsion systems against supply constraints.
ATR EVO Concept: Hybrid-Electric Propulsion for the Future
Design Innovation and Performance Goals
The ATR EVO concept, slated for mid-2030s entry, represents a bold step toward hybrid-electric regional aviation. It combines a PW127XT-M-based thermal engine with a 1-megawatt electric motor developed by Collins Aerospace. This setup is designed to cut CO₂ emissions by 20% and improve fuel efficiency by 30% compared to current turboprop models.
Energy storage is provided by H55 S.A.’s 200 kWh lithium-ion batteries, which recharge in-flight using regenerative turbine technology. This allows for electric-assisted takeoff and landing, significantly reducing fossil fuel use during the most energy-intensive flight phases.
Additional aerodynamic and structural improvements include a 15% reduction in engine core size, resulting in lower drag and weight. CFD simulations indicate a 4% aerodynamic gain from nacelle redesign, while an eco-friendly cabin using flax fiber composites reduces airframe weight by 8%.
Integration with Pratt & Whitney’s Hybrid Initiatives
P&WC’s own hybrid-electric demonstrator program complements the EVO initiative. In June 2025, the company achieved full-power integration of thermal and electric systems on a De Havilland Dash 8-100 testbed. This program brings together RTX’s subsidiaries: Collins Aerospace handles power electronics, while P&WC adapts geared turbofan (GTF) technology for hybrid applications.
Early testing has shown promising results, including a 12% fuel burn reduction during climb. Flight trials aim to validate a 30% overall fuel savings, consistent with the EVO’s performance targets. These synergies highlight the benefits of cross-company collaboration within RTX’s ecosystem.
As battery energy densities improve and hybrid systems mature, the EVO could pave the way for zero-emission regional aircraft. However, current battery technologies (250 Wh/kg) still fall short of what’s needed for longer-range operations, indicating that hybridization is an interim solution on the path to full electrification or hydrogen propulsion.
Market Dynamics and Strategic Positioning
Turboprop Market Growth and Competitive Edge
The global turboprop engine market is on an upward trajectory, projected to grow from $3.35 billion in 2024 to $3.58 billion in 2025 at a CAGR of 6.9%. Regional connectivity initiatives, such as India’s UDAN scheme and Africa’s expanding aviation infrastructure, are major growth drivers.
ATR currently dominates the 50–90 seat segment with a 65% market share. Competitors like De Havilland Canada have faced production setbacks, reinforcing ATR’s position. The PW127XT-M’s 3% fuel efficiency advantage translates to $200,000 in annual savings per aircraft, making it an attractive option for operators seeking cost-effective and sustainable solutions.
Compared to regional jets like the Embraer E175-E2, which consume 45% more fuel on comparable routes, ATR turboprops offer a compelling value proposition. Their ability to operate from shorter runways also opens up underserved markets, further enhancing their appeal.
Decarbonization and Regulatory Alignment
Turboprops account for 18% of global departures but only 4% of aviation CO₂ emissions. Their lower cruising altitudes also reduce contrail formation, which has a warming impact twice that of CO₂. This makes them a strategic asset in aviation’s decarbonization roadmap.
The ATR-P&WC alliance supports major policy frameworks, including the EU’s Fit for 55 package and the U.S. SAF Grand Challenge. These initiatives aim for substantial emissions reductions and increased SAF production by 2030, aligning with the partnership’s goals.
With the European Union’s Carbon Border Adjustment Mechanism (CBAM) set to penalize high-carbon aviation from 2027, ATR’s 100% SAF roadmap and hybrid R&D position it well to meet future regulatory requirements and capture emerging market opportunities.
Conclusion and Future Outlook
The collaboration between ATR and Pratt & Whitney Canada exemplifies how long-standing partnerships can drive meaningful innovation. The PW127XT-M engine sets new benchmarks in efficiency and sustainability, while the EVO concept introduces a viable path toward hybrid-electric aviation.

Archer and Formula 1 to Explore Air Taxi Flights at Grand Prix Races
Archer and Formula 1 announced a multi-year partnership to study Midnight eVTOL transfers for VIPs and fans at select Grand Prix circuits.

Archer Aviation and Formula 1 have announced a multi-year partnership to explore flying VIPs and fans to and from Grand Prix circuits aboard Archer’s Midnight electric air taxi, including dedicated landing points at circuits and air taxi services within F1’s hospitality and ticketing offerings.
