On 27th June 2007, the World Motor Sport Council met in Paris to discuss the future of Formula 1. Having received a report on the status of the current discussions on the FIA Formula 1 World Championship from 2011, they have announced their new proposals:
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.
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 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.
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.
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.
