Bulletin 2012-09 FINAL UPDATE TO BULLETIN 5

BULLETIN No.: 2012 09
Subject: FINAL UPDATE TO BULLETIN 5

Issue Date: November 1, 2012

Bulletin 2012-09 en

The CARS Board of Directors has recently approved two further updates to the recent class changes announced in September. These changes address both concerns from competitors currently in Group 5, as well as refine the requirements for restrictors on small displacement, forced induction engines. The revised wording of these changes, as well as those announced in Bulletin 2012-08 are attached to this bulletin. A summary of the latest changes are as follows;

Production 2WD

- Forced induction engines will require a maximum air inlet diameter of 32mm or less. As previously announced, the maximum displacement for forced induction motors in this class is 1600cc.

Group 5

Section 12.7 - Group 5 regulations, will remain in force until December 31, 2014. This will allow competitors currently in Group 5 a period of time to make changes to their vehicles in order to comply with Open 2WD limits. Class prizes for Group 5 vehicles will continue to be awarded, however these vehicles will not be eligible for overall 2WD awards.

Subsequent to January 1, 2015, vehicles with engine displacements and/or forced induction restrictors greater than permitted in Open 2WD will still be allowed to compete at national rallies, however will be scored as Open 4WD class vehicles. These vehicles will need to comply with all other aspects of the Open 2WD regulations (ie NRR 12.6.4 to 12.6.6.1).

The Board of Directors of CARS has endorsed the four class system as the way forward for the growth of rallysport in Canada. The Canadian Rally Championship has enjoyed a high degree of success over the last two decades. The Board feels the new class regulations will address the changing nature of competitor, spectator and manufacturer demographics and help the sport continue to grow.

The Board also hopes that the recent updates to the rules, announced here and in bulletin 2012-08, highlight the open nature of the Association. Constructive and informed feedback from competitors is always welcome, and while CARS is committed to implementing the class changes, the Board is also willing to make modifications when sensible.

From a personal perspective, I would like to thank all the competitors and other interested parties who sent suggestions and comments to the Board. The result is undoubtedly a stronger and better rule set for Canadian rallysport.

As always, please feel free to contact either myself, your Regional Rally Director, the Technical Director, or your appropriate Board Representative if you have any further questions or comments.

 

Tom McGeer
President, Canadian Association of Rallysport.


12. ELIGIBILITY OF VEHICLES AND EQUIPMENT.

12.2 Definitions

12.2.2 Model.

A model is a basic manufacturer's designation (e.g.: Subaru Impreza, Volkswagen Golf, Ford Focus, Mitsubishi Lancer, etc...)

12.2.3 Model variant.

A model may exist in several variants as to bodywork (i.e.: 2 door sedan, 4 door sedan, coupe, station wagon etc.) or with regards to mechanical components. (e.g.: WRX, WRX Sti, etc.)

Original equipment is all items of standard or optional equipment that could have been ordered with the any particular bodywork variant of the model, installed on the factory production line, and delivered through a dealer in Canada. This does not include special orders, ‘one-offs’ or pre- production vehicles. Dealer installed options, except as required by manufacturer directives, (no matter how common) are not included in this definition