Archer announced the agreement in a press release dated November 12, 2026. The partnership covers select Grands Prix that align with what Archer calls key commercial markets in the US, the Middle East, Asia and Europe. The release gives no financial terms and no date for a first air taxi flight at a race, and it describes the work as something the partners will explore.
What the partners plan to study
According to the release, the two companies will look at dedicated air taxi drop-off and pick-up locations at circuits, and at including air taxi services in F1’s hospitality and ticketing offerings. Once Archer’s commercial electric vertical takeoff and landing (eVTOL) operations launch in F1 markets, fans could skip traffic between major airports, business hubs and other key destinations, Archer said.
Emily Prazer, Chief Commercial Officer of Formula 1, said in the release:
“Innovation is at the heart of Formula 1, and Archer shares our passion for pushing boundaries and exploring what is possible.”
Adam Goldstein, Archer’s founder and CEO, pointed to the size of the sport’s audience, saying “With 830 million fans worldwide, Formula 1 gives us a global audience of prospective passengers”. He added that motorsport and aerospace share the same engineering DNA, and that the companies hope to show how innovation on the ground and in the sky could combine for fans at the track.
Archer also drew a technical comparison. It said the power-to-weight demands of eVTOL aircraft are comparable to those of F1, and that, as in an F1 car, its electric propulsion, advanced composites and aerodynamics are engineered as one system.
Where Archer’s planned networks meet the race calendar
Archer said its planned US air taxi networks map closely to F1 race locations, including Miami and Texas, where it has unveiled planned infrastructure networks. Its Texas plan, announced on October 23, 2026, includes an Austin network connecting Austin-Bergstrom International Airport and Austin Executive Airport with the F1 Circuit Helipad at the Circuit of the Americas, which Archer said would put Formula 1 United States Grand Prix races minutes away. The same plan covers Dallas-Fort Worth and Houston, and Archer said Midnight could turn 60 to 90 minute ground trips into 10 to 20 minute flights.
In South Florida, Archer’s Miami network plan of December 2025 named Hard Rock Stadium, home of the Formula 1 Crypto.com Miami Grand Prix, among the sites whose existing helipads will be prepared for electric operations. That network would also link Miami International Airport (MIA), Fort Lauderdale-Hollywood International Airport (FLL) and Palm Beach International Airport (PBI).
The partnership already has a public side. Archer displayed Midnight at the Formula 1 United States Grand Prix in Austin, October 22 to 25, in the Fan Zone and F1 Paddock as an Official Supporter of F1, and the aircraft will be displayed again at the Las Vegas Grand Prix and the Abu Dhabi Grand Prix later in 2026, according to the release. Archer’s third-quarter results release of November 9, 2026, had already said the two companies were forming a multi-year strategic alliance.
Where Midnight stands
Midnight is a piloted electric air taxi that carries up to four passengers and has 12 total engines and propellers, according to Archer. In its third-quarter update and FAA certificate news, Archer said Midnight had received a Market Survey Special Airworthiness Certificate from the FAA, which the company expects to allow operations in Los Angeles. The company said it is preparing to carry passengers under the US Department of Transportation’s eVTOL Integration Pilot Program (eIPP) and for the LA28 Olympic Games.
The eIPP is the framework for Archer’s planned Texas and Florida operations. In March 2026, the Department of Transportation and the FAA selected Archer’s partners in Texas, Florida and New York for the program, and Archer said at the time that it planned early Midnight operations in those states as soon as the second half of 2026. Archer, BETA and Macquarie Capital also launched the ACES charging consortium, which aims to electrify up to 250 air taxi sites across America by 2030 and is working with the Texas Department of Transportation on charging to support eIPP operations in Texas.
Archer reported third-quarter 2026 revenue of $5.1 million and a net loss of $274.6 million, with total liquidity of $1.4 billion. The company said its acquisition of Boeing’s Wisk, Insitu and SkyGrid businesses is nearing close, subject to certain regulatory approvals and other closing conditions.
What the announcement leaves open
The release names no race where air taxi transfers would be offered first, and gives no pricing or start date. It ties services for fans to the launch of Archer’s commercial eVTOL operations in F1 markets.
Archer’s forward-looking statements list aircraft design and specifications, development and certification timing, air taxi network plans including the eIPP, and the expected benefits of collaborations such as the one with Formula 1 among the matters that could differ from its plans.

Eve Vector Software Handles Over 100 Helicopter Flights at Interlagos
Eve Air Mobility’s Vector software managed helicopter slots for Revo at Interlagos, peaking at more than 100 flights on November 8, 2026.

