McLaren's test and development driver Stoffel Vandoorne won the GP2 championship on Sunday following a fourth place finish in the Russian Grand Prix sprint race.
Vandoorne has dominated this year's championship with five victories and 13 podiums, giving him an insurmountable lead of 108 points over Alexander Rossi with four races remaining.
However, Vandoorne's title success is no guarantee of an F1 drive next year as McLaren has confirmed Fernando Alonso and Jenson Button as its race drivers and few options remain elsewhere for 2016. What's more, McLaren has Kevin Magnussen as its official reserve driver this year, who beat Vandoorne to the 2013 Formula Renault 3.5 title and will act as further competition for a drive elsewhere on the grid next year.
The last three GP2 champions - Jolyon Palmer, Fabio Leimer and Davide Valsecchi - have all failed to make the step up to F1, but Vandoorne's achievement is made more impressive by managing to take the title in just his second year in the championship.
Victory in Saturday's shortened GP2 feature race in Russia means Manor driver Rossi looks likely to finish second in championship, with Rio Haryanto 43.5 points behind in third and just five points ahead of Sergey Sirotkin in fourth.
