- 1993: Clemson mechanical engineering students win a $1,500 prize in the Clean Air Vehicle Association (CAVA) Grand Prix Conference and Exposition in Atlanta when their electric car places first for design paper, second overall and second for performance. Seventeen undergraduates redesigned and rebuilt a 1980 Volkswagen Rabbit for the competition, converting it to electrical power, everything but the body being redone for the contest. The electric motor, controller and batteries were provided by their manufacturers through CAVA. Special safety devices had to be installed, including a roll cage and an emergency switch that can disconnect all power to the motor. The students substituted a five-speed transmission for the standard 4-speed. They redesigned the suspension for improved handling. "This conversion process was totally student designed, driven and managed," said Amit Bagchi, assistant professor of mechanical engineering and the students' faculty advisor. David Wilkerson was executive coordinator of the student group, called Clemson Alternative Automotive Technology. Student team leaders included Brad Merritt, the electrical group; Nitin Shanbhag, the mechanical group; Brad Golden, the group coordinating electrical and mechanical aspects of design; and Edie Johnson, publicity and fund raising. The Clean Air Vehicle Association and Manheim Auctions provided Clemson with the VW. Major sponsors for the entry included General Electric, Goodyear and Trojan Batteries. The department of mechanical engineering provided funding, and engineering services provided technical assistance and facilities. Other sponsors included Automotive Performance Systems, Troppo Veloce Restorations, I/O Port Racing Supplies and REBO Machining. (Clemson World News, August 1993, Volume 15, Number 2, page 5.)
