True, but an F1 car is on another level with 900+ hp (including ERS) at 740 kg with driver but not fuel.

I remember reading once they generate more a G of force just letting off the accelerator. Back in the day, Nigel Mansell had to leave for a few months for an injury. His next race back he retired because his neck muscles had lost conditioning despite working out every day.

Top Gear actually did that experiment too [0], and you are proven correct.

It’s in the downforce. Up to 6G sustained lateral cornering. That’s worse than fighter pilots, which have their Gs applied vertically.

My car has g-force sensors. I know from experience, it can only handle 1 lateral G before it starts to slide (in a 4-door sedan wrighing around 3500 lbs). Thats with Z-rated tires. What F1 and Indy cars can pull off is absolutely amazing. Most of what they can do is purely because of the aerodynamics and the insane downforce they produce. I remember hearing somewhere that an Indy car produces enough downforce at speed, it'd be able to drive upside down and stick to the inverted road.

Ok so why are there not upside down tracks in formula 1 this just seems like the obvious next step.

Imagine the leader car having any kind of issue at all, thus bringing the pack to a stop. The lift would disappear and everyone would fall to the ground. With nets it might be quite a spectacle but still safe!

It would make an already dangerous sport even more dangerous. Also, just because it may be theoretically possible it doesn't mean it is practically achievable. Think about what would happen if the driver can't approach the loop that turns the car upside down with enough speed, or within the angle range that's needed for the car to stay on it because of another car, or some problem... Basically any small mistake would be fatal.

Seems like some would have done it as a stunt at least, for sure. I agree with you that having it in an actual race would be infeasible.

Because you'd have to ensure you're going a minimum speed before that section of track.

Means you can't continue I'd you're slowed down for a yellow flag or someone threw you off your line.

The physics works, it just doesn't add to the race other than spectacle.

We should just go full Trackmania

I would pay to watch a remote-piloted robotic Trackmania if there were good enough systems to transfer track feel to the remote controls.

I hope 0G F1 racing becomes a thing in the space age (basically in space but in an arena filled with air where the only force that keeps the cars from floating is the downforce). Imagine roads at any angle!

You see it on the necks of the Formula 1 drivers, they're quite massive. Doesn't come for free of course, some hard work-outs behind that: https://youtu.be/t0SoPeY8zE8?t=67

My bike has a power to weight ratio of 1000ps per ton.
