The FIA has published an updated version of the 2010 F1 sporting regulations.

It adds many of the changes announced earlier such as the new ten-place points system and refuelling ban, as well as a few other small-but significant changes.

The testing restrictions will be even tighter in 2010 and drivers who perform mutliple engine changes in a weekend will now get extra penalties. Pit space – which will be at a premium next year – will now be allocated evenly between the teams.

The new changes include:

* Changes to how drivers are given time penalties after a race
* A reduction in the amount of one-day aerodynamic tests a team may conduct from eight to six
* Teams may now substitute aerodynamic test days for 24 hours of full-scale wind tunnel testing
* Teams which choose to bring in a driver with no prior F1 experience will be permitted an extra days’ testing on a non-calendar track
* A new clause stipulates that pit space will be allocated “on a strictly equal basis” – this space will be under pressure with the addition of new teams in 2010
* Teams are no longer allowed to use powered devices to lift the cars in the pit lane
* Although tyre warmers remain legal a new clause says the heating element may only act on the surface of the tyre
* There are new restrictions on how teams can test tyres
* Drivers who use two additional engines during a weekend will be moved back ten places on the grid at that race and the next one
* Drivers who get away slowly on the formation lap and cannot start from their designated starting position must start the race from the pit lane.
* During safety car periods drivers must lap slower than a designated lap time displayed in their cars
