The Rocket is a hugely modified Ford Mustang, and in Speedster form it has lost its rear seats. Like the Coupé, the Speedster has all-carbon bodywork, made almost entirely by hand, with flared arches and side-skirts. At the rear there are brake scoops in front of the rear wheels, plus an integrated boot spoiler and a large aero diffuser underneath. At the front a special hexagonal grille sits above a racer-influenced front splitter, with behind it a long sculpted bonnet.
