Concept Car of the Week: BMW Turbo (1972)

Built by Michelotti in Turin and unveiled at the 1972 Paris motor show, the BMW Turbo was built both as a symbol of the carmaker's strength after its troubles in the ‘60s and as a celebration of that summer's Olympic Games in Munich. This two-door coupe, based on a modified 2002 chassis with a mid-mounted engine, was born when BMW's design director Paul Bracq convinced the board to let him design a concept that would be part design exercise, part technology testbed. Safety had become an increasingly important consideration following a number of design summits in the early ‘70s, and Bracq used the Turbo to test out a number of safety solutions.

Audi hardwood bicycle

Following on from its collaboration with Head for carbon fiber skis, Audi has teamed up with Renovo Hardwood Bicycles to create yet another performance-oriented product. Audi is launching the Duo range of cycles as ‘an embodiment of its core principles of progressive innovation' that aim to blend craftsmanship and styling with performance and technology. As a result, each Duo is built around a monocoque frame that is made from hardwood, which not only increases ride comfort – thanks to the material's ability to absorb shock and vibration – but also serves to reduce weight.
