The Mechanical Presentation is focused on mechanical team engineering activity during Year 4, which includes the optimization and refinement of various systems: ESS, driveline components, thermal system, powertrain mounts, overall packaging, fuel system, etc. The team’s Mechanical Presentation should summarize this activity for Year 4 while emphasizing one major system of their design in detail. Teams should also discuss their team goals, engineering methodology and progress in meeting milestones. They should frame the vehicle refinement in the context of the engineering process and illustrate how sound engineering methodology was applied to the optimization and refinement process.
