The 2018 Formula 2 season will mark the debut of the next-generation car and is likely to boast one of the series’ strongest ever grids.

2017 champion Charles Leclerc will race with the Sauber Formula 1 team in 2018, the 32nd driver to graduate from the series since its inception in 2005.

Russian Time and Rapax have exited the series but will be replaced by Formula V8 3.5 teams Charouz Racing and Fortec Motorsport, as well as the returning Carlin.

A fourth new entry is rumoured but is yet to be confirmed, with the identity of the outfit also unknown.

The most controversial entry next year is undoubtedly the introduction of the cockpit safety device; the halo, which will also be in F1 next season.

Six of the 22 drivers are confirmed for the 2018 season, we assess their relative chances and look at who will join them on the grid next year.
