Applied Vehicle Dynamics

While a variety of new engineering methods are becoming available to assist in creating optimal vehicle designs, subjective evaluation of vehicle dynamics is still required to deliver desired braking, handling, and acceleration attributes. In order to better prepare today’s engineer for this task, this course offers modules devoted to twelve key fundamental principles associated with longitudinal and lateral vehicle dynamics. Each focused classroom session is paired with an on-track exercise to immediately reinforce these concepts with a dedicated behind-the-wheel driving session, effectively illustrating these principles in the real world.

This seminar, in partnership with the BMW Performance Driving Centers in Greer, SC and Thermal, CA has been the leader in the industry since 2004; training automotive engineers as well as the training the trainers at leading engineering firms worldwide. 

Note that unlike most driving schools, this course is not designed to train performance drivers. Rather, the exercises on days one and two build the bridge between vehicle dynamics theory and practical application by providing a rich academic underpinning and then reinforcing it with highly focused and relevant driving experiences.

Significant technical skill-building is provided on day three, with increased instructor-supervised track time to further absorb the principles learned on days one and two. If your job description does require performance driving skills, the dynamic exercises on day three will lay a solid foundation on which you can independently refine your own skills.

This course has been approved by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) for 24 Continuing Education Units (CEUs). Upon completion of this seminar, accredited reconstructionists should mail a copy of their course certificate and the $5 student CEU fee to ACTAR, PO Box 1493, North Platte, NE 69103.
