Mercedes-AMG and Cigarette Racing’s 2,250-HP Nighthawk Speed Boat Hits 90 MPH

The boat is influenced by the GT Black Series in other ways as well, mainly in its extroverted design sensibility. Slathered in Magmabeam Orange paint—a special color reserved only for this unique sports car—and tattooed in tessellated AMG logos, it features a kind of ombre fade, stern to bow, from orange to black, making it noticeable, even in the literal sea of candy-colored superboats that occupy the myriad waterways around Miami, where we enjoyed an afternoon of test rides.
