Anyone know where the new rule book is? It seems later this year. We are just waiting on it to finalize all of our design. Seems like last years cam out beginning of August.

Yea, I think it was earlier last year. But this year they are focusing on a lot of fine details...like brake lights and such. As long as the inspectors can save time by not looking at brake lights, who cares how long you have to wait for the rules. Ha!

6 months should be plenty of time to build and test a car!

Don't forget to factor in design time to account for the new rules!

It's now posted- and looks like there are a slew of changes. Huge kudos to the techs for the new chassis pictures. Those will probably save hours in tech for new teams.

My interpretation of the revision to rule B15.1is that the entire primary cvt must be enclosed by aluminum or steel (not just the belt). Finally! That has been discussed here multiple times, and was probably the biggest safety issues with the rules. Glad that lesson didn't have to be learned the hard way!

Where did you Find that in the 2016 Rules? It is Part of the 2015 Rules under B3.2.2 but was removed and replaced with B3.7 Instrumentation and Data Acquisition for 2016

Oops. Looks like I was looking at 2015 rules instead.
Anybody have any more info on this? Moving to a totally different engine or updating the current design?

I was wondering the same thing. If I had to place a bet, I would say it's a Model 20 with newer emissions-related parts.

On page two under the partial list of updates is says B8.6.3 Document Response updated. I was about to comment here about how I couldn't find it but I think I realized the typo. Is it is meant to be B8.7.3?

"B15.1 Powertrain Guards NEW
... that rotate at the rate of the drive axle(s) or faster... Required Materials: Made of at least AISI 1010 strength steel at least 1.5 mm (0.06 in) thick – 16 Gauge is allowed. -OrMade of at least 6061 -T6 strength aluminum at least 3.0 mm (0.12 in) thick" So we need to have that guarding around our gears? Looks like this rule is going to add a few pounds to everyone's drivetrain...

Gears have always had to be guarded. You don't run them in open air do you?

I didn't pull up the rule book to see what changed but the thickness for aluminum guarding for your powertrain has always been .120" (last 4 years at least). Take a few pounds out of your gears or the rest of your car and you'll make up for it.

I guess it has been overlooked by us and the tech inspectors in the past, we have been running a plastic center section for about 4 years now

The material and thickness requirement for guarding is only around the periferals of the gears. You can have guarding on the sides that is plastic as long as it meets the finger protection rules. You've had your gears covered by something other than steel or aluminum and it has passed tech?
The rule change I believe is primarily looking at the use of completely carbon fiber or composite CVT covers that have not had the steel or aluminum guarding the clutches.

Yes, like i said before we have had a plastic center section. I have now looked at past years rules and we have just overlooked it. I'm surprised we got thru tech with it. I understand having the rule for the cvt, throwing a weight could definitely be dangerous. But for the gears i think that is overbuilt... If you compare a failing gear to a cvt throwing a weight, the gear is much easier to stop. I don't even think most atv's have a transmission housing that strong.

Link on the BajaSAE page isn't working but the direct link seems to be fine. 404 link is trying to direct me to a PDF dated 9.4.16.

It's not easy to machine aluminum to less than .125" thickness, and nearly impossible to cast it that thin without severe distortion. I agree with you that it is overbuilt for the failure mechanism that gears have, but the performance impact to teams is negligible. It is far simpler for the techs to enforce the rule as it is written than to have exceptions, valid or not. I doubt that any teams are running metal gearboxes that do not meet the rules for guarding, and if there are I would love to have a chat with their machinist to see how they combat chatter when machining.

The rule C3.10 Duplicate Design how did everyone interpret "significant" changes to a previously entered vehicle? We are thinking about redesigning the rear clip and implement trailing arms instead of a-arms.

We did that on our car between 2014 and 2015. That is a significant enough change for the design judges.
