Derby-based engine maker Rolls-Royce has completed its £2 billion acquisition of Rolls-Royce Power Systems (RRPS), the German diesel engine supplier — previously known as Tognum — that it originally acquired jointly with Daimler three years ago.

John Rishton, the CEO of Rolls-Royce, said: “We are pleased to welcome Rolls-Royce Power Systems fully into Rolls-Royce. The business adds scale and capability to our reciprocating engines portfolio. It has outstanding technology, operates in long-term growth markets and has proved a valuable addition to our Marine & Industrial Power Systems division.”

Ulrich Dohle, CEO of RRPS, said: “With our well-known high-speed engines, distributed energy systems, medium-speed engines and fuel-injection systems, we are proud that we are now a full member of the Rolls-Royce family and look forward to contributing to its success.”
