S18·E8 Episode 8

Britain’s motorway network seems constantly clogged by road repairs. William Woollard asks why the surfaces need rebuilding so frequently, and looks at an alternative way of funding road repairs being tried out in Arizona. Also in America Chris Goffey reports on a glimpse into the future shape of the car, through the eyes of design students at Detroit’s Centre of Creative Studies. What was it like to race motor cars at the turn of the century? The first car to carry the British Racing Green, a Napier, has just returned to Britain, and Tiff Needell test-drives it over the tracks and lanes round its new home at Beaulieu. In the car of the decade series, it’s the 50s and a car whose shape and engineering would make it remarkable 30 years later; the Citroen DS.
