and is almost always short, light, and female) lies down inside the vehicle with the steering and brake controls. The vehicles are completely unpowered, including the prohibition of energy storing devices such as flywheels. Brakes are required but generally rarely used. Often, brakes are applied only as a last resort to prevent a crash, or to slow the buggy at the finish for the pusher to catch up because the rules specify that the pusher must be in contact with buggy at the finish line or be disqualified. Drivers who have been forced to apply the brakes due to another driver cutting them off may appeal for a re-roll in another heat without penalty. The second-to-last corner of the race, a sharp 110-degree right turn, is affectionately called "The Chute" and is lined with hay bales to prevent potential driver and spectator injury. Speeds can be quite high in the chute, often in the vicinity of 35 mph. Student Dormitory Council (SDC) holds the current men's record of 2:02.16 and the current women's record of 2:23.27, both set in 2017. For many years extensive experimentation and innovation evolved buggy designs. Prior to 1980 the primary format used 4 wheels in a symmetrical layout with respect to the direction of travel. Exceptions to this did occur with both 3-wheeled buggies and 2-wheeled "bikes" being entered on occasion. Since 1980, new materials, braking systems and wheel orientations provided significant opportunity for experimentation. Alignment of wheels received particular attention. The first successful 3 wheeled buggies were developed in the early 80s led by Pi Kappa Alpha (PiKA) and Sigma Nu. Development of two wheeled buggies by Delta Upsilon from 1986–1989 continued the theme of wheel alignment. In 1988, Delta Upsilon broke the course record with a time of 2:08.5 a record that stood only briefly as SPIRIT surpassed that time later that day and further lowered the record time the following day. Two wheeled buggies were later eliminated from competition for safety reasons through modifications to the rules. PiKA and SPIRIT took every Sweepstakes championship from 1986 until 2000 when SDC won the women's race and 2001 when Fringe won the men's race. PiKA continued its success in the 2000s, setting the consecutive wins record by winning for seven years in a row (2002–2008). SDC took the title in the men's race in 2009 breaking PiKA's streak and setting a new record. Fringe
