The World Motor Sport Council (WMSC), which has met in Munich, has agreed a number of regulation changes for 2015.

The last date at which the sporting and technical regulations can be changed without unanimous agreement has been changed from 30 June to 1 March each year, starting from 2015.

Changes to 2015 Sporting Regulations

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The ban on tyre blankets will be rescinded for 2015.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.

"How about a spec car and engine, should cut down the cost."

"The safety car was introduced to lose less time in case of a calamity thet would otherwise need a restart. Also to make it easier to safely clean the track of debris without having to stop the race.
These effects will be lost thanks to this.
Other regulations also do not seem to be towards improving the show.
Last time I checked there was an endurance championship, why merge it with F1?"

"Drivers must stop for strawberry flavoured lollipop breaks every 15 laps, except on the last race of the season if it is in Bahrain and under safety car conditions, when they must stop every twelve laps and the lollipops must be honey flavoured"

"As I understand it, F1 cars will circulate behind the safety car until the restart from the grid. So they'll trundle round, going through any on-track debris for a few laps. So the flow of the race is disrupted, cars can still get punctures etc from debris. Tyres will get cold or do the teams get to change to heated tyres before the restart? The outcome is a lot of time wasted....a waste of time...literally! What happens to the TV schedules? Yet more utter nonsense from the powers that be. "

"Standing start after safety car will almost certainly help bring out the safety car. Very safe, indeed (not). There are so many things that could and perhaps should be changed, but these are not them. Why do they bother?"

"We'll, I may as well add my 2 cents...Standing restarts, what are they trying to accomplish here??? This is up there with some of the stupidest idea's in F1 I've ever heard, maybe even worse then double points for the final race. "

"As for restarts after a safety car being a grid line up, why? The current position of cars restarting themselves after the safety car peels off isn't broken! So why fix it. This ruling will just waste time and money! Who thinks these ideas up? Are they in the real world? I don't think so, just look where the sport is now, it's at its lowest point for years and years and it's all down to these busybodies!"

"I do not agree that tyre warming blankets should ever be banned. In my opinion it will be too dangerous for cars with cold tyres to come out of the pits and then try to race those cars they come out next to! How many times will cars come out with cold tyres, try to race and crash straight away into other cars or just by themselves? Disasters just waiting to happen! "

"How many cars sustain damage on the first corner after a race start. I cant see how having the possibility of many restarts will help to reduce the cost of running a F1 team. Will these restarts require all the normal start line procedures such as tire warmers etc if so its going to slow down the show and any excitement generated up to the restart will go of the boil. If they intend to dispense with tire warming the first few laps will be dangerous and probably cause more crashes and then even more safety restarts! as for sparking skid blocks, less running, double points etc. I don't know who dreams up these ideas but it does make you wonder if the best brains are in F1. If they ban wings front and back go back to fat stick tires and mechanical grip they coul;d forget about all the cost of running wind tunnels and CFD models."
