The Sweptail is the firm’s first coachbuilt car of the modern era and is the result of a four-year project with one of its “most valued customers”.
Described as the “automotive equivalent of Haute Couture”, the Sweptail has the largest grille of any modern Rolls.
It has an uninterrupted glass roof which is believed to be one of the largest, and most complex, ever seen on any car.
The unique Roller is understood to have cost around £10 million, which makes it the most expensive new road car ever built.
It has been built for an unnamed gentleman who is understood to be a connoisseur and collector of distinctive, one-off items including super-yachts and private aircraft.
Torsten Muller-Otvos, chief executive officer at Rolls-Royce Motor Cars said: “Sweptail is a truly magnificent car.
“It exudes the romance of travel for its own sake, and immediately places ‘Sweptail’ in the pantheon of the world’s great intercontinental tourers.
“Rolls-Royce’s history as the world’s leading coachbuilder is at the very core of its identity as the world’s leading luxury brand.
“Sweptail is proof, today, that Rolls-Royce is at the pinnacle of coachbuilding.
“We are listening carefully to our most special customers and assessing their interest in investing in similar, completely exclusive coachbuilt masterpieces.
“At the same time we are looking into the resources which will allow us to offer this unique service to these discerning patrons of luxury.”
That is about 4.95 billion naira on wheels.
