Switzerland's Neel Jani, behind the wheel of a Porsche 919 Hybrid, stayed on pole position for the Le Mans 24 Hour Race on Thursday when the third qualifying session was red-flagged due to heavy rain.

As a result of the conditions, most of the 60 cars taking part were unable to improve on their times set on Wednesday night.

The last section of qualifying is due to take place later Thursday but with the surface still wet, it's unlikely that challengers Audi or Toyota will be able to better Jani's time of 3min 19.733sec set Wednesday.

The two Porsche 919 Hybrids are due to occupy the front row followed by the Toyota TS050 Hybrids and the Audi R18s behind them on the third row.

This year's Le Mans -- the 84th running of the classic endurance race -- starts at 1300GMT Saturday and will be flagged off by Hollywood superstar Brad Pitt.
