Evolito to Develop Electric Wheel Taxi System with Airbus and UK Government Support

Why It Matters

Engine‑off taxi directly reduces fuel burn and carbon output, accelerating aviation’s net‑zero roadmap while showcasing UK leadership in electric propulsion.

Key Takeaways

• Evolito to build 350 kW axial‑flux taxi motor.
• Motor delivers ~56 Nm/kg torque density.
• Engine‑off taxi could cut ground emissions 47 %.
• Project SONATA unites Airbus, ATI, Innovate UK, universities.
• Supports UK Jet Zero strategy and high‑skill aerospace jobs.

Pulse Analysis

Ground operations account for a sizable share of an aircraft’s total fuel consumption, yet they remain one of the least electrified segments of aviation. Recent advances in axial‑flux motor design—offering superior power‑to‑weight ratios—have opened the door to viable engine‑off taxi solutions. By replacing thrust‑reverser‑type propulsion with dedicated wheel‑drive units, airlines can achieve immediate fuel savings and noise reductions without compromising turnaround times, a compelling proposition as regulators tighten emissions standards worldwide.

Project SONATA brings together a cross‑industry consortium to fast‑track this technology. Evolito’s D1700 motor, slated to produce roughly 350 kW at a torque density of 56 Nm per kilogram, will be packaged within the aircraft’s landing‑gear assembly, allowing direct drive of the wheels. The collaboration with Airbus, the Aerospace Technology Institute, Innovate UK and leading universities ensures that the system meets rigorous certification and integration requirements while leveraging existing supply chains. Early simulations suggest that commercial narrow‑body jets could see up to a 47 % reduction in taxi‑related emissions, translating into measurable cost savings for carriers operating high‑frequency short‑haul routes.

Beyond the immediate operational benefits, the project signals a strategic shift for the UK aerospace sector. By investing in home‑grown electric propulsion, the government aims to preserve high‑skill jobs and position Britain as a hub for next‑generation aircraft technologies. Successful deployment could spur a new market for retrofittable electric taxi kits, encouraging airlines worldwide to adopt similar solutions. However, challenges remain, including battery weight management, certification timelines, and integration with existing ground‑handling procedures. Overcoming these hurdles will be critical to scaling the technology and delivering on the broader Jet Zero ambition.
