Huh!?
What's wrong with electric car racing? Electric race cars are already outperforming combustion engine vehicles in multiple arenas, just look at the current Pike's Peak record holder, or Nuremberg. Formula E is easily as exciting as F1. Extreme E races electric off road vehicles through the Amazon. Projekt E brings electric vehicles to top tier rally racing, there are many electric rally series. Pure ETCR is a GT racing series.

Do you miss the noise, or the smell? The racing is actually more exciting thanks to 100% torque at all speeds.

I think that at best this would be applicable only to the very lightest of electric vehicles (something in the "motorcycle" weight class, even half a ton is probably too heavy), and I have my doubts about even those, even when completely disregarding the sideways forces.

With a system like this you do not want more than a few cm (about an inch, at a guess) of suspension travel from when the car is lifted in air to the car at rest (= 1G vertical load), just from the weight of the car compressing the springs. If you have more the springs (which the loops naturally are) have to compress a lot with each revolution, which strains them, heats them, isn't good for rolling resistance, etc.

If we assume a 1000 kg car with a 50/50 weight distribution, to get about 2 cm of suspension travel the spring stiffness would be about comparable to a high level GT racing car. Comparing to high level sports cars, the street going Porsche 911 GT3 RS car, which is regarded as a pretty stiff, racy and track oriented vehicle has something in the region of three times that much travel, a normal commuter car can have way over 10 cm due to soft, comfort oriented springs.

So you can't spring a proper car with just these because it'd require it to be too stiff (also I can foresee shock absorption issues). Another problem is the 360 degree springy nature of it. You really don't want car tyres to move much aside from up and down. These have the problem that when you brake, the forces will try to push the axle forwards in relation to the wheel (i.e. the wheel moves backwards while braking), and the reverse when accelerating. You'd be (possibly) drastically changing the wheelbase of the car during acceleration and braking, which could have catastrophic results for handling in extreme situations. Many if not most cars these days are capable of braking at over 1 G, as long as they have decent tyres, so the front-back movement could be bigger than the up-down movement.

So yeah, doesn't really sound like a workable solution as the ONLY spring system on a car. Having some springiness in the tyres (either in the wheel itself of just having larger profile tyres, like we used to back in the day) can be helpful for comfort and even handling in some cases, but springing the car only via the wheels isn't a good idea, you really want to be able to control the wheels better than that.

Well apparently , the organisers of the Australian GP are threatening to sue because it wasn't loud enough. I remember as a kid hearing a formula 1 car in person when one did a demo lap in Dublin. The noise just blew me away, I had literally never heard anything that loud.

Personally, I think this kinda misses the point of F1. GT racing has always been more exciting because it's closer, but that's not why people watch F1. It should be about the best drivers racing the fastest cars. Yeah, the engineering is part of it. Bring back big engines, bring back ground effect, let's really see what the engineers can do.

F1 has always been as much about the technical aspect as the drivers.

And let's face it...Guitars, jet fighters, explosions.... loud things are just fucking awesome. .

I played this on my friend's Wii for about 3 hours, and though it was kinda weird at first getting used to the controls, after a little while you get used to it. I was surprised, I actually had a LOT of fun playing it. Though I don't think I'd want to play that way all the time. Also the graphics were a little better than I expected on the Wii considering the way some of the other games look on it, like this one GT racing game that had graphics so bad it looked like it had been ported from a Super Nintendo.
