“My first contact with OptimumG was attending one of their Applied Vehicle Dynamics Seminars. It was during this seminar I heard about and became interested in the OptimumG Internship Program and after completing my post-graduate studies I moved to Denver to work with OptimumG.

Reflecting on my time with OptimumG, one of the most important take-aways was the immense increase in my understanding of the fundamentals of vehicle dynamics and tyre behaviour. A lot of my day-to-day was spent immersed in tyre/vehicle data, kinematics and simulation work which forced my fundamentals to become strong.

I think every person that goes through an internship at OptimumG will have a unique experience depending on their interests, skills, effort and which projects are going on within the company at the time. I was fortunate to spend a lot of my time racing in both IMSA and WEC in a few different capacities. This not necessarily typical, but for me it was perfect as it’s what I’m passionate about.

Another highlight for me was the chance to live in Denver which is a fantastic area and city to live in. If you’re interested in the outdoors, hiking, running, skiing and beautiful scenery in general then you would love this too.

The experiences I had, the industry contacts I made and the friends that I still have to this day mean I look back fondly on my time with OptimumG. Without a doubt it opened many doors for me and I continue to reap the benefits of my time there every day. I would encourage anyone that is considering it to roll the dice and give it a go.”

– Tim White, Performance Engineer for Tickford Racing in V8 Supercars

“Doing the Internship was a life changing experience. It was brilliant, both from the technical and human side. It made me grow, it improved me as Race Engineer and it opened the door to an amazing Motorsport career which I could not achieved without Claude’s help. Absolutely recommended.”

– Angel Baena, Head of Simulator Program, McLaren Racing

“I first met Claude when I was studying mechanical engineering in Paris in the early 2000s. I decided to invest in his 3-days seminar on vehicle dynamics and data analysis. This was probably the best investment I have ever made as it gave me a very important and solid understanding of Motorsport Engineering principles, both theoretical and practical, that you could not acquire just by reading books. Following this seminar, I went to Denver to work with Claude for a 1-year internship working on all aspects of vehicle dynamics, Motorsport Engineering, and data analysis for a new 12-days seminar Claude was creating. This was a very valuable experience and my knowledge of Motorsport Engineering increased exponentially during this time. To this day, in my current job as a Race Engineer in F1, I am still mainly employing principles I learnt during this period. I can strongly recommend Claude’s seminar for anyone aspiring to have a career in Motorsport Engineering.”

– Julien Simon-Chautemps, Senior Race Engineer for Kimi Raikkonen, Alfa Romeo Racing – F1 Team

“I met Claude for the first time in 2000 in Paris as I attended his Vehicle Dynamics Seminar. Being still a student, I stayed in touch with him and later on I chose to complete my end of studies internship within OptimumG. Thinking about it now, this was probably the best start I could give to my racing career. Claude’s teaching skills made me understand very quickly and efficiently the basics of racing engineering. These notions learnt within OptimumG quickly became very sharp weapons to perform in the highly competitive world of international motorsport. Learning the basics and mostly understand how to apply them to solve practical problems on track is, to my point of view, what makes the difference when it comes to win races. I definitely recommend OptimumG for young and passionate engineers who wish to quickly fill up their racing engineering toolbox.”

Renaud Dufour, Motorsport engineering consultant, Lead engineer – AMG team Black Falcon

“My name is Carlos Caunedo, I’m an Argentinean mechanical engineer. In 2008, right after graduating from college, Claude gave me the opportunity to do an internship at OptimumG.

I was very passionate about motorsport but had little experience in the Racing World.

In OptimumG my main project was to develop and code the mathematical model for a vehicle dynamics simulation. OptimumG gave me the opportunity to follow the complete process between writing equations in a piece of paper and validating the simulation with real racecar information.

I had access to information that I had only seen in text books. Tyre data, data acquisition files including tire loads and slip angle, aeromaps and all the information needed to run a successful simulation. For the first time I was able to understand and quantify how each parameter would modify the vehicle dynamics.

After my internship I decided to go back to Argentina to work in motorsports. Thanks to the knowledge I acquired at OptimumG, I was able to develop in a short time a successful career in the Racing world.”
