Extra wheel tethers from 2011

[Just_a_fan]

Surely we need less durable tyres? I want to see drivers struggling to keep the car on track. I want to see tortoise & hare scenarios, with one team going for 3 sets in a race, the other trying to make 2 sets last the duration of the race.

If we had everlasting tyres and no refuelling, then we would have no pit stops, no variability, the race would be over after the first lap.

Indeed. A single tyre specification that is marginal for the whole race is what is required. Think of Mansell chasing down Senna at Monaco (and Piquet at Silverstone) as an example of how the driver who makes a late change can suddenly ignite a race.

An alternative is to allow tyres to be changed and refuelling to be done but not in the same pitstop. That would throw some interesting tactics in to play...

Extra wheel tethers from 2011

Very wise decision. We've had too many flying wheels this season. In my opinion the rules should define more precisely where the tethers have to be fastened to. Mounting them "somewhere to the upright" isn't good as the uprights break too easily as we saw clearly in the Buemi's China adventure. It should be fastened somewhere close to the wheel bearing.

No wheel tether will be capable of keeping the wheel on the car in a crash completely. There is no way to connect the wheel to the chassis in anycase, it is the hub that is tethered. It is designed to absorb energy, hopefuly enough to allow the wheel to only disconnect with little energy left. No tether is possible to keep a wheel on the car if the wheel nut is not fastened properly.

It should be possible to develop a wheel hub/nut locking mechanism that sends a signal (radio?)to a receiver on the car that only allows clutch apply if all four wheel locks show locked.
I would think this is fairly strait forward.

I agree with you but Buemi had no crash at all, his suspension just collapsed. And wheels fell off just like there were no tethers even though there was no impact.

CLEAN UP THE CAR FOR A START,i DID TAKE NOTE THE V6 Turbo was mention,very clean look that car.
The Renaut,bt 48,49.Those designs alow much closer diceing.we have none of that now.
gee wiz I can't to tight on car infront of me,cause Ill over heat,an cook the power plant.
The show is deal,(In The Words of P.T.Barnum the show must go on)Empty seats will play well.
Why do we need wait,for these tec/regs and hope that somthing good comes from this.
Of course the Regs have caused the cars to look the way they do.Fed back is welcom.

What??? You mean re-introduce traction control? Get real!

That has nothing to do with TC! He is talking about an electronic immobilizer using wireless wheel nut torque sensors.

Cutting power to one wheel IS traction control! Any system that removes power to a wheel is traction control. Apart from that, cutting power to a loose wheel will not prevent it falling off, as the wheel would still be spinning!

For pit stops. If all four wheels aren't locked on then the car can't take off, thus eliminating accidents like Rosberg's.

It would prevent the wheel from falling off because the wheel would not spin on an immobilized car. The system is designed to work in pit stops to prevent the car to be driven off without properly fixed wheels.

Thank you.
How did traction control get into it?

Because you mentioned cutting power to a wheel!
