The reintroduction of active suspension is one of four approaches under evaluation for 2018, with the FIA understood to be considering clarifying the existing regulations ahead of the first pre-season test at Barcelona that starts on February 27 in the interim.

Debate about pre-loaded suspension systems has dragged on for several weeks, after Ferrari asked the FIA for clarity regarding the devices helping aerodynamic performance.

As a result, four options, one of which is the reintroduction of active suspension for the first time since it was outlawed ahead of the 1994 season, are being considered based on a document drawn up by McLaren.

Given the scale of the change, if agreed upon by the teams and the FIA, such a regulation change wouldn't come into force until 2018 at the earliest.

The active suspension proposal suggested the standardisation of the actuators would prevent a costly technical arms race.

The proposal also argues active suspension would "bring F1 into the 21st century" technologically.

Should this route be pursued, an active suspension proposal submitted by Mercedes in 2014 has been suggested as a good starting point for defining a four-channel system that would allow teams to control heave and roll electronically.

A second option suggests tightening up the suspension regulations to prevent passive systems designed to influence the aerodynamic platform.

This is based on a Ferrari proposal to interpret the original decision banning active suspension more strictly and would require a change to the wording of Article 3.14 of the technical regulations, which governs aerodynamic influence.

The third option involves exempting suspension systems from the technical regulations governing aerodynamic influence.

This would effectively allow passive systems designed to control the aerodynamic platform, although the regulations would stop short of allowing designs such as FRIC (front-to-rear interconnected) suspension to return.

While it would eliminate question marks over the legality of certain systems, there are concerns this would prove expensive.

The final option is to retain the existing regulations, but with the FIA carrying out more checks to ensure compliance and teams being required to submit documentation explaining their suspension designs.

The four options will form the basis of an ongoing discussion, which will shape the interpretation of the regulations this year and wider changes potentially made for 2018.
