The casualties and sideshows of motoring history from around the world finally get the recognition they deserve. Revisit a motoring decade when fuel economy was top priority, the rotary engine rose and fell, and car-buyers wanted a hatchback and the latest styling and safety features. Those that made the grade found global popularity - now meet the cars left behind.

Italy's clever plan to update the Mini; the French GT coupé with an extra seat; America's electric runabout that paved the way for Tesla; Britain's stylish, homespun sports cars; the Japanese limo meant to do 25mph; the 'safety car' turned into a Polish workhorse... each one enjoys a detailed review giving the context and thinking around them.

The terrific archive images also highlight thirty 1970s design specials and one-offs - even more amazing cars pointing to a future that never quite came true.
