Nueva Reglamentación 2012:

Compared to the major changes introduced for 2011 - DRS, KERS, Pirelli tyres etc. - those for the 2012 season may seem relatively minor. Some, however, will still have a significant impact…

No blown diffusers
The FIA is clamping down on engine mapping and exhaust positioning to minimise designers’ use of exhaust gases in a car’s aerodynamics, effectively outlawing blown diffusers.

Crash tests
There will be tougher side impact testing and new cars must now pass all required FIA crash tests prior to any on-track testing.

Safety car
During a safety-car period, 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.

Driving etiquette
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, and drivers may no longer move back onto the racing line having moved off it to defend a position.

Race suspensions
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. Cars which were in the pit lane when the race was suspended will now be allowed to re-join the cars on the grid in the position they were in at the time of the race suspension.

Testing
In addition to the established pre-season tests, one three-day test will be carried out during the season. Formerly there was none.

Tyre allocation
All tyres allocated to a driver may now be used on the first day of practice. Formerly only three sets were permitted on the opening day of the Grand Prix weekend.
