Gregg Peterson

Principal Materials Engineer

Throughout his 40+ year career, Gregory E. Peterson (Gregg) has embodied the true spirit of engineering innovation and excellence. An accomplished engineer, inventor, mentor of emerging talent, and successful entrepreneur, Gregg brings an impressive array of expertise and enthusiasm to every endeavor he pursues. 

Gregg’s OEM and Tier 1 automotive engineering experience spans more than 30 years and includes extensive ferrous and non-ferrous body structure design and innovation, aerodynamics, software controls, manufacturing/processing and more. He has also utilized carbon fiber for aerospace as well as a variety of non-automotive structural applications. Gregg also has more than 10 years of sales experience and substantial entrepreneurial involvement. In every role, Gregg has demonstrated superb leadership skills and an ability to heighten creativity in himself and others.

During his tenure at General Motors’ Advanced Engineering Vehicle Group, Gregg directed 20% of his department’s budget toward new technologies. As a Lotus Engineering representative, he was instrumental in technology transfer with NASA—successfully adapting software from the aerospace industry to automotive.

Another notable achievement is Gregg’s innovative thinking regarding commercial vehicle battery usage. He championed the idea that battery cost should be viewed in terms of $/lb. and that lightweight material use can reduce battery costs. Gregg’s unique logic points to a significant opportunity for the electric vehicle industry. In fact, he made several presentations at battery and electric vehicle conferences showing that it’s significantly more cost-effective to engineer lightweight electric vehicles using relatively expensive materials than to increase vehicle range by adding batteries. Fundamentally, reducing non-powertrain mass results in mass-decompounding whereas adding batteries results in mass compounding, i.e. adding batteries increases mass which typically requires a heavier body, suspension and powertrain to manage the added loads. Industry feedback (including Ferrari) from these presentations has been very positive. 

Gregg’s track record for redefining material usage is impressive, whether it involves replacing steel with lighter, alternative materials such as rubber and foam, or introducing new ways of manufacturing such as replacing stampings with highly integrated one piece castings. One of Gregg’s success stories was replacing steel with carbon fiber on a non-automotive project. The carbon fiber cost on a per pound basis was 16:1 (sixteen times more expensive than the baseline material). The lightweight design, 1/5 the weight of the baseline structure, reduced the parts count, tooling cost, assembly time and joining expenses and eliminated the  painting process. The cost difference went from 16:1 to 1.6:1, a factor of 10 for cost reduction. Additionally, this lightweight design allowed the use of much smaller, less expensive and more fuel efficient movers resulting in ancillary cost savings. 

Gregg has taught HVA/C system design graduate courses at Lawrence Technological University and developed an online lecture series for Automotive HVA/C and for Fundamentals of Lightweight Design (both available through Ohio State University). Additionally, he created a variety of technical classes for both designers and engineers. Gregg is also an SAE volunteer speaker who makes frequent presentations to university SAE chapters. 

Gregg holds 12 patents in multi-disciplinary fields, with more in process, and he earned a Bachelor of Science degree in Mechanical Engineering from the General Motors Institute.
