Paul Walker crash 'caused by speed'

CRASH INVESTIGATORS have determined that the Porsche carrying "Fast & Furious" star Paul Walker was travelling at approximately 90mph when it lost control on a California street and smashed into a light pole, killing the actor and his friend. A person who has reviewed the investigators' report said that it concluded unsafe driving, not mechanical problems, caused the crash. The report says driver Roger Rodas was going between 81mph and 94mph when his 2005 Porsche Carrera GT began to drift as it lost control after coming out of a curve.

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.
