There is an INVISIBLE FRIEND that helps power up the I.D. R on the go
The I.D. R is a helpful so-and-so. During the race, Volkswagen estimates it can produce up to 20 per cent of the required energy to scale Pikes Peak. The electric motors, when not offering Dumas the insane force needed to climb the mountain, turn into generators under braking.
Think about it this way. Power from Romain’s left foot (brake) flows back into the battery, which helps power Romain’s right foot (accelerator). There are brakes, of course, but as mentioned, operated via a brake-by-wire setup.
“The interplay between recovery and mechanical braking is controlled by electronic systems that the driver does not even notice,” VW’s head of electrics Marc-Christian Bertram explains.
See? INVISIBLE FRIEND.
