- Vehicle drawbar testing was conducted in order to establish the relative performance of all wheel drive electric and viscous clutch transfer case systems. The drawbar tests of a Ford Aerostar system with an electric clutch transfer case are compared to viscous clutch systems in a GM Astro and a Chrysler Grand Cherokee. The empirical test results and theoretical comparison show that the electric clutch transfer case system has a greater amount of torque transfer and its reaction time is faster.
