 More new technical regulations proposed for 2013
 
This is a report on the BBC F1 site, but not (yet) on Autosport or F1.com, so for now I suggest we take it with a pinch of salt.

"F1 cars set for major changes inspired by Head & Byrne" http://news.bbc.co.uk/sport1/hi/motorsp ... 307861.stm

Formula 1 cars are set for more radical changes in time for 2013 as bosses look to make the sport more efficient and potentially more exciting.

Cars will have much smaller wings and specially-shaped underfloors designed to generate downforce differently.

They will use 35% less fuel and be a little slower but more challenging to drive, although passing may be easier.

Drawn up by respected engineers Patrick Head and Rory Byrne, the rules would be the biggest design change since 1983.

The draft regulations, which were requested by governing body the FIA, are to be sent to teams this week ahead of a meeting in January of F1's Technical Working Group (TWG), which scopes out rule changes.

The TWG, which includes the design heads of each team, will discuss the proposals and suggest any changes they feel might need to be made.

But the fundamental philosophy that has been created is expected to remain intact.

The major changes will be:

* Much smaller front and rear wings;

* A far greater proportion of the total downforce of the cars will be created by the underfloor, compared to the wings;

* A major reduction in the amount of total downforce created by the car;

* To achieve this, the underfloor of the cars will be shaped along its length to generate downforce for the first time since the 1982 season - currently cars have bottoms that are flat between the wheels;

* The average proportion of a lap that a driver is able to spend on full throttle to be cut from 70% in 2010 to 50% in 2013;

* Tyres will remain large and chunky to ensure cornering speeds remain high.

Head, director of engineering for Williams, and Byrne, a former chief designer for Ferrari, have between them been involved in the design of cars that have won 17 constructors' titles for Williams, Benetton and Ferrari.

The pair started work on the new rules in March and have now presented a set of draft regulations to FIA race director Charlie Whiting, who will finalise them before sending them off to the teams.

"We are only going to have roughly 65% of the amount of fuel and a [limited] fuel [flow] rate - that was a given," said Head, talking exclusively to BBC Sport.

"We were just told 'That's what it will be, you've got to come up with a car spec that is not going to be more than five seconds a lap slower than a current F1 car'.

"So some circuit simulation was done by Rory at Ferrari and when we'd come up with some numbers in terms of drag and downforce it was then to try to come up with a geometry of a car that could try to achieve that."

Head and Byrne were charged with ensuring the new rules did not make overtaking any harder and, as it turns out, they could actually make passing easier.

That is because a car should lose less downforce when it is following another car if more of its total downforce is created by its underfloor rather than its wings.

This makes it easier for drivers to follow closely behind cars they are racing and therefore easier to pass.

Shaped undersides were banned in F1 at the end of the 1982 season because it was felt cornering speeds had got too fast and the cars too dangerous.

But back then they were used with skirts that touched the ground and sealed the low-pressure area, vastly increasing its efficiency.

This will be made impossible in 2013 by making the centre of the car lower than the sides.

Do you want closer racing or a better technical spectacle? It really does depend on that and in my opinion you can't balance both and be better than having one side over the other.

I lost count of the number of times this year that Martin Brundle speculated about JB's driving style possibly allowing him to stay on soft tyres longer,

The benefit of that driving style was negated by the need to come in for a compulsory pitstop, and use both tyre compounds.

A driver like JB should have the freedom to do the whole race on softs, possibly pitting only once while another driver who is also running the whole race on softs has to pit twice.
Would either be faster than a driver running on hards but not pitting?

Who knows - this is the strategic "chess game" element that has been wished for earlier in this thread, with no need for a costly tyre war, just a simple (and free!) rule change.

Why wouldn't you do it?

Maybe F1 is actually not too bad as it is ;-)

I agree but they are overhauling it and I disagree with that.

They're only switching from wings to floor driven aerodynamics, they're not restricting development with these rules and I'm sure they'll claw back much of the lost downforce.

The 2009 and 2010 rules did far more of that (still can't believe they have to use Bahrain-level air filters for the rest of the season.)

I think they are meddling with the wrong things. That is the whole basis of my rants :).

Did they have the same spec air filters all year? Those Bahrain ones even filter most of the air out!

Yes! It's mad isn't it?
I only realised when one of the teams said that Yas Marina can be a bit dusty but as it's cooler and they'll be using the homologated filters designed to cope with Bahrain where nobody had any problems, everything should be okay...

That's the 2011 rules, not the 2013 rules

Both. But I agree with you that it's almost impossible to achieve.
