Nico Rosberg explains his 2011 steering wheel with KERS [video]

In a promotional video for the Mercedes GP Formula One team, Nico Rosberg shows how an F1 steering wheel works, including the extra switches for KERS (Kinetic Energy Recovery System) and the DRS (Drag Reduction System) device.

Rosberg explains how the KERS is deployed and how its harvesting can be adjusted.

“It shows how much harvesting is happening, so you can reduce or increase with this rotary here,” he says at some point, referring to the rotary switch for the KERS deployment.
