    OBJECTIVE: To design and build the lightest model vehicle that will protect two egg-people in a frontal collision with a concrete block. The styling and features that would make it an appealing choice aesthetically will also be judged.

    Base Vehicle: The instructor will provide the base chassis made out of hardwood. The base measures 1 ½ inches thick, 5 ½ inches wide, and 10 inches long. The base will have four skateboard wheels mounted to it. The expectation is students build the vehicle that will sit atop the base.

    Testing Surface: A ramp approximately 60” high and 100” long will be set up with a concrete block at the base as shown below. In the Frontal-Impact test, cars will begin at rest at the top of the ramp and roll down and collide with the concrete block.

    Eggs:  Two large eggs will be supplied by your instructor on competition day. The egg-person will model the driver and front seat passenger of the car.

    Allowable Materials:  Any commonly available materials may be used as long as no material will create a safety hazard, damage the ramp or concrete block, or make a mess that is difficult to clean. 

    Competition Format:

    • Static judging of the car’s construction
    • Styling of the car aesthetically
    • Features of the car restraint system
    • Results of the collision with the concrete block.


    Static Judging:      Each of the two static judging will be graded on a 0-100 point scale. The instructor will assess the cars from the point of view that they are a car buyer who is in the market for a safe, comfortable, and stylish car.

    Car Exterior: The exterior of the car will be judged on items such as construction quality, features present, and styling.

    Car Interior: The interior of the car will be judged for items such as construction quality, features present, roominess, driver and passenger visibility, ease of getting into and out of the seat, and restraints, perceived comfort of the seat and restraints, and overall inside styling.

    Collision Testing: If the instructor rules that the car is safe to test, it will first undergo the frontal crash by launching it at rest from the top of the ramp and then having it collide with the concrete block at the base of the ramp.


    A car will earn 0 points if:

    The car fails the pre-test inspection.
    Either egg breaks. An egg with a visible crack of any kind will be considered broken.
    Either egg is thrown out of the seat it was originally in during either test.
    The car body detaches from the base in either test.



    • On competition day, the mass of the body will be determined before the eggs are loaded and the cart is attached.
    • The car body must be securely attached to the wooden base using the two bolts and wing nuts supplied with the wooden base and remain attached after the collision.
    • No part of the car body may extend more than 3 inches in front of the wooden base.
    • The body may not touch the track or wheels.
    • The “Driver” and front seat “Passenger” egg people must be seated the same distance from the front of the car.
    • Vehicle bodies may not contain sharp edges or any components that will shatter.
    • Vehicle bodies must be constructed in a way to minimize the risk of components flying off the vehicle after collision.
    • Cars may not contain materials that are difficult to clean up after the collision.
    • Minor repairs may be made to the car after the frontal crash as long as they can be completed in less than five minutes. Winners would advance to the next round and crash their project again.
    • Any vehicle, which is judged as a safety hazard or may cause damage to the track, concrete block, or any other property, will not be allowed to be tested and will receive zero points for the collision test.
    • Each group’s project must represent a distinctly different design from one another. Cosmetic differences do not constitute a different design.



    Each Team Must:

    Build its own egg people using thin cardboard or matte board, please use the above drawing as a guide. Make sure egg people are between 5.3-5.4” tall


    OVERALL WINNER:  The car with the greatest point total for the static judging and collision test will be the winner.
