Sandown qualifying explained

One session, two races, 52 drivers – here's how qualifying will play out at the Wilson Security Sandown 500.

We've had the final practice session this morning, open to all drivers after the co-drivers completed two of the three sessions yesterday.

From there, one 20-minute session will run at 11.50am open to all drivers.

The times set determine the starting position for the co-drivers in qualifying race one – 20 laps around the 3.1km Sandown circuit.

Those finishing positions determine where the main drivers will start when they jump in the cars for another 60km race.

Where they finish sets the grid – so the winner takes ARMOR ALL Pole Position.

There are no Championship points on offer today, so the drivers will be going all out for that front row start in the 500.
