McHenry Consultants, Inc.( MCI) is an accident/collision investigation/reconstrucution company formed in 1980 by Raymond R. McHenry and Brian G. McHenry. MCI specializes in the investigation and reconstruction of highway accidents which has included the development, refinement and utilization of computer programs.
For over 35 years McHenry Consultants has continued research and development of computer models related to accident reconstruction. McHenry Consultants are experts in the state-of-the art of computer modeling and in particular the following areas: Accident Reconstruction, Vehicle Dynamics, Automotive Engineering and Occupant Kinematics.
McHenry Consultants has investigated and reconstructed over a 1000 accidents since 1980 and has staff available to investigate and reconstruct any type of motor vehicle crash including those involving cars, trucks, motorcycles and/or pedestrians. We have a staff of consultants, accident investigators, reconstructionists and Professional Engineers, located in North Carolina and throughout the country who can quickly respond to your case file needs.
In 2017 Brian G. McHenry was hired by Jaguar UK to design the 2018 Jaguar E-Pace Rollover Stunt. McHenry used computer simulation to modify the original spiral jump stunt for the 2018 Jaguar E-Pace vehicle. The stunt was where the 2018 Jaguar E-Pace was driven by a stunt driver up a ramp and rolled 360 degrees and landed on its wheels and continued driving down the road.
In 1998, Brian G. McHenry was hired by CBS News to reconstruct the Princess Di accident for the television program “48 Hours” where he presented results and answered questions in interviews broadcast on June 11, 1998 and August 31, 1998.
The First Astro Spiral Jump is an auto stunt invented and designed in 1974 by Raymond R. McHenry [US Patent No. 3,814,021] that was also produced in James Bond Movie.
McHenry Consultants are experts in the state-of-the art of computer modeling and in particular any of the following computer programs for Accident Reconstruction, Vehicle Dynamics and Occupant Kinematics:
