Romania’s Transfăgărășan was blasted through the Carpathians in 1974, officially for tanks. A man whose job is to shout at cars crowned it the best road in the world in 2009. In between: hairpin bends taking you from just under 500 to over 2,000 metres in altitude, three decades of tarmac and Europe’s largest population of brown bears – some of whom have a soft spot for pizza. We’re on our way up. In the Audi e-tron GT. So, silently.
