Ford La Galaxie, 1958. Designed by Elwood Engel using jet plane styling and futuristic detailing, the La Galaxie was the centrepiece of Ford's stand at the Chicago Auto Show. The reverse-angle rear window featured on Lincolns and Mercurys in the lat 50s and early 60s. Engle moved to Chrysler where he recycled some of the La Galaxie's styling for the 1963 Chrysler Turbine car. Like many "dream cars"of the 50s and 60s the La Galaxie was destroyed after its brief show career
Ford Seattle-ite XXI (incl brochure), 1962. Presented at the Century 21 Exposition which formed part of the Seattle World’s Fair (hence the name) a scale model theoretically powered by nuclear fusion. Designed by Alex Tremulis who proposed interchangeable power units so the entire front of the car could be removed. The "compact nuclear propulsion devices" would come in economy form offering perhaps 60hp, up to a high-speed transcontinental unit with in excess of 400hp. It also proposed features that did make it into real cars like computerised navigation and fingertip controls
Lamborghini Countach from the Chattanooga Motorcar Festival—owned by the Cathy Truett car collection (owner of CFA). My understanding is only eight of them were painted in this color and less than 2000 were made altogether.
