The GM/U-M Institute of Automotive Research and Education exhibit illustrates the connection between research, education and economic development. Four College of Engineering labs featured in this exhibit are: Advanced Battery Coalition for Drivetrains, Advanced Vehicle Manufacturing, Engine Systems, and Smart Materials and Structures. A Chevy Volt (the battery-powered, plug-in vehicle scheduled to go on sale next year) chassis is on display. Also on display is a Cadillac CTS that's part of a project to incorporate smart materials – substances that can sense changes in the environment and respond to them – into new vehicles.
