Rolls-Royce has introduced the Trent XWB-84 Enhanced Performance (EP), ushering in a new era of efficiency, sustainability, and profitability for airline operators worldwide.
As the world’s most efficient large aero engine, the Trent XWB-84 was designed exclusively for the Airbus A350, setting the industry standard with exceptional fuel efficiency, reliability, durability, and versatility. The engine currently delivers a 25% reduction in fuel burn and CO₂ emissions, powering some of the longest commercial flights with unprecedented economy.
Building on this legacy, Rolls-Royce’s latest suite of advanced enhancements further elevates the Trent XWB’s performance. The Trent XWB-84 EP achieves an additional minimum 1% reduction in fuel consumption, translating into average annual fleet fuel savings of approximately $5 million. This improvement also reduces carbon emissions and operating costs while delivering quieter operation—cutting noise by up to two decibels—without sacrificing the engine’s renowned durability.
Designed with future sustainability in mind, the Trent XWB-84 EP is certified to run on Sustainable Aviation Fuel (SAF) blends of up to 50%, with the capability to operate on 100% SAF anticipated in the near future.
Ensuring the engine maintains its world-leading durability, Rolls-Royce engineers conducted one of the company’s most rigorous development, certification, and maturity programs to date. The Trent XWB-84 EP underwent thousands of hours of exhaustive testing, both on the ground and in-flight, across eight development and three flight test engines. These engines consistently exceeded all performance and certification requirements before receiving official certification in December 2024.
With the Trent XWB-84 EP, Rolls-Royce continues to push the boundaries of aero engine technology, delivering enhanced value, sustainability, and operational excellence to its airline customers.
