The first session will last 16 minutes with the slowest driver eliminated once seven minutes have lapsed. Subsequently the slowest driver is eliminated every 1 minute 30 seconds thereafter until the chequered flag leaving 2 drivers in the final 1 minute 30 seconds.

The race for pole position will begin in Q3 - which will last 14 minutes - with the first elimination coming after five minutes until the fastest two are left to battle it out for top spot in the final 90 seconds.

Ecclestone, who also made it clear that it was not his idea and that he preferred some form of handicap to shake up grids, said that the new system would have to wait until Spain in May. We feel that the qualifying at the moment is really good.
