increase cornering speeds, decrease braking distances, etc... so no different to increasing aerodynamically induced downforce.

The current tyre dimensions are antiquated and do not directly relate to any part of the current day automotive industry let alone any other form of motorsport.

Tbh, F1 hardly invented anything in their history

I'm almost sure Audi uses a Williams based KERS system with it's flywheel as Porsche(in other words, VAG) sort of bought it from, or partnered with Frank's team some years ago and will also use it.

Also, Toyota already had road cars that recovered energy from braking earlier than F1 started using it in 2009.

Die Welt: Ferrari is in talks with Hulkenberg

Has no benefit? Anyone who thinks that is a complete moron! How do you test a component? Test it to it's limit. What's the best way to do that? Go racing. It's obvious. F1 has lessened this to an extent in the last 5-10 years, hence why less road car companies are involved in the sport. But point stands. It still has a massive benefit to road car manufacturers. However, Le Mans cars have arguably over taken F1 in developmental usefulness, but KERS technology and introduction of new regulations in 2014 will be a huge step forward. Turbo technology can go into the road cars from there. Diesel tech too.

Football doesn't have to justify itself because it has no technology. Aside from the players boots, clothes and the ball there isn't much more to develop. A car has 5000 components to develop.

Yes, this argument of F1 improving road cars only makes motorsport supporters lose any credibility.

It's sport, just a spectacle that has no use or benefit for society except as entertainment for its fans. Why do we always have to justify that our sport is useful while football for example never has to?

Pirelli cancels wider 2014 tyres

Despite ongoing uncertainty about who will be the tyre supplier for Formula One in 2014, Pirelli have confirmed that its plans to have wider rear tyres are now scrapped as teams opposed to the suggestion.

The Italian tyre manufacturer has confirmed by means of its motor sport boss that the size of its tyres will not be changing into the 2014 season. Pirelli suggested to increase the width of the rear tyres to cope with the additional torque of the 2014 turbo engines, but following a consultation round with teams this has now been cancelled.

Paul Hembery told Auto Motor und Sport that data supplied by one engine supplier in particular - widely believed to be Mercedes - was alarming. This seems to confirm earlier beliefs that the Mercedes V6 will be a lot more powerful in the beginning of 2014 than its competitors.

"Based on the information we have received from most of the teams, we have decided to keep the same tyre dimensions (in 2014)", Hembery said.

"But as the cars of next year will make very different demands of the tyres, we have proposed that the regulations be amended so that the teams may use different compounds front and rear, should it be necessary."

In an attempt not to extend the possible performance gap by allowing more rear grip from the tyres, rear tyre and dim dimensions will remain the same.
