The sales of Rolls-Royce cars will likely be flat this year but could potentially double next year as the global economy is expected to recover and as the firm introduces new models, a company official said on Friday.

It could be anything from 50 percent higher to 100 percent higher, Graeme Grieve, sales and marketing director of Rolls-Royce, a unit of German car maker BMW , told Reuters in an interview.

Grieve also said sales of Rolls-Royce in the first quarter had been stable despite the weakening global economy.
