Facts and figures about the Tianmen record drive

Drive e-mobility to the top – that was the remit assigned to Romain Dumas and the Volkswagen ID.R for its record-breaking run on Tianmen Mountain in China. A glance at the data analysis shows just how successful the plan on 02 September 2019 was and why the electric sports car from Wolfsburg is rightfully seen as the racing forerunner to the Volkswagen ID. family. The “first motorsport ascent” of Tianmen Mountain, with its 99 hairpins spread over 10.906 kilometres, was a holistic and impressive team performance, in which the engineers, mechanics, driver and logistics experts were all on top form.

"Some figures are as exciting as a thriller.”
