The World Motor Sport Council has rubber-stamped new power unit regulations put forward by Formula 1 stakeholders for the 2017 season and beyond, which will guarantee supply, a reduction in cost, power convergence and greater noise.
As part of plans to overhaul the sport next year, which includes already agreed chassis rules, the FIA wanted the concerns about the new power units to be addressed too, namely the four aformentioned areas of supply, cost, power and noise.
Those matters have been addressed, with agreement to reduce cost of supply by £780,000 (€1m, $1.14m) per season and in 2018, the cost will drop by a further £2.3m (€3m, $3.4m).
These cost savings will be driven by "changes to the Sporting and Technical regulations in 2017 and 2018, with a progressive reduction of the number of power unit elements per driver per season."
In order to avoid a repeat of Red Bull's engine woes last year, manufacturers will have an "obligation to supply" which will likely see the FIA step in and enforce a manufacturer to offer engines to a rival should they find themselves without an alternative.
The controversial token system will be removed from 2017. It's hoped that opening up development will allow manufacturers to catch-up with one another, creating a level-playing field.
Additionally, "constraints on power unit part weights, dimensions and materials, and on boost pressure" will be introduced in 2017 and in 2018 to reduce costs and avoid a 'spending war'.
Finally, the engine sound will be addressed, with the FIA confirming that manufacturers are conducting "promising research" into further improving the sound of the current power units, with the aim of implementation by 2018 at the latest.
