Rolls-Royce is celebrating a major milestone for its Trent XWB-84 Enhanced Performance (EP) engine, which has delivered almost double the baseline of anticipated fuel savings during its first year in service.
Enabled by the ongoing transformation of Rolls-Royce, the first Trent XWB-84 EP entered service in May 2025 as part of a £1 billion investment in its modern Trent fleet. Certified with a two-decibel noise reduction and an initial one percent fuel burn saving compared to the standard Trent XWB-84, data from the first 34 engines in service across three major operators shows the engine is delivering a 1.8% reduction in fuel consumption.
This improvement translates to around $450,000 in annual fuel savings per aircraft, or around $9 million per year for a typical fleet of 20 Airbus A350-900s. The Trent XWB-84 EP is on track to reach 100,000 flying hours in its first year, demonstrating its reliability and positive impact on customers’ operational efficiency and sustainability.
Adam Davies, Director Commercial Aviation, Trent XWB for Rolls-Royce, said: “This milestone is proof that the investments we have made in our Trent family are delivering real-world results, supporting our customers’ operational efficiency and sustainability goals. We are delighted our target of at least one percent improvement in fuel burn has been comfortably surpassed. I would like to thank our customers, for their ongoing trust in the Trent XWB family.”
Rolls-Royce continues to produce both the standard and EP variants of the Trent XWB-84 to meet diverse customer needs, with the EP engine now setting a new benchmark for fuel efficiency in the industry.
