Engine manufacturer, Rolls-Royce has celebrated “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.”
According to Rolls-Royce, “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.”
Rolls-Royce said: “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.”
“For the last 10 years, longstanding Rolls-Royce partner, Singapore Airlines, has relied on the Trent XWB-84 to power its A350-900 medium-haul, long-haul, and ultra-long-range operations.” Rolls-Royce added.
Senior Vice President, Engineering, Singapore Airlines, Mr. Lau Hwa Peng said: “Since 2016, the Rolls-Royce Trent XWB-84 engine has played an important role in Singapore Airlines’ Airbus A350-900 operations. It has enabled us to successfully grow our network and operate on some of the most challenging routes, including the world’s longest non-stop services to the United States with our A350-900 ULR aircraft. We also appreciate the continued collaboration and support from Rolls-Royce, including ongoing improvements for the Trent XWB-84 EP, which contribute to better fuel efficiency and help strengthen network resilience.”
Director Commercial Aviation, Trent XWB for Rolls-Royce, Adam Davies 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.”
Rolls-Royce stated that it “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.”
According to Rolls-Royce, “As versatile as it is reliable, the Trent XWB-84 has shown it is equally efficient at powering short-haul or long-haul flights, which makes it the ideal solution for airlines. The 1% fuel burn efficiency improvement on the Trent XWB-84 EP can bring $5m fuel savings annually for a fleet of 20 aircraft, as well as a commensurate CO2 emissions improvement without compromising the robust durability and reliability of the engine.”
