This paper describes the process of designing, building, and racing a high performance electric motorcycle for the 2011 Isle of Man Tourist Trophy (TT) Zero race. The TT race is the oldest existing motorcycle race (est. 1907), and is known for high speeds, over 200 sharp turns, and danger to the rider. These demands created a challenge to engineer a machine that was capable of finishing the entire course on a single battery charge in the fastest time possible. The design process consisted of systems engineering, subsystem design, final system design, testing, and model validation. Simulations were useful for understanding how the design parameters affect performance metrics. "Full throttle" simulations were performed to estimate the maximum acceleration, speed, and power of the motorcycle. To estimate the energy required to traverse the entire course, it is necessary to make assumptions about the throttle profile, speed, or power. Since it was difficult to predict the throttle profile for the entire race, both constant speed and constant power drive cycles were assumed. The electrical and mechanical designs of the motorcycle used mostly off-the-shelf components, though custom designs were generated for the instrumentation, motor shaft and structural frame that housed the motors and batteries. Real-time sensing provided a rich data set that was used to validate the models; it was found that the models were able to predict the acceleration, maximum speed, and energy consumption to within 5% of the actual values. Finally, guidelines for designing innovative zero emission races were presented and described. In this paper innovation was defined as the act of generating a product or service that (1) reduces the environmental impact of vehicles and (2) consumers want to purchase. The guidelines suggest to consider the historical context, utilize the power of regulation, drive technology, provide valued entertainment, and inspire consumer demand.
