An update on the rule change proposal I posted a while back: from the feedback, it sounds like some aspects of these rules were confusing. Here are some images:
Area template:
The K4.1 area template is a single continuous shape which is coplanar with the rear face of the inner template. The area template must cover the entirety of the rear face of the inner template, must be at least 150,000mm^2 in area, and must be no more than 600mm wide and no more than 450mm high. This template must be entirely enclosed within the bodywork and must not intersect any other parts or templates.
The area template is a part that you create and include in the submission (it is in the list of parts at the start of the rulebook). What does everyone think about the 150,000mm^2 dimension? I think ideally we would make this larger, but there's not been any feedback on this point yet.
There was an addition to K4.1, regulating bodywork surrounding the outer template. I'm suggesting changing this slightly:
A line drawn from any point on the the outer template upwards or downwards may not intersect bodywork in both directions. It may intersect in one direction, or neither direction. This requirement is ignored for the first 200mm of the outer template. The front suspension templates are ignored for this requirement.
The 350mm rearward movement limit for the upper side impact structure could be changed to 400mm (or we could remove this template completely?), and the lower side impact structure will be removed as mentioned in the original proposal.
The other changes originally suggested:
- K4.2: Outlet must now be at least 1000mm rearwards of the inlet (+200mm). Last 200mm of outer template may intersect rear suspension templates. Inner template may intersect rear suspension templates.
- Split drivetrain template into upper/lower engine template and gearbox template. Together, these 3 parts are identical to the current drivetrain template. Rules which previously referred to 'drivetrain template' now refer to one or both of the engine templates. The gearbox template is just for bodywork to enclose.
In the interest of keeping the changes to a minimum, I think we should limit the drivetrain template split to be two pieces instead of three, by splitting it into an engine template and gearbox template. The upper and lower engine templates from the image I posted would be combined to form the engine template.
I am also suggesting that we change K4.2 so that the outer template is 900mm long rather than 1000mm, and the final 325mm of the outer template may intersect the rear suspension templates (to roughly follow the dimensions for the outer template for the cooling inlet).
Any more feedback on these suggestions? We should have a firm proposal out by around the 16th, which is when the vote will open.
