The goal is to reduce the level of greenhouse gas emissions by recovering energy wasted during braking...

Quaint, but these are vehicles designed for the purposes of competitive racing, not everyday usage.

... they're burning petrol without reason

Wrong !
They are burning petrol to make money

No, they are burning petrol to research engineering methods and thus, on a collateral level, benefiting us, the consumers. What car manufacturer had that ad slogan "We race, you win"?

You're right, but engine design and refinement can still flow over into the creation of better, more efficient engines in road cars. However, if Moseley has his way, this will go backwards. F1 must remain at the forefront of motor vehicular development.

F1 cars .. let alone the normal road cars can go just as fast as todays fuel burning cars ......

India confirmed for the 2009 F1:
Planet F1:

India will host its first Formula One grand prix in two years' time, it has been announced.

The announcement, which was made by Indian Olympic Association (IOA) president Suresh Kalmadi, came on Thursday morning after months of negotiations with F1 supremo Bernie Ecclestone.

"We have received a letter in this regard from Bernie Ecclestone, CEO of Formula One. The IOA will be the promoter and the first event will be held in 2009," he told a news conference.

Kalmadi added that financing for the event would be raised through either government or private funding.

"Once we move ahead (put all aspects in place), a regular contract would be signed," Kalmadi added.

"We are planning to hold the race around New Delhi and we are looking to identify suitable land for a track."

Lets hope that F1 cars wont be electric powered by then.

The FIA have released proposals for changes to technical regulations that could herald a revolution in Formula 1 racing.

Following a meeting in Paris on Wednesday, the World Motorsport council released a statement regarding their plans to change technical specifications from the 2011 racing season.

Some of the key changes proposed are a potential 50% reduction in downforce and the legalisation of movable aerodynamic devices, something that is prohibited under current regulations.

It is hoped that these measures will encourage overtaking, as the leading car will exert far less physical influence on the car wishing to overtake.

The reason behind the proposals are myriad, with cost-cutting, the possibilty of closer racing and improved environmental friendliness amongst the key considerations behind the FIA's thinking.

There is also a perceived wish to make F1 technology more relevant to road car development.

Significantly advanced aerodynamic devices such as plasma generation, MEMS turbulators and shape-morphing are all mooted in the document which, should the proposals be accepted, is set to signal a revolution in F1 technology.

Here are some of the main proposals as outlined by the FIA:

Engine efficiency

To limit engine power by imposing a maximum energy flow rate. However, there will be few restrictions on the engine cycle, which can include turbo-charging and energy recovery. It is believed that this will lead to a gain of at least 20% in thermal efficiency.

Drag

To allow moving aerodynamic devices, which will reduce drag by over 50% and allow a 40% reduction in the power required to maintain current speeds.

Energy recovery

Energy will be recovered during braking and returned to both front and rear axles when accelerating. The amount of energy returned on each straight will be limited in order to prevent top speeds exceeding the safety criteria for the circuits.

Fuel

The total amount of fuel energy to be consumed during a race will be regulated, encouraging further overall efficiency. The CO2 emitted will be further reduced by the introduction of gasoline which is partly derived from sustainable, non-food bio sources but complies fully with pump fuel legislation.

Overtaking

Formula One cars currently find it very difficult to overtake because of the influence of the car in front. New aerodynamic rules will halve the downforce, and de-sensitise the car to the influence of the wake of the car ahead. It is also proposed to eliminate automatically the downforce deficit of the following car.

Regulations

The best estimates of what these measures will mean in terms of regulations are currently as follows:

# 1.3-1.5 litre, 4-cylinder engine;

# no RPM or boost limit;

# energy flow rate to generate 300kW, including energy recovery from the exhaust;

# 200kW brake energy recovery, front and rear axle;

# 400-600kJ energy return per straight;

# pump-legal bio-fuel;

# FIA specified and supplied undertray and possibly other aerodynamic components;

# 50% 2007 downforce;

# adjustable, regulated wings and cooling;

# automatic downforce adjustment when following another car;

# lap times and top speeds maintained at 2009 levels;

# over 50% reduction in fuel consumed.

Costs

A number of measures to constrain costs are proposed, including:

# standardisation of components;

# homologation of components and assemblies;

# material restrictions;

# extended life of assemblies;

# restrictions on personnel and work at races;

# restrictions on the use of certain facilities (eg wind tunnels).

All these measures will be developed into detailed regulations in close collaboration with the teams and manufacturers.

F1's governing body could legalise moveable aerodynamic devices in 2011, it emerged after a meeting on Wednesday of the FIA World Motor Sport Council in Paris.

Despite recent controversies over currently banned designs like overly flexible wings and floors, the FIA revealed in a statement that freeing up these regulations could 'reduce drag by over 50% and allow a 40% reduction in the power required to maintain current speeds.
'

Overtaking, meanwhile, could be stimulated by introducing new rules and standardised bodywork to 'halve the downforce', making it easier for the next car to follow and pass its rival, while V8s may be scrapped and replaced by four-cylinder engines.

Also mooted at the meeting were 'restrictions on personnel' at races and restrictions 'on the use of (wind tunnels)'.

That is a lot of freaking rules :shock:

Oh thats just great :roll: they may as well just have open wheel Prius races.

Another reason why I'm eventually going to stop watching F1 altogether

Well, 1.5 turbo might produce some healthy horses.

Since in missed the turbo era.
I love see some turbocharger f1 action myself.
And even if they run on bio fuel like bio etanol i think they will make more power on bio fuel than the normal fuel they use now,

Too bad that bio fuel produces fewer BTU's of energy per mole, and therefore isn't more power then the fuel they use now.
