Jake Humphrey presents coverage of the Korean Grand Prix, the 16th of 20 races in the 2012 calendar.
The race has proved eventful since its introduction in 2010, and Sebastian Vettel's victory last year helped clinch a second consecutive constructors' championship for Red Bull.
Double world champion Vettel is finding the going tougher this season, with 2010 race winner Fernando Alonso leading the challenge as he pursues a first world title for six years. Lewis Hamilton is another former world champion vying to stay in contention, and he has finished runner-up at the Korean International Circuit in the two previous years.
Commentary comes from Ben Edwards and David Coulthard, with expert analysis by Eddie Jordan.
