Rule 6.7 Buggy Restrictions
- No buggy may have any device whose purpose is to store energy independent of the speed of the buggy (such as a geared flywheel) or whose purpose is to increase the forward speed of that buggy by adding kinetic energy to that buggy.
- No buggy may have any means of internal propulsion.
- No buggy may have any type of protrusion (such as a sharp and/or pointed structure) extending from that buggy which could increase the likelihood of injury to the driver of another buggy in the event of an accident. The nose/tail of a buggy should be parabolic and not come to a point. If it were a curve, the derivative of any point on that curve should be defined across the whole length. This prohibits nose and tails that come to a point in three or two dimensions (i.e. a true point or an edge.) An allowed exception to this would be flat or cut-off tails, though the flat face must form an angle between 45 and 90 degrees to the ground. The minimum radius of curvature permitted for any nose or tail is .75. Final discretion as to what might be considered overly pointy is up to the discretion of the Safety Chairman.
- No buggy may be designed such that it would intentionally have less than three wheels in contact with the ground whenever it is on the buggy course.