Eve Air Mobility’s Vector software managed landing and takeoff slots at the temporary helipad serving São Paulo’s Interlagos Circuit during the motorsport weekend there, with traffic peaking at more than 100 helicopter flights on Sunday, November 8, 2026. Revo, the São Paulo helicopter operator that Eve calls its first electric Vertical Takeoff and Landing (eVTOL) aircraft customer, ran the system at the event for the second year in a row.
In a press release distributed on November 13, 2026, Eve, an Embraer Group company, said Revo’s team used Vector at the helipad set up at the Ayrton Senna Kart Track, next to the circuit, for scheduling and slot management of landings and takeoffs. Eve described the event as the largest international motorsport event, and said the software had been tested at the same event in 2025.
What Vector did at Interlagos
Vector is Eve’s urban air traffic management software. According to the release, it is built on a modular architecture, with Helipad and Vertiport (Aerodrome) and Ground Operations modules that let operators manage high-volume activity across vertiports and helipads. Eve said the software is designed to provide safe and efficient low-altitude air traffic management through automation and data-driven services, and said it represents a new step toward automated, scalable traffic management for Advanced Air Mobility (AAM) in Brazil and worldwide.
Eve said its team supported Revo’s operational staff throughout the weekend so that operations ran smoothly, effectively and “100% safely” across all three days of the event. The release does not give a total number of flights for the weekend or the number of helicopters involved; the only traffic figure is the peak of more than 100 flights on the Sunday.
Johann Bordais, chief executive of Eve Air Mobility, tied the result to the weekend’s traffic:
“The efficient use of Vector over a weekend that concentrates one of the highest volumes of helicopter traffic in Brazil throughout the year demonstrates the full maturity of our solutions for the urban mobility ecosystem.”
Bordais added that Revo will be Eve’s first eVTOL customer in Brazil and globally. João Welsh, chief executive of Revo, said the partnership with Eve “represents a major step in this direction,” both for bringing eVTOLs into Revo’s operations and for developing urban air traffic management solutions.
How the 2026 deployment compares with 2025
This was not Vector’s first outing at the circuit. On November 10, 2025, Eve announced the software’s first real-world deployment, with Revo, during the 2025 São Paulo Grand Prix. Revo’s team used Vector from November 7 to 9 that year to manage helicopter operations at the Interlagos racetrack, after training by Eve’s TechCare and Vector teams. Eve said at the time that future Vector operations were planned at other sites, including residential and commercial hubs.
The product description has moved since then. In November 2025, Eve listed a Vertiport and Ground Operations Module and said a Fleet Operations Module for helicopter and eVTOL operators was planned for 2026. The November 2026 release lists separate Helipad and Vertiport (Aerodrome) and Ground Operations modules and gives 2027 for the Fleet Operations Module. The release does not explain the change in timing. Eve says the fleet module will address the needs of helicopter and eVTOL operators as Urban Air Mobility networks expand.
The Revo contract behind the partnership
Revo is part of Omni Helicopters International (OHI), which, according to the November 2026 release, manages a fleet of approximately 90 helicopters and operates over 1,500 weekly flights. In a release dated June 15, 2025, Eve announced its first binding framework agreement with Revo and OHI, covering up to 50 eVTOLs, entry-into-service support and aftermarket services, including Eve’s TechCare package. Eve’s release for that deal was headed as a $250M contract, and the earlier work between the companies had included simulations of urban air traffic management using Vector.
The June 2025 release named Revo as launch operator for Eve’s eVTOLs in São Paulo, with first delivery planned for Q4 2027, and said the city has over 400 registered helicopters and nearly 2,000 daily takeoffs and landings. The November 2026 release says Revo is positioned to operate the technology in Brazil starting in 2028.
Where Eve’s eVTOL program stands
Eve reports a backlog of over 2,700 aircraft, including firm orders and letters of intent, across 28 customers in 10 countries. It has completed more than 73 flights since its flight test campaign began in 2025, after more than 10,000 hours of integrated ground testing. On August 3, 2026, Eve announced its first partial transition flight, in which the prototype’s rear pusher propeller was activated in the air for the first time and the aircraft reached a stabilized speed of 27 knots.
Eve plans to build six certification prototypes for a certification campaign starting in 2027, working with Brazil’s National Civil Aviation Agency (ANAC) and the FAA. Once the aircraft is certified, and through the end of 2028, it will be built at a facility under development in Taubaté, São Paulo, with initial capacity of up to 120 aircraft per year and room to expand to up to 480 aircraft annually.

