2021 HORNET CLASS RULES 


The rules are designed to provide fair, entry level  competition and a high level of safety. The emphasis is on keeping this class of cars inexpensive to build as well as providing for the safety of the participants. It is the driver/owners responsibility to ensure his/her car is legal. If there is any question about rules contact the tech staff. 

Non-conforming cars will not be allowed to compete, except for minor variations, at tech discretion.



The 2021 season will see the Hornet class divided into 2 categories. The Hornet A group will be all cars that have faster than 17 second laps, but do not exceed 16 seconds. The Hornet B group will be all cars that have faster than 19 second laps, but do not exceed 17 seconds.  If a car exceeds the lap time of its declared grouping, that car has two options….1) Declare to move up to the next level 2)Take a 50 lbs. penalty for the remainder of the season…placed on the right side of the car, in the front seat passenger floor area.

Penticton Speedway may change the category A/B lap time brackets at anytime.

The final decision of the Track Officials and their interpretation of these rules will be the final ruling. These rules are designed to keep the Hornet class an entry level class.
