Hotel & Travel Information
This seminar provides an introduction to the fundamental concepts and evolution of passenger car and light truck 4x4/all-wheel drive (AWD) systems including the nomenclature utilized to describe these systems. Basic power transfer unit and transfer case design parameters, component application to system function, the future of AWD systems, and emerging technologies that may enable future systems are covered.
This course is an excellent follow-up to the "A Familiarization of Drivetrain Components" seminar (which is designed for those who have limited experience with the total drivetrain).
By attending this seminar, you will be able to:
- Identify front wheel drive and rear wheel drive vehicle architectures
- Identify part time, full time, and on demand all-wheel drive systems
- Explain the benefits of all-wheel drive over two-wheel drive
- Quantify all wheel drive traction and mobility benefits
- Describe auxiliary axle disconnect systems
- Explain basic vehicle dynamics performance and the effect of AWD on
- Identify couplers vs. biasing devices and their basic function
- Describe the differences between mechanical and electrical implementation in
- Describe basic control strategies and logic
- Discuss advanced propulsion
concepts and systems
Who Should Attend
This seminar is designed for engineers (working with passenger cars, light trucks, and SUVs) who need to master AWD componentry, and the function and effect of those components. Engineers new to the 4WD/AWD field, as well as managers, marketing personnel, purchasing professionals and others interested in all-wheel drive fundamentals will benefit from this seminar.
A technical background in any discipline is beneficial, although not required.

"The course content exceeded my expectations and left me much more confident in my understanding of driveline systems."
"Although a complex topic, this seminar provided a one day overview of many of the latest devices in the automotive drivetrain arena that are currently in the market."
Steven J. Wesolowski
Director of Global Strategies
Senior Sales Engineer
"A good introduction to all-wheel-drive systems with good balance between theory and real-world experience."
Ford Motor Company
"This course saves at least several days to learn driveline technologies compared to self-desk research. In today's world where time is so valuable, the price of class is well worth it."
"A great overview of the AWD market and the systems and devices that are utilized."
