Like the Corvette ZR1 and the CTS-V Coupe, the wagon is set up on magnetorheological dampers, which use micro-metallic particles in the dampers to vary viscosity according to the car's dynamic sensors.
Dr. David Faxon , chief of cardiology at University of Chicago Hospital and former president of the American Heart Association, began using the device earlier this year to determine the role viscosity may play in clogging or hardening arteries.
