The custom-built Rolls-Royce associated with an approximately $28 million price is the Boat Tail.
Rolls-Royce created the Boat Tail through its specialised coachbuild division, producing a trio of highly individual cars commissioned by separate clients. The model was presented in 2021 and draws its name and visual inspiration from classic boat-tailed Rolls-Royces and the sleek yachts of the 1920s and 1930s. Its rear deck opens to reveal a hosting arrangement with cocktail tables, stools, refrigeration and bespoke Christofle tableware.
Although the Boat Tail is often described as a $28 million car, that amount is a widely reported estimate rather than a publicly confirmed sale price. Rolls-Royce has not generally disclosed the private financial terms of such commissions. That makes it different from the Sweptail, another one-off Rolls-Royce frequently mentioned in discussions of ultra-expensive bespoke cars.
The Boat Tail shares its chassis and 6.75-liter twin-turbocharged V12 with the Phantom, but its bodywork and equipment include thousands of bespoke details. Only three examples were planned, reinforcing its status as a coachbuilt commission rather than a regular production model.
