VONNEN, a California-based company under the same ownership as Elephant Racing (the suspension supplier for my Keen Project Safari 911), has a new kind of performance part: an aftermarket hybrid system, designed for cars that were never supposed to be hybrid.

In this video, CEO Chuck Moreland takes us through how the system works and is installed in their demo car, a 2013 Porsche 911 Carrera with PDK.
