T he new model, t o be made at the luxury car company's headquarters at Goodwood in West Sussex, is described as delivering "effortless, open-top touring".
Rolls said the new car will build on the su ccess of the company's Phantom, Ghost and Wraith models.
Rolls-Royce Motor Cars chief executive Torsten Muller-Otvos said the announcement of the new car opened "an exciting new chapter" in the company's history.
