The Maserati Boomerang is a 1972 concept car designed by Giorgetto Giugiaro and produced by Italdesign. It debuted at the 1971 Turin Motor Show as a non-functional Epowood model, then reappeared at the 1972 Geneva Auto Show on a Maserati Bora chassis. It uses a 4.7L V8 engine producing 310 hp and 460 N⋅m, driving the rear wheels through a 5-speed manual. Its interior features a rotating steering wheel around stationary gauges. Though registered as a road car, it was intended solely as a one-off show car.
The Peugeot Onyx is a 2012 concept car designed by Gilles Vidal. It uses a 3.7 L V8 diesel hybrid powertrain. Its body combines hand-beaten untreated copper and carbon fiber.

It features a double bubble roof, three-claw taillights, Cd 0.30, recycled interior materials—including felt, compressed newspaper-resin 'wood', blown crystal, and aluminum controls—and a 100 kg carbon fiber chassis in 12 parts.
