It would be awesome if they would implement a crude rule: no computers. You can use a computer to design the car--CAD/CAM/CAE are all fine--but no stored program computers are allowed in the race car. I think that would improve F1 tremendously.

Very funny idea. That basically means a carbureted gas engine, or a direct injection diesel with a mechanical governor and mechanically timed injection pumps - can't run a direct injection gas engine without a digital engine control unit, because the injection timings are much to precise to do mechanically.

So, basically '60s Formula 1. Might be fun to watch. We'd certainly see some crazy engine designs and a lot of re-fueling pit stops...

This is not accurate, the first production direct injection gasoline automotive engine was in the 1954 Mercedes-Benz 300SL. It's true, you probably won't be running piezoelectric injectors without computer controls, but there's nothing preventing direct injection.

But that would make it interesting. How many of the advances we've made in the past 75yrs could be accomplished some other way if you take the computer away? You don't need a computer to accomplish nanosecond timing. Maybe there's a clever analog way to run piezoelectric injectors.

[jcgrillo]

To phrase it maybe a little more provocatively: how would you accomplish the precise timing necessary to achieve spherical implosion? This was possible with analog electronics in 1945. Surely in 2026 we can also build analog piezoelectric fuel injection systems.

To play devil's advocate, this starts to get into the territory of, how do you define a computer? If the analog circuitry is using sensors and passive components to inject fuel at spark at just the right time under varying conditions, "computing" them, one might say...

Maybe "no integrated circuits" might be a finer line.

A stored program computer, that is a device which can run arbitrary programs from storage, is a pretty rigorously defined thing. Like, we all have a pretty clear shared understanding that things like FPGAs and microcontrollers are computers, whereas you can have integrated circuits which don't have these capabilities.

To be clear, I don't think making elaborate analog ICs would be really "cheating" so long as they don't put a generic von Neumann machine on it.

EDIT: to be more clear, what I'd be trying to achieve with a rule change like this is making "computation" a somewhat larger investment in time and difficulty. By and large, at least in my opinion, profligate, non-essential computation has enabled many of the things that have made the sport less interesting. It's also made cars suck a lot. This would impose kind of a tax on those things.

Most F1 fans have an opinion on F1 regulations. I like your take.

I want to see F1 car design be about function/performance above all. I want to see awesome gadgets using insanely clever design. Then ideally that design should influence built items in the rest of the world.

F1 used to be influential in creating and developing high technology. Now it seems to be about gathering high technology from elsewhere so as to meet the insane regulations most efficiently.
