FIA FORMULA ONE WORLD CHAMPIONSHIP
Changes to the 2012 Technical Regulations
- All engine standard ECU set up and control parameters, which were formerly contained only within a Technical Directive, are now contained within the relevant parts of the Technical Regulations.
- The exhaust tailpipes are now strictly regulated in order to ensure that the aerodynamic effect exhaust gases have on the car is kept to an absolute minimum.
- Better marking of in-car emergency switches operated by marshals are now stipulated.
- The side impact structures will now have to be subjected to a further (upward) push-off test.
Changes to the 2012 Sporting Regulations
- Cars may no longer take part in pre-season testing without having passed all crash tests.
- There will now be a maximum race time of four hours to ensure that a lengthy suspension of a race does not result in a race that could run up to eight hours if left unregulated.
- Before the safety car returns to the pits all lapped cars will be allowed to unlap themselves and then join the back of the pack, ensuring a clean re-start without slower cars impeding those racing for the leading positions.
- Cars which were in the pit lane when a race is suspended will now be allowed to re-join the cars on the grid in the position they were in when the race was suspended.
- Drivers may no longer leave the track without a justifiable reason, i.e. cutting a chicane on reconnaissance laps or ‘in’ laps to save time and fuel.
- Drivers may no longer move back onto the racing line having moved off it to defend a position.
- One three-day test will be carried out during the season, formerly there were none.
- All stewards’ decisions which are not subject to appeal are now in one place instead of being in various places within the regulations.
- All tyres allocated to a driver may now be used on the first day of practice; formerly only three sets were permitted.
they have altered the defending lines that can be adopted by the driver - its a shame you nearly have to let through a faster car and there are hardly any provisions of defensive driving now..
i for one enjoyed Michael astounding defensive drive against hamilton - i cant think of anyone else who has been able to hold Hamilton for that long.
