Greenpower USA F24 (Grades 6-12)
For middle and high school students completing the F24 build, the foundational skills learned through the Goblin program are built upon with the introduction of functional system changes such as tire composition and pressure, gear ratio changes, drive systems, weight reduction, and motor control.
In the process of implementing and evaluating the effectiveness of these changes, students learn that they must work together for their team to be successful. This concept is reinforced as the students begin to shift from teacher direction to student direction with teacher support and oversight.

Division Groups
Stock Division
A car will compete in the F24 Stock Division when it has been built using the materials given by Greenpower USA when the kit was delivered to your location. The Stock car must be built per the kit car manual except for the listed allowed modifications. The gearing system (6:1) supplied with the kit MUST be used in competition. Allowed modifications to remain in this division include: adding a heat sink to the motor, creating a custom steering wheel, installing a new safety harness, installing a new LED brake light, relocating the horn button, and installing tires that must have a sidewall PSI rating that cannot exceed 70 PSI. In addition, the measured PSI cannot exceed the maximum rating as noted on the sidewall of the tire.
Modified Division
A car will compete in the F24 Modified Division if it has made any modifications to the Greenpower USA kit. This includes, but is not limited to, tire improvements, gear/sprocket changes, controllers, etc. If a team has “stitch-drilled” holes in the chassis to reduce weight, Greenpower race officials reserve the right to deem the car unsafe from taking part in an event.
Custom Division
A car will compete in the F24 Custom Division if the chassis has been made from scratch. Teams wishing to compete in this division MUST submit a one-page persuasive argument for competing in this division. In addition to the one-page argument, proof of student involvement in the design and build stages must be provided via pictures, drawings, diagrams, etc.
Event Scoring
A Presentation Component and 90-minute Race Session are required at all sanctioned Greenpower USA F24 events. During the 90-minute Race Session, teams are not permitted to change batteries.
The Presentation Component is completed by distributing the rubric for each event to all registered teams via the Event Page. Historically, presentations have been delivered through PowerPoint, live interviews, video submissions, and more. These are scored by judges selected by the Event Organizer.
Each team must compete in at least one 90-minute session to be eligible for overall points. The goal for each team is to complete more laps than other teams competing in their classification (age and division).
The Overall Score is determined by adding scores from the Presentation judging and Racing performances together.
