The FIA World Motorsport Council (WMSC) concluded their their second FIA Sports Conference in Munich, Germany on Thursday 26 June 2014 and agreed on the changes for the 2015 Formula 1 season.

One of the big changes for 2015 will be standing starts after a safety car period.

The full detail of changes for the 2015 Formula 1 Season are listed below.

Power units

• The number of engines permitted by each driver in a season will be four. However, if there are more than 20 races in a season, the number will increase to five.
• The penalty for a complete change of Power Unit will be starting from the back of the grid, not the pit lane.

Aerodynamic testing

•  The number of wind tunnel runs will be reduced from 80 hours per week to 65 hours per week.
• Wind-on hours are to be reduced from 30 hours per week to 25 hours.
• Computational Fluid Dynamics (CFD) usage is to be reduced from 30 Teraflops to 25 Teraflops.
• Two periods of tunnel occupancy will be allowed in one day (rather than only one).
• Teams will only be able to nominate one wind tunnel in one year.

Testing

• There will be three pre-season tests of four days each in Europe in 2015 (currently teams are able to test outside Europe). This will be reduced to two tests of four days in 2016.
• There will be two in-season tests of two days each in Europe (instead of the current four). Two of these four days must be reserved for young drivers.

Car specification at an Event

• The current restrictions to the parc fermé will now apply from the start of P3 instead of the start of qualifying.

Wheels and tyres

• The ban on tyre blankets will be rescinded for 2015. This will be re-discussed if and when the wheel and tyre diameter increases in the future.

Personnel Curfew

• The Friday night curfew will be extended from six to seven hours in 2015 and will increase to eight hours in 2016.

Safety Car restarts

• Safety Car restarts will now be a standing start from the grid. Standing starts will not be carried out if the Safety Car is used within two laps of the start (or restart) of a race or if there are less than five laps of the race remaining.

Changes to 2015 Technical Regulations

• A number of changes have been made, including:
• A number of new regulations for the noses to ensure improved safety and to provide more aesthetically pleasing structures.
• A number of new regulations concerning skid blocks to ensure that they are made from a lighter material (titanium) and are better contained.
• New regulations to ensure that the brake discs rotate at the same speed as the wheels.
• A two-stage wheel fastener retaining system is now compulsory.
