[PDC] Political Design Challenge Rond 6: D.E.C.O.Y

Spain- 1974:

After almost forty years of tiranny, the dictator´s health is falling apart. Meanwhile, the enemies of the regime are gaining strength and the popular support is decreasing. But some people havn’t given up yet. The heads of the state still believe in the perpetuation of the dictatorial system, even after 'Paco’s death.

To do so, they need to keep the population away from politics. Football used to be the answer. But now that they are facing a significant problem, they go directly to the national carmaker with a mission:

They want to introduce a flamboyant new sports car, produced nationally. A cheap car, accesible for the common people, but at the same time a good performer, because the mysterious Mr. B is looking to fund a single make race cup for it:

I doubt it’s validity for racing though

Loving this new PDC!

Is there any guidance on displacement, or is it just whatever happens to work with the budgetary constraints and the six-cyclinder max?

Does that mean that regular alloy wheels are also taboo?

Also, I don’t think catalytic converters will be required - those would not be mandated until the mid-80s.

Addendum: I just found out that alloy wheels are allowed, but any panel material other than any kind of steel isn’t.

The low running costs mean your wheels won’t be thick enough for anything over 2L, but feel free to try your 10L inline 6 in this competition

The dictator didn’t believe in global warming

You can use alloy wheels. Those restraints were for the panels.

92 RON is leaded so your cats would burn out on the start line! :rofl:

Yeah I changed it over to specify alloy construction.
Again, displacement is really up to you, but most viable bodies naturally constrain it.
But where did you find catalytic converters mentioned? I didn’t put anything down. I don’t even think there’s the option to…

:rofl: Don’t worry, I wasn’t going to. I did have something over 2L that I think the wheels can handle… will need to sense-check it on the other side of sleep. :stuck_out_tongue:

(Can confirm that there’s no cat option with the leaded fuel, as should be the case.)

So, Still not send?

It wasn’t law in the US in '74.

Can I make a car called the “We’ve got all your fish”?

I’m not convinced, sounds like bait to me… but go ahead d:

I think two weeks for submissions are normal, right?