SkyDrive Adds Tobu as Fifth Railway Partner for Kanto eVTOL Services
Tobu Railway and Tobu Top Tours have invested in SkyDrive to develop vertiports, biometric boarding and tours for eVTOL services in Kanto.

SkyDrive has taken new investment from Tobu Railway Co. Ltd. and Tobu Top Tours Co. Ltd., making the Tobu Group its fifth Japanese railway partner and giving the electric vertical takeoff and landing (eVTOL) developer a base for vertiports, ticketing and tour packages in the Kanto region around Tokyo ahead of the commercial services it plans for 2028.
SkyDrive announced the funding, made through a third-party share allotment, in a press release dated November 12, 2026, from Toyota City, Japan. The company did not disclose the amount. The partners say they aim to speed up commercial eVTOL deployment in Kanto by combining Tobu Group’s transportation and tourism assets with SkyDrive’s aircraft development and operational expertise.
What each Tobu company brings
The release sets out three areas of work. Tobu Railway will use its rail network, regional presence and tourism assets, especially in the Nikko area, to establish and promote vertiports. The partners will also use Tobu Railway’s “SAKULaLa” common biometric authentication platform, which Tobu Railway developed jointly with Hitachi, Ltd., for identity verification and boarding pass clearance.
Tobu Top Tours will act as an operational connector, using its destination management expertise and municipal networks to design new business models and to package secondary transport. The partnership covers business development and ground infrastructure planning across Kanto.
Tomohiro Fukuzawa, founder and CEO of SkyDrive, said the company is “thrilled and deeply encouraged that Tobu Railway and Tobu Top Tours share our vision for the future.” He said eVTOLs need more than aircraft, namely connections to transit networks, vertiports and regional travel experiences, and that SkyDrive and the Tobu Group “will work toward launching commercial services in 2028 to make air mobility a daily choice.”
A rail-first network strategy
SkyDrive has built its domestic plans around railway operators, working with major Japanese railway companies on urban networks that combine train travel with eVTOL flights. Before Tobu, SkyDrive had partnership agreements with four railway companies, each tied to specific routes: Kintetsu Group Holdings in the Ise-Shima area; Osaka Metro, with its “Osaka Diamond Route” linking four key locations in Osaka; East Japan Railway Company (JR East), for routes between Morioka and AZUMA FARM KOIWAI; and Kyushu Railway Company (JR Kyushu), in Oita Prefecture, including the Beppu and Yufuin hot spring areas. SkyDrive says it has worked with these operators on feasibility studies and flight demonstrations.
In October 2025, ahead of the Japan Mobility Show 2025 in Tokyo, SkyDrive announced an exhibit built around a boardable mockup of its SD-05 aircraft, entered through a touch-and-go automatic ticket gate, alongside panels showing planned flight routes. The company said at the time that the aim of the railway partnerships was convenient travel combining rail and urban air mobility, along with regional development and public acceptance of the technology. The Tobu agreement brings that model to Kanto.
Where SkyDrive stands
SkyDrive, based in Toyota, Aichi Prefecture, began testing eVTOL prototypes in 2014 and was incorporated in 2018. In 2019, it says, it became the first company in Japan to fly a crewed eVTOL. It flew uncrewed demonstration flights at Expo 2025 Osaka, Kansai, Japan, and says it is now working through certification steps toward type certification. It is commercializing with local partners and municipalities in 10 countries.
Manufacturing rests on an automotive partnership. SkyDrive and Suzuki Motor Company signed a commercial and technology partnership in March 2022, SkyDrive set up the manufacturing subsidiary SkyWorks in September 2023, and production began in March 2024 at a Suzuki Group plant in Iwata City, Shizuoka Prefecture. Suzuki has also invested in SkyDrive and supports its business development in India, and Naoki Ishii, Representative Director and Executive Vice President of Suzuki, was appointed an independent SkyDrive director.
The Tobu funding is one of several announcements SkyDrive has made since late October 2026. Its news page lists a memorandum of understanding (MOU) with six Singapore technology companies on advanced air mobility research and development on October 29, 2026, and an MOU with Goyang Special City and Verty on commercial eVTOL deployment in South Korea on November 4, 2026. In Kanto, the Tobu partnership is meant to support SkyDrive’s 2028 service plans for the SD-05.
