Scott Janson:
Chevrolet Performance – Developing High Performance Parts

This weeks interview is with Scott Janson, high performance suspension engineer and group leader at Chevrolet Performance. Scott started his career path with the intention of being a crew chief on a Nascar team. He took many automotive repair and technical classes and planned to graduate with a Bachelors in Automotive repair. Eventually he graduated with a  degree in Mechanical Engineering instead. Word got around that he knew how to do high performance work and he gained a reputation for suspension tuning and design for race cars.

While he did not become crew chief he did work hard and obtained a job designing performance chassis and suspensions in GM high performance vehicles. Scott told me it was not easy and he applied to over 70 positions before getting accepted at General Motors. He had previously worked for a couple tier one suppliers designing suspension components such as control arms. His time at the supplier level gave him an experience in chassis engineering that was valuable in obtaining the dream job he has now.

I asked Scott about the future of autonomous vehicles and he believes that they are going to be here sooner then most people think. Even though he loves to drive performance vehicles there is a segment in America that would much rather sit back and let someone else do the driving. The safety and convenience aspects are driving the industry to make self driving cars very soon but there will always be those wanting to be in control of the vehicle.

Thanks for the interview Scott! See you at the Woodward Dream Cruise!

All this will come together is a very special one off serpentine belt drive system in the Chevy. Update: News blast regarding the website, there will soon be a  completely new format.
