Concept Car of the Week: AMC Amitron (1967)

While the American auto industry spent most of the late ‘60s creating huge barges powered by monstrous engines with loud decals on disco paint jobs, AMC believed in the future of compact cars, fuel economy, and go-faster stripes. Designed under Richard Teague's supervision, the quirky Amitron was unveiled in 1967 in a hotel in Detroit. Measuring less than 2,200mm long, it is 350mm shorter than a Smart Fortwo and its wide track gave room for three passengers seating abreast.

Gibbs Sports Amphibians launches the Quadski

Gibbs Sports Amphibians has unveiled the Quadski, an amphibious all-terrain vehicle that, according to company founder Alan Gibbs, obliterates the distinction between land and water transportation. The 1,300-pound, 10.5-foot-long Quadski looks a bit like a jet-powered personal watercraft sitting on top of a single-seat ATV, but it's what's underneath the vehicle's molded composite body that separates the high-speed Quadski from larger, slower amphibious predecessors. The Quadski draws power from a BMW K 1300 Motorrad motorcycle engine capable of producing 175 hp.
