High Mileage Vehicle
This is a fuel efficiency contest. Winners will be determined by the number of laps covered with an equivalent amount of energy.
- Fossil Fuel
- Hybrid , gas-electric or diesel electric
- Zero Emissions
- Safety Requirements:
- Structural Stability- Car must not tip if placed sideways on a fifteen degree incline with driver in cockpit.
- Driver must be shielded from all power transfer components within reasonable reach of the cockpit.
- No fuel leaks
- Two kill switches required. One must be easily accessible to the driver and the other must be easily accessible to the pit crew. Switches should be clearly marked with red. Enclosed cars shall have a kill switch that is accessible from outside the car.
- Drivers must have clear vision to an angle 90 degrees to the left and right. If drivers cannot clearly see to the left and right mirrors are required.
- Enclosed cars must have the engine compartment separated from the cockpit by a metal fire wall.
- Each car shall have a fire extinguisher easily accessible to the driver. Each pit crew must also have a fire extinguisher.
- No vehicle shall weigh over 550 pounds.
- No vehicle shall operate on over 56 volts
- The driver shall be able to exit the car in less than 15 seconds
- All cars shall have brakes that will stop the car in a reasonable distance
- All vehicles will be able to set stationary with the engine running and be able to accelerate from a stop without assistance.
- Energy/Fuel criteria
- All cars will be using en equivalent of 2616 Btu of energy
- For electric cars this is equivalent to a 40 LB (Group 24) lead acid battery. Any combination of lead acid batteries equaling 40 Lbs can be used as long as the voltage does not exceed the safety limit of 56 volts. All batteries will be weighed by the team operating the vehicle and the weight will be clearly marked on the battery.
- Gasoline vehicles will receive 79 CC of fuel
- Diesel Vehicles will receive 71 CC of fuel
- Two options are available for hybrid vehicles.
- Option one: Start with 40 Lbs of lead acid batteries and 71 CC of Diesel or 79 CC of gas. This gives them two times the available energy of the other cars so the total laps covered will be divided by two to determine placing
- Option two: Start with forty Lbs of lead acid battery and either 71 cc of diesel or 79 cc of gasoline. End contest with same state of battery charge as was available at the start of the contest. A penalty of 25% of the batteries BTU equivalent will be assessed for every .2 volts under 12.6 volts at the end of the contest.
- If other types of batteries are to be used the team must show a rating from a reputable source that indicates an equivalent of 2616 BTU total output from the battery or battery pack.
- Electric cars will be equipped with a watt meter and then run for thirty minutes. The meter reading then would be used to determine the winner.
- Driver Requirements
- DOT or Snell Approved Crash Helmet
- Eye Protection
- Appropriate Clothing and closed shoes (no sandals)
- Be a registered SkillsUSA member

The Novice/Intermediate welding contest gives students the opportunity to compete at the Wyoming SkillsUSA Leadership and Skills Conference. This is a State Only Contest. Winners are not eligible to move on to the National conference. Students are given a simplified print and should be able to perform the following processes. Generally, the Novice level is for freshman/sophomore or students that are in their first year of a welding program. The intermediate level is generally for sophomore/junior or students that are in the second part/year of a welding program.

Demonstrate safety procedures for SMAW
Demonstrate ability to correctly set up SMAW power sources, related welding equipment and do basic process and equipment troubleshooting for welding of carbon steel and/or stainless steel
Select correct type of electrode based on carbon steel and/or stainless steel plate (1/4" to 1/2" thickness)
