TSA Middle and
High School Design Events


The middle school (Dragster Design Challenge) and high school (Dragster Design) competitions are similar in that student-built cars compete in a two-day race event that is modeled after big-time national drag racing events. Race performance, in addition to other criteria, determines the winner.

The Race
Cars are impounded by race officials prior to a time trial in which cars race against the clock. The cars that cover the 65-foot, 7.5-inch distance in the least amount of time are thoroughly checked against a rigid set of specifications. This spec list includes: minimum weight of 55 grams, numerous regulations regarding wheels and axles, and a host of minimum and maximum dimensions. Often, some of the fastest cars are disqualified because they are lighter than the minimum weight requirement. The fastest 16 cars that meet all of the specifications compete the following day in a double-elimination bracket showdown!

The bracket winners are assessed points based on their event placings (1st place — 50 points, 2nd place — 45 points, 3rd place — 40 pts, and so forth).


Other Criteria
Race competitors must also submit technical drawings of their cars, which are judged for accuracy and drawing skill. The technical drawings are an important part of the event. They account for as much as 25 of the 100 total points.


In addition, the cars are tested in a wind tunnel, and the competitors are assessed points based on their cars' aerodynamic efficiency.
