Harry Pearce, P.E.
Managing Engineer
Vehicle Engineering
  • Detroit

Mr. Pearce specializes in the analysis of mechanical systems. His automotive work has focused on crashworthiness, accident reconstruction, automotive structures, vehicle sealing, fuel systems, seatbelts, seats, windows/glazing and regulators, diesel engines, Engine Control Modules (ECM), motorcycle Anti-Lock Braking Systems (ABS), and exterior systems. He has conducted investigations of full frontal, small offset frontal, moderate offset frontal, side, rear, rollover/roof crush, wheel-off, and unintended acceleration collisions. He previously worked at GM for nine years as a lead structural engineer.

With his knowledge and experience with vehicle sealing, Mr. Pearce has addressed claims of Carbon Monoxide (CO) intrusion and battery off-gassing/explosion. He has performed Electro Magnetic Interference (EMI) testing and Brake Override System (BOS) testing. Mr. Pearce assesses the safety of automobiles with simple, detailed explanations of all Federal Motor Vehicle Safety Standards (FMVSS) including 208-front, 214-side, 201-interior, 301-fuel, 216-roof, and consumer metrics including: Insurance Institute for Highway Safety (IIHS) small offset, moderate offset, side, rear, and roof; front and side New Car Assessment Program (NCAP), and Highway Loss Data Institute (HLDI). Mr. Pearce’s fuel system experience includes tank location, material, shielding, pipe routing, Finite Element Analysis (FEA), and GM’s fire research. Mr. Pearce is knowledgeable on the implementation of vehicle technologies and has developed efficient methods to survey the entire vehicle fleet. He has conducted vehicle testing at Exponent’s Phoenix test track. In the area of accident reconstruction, Mr. Pearce has conducted site inspections, vehicle inspections, photogrammetry, momentum and energy analyses, and computer simulations. 

Mr. Pearce has done extensive analysis and testing on non-automotive mechanical systems as well, including home appliances and pipe fractures. He is experienced with liquid and air flow visualization within appliances. He is experienced with metallurgical aspects of plumbing water leaks.

Mr. Pearce has conducted extensive data analysis, including National Automotive Sampling System (NASS), warranty, and complaint data. He is experienced in: the acquisition of all types and ages of automotive parts; photography and HD/4K video acquisition, editing, and presentation; Computer Aided Design (CAD), FARO arm, FARO laser, and Mantis scanning; material testing; and component testing.

Prior to joining Exponent, Mr. Pearce held several lead design engineer positions during his nine years at General Motors. Most recently, Mr. Pearce was the Upper Structure Lead Design Engineer for the Buick Enclave, Chevrolet Traverse, and GMC Acadia midsize crossovers. He was also chairman of the product development teams responsible for all aspects of the vehicle development process. Mr. Pearce was responsible for the release of math models for analytical validation and the construction of prototype vehicles for physical validation. Mr. Pearce has worked in assembly plants and is experienced with the manufacturing process from part stamping to final vehicle assembly. Mr. Pearce has extensive knowledge of the vehicle development process from initial design concept to production. He is well-versed in the engineering of the body to meet the multitude of vehicle requirements including roof crush, crashworthiness, durability, and metal forming. He is knowledgeable in materials selection, including the use of high strength steels and weld placement.
