The FIA has released its latest set of proposals on how Formula 1 will change from 2011 - and amongst the 'proposals' are plans to allow moving aerodynamic devices and adopt greener 'pump-legal bio-fuel'.

Although the changes outlined are not a 'definite statement of the FIA's position' and are 'intended to facilitate ongoing discussions' a number of themes, which keep cropping up, can be recognised including: improving the racing, making the sport more environmentally friendly, cutting costs, making it more relevant to future road car development and further improving safety.

The key proposals received in a report to the World Motor Sport Council include:

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 per cent 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 per cent 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.
