Rolls-Royce unveiled a new convertible Tuesday that the luxury automaker is calling its "sexiest" yet. The model is called the Dawn, and it is definitely not your usual Rolls. Its contours are much more fluid, with the sides flaring out around the rear wheel wells. The front end is more rounded. It is powered by a 563 horsepower V12 engine. The car shares much of its engineering with the Rolls-Royce Wraith, a two-door hardtop, but the body is almost entirely different. Prices are expected to start around $400,000. The Dawn was unveiled at the Frankfurt Motor Show, and Rolls-Royce designers chose an exterior paint color, Midnight Sapphire, that mimicked the color of a nighttime sky. Inside, the leather seats were dyed in vibrant orange so that, as the top is lowered, the bright interior is revealed. The Dawn's name harkens back the the Rolls-Royce Silver Dawn, introduced in in the early 1950s as Great Britain was recovering from the destruction of World War II. Only 28 convertible Silver Dawns were built between 1950 and 1954. http://money.cnn.com/2015/09/08/autos/rolls-royce-dawn-conve...
