A new class for 2018 for cars that "go beyond what is allowed in modified class". Like tube chassis cars. 2wd or awd. Engine is limited to four cylinders or two rotors. Anybody have any plans for this? I think it could be ridiculously awesome. I was daydreaming about what would be a good build. Maybe an awd manual honda crv driveline on as small and light of a chassis as you could get away with and whatever is the hottest honda motor you can come with? Subaru buggy? This is gonna be great.
sounds awesome. I'd do a midlana with tractor tires. http://midlana.com/
Or maybe mix a ATV and a superbike.
I'll raise the obvious question-- other than needing windshield, roof and fenders/mudflaps, how many other body panels need to be added to this?
Some discussion in the side by sides rally thread make it seem like it has some really strange restrictions
The disallowing motorcyce/atv/utv motors was obviously added just to make it so side by sides are not legal despite them meeting almost all the other criteria

The scca autox does not allow non-car combustion engines either (except in A-mod). I think they are too light and too powerful compared to automotive engines. If you allow them, pretty soon everyone needs them.
I'm not really a fan of their stance, but I think that is why it is.

No non-automotive engines allowed. Also no open wheel allowed, and the driver must be encased in a tub.

Driver must sit in a tub, the rollcage must be Improved Touring compliant at a minimum, and the height of the top of the roll cage must not be any more than 75% of the track width, so you'd have to lower it as far as you could. Or increase track width.
It wouldn't meet the rollover requirements. They went very aggressive with those. I don't know that I've ever seen anything rallycross that would meet them. If you did a NA-based exocet at stock height, the top of the rollbar would need to be <42" off the ground. So 6" less than a stock NA
Edit: Doh. 90%. So roughly 50.25" to the top of the rollbar. A stock height exocet should pass. A 3" lift would likely not. One with tall tires like that picture would almost definitely not pass.

I think it said 90% as tall as the track width.
If they allowed motorcycle engines or relaxed the roll cage or relaxed the height restrictions, we could end up with any of these:
Legends car:
Sprint car: 
Formula cross:
Crosskart:
Autograss class 9
Instead, they are all explicitly banned by various bits of the rules. I am not really sure what car this class is for. The rules seem to be written for a single seater car that doesn't exist.
Remember that the existing modified rules are wide open. For example, you can take any car, cut off the front 2' of frame and make a tubular front subframe, cut off the back 2' of frame and make a tubular rear subframe, install any motor in the passenger seat, replace all body panels except the roof with fiberglass, and figure out how to get what is left of the body back onto the frame.
All the interesting stuff on the lifted Exocet can be put onto a miata with no fenders that is legal for modified without a cage. There are only a couple of purpose built modified rallycross cars in the country. Most of the really good drivers use it as a jumping off point for stage rally. At some point, someone is going to drop the money and time into something like the EMod MGB Loosecannon is building and run it in modified, not the new class.
Would this work?

E21s aren't exactly common but there are a few of them out there.
They are legal to run in any of the current classes depending on prep level. I would try to find an LSD that fits.
I thought Bike Engined Cars were legal in some mod classes of autocross besides amod?
But yeah the list above looks like a ton of awesome stuff and none of it is legal which is rather funny to me
Bike Engined cars are legal in modified but not the new class. I am waiting for someone to run an autograss twin engined Mini from the UK. Dual liter bike motors each powering two wheels should be fun to watch.

Bike engined cars are legal in Modified classes already. Just not the proposed Open class.
Modified is actually a VERY relaxed rulebook.

save yourself the difficulty of getting decent performance parts, suspension parts, and LSD......just get an e30. It's simply a better car in every respect (source: I've had both...)
In reply to irish44j:
Do E21s have floor-pivot pedals like 2002s did? Because if so that makes them better than E30s.
If not, then yeah, get an E30. Actually probably get an E36, they seem to be really good rallycross cars.
Still kinda want a '95 M3, too.
I was daydreaming about something like putting driveline out of say a saturn ion redline in the back of a tube chassis. Wikipedia wasnt real specific but it says they are 67 inches wide. Going off the 90% rule that means you could be 60 inches tall (unless the rule means center of the tire, then lets say 56") that seems like it wouldnt be tough at all to stay under that height. Its not rock crawling so you dont need a ton of ground clearance. That seems to me like a realistic build that would fall within the rules and be fast and light. Am i missing something?

Track width rules in autocross measure from center of tire, so yeah, it'll be annoying.
I think this is just stupid, just give them a side by side class already. There is a need for it and this is a great venue. maybe that would open the doors to some side by side league or something.
I see lots of videos on youtube of stuff like this
https://www.youtube.com/watch?v=yOSoGYoFGIE&t=810s
but there is no real national organization either. And these people are all over the place all over the country. Its a lot easier to transport one than a car etc
So there is at least one already popular, and growing more so every day, class of relatively affordable performance offroad vehicles in widespread use out there with no class to come run in...Thus the obvious choice was to make a new class that not only specifically excludes all of them, but in fact actually has NO existing vehicles to compete in it at all. 
The answer might just be NON SCCA needs to start doing it and then when SCCA realizes its missing out similar to what happened with CAM they will do something
I suspect I'd roll a SxS on some of the rallycross courses I've competed on.

we probably roll a car at least once a year here in the Detroit region, so what difference does it make?
