The concept scoring consisted of testing the reference design, the four group members’ designs, and the final AEV design with the success criteria. Each design was described and discussed in the design process (concept designs). The success criteria involved stability, cost, safety, coolness factor, aerodynamics, and power efficiency. Power efficiency was the criteria with the most importance or weight on the scoring. Power efficiency is how well the AEV uses the power given to it through the battery to move the AEV. The most power efficient AEV was predicted to be Hannah’s design and the final design. Both designs would use the least amount of power, while also producing the best results. Safety was the second most important criteria in the scoring. Safety consists of how well the AEV protects the passengers inside and how well it moves along the track without causing injuries. Safety also consists of the design that would potentially cause the least amount of damage to itself, the track, or any parts around it. The designs with the highest safety rating were Michael’s design and the final design. The third highest weighted criteria were a three-way tie between stability, coolness factor, and aerodynamics. Stability involved how well the AEV moves along the track without leaning to one side more than the other. It also consists of how well the AEV can hold the passengers without tipping so that they fall off. The AEV with the most stability would be the one that could handle adversity in things like wind and bumps while still staying upright and stable. The AEV designs that were considered the most stable were Michael’s design and the final AEV design. The coolness factor is a design criterion that involves the presentation of the AEV. This involves only the outside of the AEV and how it looks. The AEV color, shell design, and overall composure add to the coolness factor. The AEV designs with the highest scoring coolness factor were Maegan’s design and the final design. The aerodynamics of the AEV was also considered an important part of the concept scoring. The aerodynamics of the AEV was how well the design could go against wind and how well it could move through the air. The most aerodynamic designs were the ones that could cut through the air and push it aside. The aerodynamics also included how well the shell of the AEV was built. Typically, the more curved an object, the more aerodynamic it is. The AEV designs that were the most aerodynamic were Hannah and Michael’s designs and the final design. Lastly, the cost was the last part of the concept scoring, which also carried the least amount of weight. For the concept scoring, the group chose that the more the cost, the worse the score. The cost was determined by how expensive the parts in each design were and how much money it would take to build each design. The designs were all tied with the same score for the amount of money it would take to build them. The design with the best score was the reference AEV.
