Run by BMW since 1998, the prestigious brand whose models include the Ghost and Phantom, sold 4,107 cars across more than 50 countries in 2018, the highest annual figure in Rolls-Royce's 115-year history.
Sales jumped more than 22 percent compared with 2017, when 3,362 Rolls-Royces were bought.
The UK-made vehicles were most popular in the Americas, Rolls said in a statement, adding that its workforce surpassed 2,000 for the first time.
"2018 was a most successful, record-breaking year for Rolls-Royce," said its chief executive Torsten Muller-Otvos.
"We have seen growth in all our regions around the world (...) We set a formidable mark in 2018: I am confident it will prove the spur to even greater success in 2019."
