Vintage photos show Ford Mustang I and the elusive XD Cobra

It's hardly surprising that our readers want to share their memories of the Ford Mustang -- 50 years is a long time for an automotive nameplate to endure, and the model's upcoming 50th anniversary is as good excuse as any to look back on the experiences that have made the car an enthusiast hit. Take William Drew, who had a close encounter with pony car history when he saw the Mustang I concept, plus a rare Ghia-bodied Shelby Cobra concept, at an auto dealer in Dallas in 1970. His slides (taken with a Yashica camera, he notes) show the unusual cars in the nice, bright colors of Kodachrome.

Hackmobile Transit Connect wins Ford and MAKE magazine grand prize

The Hackmobile was designed by Jon Atkinson, Becca Steffen, Riley Harrison and Michael Freiert, members of Twin Cities Maker.

RCA Citroen/Exa Double Challenge project

Second year students at the Royal College of Art in London revealed a series of projects at their interim degree show last week. Developed in collaboration with French automaker Citroen and the Exa Corporation, a leading supplier of aerodynamic software, the Double Challenge project asked students to design an ultra-compact model that could establish a unique Citroën e-vehicle aesthetic for the future, all while adhering to certain aerodynamic criteria that would not only reduce energy consumption and ensure stability at speed, but also visually communicate efficiency through its design. The project, which kicked off in October last year, was closely followed by representatives from Citroen and Exa, who examined each of the projects and chose a winner, Heikki Juvonen, at the event last week.
