The Rolls-Royce Phantom Tranquility happens to be one of the most exclusive cars in the world. In addition to a luxurious interior that boats highly reflective stainless steel, 24-karat gold plating and space grade aluminum, other features include a monstrous 6.75-liter, twin-turbocharged, N74B68 V-12 engine built by BMW. In a statement released by Rolls-Royce, the Phantom Tranquility was “created for those who conceive and achieve the impossible, Tranquillity is an expression of Phantom’s standing as the rarest and most desired object in the luxury world”. Pricing has yet to be released, but production of the latest member of the Rolls-Royce family will be limited to just 25 units.
