Max Mosley, president of motorsport's governing body, is planning a major shake-up of Formula One.
Mosley will discuss his proposals with F1 team bosses next week
FIA president Mosley is proposing to introduce a number of radical changes in 2008 in a desperate bid to make the sport more competitive.
His proposals include fitting cars with smaller engines and banning power steering and automatic gearboxes.
The changes would also bring the cost of running a team down, allowing more teams to enter the championship.
F1 has faced increasing criticism that technological advances have turned races into processions, with too few cars on the grid having a realistic chance of winning.
The dominance of Ferrari and Michael Schumacher in recent years has also led to the sport losing popularity.
In a letter to team bosses, Mosley said the changes would "improve the racing spectacle without introducing artificial rules" and "put a greater emphasis on driver skills".
Among the proposals are:
- 2.4 litre V8 engines which must last two races (currently, 3 litre V10 engines to last race weekend)
- A return to manual gearboxes and a ban on traction control and power steering
- No tyre changes during race and one tyre supplier only
- 12 teams on grid (currently 10)
- No spare cars allowed during race weekend
The proposals have been sent to all 10 F1 team principals and will be discussed at a two-day conference in Monaco on 4 and 5 May.
