Rolls-Royce unveils Sweptail one-off built for wealthy client

It is reportedly the most expensive new car ever sold.

A new bespoke Rolls-Royce seeks to take the crown for the most expensive new car ever sold.

The Rolls-Royce and is a one-off two-seater custom-built by the company's coachworks that the Telegraph says is worth £10 million (more than $12.8 million dollars American). The project began in 2013 when a customer approached the company seeking a request for a tourer recalling the boat-tail style speedsters of the early 20th century.

Rolls-Royce did not reveal the buyer's identity, only stating that he was "A connoisseur and collector of distinctive, one-off items including super-yachts and private aircraft." The project began when the mystery one-percenter approached the company in 2013. Inspiration for the car reportedly came from classic Rollers of the 1920s and 1930s as well as yachts the owner is apparently fond of.

The front takes the corporate face and adds what the company says is the largest grille of any modern Rolls-Royce, milled from a single block of aluminum and hand-polished. The car's most distinguished feature is the sloping roofline that tapers from inward from the C-pillars to a point at the tail. Both front and rear fascias are outlined, the front in a large, radiused square jawline and the rear in a "raked stern" emphasizing the connection with luxury yachts. The roof is highlighted by a sweeping panoramic glass roof.

The Sweptail was unveiled at the Concorso d'Eleganza at Villa d'Este in Italy, as a demonstration of what Rolls-Royce's coachbuilding division is capable of.
