ATR and Pratt & Whitney Canada, a business unit of RTX, have announced their intent to collaborate on the development of advanced technologies for regional turboprop engines. This partnership aims to enhance the performance of current ATR aircraft and lay the groundwork for the future “EVO” model, a concept designed to redefine operational and environmental efficiency in this segment.
Technology with Purpose: Lower Emissions, Higher Performance
The focus of this collaboration is the evolution of the PW127XT engine, already in service and renowned for its efficiency. Both companies will work on innovative solutions to:
- Improve thermal efficiency, enabling further reductions in fuel consumption.
- Incorporate advanced materials to enhance engine durability and reliability, lowering maintenance costs.
- Optimize the integration of the engine, nacelle, and aircraft to refine aerodynamics and overall performance.

Progress Toward Hybrid-Electric Propulsion
One of the most groundbreaking aspects of the agreement is the exploration of the disruptive potential of hybrid-electric propulsion. This technology will be considered as part of the feasibility study for the future ATR ‘EVO,’ with the goal of combining the technical expertise of both companies to elevate regional aircraft efficiency through electrified systems.
Proven Results: PW127XT-M by the Numbers
Currently, over 1,300 ATR aircraft in service are powered by Pratt & Whitney Canada engines, including more than 60 equipped with the PW127XT-M model. Since its entry into service in 2022, this engine has demonstrated tangible results:
- Over 300,000 cumulative flight hours.
- 40% improvement in time on wing, extending the engine’s lifespan between maintenance intervals.
- 20% reduction in maintenance costs.
- At least 3% improvement in fuel efficiency compared to previous models.
Nathalie Tarnaud Laude, CEO of ATR, emphasized: “Since our pioneering collaboration with the PW120 in the 1980s, ATR and Pratt & Whitney Canada have consistently raised the bar for regional aviation. Now, with our sights set on the next generation of engines, we are driving fuel efficiency, reducing carbon emissions, and enhancing operational performance.”
Maria Della Posta, President of Pratt & Whitney Canada, added: “As we celebrate Pratt & Whitney’s centennial, this strong collaboration with ATR reaffirms our commitment to the regional turboprop segment. With over 30 derivatives specifically designed for this application, we continue to improve aircraft performance thanks to the advantages of the exceptional PW127XT engine.”
This initiative reinforces the joint leadership of ATR and Pratt & Whitney Canada in a sector that demands constant innovation, operational efficiency, and environmental responsibility. The evolution of the PW127XT engine and the exploration of hybrid technologies position the ‘EVO’ concept as a concrete step toward the future of sustainable regional aviation.
