A team, led by endurance racer Romain Dumas, set out to explore the limits of the 911. It built a pair of experimental cars designed to tackle one of the world’s most hostile environments: the slopes of Ojos del Salado, Chile, the highest volcano in the world. Note: these cars aren’t related to the new 911 Dakar. Under the skin sits a 992 Carrera 4S, equipped with a factory standard turbocharged flat six engine that’s mated to an original seven-speed manual transmission.
