Rolls-Royce Holdings plc is set to kick off field tests on a hybrid drive setup for mining haul trucks starting autumn 2026, a move that edges its Power Systems division further into industrial power with lower emissions. Investors have been tracking whether growth away from civil aerospace can keep up the stock’s strong stretch in recent years. The system, which integrates mtu Series 4000 engines and an electric drivetrain, has the potential to trim both fuel consumption and carbon dioxide emissions by up to 30%, though actual performance will depend on how mines are laid out and run, according to the company.
The timing’s key here. Rolls-Royce wants to prove its turnaround isn’t limited to the widebody aircraft engine business—where revenue depends on engine flying hours, or EFH, logged by engines in operation. In its most recent trading update, the company said Power Systems order intake across both gas and diesel engines jumped roughly 50% year-on-year in the first quarter, driven by stronger demand from data centres and government clients. As of March’s end, the unit’s order backlog stood at £7.3 billion.
The mining project comes on the heels of Rolls-Royce’s recent move in Friedrichshafen, Germany, where the company finished building three new single-cylinder test benches. The upgrade—costing “tens of millions of euros”—is designed to accelerate progress on both diesel and alternative-fuel engines. “The groundwork for the reliable development” of next-generation propulsion tech is now in place, said Martin Urban, executive vice president engineering at Rolls-Royce Power Systems.

“Miners want to run operations ‘more efficiently and sustainably,’” said Cobus van Schalkwyk, vice president global mining at Rolls-Royce Power Systems. Rolls-Royce’s hybrid setup grabs braking energy as trucks head downhill, stores it in batteries, and then feeds it back to wheel motors for the uphill slog—relieving pressure on the diesel engine, the company said. mtu Solutions
Rolls-Royce shares last traded at 1,218.26 pence on Friday, off 3.24% for the day after a bumpy week that saw a 6.42% jump Wednesday followed by a 1.58% dip Thursday, according to market data. The stock remains comfortably above its level before the AGM, though it sits below the May 6 high of 1,329.40p.
Rolls-Royce left its 2026 outlook steady, sticking to a target of £4.0 billion to £4.2 billion in underlying operating profit and £3.6 billion to £3.8 billion in free cash flow. The group said it still expects to offset the financial hit from Middle East-related disruption. “Strong start to the year” is how Chief Executive Tufan Erginbilgic described performance across all three divisions in the latest AGM update.

Last week, Reuters noted that Rolls-Royce engines are behind the power on Airbus A350s and Boeing 787s. Airlines operating those widebody jets ran into trouble after the Iran war flared up in late February. For investors, Rolls-Royce pointed to a 5% jump in large engine flying hours during the first quarter, reaching 115% of 2019 figures—a crucial point, since so many of the company’s service contracts are pegged to engine run time.
Competition is getting sharper. Caterpillar touts its electric-drive mining trucks for cost savings and better productivity; Komatsu highlights advances in electric drive and autonomous features on its mining trucks; Cummins pushes its engines and power systems for miners, expanding into industrial hybrids. That’s the backdrop for Rolls-Royce’s risk: field trials don’t guarantee sales, and mining companies have a range of options to reduce diesel.
Big mining names aren’t waiting around. Back in December, BHP and Rio Tinto kicked off Caterpillar electric haul truck trials at an iron ore site in Australia, hoping to see if battery-electric rigs can meaningfully reduce both diesel dependence and emissions.
Chief Financial Officer Helen McCabe, along with non-executive directors Birgit Behrendt and Wendy Mars, made small share purchases under their respective share purchase plans, according to a regulatory filing published Friday. While the transactions were minor, they landed in the middle of the company’s much larger capital return initiative. Rolls-Royce is working through a £2.5 billion buyback set to run through 2026; as of April 30, more than £750 million of that tranche was already done.
Rolls-Royce’s own analyst consensus, gathered from 12 inputs in April, sees underlying EBIT at £4.13 billion and free cash flow at £3.73 billion for FY 2026—numbers that land squarely inside management’s guidance. While aerospace remains dominant, the mining hybrid push and German test-bench spend—both still on the small side—put the spotlight on a bigger issue for investors: just how much growth can power systems, defence, and newer ventures deliver beyond simply logging more flying hours?
