Built by McLaren Special Operations (MSO) and debuting at the Goodwood Festival of Speed this weekend, the 788HS is the most extreme version of the brand's second-generation supercar, sitting at the top of the heap currently made up of the 720S, 750S, and 765LT. With more power, downforce, and handling prowess than any of its kin, the 788HS promises to be one hell of a final chapter.
