The FIA, FOM and Formula 1 teams - who collectively meet in the Strategy Group - have announced a raft of changes, the first of which will be introduced at this summer's Belgian Grand Prix.
There will be a clampdown on driver aids beginning from the race at Spa Francorchamps, while other alterations have also been announced.
Honda has been given an extra power unit for this season, while power unit regulations have also been tweaked.
Intriguingly, the Strategy Group has confirmed that they have discussed 'exciting' changes to the qualifying and race format which could be introduced from next season.
"Increased restrictions on driver aids and coaching received unanimous support and will be rapidly implemented, starting from this year's Belgian Grand Prix - with particular emphasis on race starts - and in 2016," read a statement released by the FIA.
"These measures will bring back the driver in full control of the car, enhancing races excitement and unpredictability.
"Following the Austrian GP, an overhaul of the power unit penalties has been unanimously agreed and will be submitted to the F1 commission via an express fax vote for adoption at the World Motorsport Council in Mexico City next week, together with changes to the exhaust system that will improve engine noise for 2016.
"Furthermore, it was agreed to allow an extra power unit per driver in the first year to any new manufacturer entering the championship and, for the sake of fairness, the measure will apply retroactively to Honda for the 2015 season.
"Mandate has been given to the FIA and FOM to propose a comprehensive set of measures for power unit development and cost and supply, including full review of the token system, increase in race fuel allowance, limits on the usage of engine dynamometers etc.
"Increased freedom of choice for tyre compounds has been confirmed and the modalities are being finalised with Pirelli for 2016.
"A new set of regulations aimed at achieving faster and more aggressive looking cars for 2017, to include wider cars and wheels, new wings and floor shape and significantly increased aerodynamic downforce has been outlined and is currently being assessed by the teams.
"Several exciting and innovative changes to the qualifying and race weekend formats have also been discussed and are being evaluated by the FIA and FOM for 2016 introduction."
