Doug Fehan, program manager for Corvette Racing, talked like an evangelist for endurance racing Tuesday evening at Lanier Technical College’s motorsports vehicle technology class. Fehan, who is here for the Petit Le Mans that will be run at Road Atlanta Saturday, encouraged the class members to seek racing careers — if they have the work ethic and passion for it. He talked about Le Mans, the 24-hour endurance race in France as the pinnacle of racing.
