First unveiled at the 2007 Tokyo motor show and featured an incredible sweeping design which seemed to have been inspired by pictures of flying saucers.
The car, which Mazda said it wanted to put into production, would have featured a rotary engine based on that which powers the company's RX8.
The Ford Bronco concept was unveiled in 2004. It was reminiscent of the original Ford Bronco include the boxy, upright roofline, short wheelbase, round headlamps and the Bronco nameplate milled into the modern three-bar grille.
A winch and guide rollers were integrated into the lower fascia. Exterior details include exposed door hinges, cowl vents and flared wheel wells. Unique loop-shaped door handles are integrated into the door panels and open with a tug. Given the collapse in demand for SUVs in the United States, it is doubtful that this concept will ever make it into production.
