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.
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.
